Introducción: la babesiosis es una zoonosis causada por parásitos del género Babesia spp, en Venezuela son escasos los reportes. En casos graves de la enfermedad se puede presentar como síndrome de distrés respiratorio agudo (SDRA), cuyo pronóstico dependerá de la edad del paciente. Caso Clínico: masculino de 42 años de edad, veterinario, ingresa al área de emergencia por cuadro de disnea asociado a tos seca con evolución a síndrome de distrés respiratorio agudo ameritando ventilación mecánica no invasiva. Se realiza fibrobroncoscopia con cepillado bronquial que reporta resultado de reacción en cadena de polimerasa (PCR) positivo para Babesia spp, iniciando tratamiento con clindamicina y azitromicina presentando evolución clínica satisfactoria y egresa. Discusión: el caso clínico presentado trata de paciente masculino con factores de riesgo para el contacto con garrapatas del género Ixodes, lo habitual es que las infecciones por este hemoparásito sean de forma asintomática en pacientes inmunocompetentes, sin embargo, en ocasiones puede progresar a un cuadro clínico severo en el que destacan los cuadros respiratorios graves donde el abordaje terapéutico temprano y oportuno es fundamental para garantizar evolución satisfactoria. Conclusiones: el diagnóstico de babesiosis debe sospecharse en pacientes con manifestaciones clínicas y características de laboratorio típicas siendo fundamental los antecedentes epidemiológicos como en el caso presente cuyo aspecto laboral estableció riesgo para contacto con la garrapata. Recientemente se ha observado aumento de número de casos en Venezuela, por lo que se debe sospechar dicha patología en pacientes que acuden con clínica similar ya que el pronóstico dependerá del inicio temprano de tratamiento.

Introducción: La parasitosis intestinal afecta principalmente a niños, pudiendo causar deficiencia en el aprendizaje, falta de desarrollo y crecimiento; se constituye un problema de gran importancia al que se enfrentan las instituciones de Salud Pública y Ambiental, por lo que se requiere conocer la epidemiología y los parásitos más prevalentes a nivel regional. El objetivo del presente estudio fue identificar los parásitos intestinales que prevalecen en niños de 1 a 10 años que se atendieron en una unidad municipal de salud sur de Quito. Métodos: El presente estudio observacional de corte transversal, analiza una población pediátrica atendida en la Unidad Municipal de Salud Sur de la ciudad de Quito. Se analizan los examenes coproparasitarios con estadística descriptiva. Resultados: Se examinaron 195 pacientes, 68 de ellos (34.87 %), presentaron cuadros de parasitosis intestinal (IC 95 % 28.%-41.6 %). Sin diferencias en el sexo. Un total de 42 niños (21.54 %), tuvieron monoparasitismo, y 26 (13.33 %) poliparasitismo. En el rango de 1 a 5 años, 21 niños (21 %) presentaron Entamoeba histolytica, 18 niños (18 %) con Entamoeba coli, 17 niños (17 %) presentaron Blastocystis hominis, 11 niños (11 %) con Endolimax nana. Del rango de 6 a 10 años, 11 niños (11 %) con Entamoeba coli, 8 niños (8 %) con Blastocystis hominis, 5 niños (5 %) con Entamoeba histolytica. Conclusión: Los niños menores de 5 años son los más afectados. La Entamoeba histolytica y Entamoeba coli son los parásitos más prevalentes.

The present study was carried out in the neighborhoods "Hermanos Cruz", "Carlos Manuel", "Montequín" and "Calle Martí" belonging to the municipality of Pinar del Río, with the aim of identifying causal plague organisms associated with urban trees in the city of Pinar del Rio, Cuba. A floristic inventory of forest trees was carried out up to the family and species level, as well as the collection of samples of plant organs with symptoms of parasitic diseases and/or the presence of phytophagous insects. The inventory of urban trees in the city of Pinar del Río revealed 13 forest species belonging to 9 botanical families and 12 genera. The most represented family was Meliaceae. In addition, the "Hermanos Cruz" distribution presented a greater abundance of forest species. The species of urban trees serve as hosts to 21 harmful organisms that include eight causal agents of parasitic diseases, 3 orders, 11 families and 13 species of phytophagous insects, with a greater representation of Hemiptera and Lepidoptera. Harmful organisms showed a greater presence in the forest species like Callophylum antillanum, Grevillea robusta, Acasia mangium, Hibiscus elatus, Gmelina arborea, Tectona grandis y Eucaliptus sp.

La fascioliasis es una enfermedad parasitaria emergente que afecta al ganado bovino de Perú. El objetivo de esta investigación fue determinar los factores asociados a la prevalencia de Fasciola hepática en bovinos faenados en la provincia de Huaura. Se evaluaron datos sobre decomisos de hígados, procedencia, edad, sexo y mes del año, provenientes de los registros de 2198 bovinos, entre mayo y agosto del 2018, donde el 59,51 % de los hígados estuvieron infestados con Fasciola hepática. Además, se registró un mayor decomiso (p < 0,05) en los bovinos procedentes de los distritos Churín (67 %), Oyón (63 %) y Ambar (57 %), ubicados en las zonas de mayor altitud (2082-3620 m s.n.m.) y precipitación pluvial (30-206 mm). Asimismo, la prevalencia fue mayor en mayo (69 %, p < 0,05) en comparación con junio (61 %), julio (58 %) y agosto (42 %) y la edad de los animales fue un factor significativamente asociado al decomiso de hígados (p < 0,05), siendo mayor en el ganado de 5 años o más (62 %) y menores de 2 años (64 %) en comparación a los de 2 años (51 %), 3 años (53 %) y 4 años (52 %). Por otra parte, el decomiso de hígados fue mayor en hembras (61 %, p < 0,05) que el registrado en machos (51 %). La prevalencia de F. hepática en bovinos faenados en la provincia de Huaura es elevada, donde la procedencia del ganado, el sexo, la edad y el mes del año estuvieron asociados con el mayor decomiso de hígados.

Background: parasitosis has high incidence rates in the world child population, conditioned by poor sanitary habits and other associated risk factors, a situation also affecting our country. Objective: to characterize children with parasitism who attend kindergarten from the health area of the "Manuel Fajardo Rivero" University Polyclinic in Las Tunas. Methods: a descriptive and cross-sectional study was carried out in children attending four kindergarten of this health area, from 6 September to 5 November 2021. From a universe of 706 infants, a sample of 81, aged between 2 and 6 years, was positive on stool samples. The variables evaluated included: age group, sex, associated risk factors, parasitic species, clinical symptoms and medical treatment. Results: infants of the sixth year of life predominated (29.6 %), with males (64.2 %) being the most affected. Untreated or unboiled water consumption (44.5 %) was the most commonly found associated risk factor. Blastocystis hominis (42.0 %) was identified as the most frequent parasitic species; abdominal cramps (48.1 %) as a clinical symptom and Secnidazole (80.2 %) was the most prescribed drug. Conclusions: children with parasitism were characterized from four kindergarten of the health area of "Manuel Fajardo Rivero" polyclinic.

Introducción. La enfermedad de Chagas es una parasitosis endémica en Latinoamérica transmitida por triatominos. Está asociada a factores de riesgo como la pobreza y la ruralidad. Después de la infección aguda, un tercio de los pacientes presenta compromiso del corazón, el aparato digestivo o el sistema nervioso central, en tanto que los dos tercios restantes no presentan este tipo de compromiso secundario. La inmunosupresión farmacológica rompe el equilibrio entre el sistema inmunitario y el parásito, lo cual favorece su reactivación. Caso clínico. Se presenta el caso de un hombre de 58 años procedente de un área rural colombiana, con diagnóstico de mieloma múltiple resistente a los fármacos de primera línea de tratamiento, que requirió un nuevo esquema de quimioterapia y consolidación con trasplante autólogo de células madre. Después del trasplante, presentó neutropenia febril. Los estudios microbiológicos iniciales fueron negativos. En el frotis de sangre periférica, se demostraron tripomastigotes y se diagnosticó enfermedad de Chagas aguda posterior al trasplante. Se inició el tratamiento con benznidazol. La evolución del paciente fue satisfactoria. Conclusiones. La serología positiva para Chagas previa a un trasplante obliga a descartar la reactivación de la enfermedad en caso de neutropenia febril. Se requieren más estudios para determinar las herramientas que permitan estimar la probabilidad de reactivación de la enfermedad y decidir sobre la mejor opción de relación entre costo, riesgo y beneficio de la terapia profiláctica.

The objective of this manuscript is to provide selective examples of the work of the Pan American Health Organization/ World Health Organization (PAHO/WHO) Collaborating Centre for Research and Training in Parasite Epidemiology and Control which contribute to the WHO goal of eliminating neglected tropical diseases by 2030. This PAHO/WHO CC specifically aligns its activities with the Sustainable Development Goals and with the goals outlined in the WHO Road Map for Neglected Tropical Diseases 2021-2030. Its role is to contribute to advancing global action on NTDs, primarily through policy development and knowledge translation. Three important projects have recently been completed: 1. Finalizing the Monitoring and Evaluation Framework for the NTD Road Map (published May 2021; this PAHO/WHO CC was a member of the working group); 2. Developing new guidelines for the preventive chemotherapy of Taenia solium taeniasis (published September 2021; this PAHO/WHO CC was co-Chair; and 3. Formulating a policy brief on deworming for adolescent girls and women of reproductive age (published January 2022; this PAHO/WHO CC is co-lead). These projects are the result of the integration of expertise and experience from multiple partners, including from PAHO and WHO (where both organizations provided key leadership), this PAHO/WHO CC, government ministries, civil society organizations and universities, among others. In conclusion, this PAHO/WHO CC contributes timely guidance to country-led evidence-informed public health policy, to cost-effective program implementation and to the identification of priority research topics -- all focused, ultimately, on eliminating NTD-attributable morbidity by 2030.

Cystic echinococcosis (CE) continues to be one of the main health problems in cattle regions. Controlling the disease requires new therapeutic strategies. Main: To evaluate the results of an intervention program based on the directly observed antiparasitic treatment of dogs in an endemic area of CE. Materials and methods: A quasi-experimental study of a single cohort of dogs from a CE endemic area was conducted. To identify infected dogs, stool samples were analyzed for antigens by enzyme-linked immunosorbent assay, before and after the direct and observed administration of praziquantel 5 mg per kg orally every 30 days for 3 consecutive months once a year for two years. Results: A total of 252 dogs entered the study, of which 119 (47%) dogs presented positive results for E. granulosus at the beginning of the intervention. The adverse effects that occurred with the administration of praziquantel were vomiting (13%), diarrhea (2.4%), and lethargy (2%); 229 dogs completed the 2 treatment cycles with praziquantel. The presence of some positive coproantigen was evident in 03 (1.3%) dogs after the intervention. In conclusion: Antiparasitic chemotherapy administered directly to dogs was able to reduce the prevalence of canine echinococcosis after 2 years of intervention. [ABSTRACT FROM AUTHOR]

Introduction: parasitic diseases are widely distributed worldwide, and despite the efforts of health agencies, they continue to be a public health problem, especially in developing countries such as Paraguay. Objectives: to determine the prevalence of intestinal parasitosis in children attending a public school in a suburban neighborhood of the city of Asuncion, Paraguay. Methods: descriptive cross-sectional study, in which 42 fecal samples of children aged 5 to 8 years were analyzed; collected during 2018 in a public school in Asuncion. Parasitological analysis was performed by direct examination of feces in saline solution, lugol, and concentration with Burrows' method. The absolute and relative frequency of parasites present was established. Results: the presence of commensal parasites was identified in 14,2 % of the samples, corresponding to Entamoeba coli cysts in 67 %, while the remaining 33 % corresponded to vacuolated forms of Blastocystis hominis. Conclusions: the socioeconomic conditions of the population evaluated probably do not make them so susceptible to enteroparasitosis. However, we emphasize the need to continue providing health education along with basic services for excreta disposal and periodic deworming as basic control measures in future interventions in both rural and urban populations.

Objective. To identify the abundance and prevalence in infection by digestive parasites (DPs) and their seasonal distribution in dogs from Aguascalientes, Mexico. Materials and Methods. A statistically representative sample (n=927) systematically selected (first in each 10), of stray or owners-surrendered dogs at a local animal control and welfare center was examined. Immediately after legal euthanasia (pre-anesthetic plus anesthetic overdose), the entire intestine was removed, and intestinal contents were sieved; macroscopically visible helminths were collected; a stool sample was then examined in duplicate by flotation, McMaster, and Lugol's-stained smear. Results. The prevalence of DPs was 42.8%. Elevated prevalence values were detected among puppies (60.6%), in dogs with lower body weight (72.7%), also in stray dogs (57.5%) compared with those voluntarily surrendered by their owners (37.5%; p<0.01); additionally, more cases were found during temperate seasons (51.0 vs 33.1%; p<0.01). The DPs prevalence values were determined: Dipylidium caninum (26.2%), Taenia spp. (4.0%), Giardia spp. (13.6%), Cystoisospora spp. (7.8%), Sarcocystis spp. (5.3%); Toxocara canis (14.0%), Ancylostoma caninum (12.9%), Uncinaria stenocephala (4.2%), Toxascaris leonina (0.5%), and Oncicola canis (0.1%). The DPs reached a high prevalence with hundreds of adult forms in the intestine and thousands of eggs or oocysts per gram of feces. Conclusions. These results indicated a high prevalence of DPs in dogs of central Mexico, especially in the population segment constituted by stray, young and underweight animals, which is relevant in public health due to its recognized zoonotic capacity.

Parasitic diseases are considered to be one of the most prevalent pathologies worldwide. They are characterized as one of the most critical sanitary problems in cattle, causing a decrease in the productive capacity of parasitized animals, which translates into economic losses. Intestinal parasitism in cattle is caused by protozoa and helminths, and its manifestation is generally multi-etiological. Clinical signs in gastrointestinal parasitism may vary depending on parasite load, parasite species, and host immunity. This research aimed to determine the prevalence of the main parasitic families affecting cattle in the central province of the department of Boyacá. A cross-sectional study with simple random sampling was carried out, where 716 fecal samples were taken and processed using a modified Ritchie technique. An overall prevalence of 95,6% was determined, and the most prevalent families were Trichostrongylidae, Eimeriidae, Taeniidae, and Trichuridae. The age showed no significant statistical association with most of the parasitic families, except for the Strongyloididae family. The breeds showed a correlation with the Trichostrongylidae, Eimeriidae, Strongylidae, Chabertiidae, and Taeniidae families. The results show the high prevalence of GIP (gastrointestinal parasites) in cattle of the central province of the department of Boyacá. [ABSTRACT FROM AUTHOR]

Objective. To identify, describe and determine the frequency of species of the genus Eimeria from goat feces from the state of Nuevo Leon, Mexico. Materials and methods. From 403 samples of goat excreta from 13 municipalities of Nuevo Leon, Mexico. Subsequently, after sporulation of the parasite dispersal forms (Oocysts), identification was made according to their morphology and morphometry by means of histograms and linear regression analysis. Results. A total of 60.29% of the animals sampled were positive for the presence of oocysts of Eimeria spp. The municipalities in which this parasite was most frequently detected were Ramones and Pesquería with 100% of positive samples, while a lower frequency was observed in the municipality of Aramberri with 3.4%. The morphological and morphometric analysis of the sporulated oocysts allowed the identification of 8 different types of Eimeria in the group of animals studied: E. caprina, E. caprovina, E. christenseni, E. ninakohlyakimovae, E. jolchijevi, E. alijevi, E. arloingi and E. apsheronica. Conclusions. Most of the identified Eimeria spp. showed a high degree of polymorphism. According to their morphometric characteristics, eight species were identified, including E. apsheronica, which has not been previously described in Mexico. Further studies of Eimeria species circulating in goats in Mexico are required. [ABSTRACT FROM AUTHOR]

Background: The treatment of choice for Pulmonary Hydatid Cys (PHC) is surgical resection. There is currently controversy about the superiority of surgery with capitonage (SC) versus surgery without it (SWC). Aim: To compare the results of conservative surgery with capitonnage and versus surgery without capitonnage using Propensity Score Matching (PSM). Materials and Method: A retrospective analytical study was carried out with patients with PHC treated surgically at the Guillermo Grant Benavente Hospital, Concepción, Chile, between January-1995 and December-2018. A PSM was performed with a 1:1 ratio. Results: Conservative surgery was done in 165 cases, 101 SC and 64 SWC. After matching, 53 SC and 53 SWC operated patients were obtained. No significant differences were observed in the presence of persistent air leak (9.4% vs11.3%, SC vs SWC respectively, p 0.75), empyema (3.8% vs 0%, p 0.49), days with pleurotomy (9.1 ± 8.9 vs 10.1 ± 10.7, p 0.39), nor days of postoperative stay (10.4 ± 9.0 vs 11.7 ± 11.9, p 0.22). Conclusion: The SWC demonstrated comparable results to the SC technique in the conservative surgical treatment of PHC. [ABSTRACT FROM AUTHOR]

Neurocysticercosis is an infection of the central nervous system caused by the accidental ingestion of eggs of Taenia Solium, constituting the most frequent parasitosis of the system itself. It is a common problem in many Latin American, Asian and African countries; in endemic areas, it is considered the main etiology of late-onset epilepsies. The case of a 39-year-old male patient with a history of behavioral disorders and several seizures for a year is presented. For this reason he was transferred to the Main Military Hospital of Luanda and admitted to the Psychiatry Service with a presumptive diagnosis of hysterical neurosis. A month after his discharge, he was referred again this time to the Neurology Service of the hospital itself. A physical examination was performed, supplementary tests were indicated, and a chest X-ray and tomography were performed, which showed images suggestive of active neurocysticercosis. Pharmacological treatment and physiotherapy were indicated. After eighty days, the patient was discharged, conscious, oriented, and asymptomatic. The objective of the presentation is to draw the attention of specialists who collaborate in different parts of the world as it is an extremely rare disease in Cuba and which they must face with certain frequency in other latitudes.

La neurocisticercosis es una infección del sistema nervioso central provocada por la ingestión accidental de huevos de Taenia Solium, constituyendo la parasitosis más frecuente del propio sistema. Es un problema común en muchos países latinoamericanos, asiáticos y africanos; en áreas endémicas, es considerada la principal etiología de las epilepsias de inicio tardío. Se presenta el caso de un paciente de 39 años de edad, de sexo masculino, con historia de alteraciones del comportamiento y varias crisis convulsivas desde hacía un año atrás. Por este motivo fue trasladado al Hospital Militar Principal de Luanda e ingresado en el Servicio de Psiquiatría con diagnóstico presuntivo de neurosis histérica. Al mes de su egreso fue remitido nuevamente esta vez en el Servicio de Neurología del propio hospital. Se le realizó examen físico, se le indicaron complementarios y se le realizó rayos X de tórax y tomografía que mostraron imágenes sugestivas de neurocisticercosis activa. Se le indicó tratamiento farmacológico y fisioterapia. Lugo de ochenta días el paciente fue egresado, consciente, orientado, asintomático. El objetivo de la presentación es llamar la atención a especialistas que cumplen colaboración en diferentes partes del mundo al ser una enfermedad extremadamente rara en Cuba y a la que se deben enfrentar con cierta frecuencia en otras latitudes.

Cutaneous leishmaniasis is an endemic tropical parasitic disease with a worldwide distribution. It can present in atypical forms that mimic other dermatoses. These can make diagnosis difficult and often delayed, which can result in treatment resistance. This situation is more frequent in chronic cutaneous leishmaniasis (CCL) (i.e., >1 year), in which chronicity, added to the possible failure of an initial treatment, can completely change the appearance of the lesions. Although CCL has been widely described in the Old World, it has become increasingly relevant in the New World due to an increasing number of reported cases. Below, we present a series of cases of CCL from different geographical areas of Colombia that were evaluated in health brigades in recent years and in which clinical diagnosis was a challenge. We seek to contribute to the medical knowledge of these variants and alert about their presence in the New World, especially in an endemic country like Colombia. [ABSTRACT FROM AUTHOR]

La miasis se produce por la infestación con larvas de especies de moscas que afectan los tejidos u órganos de los vertebrados, incluido el ser humano. Puede clasificarse por caracterización entomológica o según el tropismo de las larvas en los tejidos. La miasis intestinal es poco frecuente y de difícil diagnóstico dada su sintomatología inespecífica, p or lo que la única forma de confirmar el caso es mediante la identificación de las larvas expulsadas.Se presenta el primer caso reportado en el departamento de Nariño (Colombia) de miasis intestinal en un niño de seis años residente en la zona urbana del municipio de Policarpa, proveniente de una familia de nivel socioeconómico bajo, sin acceso a un adecuado tratamiento y sin disposición de aguas residuales y con insuficientes condiciones de saneamiento básico. El caso clínico se asoció con diarrea crónica, dolor abdominal y prurito anal, con la posterior expulsión de una larva cuyas características morfológicas correspondían a las de la mosca Eristalis tenax.

Introducción. La enfermedad de Chagas o tripanosomiasis americana es causada por el protozoo flagelado Trypanosoma cruzi, transmitido principalmente por insectos vectores (denominados popularmente en las diferentes zonas de la Región de las Américas “vinchucas”, “pitos”, “chinches”, “chirimachas” o “kissing bugs”). El parásito es transmitido por vía transplacentaria, transfusiones y, menos frecuentemente, por vía oral o trasplante de órganos. La implementación de políticas públicas y el manejo de la condición clínica requiere ser fortalecido debido a las dificultades diagnósticas y terapéuticas que presenta esta parasitosis sistémica. Para contribuir con ello, la Organización Panamericana de la Salud (OPS) desarrolló una guía para el manejo de la tripanosomiasis americana. Objetivos. Sintetizar las recomendaciones incluidas en la Guía para el diagnóstico y el tratamiento de la enfermedad de Chagas, publicada por la Organización Panamericana de la Salud en 2018, con el fin de presentar el adecuado diagnóstico y tratamiento de la enfermedad de Chagas y abordar aspectos sobre su implementación. Métodos. Se llevó a cabo una síntesis de la guía y sus recomendaciones. Adicionalmente, se realizó una búsqueda sistemática en PubMed, Lilacs, Health Systems Evidence, Epistemonikos y literatura gris de estudios desarrollados en las Américas con el fin de identificar barreras, facilitadores y estrategias de implementación. Resultados. Se presentan 10 recomendaciones aplicables a pacientes adultos y pediátricos con sospecha de enfermedad de Chagas, exposición a T. cruzi y diagnóstico confirmado de enfermedad de Chagas aguda, crónica y congénita. Se identificaron reportes que abordaron aspectos de implementación. Conclusiones. Las recomendaciones buscan proveer estrategias para el diagnóstico y tratamiento oportunos de la enfermedad de Chagas, así como consideraciones para su implementación.

Introduction: Intestinal apicomplexa protozoa are a recognized cause of gastroenteritis. They are endemic in Honduras and their epidemiology varies in different population groups. Objective: To identify risk factors for cyclosporiasis, cryptosporidiosis, and cystoisosporiasis. Materials and methods: We conducted a case-control study in a hospital-based population. We performed the diagnosis using the modified Ziehl-Neelsen staining technique and collected the information from laboratory records and clinical charts. Results: Cyclosporiasis was associated with diarrhea (OR=2.28; 95%CI: 1.10-4.89), weight loss (OR=12.7; 95%CI: 2.49-122.00), watery stools (OR=2.42; 95%CI: 1.26-4.65), and infection with another protozoan (OR=3.13; 95%CI: 1.66-5.95). Cryptosporidiosis was associated with HIV infection (OR=15.43; 95%CI: 3.34-71.22), diarrhea (OR=3.52; 95%CI: 1.40-9.40), lymphopenia (OR=6.16; 95%CI: 1.99-18.98), and green color stools (OR=3.00; 95%CI: 1.23-7.30). Cystoisosporiasis was associated with HIV infection (OR=11.20; 95%CI: 3.53-35.44), diarrhea (OR=7.30; 95%CI: 1.89-28.52), leukopenia (OR=4.28; 95%CI: 1.33-13.75), green color stools (OR=11.59; 95%CI: 1.16-558.60), and Charcot-Leyden crystals (OR=11.59; 95%CI: 1.16-558.60). Conclusions: In this hospital-based population from Honduras, HIV infection was a risk factor for cryptosporidiosis and cystoisosporiasis, but not for cyclosporiasis. [ABSTRACT FROM AUTHOR]

Los parásitos coccidiales afectan varias especies de reptiles a nivel mundial y son responsables de la muerte de cientos de ejemplares cautivos y silvestres en diferentes regiones del planeta. Entre los años 2011 y 2013, cuatro de 108 tortugas verdes (3,70 %) rescatadas por Grupo de Trabajo en Tortugas Marinas del Golfo de Venezuela, a través de la “Red de Aviso Oportuno (RAO)”, presentaron diferentes estadios evolutivos morfológicamente semejantes a Caryospora sp. en heces o tejidos. Los animales infectados fueron juveniles de tortuga verde capturados por pesquerías artesanales. Se les practicaron exámenes físicos, coprológicos y hematológicos. En tres ejemplares se observaron abundantes ooquistes de morfología compatible con Caryospora cheloniae (K001, K002, SB001). Uno de los animales presentó en capa blanca, leucocitos que contenían estructuras parecidas a esporozoitos de Caryospora sp, indicativo de coccidiosis sistémica. Dos de las tortugas se encontraron asintomáticas (K003, SB001), y dos se presentaron clínicamente enfermas con signos neurológicos como movimientos involuntarios de cabeza y aletas, espasmos musculares, movimientos natatorios circulares y depresión. Dos animales murieron (K001, K002), en ambos se encontraron diversos estadios de un organismo coccidial consistente con Caryospora sp. en intestino, además una enteritis necrótica moderada. Este constituye el primer reporte de coccidiosis en tortugas marinas en Venezuela y en el Caribe sur.

Los terpenos y aceites esenciales (AcEs) poseen un amplio espectro de actividades biológicas que pueden ser exploradas en las ciencias veterinarias. En este sentido, su uso ha sido propuesto como una estrategia para enfrentar las crecientes poblaciones de nematodos gastrointestinales (NGI) resistentes a los antihelmínticos (AH) tradicionales. En la presente revisión analizamos 11 manuscritos científicos que, mediante la utilización del enfoque in vivo, evaluaron el potencial AH de plantas ricas en terpenos (PRT) o AcEs en pequeños rumiantes. La especie ovina fue utilizada en el 81% de los trabajos. Brasil es el país que lidera esta línea de investigación seguido de los Estados Unidos de América y la República de Benín. Todos los manuscritos analizados utilizaron la prueba de reducción del conteo fecal de huevos de NGI, mientras que cinco manuscritos emplearon la metodología del test —o prueba— controlado(a). La actividad de las PRT y los AcEs sobre la excreción de huevos de NGI en las heces fue variable, reportándose valores que oscilaron desde un efecto nulo hasta un 97%. Dos trabajos reportaron una reducción en el tamaño de los NGI machos adultos y en la fecundidad de las hembras tras la administración de AcEs. Resulta necesario generar más trabajos que se dirijan a entender las interacciones entre las plantas, sus metabolitos secundarios y los rumiantes que las consumen. Comprender dichas interacciones nos permitirá utilizar estos productos naturales como elementos que ayuden a mejorar la nutrición y la sanidad de ovinos y caprinos en diferentes sistemas productivos.

Los tumores hepáticos sólidos benignos están formados por un grupo heterogéneo de lesiones. Las parasitosis hepáticas conforman una causa etiológica poco frecuente de tumores hepáticos sólidos benignos. Objetivo. Reportar el caso de un paciente con tumores hepáticos solidos benignos tratado con embolización portal derecha y posteriormente hepatectomía. Caso clínico. Paciente de 60 años, sexo masculino, al cual se le diagnostican múltiples tumores hepáticos sólidos, debido a cuadro de ictericia generalizada. Debido al cuadro sintomático, y al no poder descartar malignidad con las pruebas complementarias, se decide realizar cirugía. Previamente se realiza volumetría de la glándula hepática y embolización portal derecha para aumentar el remanente hepático futuro. Se realiza hepatectomía derecha y segmentectomía hepática IVa. Evoluciona con mejoría del cuadro ictérico y el resultado anatomopatológico informa lesión vinculable a parasitosis hepática. Conclusión. Ante la presencia de un tumor hepático sólido, es necesario descartar etiología maligna de la lesión. Si no es posible descartar esto, o si el paciente persiste con sintomatología, la resección quirúrgica está indicada, teniendo en cuenta el volumen de la glándula hepática y del remanente hepático futuro.

Sin resumen

Presentamos el caso clínico de un joven, proveniente del área rural, con anemia ferropénica severa, sin sangrado evidente, quien requirió transfusión de hemoderivados y múltiples exámenes, donde se descartaron causas hemolíticas, autoinmunes y anemia de enfermedad crónica. En estudios endoscópicos se le documentó uncinariasis masiva como causa de su cuadro clínico. La uncinariasis es una causa subdiagnósticada y potencialmente curable de anemia en nuestro medio. En este artículo hacemos la descripción de un caso clínico, la discusión sobre diagnósticos diferenciales de anemia ferropénica y revisión de la literatura.

El objetivo de este trabajo fue determinar la prevalencia de los hemotrópicos Anaplasma marginale, Babesia spp. y Trypanosoma spp. y las interacciones ambientales y genéticas en vacas en ordeño del Sistema Doble Propósito en el municipio Arauca, Colombia. Se tomó muestra sanguínea de la vena coccígea media a 333 bovinos hembras, de diferentes edades, localizadas en 18 fincas ganaderas y se tomó como criterio de inclusión solo las hembras que estaban en ordeño en cada finca. El muestreo se realizó por conveniencia en época de verano y de invierno. Las muestras fueron analizadas utilizando las técnicas de Wright y Hemacolor®. Los grupos raciales fueron: Cebú (n=157), Criolla (n=14), Criolla x Cebú (n=32), Mestiza (n=64), Pardo x Cebú(n=22), Puro Tauro (n=23), Simental x Cebú (n=16) y Holstein x Cebú (n=5). Mediante tablas de contingencia se determinó la cantidad porcentual de animales positivos a hemotrópicos. Los datos se procesaron en Infostat. El 72,22% de las fincas fueron positivas para A. marginale; 66,66% para Trypanosoma spp. y el 16,66% para Babesia spp. La prevalencia general fue de 43,54%, el hemotrópico más frecuente fue A. marginale, (24,92%), seguido de Trypanosoma spp, (14,41%) y Babesia spp. (4,2%). No se identificaron infecciones mixtas. Se observó asociación significativa (P=0,0001) de las fincas con los tres hemotrópicos; A. marginal fue dependiente del grupo racial (P=0,0046), Babesia spp. y A. marginale presentaron dependencia de época del año (P0,05). Se concluye que en la región de sabana inundable araucana la mayor prevalencia de hemotrópicos estuvo asociada por A. marginale y Trypanosoma spp. animales con predominio taurus son más susceptibles que los criollos y las interacciones están supeditadas al manejo general, programa sanitario, época y localización agroecológica de los predios ganaderos.

Introduction. Chagas disease or American trypanosomiasis is caused by the flagellate protozoan Trypanosoma cruzi, transmitted mainly by insect vectors (popularly known in the different areas of the Region of the Americas as "kissing bugs", "pitos", "chinches", or "chirimachas" or "vinchuchas"). The parasite is transmitted via the placenta and in transfusions, and less frequently, orally or during organ transplantation. Because it was necessary to strengthen the implementation of public policies and the management of clinical conditions, given the diagnostic and therapeutic difficulties that this systemic parasitosis presents, the Pan American Health Organization (PAHO) developed guidance for the management of American trypanosomiasis. Objectives. Synthesize the recommendations included in the Guide for Diagnosis and Treatment of Chagas Disease, published (in Spanish only) by the Pan American Health Organization in 2018, in order to present the proper diagnostic methods and treatment for Chagas disease and to address aspects of its implementation. Methods. A summary was made of the guide and its recommendations. In addition, a systematic search was conducted in PubMed, Lilacs, Health Systems Evidence, Epistemonikos, and the gray literature for studies carried out in the Americas, in order to identify barriers, facilitators, and implementation strategies. Results. Ten recommendations are made. These are applicable to adult and pediatric patients with suspected Chagas disease, exposure to T. cruzi, or a confirmed diagnosis of acute, chronic, or congenital Chagas disease. Reports that addressed aspects of implementation were identified. Conclusions. The recommendations seek to provide strategies for the timely diagnosis and treatment of Chagas disease, as well as considerations for the implementation of such strategies. [ABSTRACT FROM AUTHOR]
