Abstract

For many years, research about social wasps in the Northeast was neglected due to its climatic and vegetative characteristics, insufficient incentive for training researchers to study these animals and perpetuation of low diversity of these groups in arid environments proposed by Ducke. This study carried out a bibliographic survey of research about social wasps in a 40 years period from January/1979 to December/2019, to determine the overall reality of biodiversity and richness knowledge for social wasps species. One hundred and twenty-four (124) social wasp species have been registered in the Northeast Region, distributed among 20 genera. Epiponini stands out with 84 species, followed by Mischocyttarini (24) and Polistini (16). Sergipe is the only state with no studies and records of species thus far. Such results show the importance of continuing taxonomic studies of these insects to expand their geographic distribution and to determine areas for environmental preservation in the Northeastern biomes, i.e., the Caatinga sensu lato, Cerrado and Amazon rainforest and their transition zones, as they have been insufficiently studied and present high potential for new discoveries. We suggest Alagoas, Ceará, Pernambuco and, especially Sergipe as priority areas since there is a lacking data in these states. Finally, we recommend continuing research on species reports in states like Bahia, using the map created herein to choose future study areas.

Abstract

ABSTRACT Chagas disease is an important endemic morbidity in Latin America affecting millions of people in the American continent. It is caused by the protozoan Trypanosoma cruzi, and transmitted through the feces of the insect vector belonging to the subfamily Triatominae. The present conducted an entomological survey of triatomines and analyzed entomological indicators, such as the rate of infestation, colonization, triatomine density and natural infection in rural communities in the municipality of Campinas do Piaui, Piaui State, in the Northeast region of Brazil. Data on the search of triatomines performed in 167 domiciliary units (DUs), harvested during the period of February to July 2019, in 12 rural communities were analyzed. The capture of triatomines occurred in all studied communities, being 76 the number of positive DUs, of the 167 surveyed, presenting a global rate of infestation of 45.51%. Two triatomines species were collected: Triatoma brasiliensis (98.49%) and T. pseudomaculata (1.51%), the first was found in the domiciliary and peridomiciliary areas, while the second was captured only in peridomiciliary areas. The index of colonization was 17.1%. Natural infection was observed only in 5.44% of T. brasiliensis samples. The entomological survey was conducted in rural communities, showingthe risk of transmission of Chagas disease to the local population, requiring continuous entomological surveillance and vector control.

Abstract

This manuscript aimed to evaluate the seroprevalence of Chagas's disease in the population of rural communities at Campinas do Piauí city, State of Piauí, Brazil.The techniques of the indirect immunofluorescence reaction and enzyme-linked immunosorbent assay were used to detect reagent samples for Chagas disease and estimate its prevalence in the rural population. Blood samples were collected on filter paper through digital and venipuncture. Blood samples with reactive or indeterminate results were re-evaluated and subjected to the test by ELISA.In total, 763 blood samples were analysed from 161 residences of 18 rural communities, collected in residents aged between 2 and 92 years. In the indirect immunofluorescence reaction technique, 44 (5.8%) of the results were positive, being 40 (5.2%) confirmed by the enzyme-linked immunosorbent assay. Among the communities surveyed, we observed reactive cases in 15 of them, these cases being distributed, according to the age group, as follows: 1 case from 0 to 10 years; 13 cases from 11 to 60 years old; and 30 cases over 61 years.The results indicate that Chagas's disease remains with active transmission in the Campinas do Piaui city according to the occurrence of a case in a resident under 10 years of age. The region is endemic for Chagas's disease, as observed by the high prevalence of positive cases.Ce manuscrit visait à évaluer la séroprévalence de la maladie de Chagas dans la population des communautés rurales de la ville de Campinas do Piauí, état de Piauí, au Brésil. MÉTHODES: Les techniques de la réaction d'immunofluorescence indirecte et ELISA ont été utilisées pour détecter des échantillons réagissant pour la maladie de Chagas et estimer sa prévalence dans la population rurale. Des échantillons de sang ont été collectés sur papier filtre par ponction digitale et veineuse. Les échantillons de sang avec des résultats positifs ou indéterminés ont été réévalués et soumis au test ELISA. RÉSULTATS: Au total, 763 échantillons de sang ont été analysés dans 161 résidences de 18 communautés rurales, prélevés chez des résidents âgés de 2 à 92 ans. Dans la technique de la réaction d'immunofluorescence indirecte, 44 (5,8%) des résultats étaient positifs, dont 40 (5,2%) confirmés par le test ELISA. Parmi les communautés enquêtées, nous avons observé des cas réactifs dans 15 d'entre eux, ces cas se répartissant, selon la tranche d'âge, comme suit: 1 cas chez les 0 à 10 ans, 13 cas chez les 11 à 60 ans, 30 cas chez des plus de 61 ans.Les résultats indiquent que la maladie de Chagas maintient une transmission active dans la ville de Campinas do Piauí avec la survenue d'un cas chez un résident de moins de 10 ans. La région est endémique pour la maladie de Chagas, comme en témoigne la forte prévalence des cas positifs.

Abstract

Studies of social wasps (Vespidae: Polistinae) in Piauí State are scarce and only two have been carried out. Due to the lack of studies, we surveyed the wasp species in the Zoobotanical State Park in the urban area of Teresina, Piauí, Brazil. From December 2017 to May 2018, 10 expeditions were carried out using active collection with entomological nets and attractive traps with guava juice. A total of 282 individuals were collected distributed in six genera and 12 species. Parachartergus fraternus Gribodo, 1892 and Synoeca surinama (Linnaeus, 1767) are new records for Piauí, which now has 12 genera and 24 species registered for the state. Such data reveals the need to continue studying Polistinae in Piauí, in order to determine their real species distributions, help conserve natural areas and accurately manage these sites.

Abstract

Chagas disease (ChD), caused by the hemoflagellate protozoan Trypanosoma cruzi, is an important morbidity that affects approximately six million people in the American continent. T. cruzi parasites are mainly transmitted to human by the infected feces of blood-sucking triatomine insects. The persistent disease is endemic in many regions of South America, mostly affecting residents of rural areas. The aim of this study was to evaluate epidemiological aspects of ChD in the state of Pi-auí located in northeastern Brazil. This is an analytical cross-sectional study carried out from the collection of data of the Notifiable Diseases Information System (SINAN, in Portuguese, Sistema de Informações de Agravos de Notificação) of suspected and confirmed cases of acute ChD in the state of Piauí, in the period 2010-2019. Associations between T. cruzi positivity and the study variables were determined by the chi-square test or Fisher's exact test and were raised as prevalence ratios (PR) with 95% confidence interval. According to this survey, 517 suspected cases of acute ChD were reported in Piauí, with 70 cases (13.5%) confirmed. In 88.5% of confirmed cases, confirmation occurred by laboratory diagnosis. Most of the confirmed cases occurred in municipalities located in the semiarid region, with the municipality of São João do Piauí presenting the highest number of cases. Regarding sociodemographic data, females represent 55.7% of cases, people over 50 years of age (55.7%), being three cases in people up to 18 years of age, and less than 8 years of schooling (67.1%). 77.9% of confirmed cases had vector transmission as the probable form of infection. The data available in this study conclude that vectorial transmission of ChD in the state of Piauí remains active. This fact is corroborated by the number of notified and confirmed cases of acute ChD, requiring housing improvement programs and more effective epidemiological surveillance to control the transmission of the disease in the state.
