Objective. To determine the prevalence of helminth infection in Trichomycterus nigromaculatus captured in environments defined from the physicochemistry of the Gaira River, in Minca, Sierra Nevada de Santa Marta, Colombia. Material and Methods. We collected 476 specimens of T. nigromaculatus covering both climatic periods of the area, which were dissected to analyze the visceral cavity. Isolated parasites were fixed in 10% formalin for subsequent clarification. The specimens were identified by observation of adult stages under a stereoscopic microscope after clarification. Results. Specimens were found exclusively from the genus Spirocamallanus (Nematoda), the species Spirocamallanus sp. parasitic prevalence ranged from 0% in August to 28.57% in April with an abundance of 1.09 worms/host. Environmental parameters such as dissolved oxygen (Mean:5.65 mg. L-1, Max:7.5 mg. L-1, Min:4.41 mg. L-1); pH (Mean:7.2, Max: 9.3, Min: 5.7) and conductivity (Mean:72.82 µs.cm-1, Max: 123.7 µs.cm-1, Min: 40 µs.cm-1) presented statistically significant differences, the environment is eutrophicated. Conclusions. Spirocamallanus sp. were described in the areas of presence of the parasitic association in T. nigromaculatus, which constitutes a new record for the Colombian Caribbean and an extension of the geographic distribution and host range of the nematode.

The aim of this article is to analyse the translation of cultural references of the Spanish version of Carmen Gauger of the chapters 1-11 of the German novel Er ist wieder da, written by Timur Vermes. An ad hoc methodology based on existing cultural translation strategies (Gurindapalli and Qassem 2019 and Marcelo Wirnitzer 2007), historical translation techniques (De Luxán Hernández, 2012, 2019, 2021), general translation theories (Hurtado Albir, 2001; Venuti, 1995; Newmark, 1988; Nida, 1964) and Santamaria's proposal (2000) will be applied. Through this analysis it will be concluded that culture is not a Paramenides' "being" (inalterable and eternal), yet a Heraclitus' notion (mutable) and that cultural translation tends to be intercultural, which reinforces the concepts of domextranjerización (De Luxán Hernández, 2021) and cultural identity (Fidalgo, 2019).

In this article, we intend to analyze the trajectory, contribution, results and the influence of the world-renowned historian, Carlo Ginzburg. His is a protracted investigation, which has not only influenced this area of knowledge, but also very distinct fields of the humanities, the sciences, and the arts. Carlo Ginzburg has been recognized and identified mainly due to two historiographic achievements: microhistory and The Cheese and the Worms. On the one hand, he is seen as the greatest representative of microhistory, a current of Italian origin which expanded mainly in the 1980s. On the other hand, this historian has been identified with one of his most successful works, that with the greatest impact: The Cheese and the Worms (1976). Ginzburg's book is an individual reconstruction, with the name and surnames, of an ordinary individual, who belongs to the peasantry, to a subordinate class. But Ginzburg's investigation comes to a turning point in the late in the 80s. His new books have a thin connecting thread that links very diverse issues in an imaginative way, which, when put together, show common resonances. [ABSTRACT FROM AUTHOR]

Introduction: The tomopterids are holopelagic polychaetes widely distributed in all oceans, nevertheless they have been poorly studied despite their important implications in the trophic webs, as predators of various groups of zooplankton, including eggs and fish larvae. Objective: To describe the structure of the community of these pelagic worms in an upwelling area in the Central American Pacific. Methods: The zooplankton samples were obtained during the oceanographic campaign DOMO IV organized by the Universidad Nacional Autónoma de Mexico, in July-August, 1982. The polychaetes of the Tomopteridae family were sorted out and identified providing data on their specific composition, abundance and distribution. Results: Four species of the genus Tomopteris were determined, being T. elegans and T. planktonis dominant, T. nationalis constant and T. euchaeta rare. T. nationalis, T. elegans and T. euchaeta have tropical and subtropical affinies, while T. planktonis have been considered as cosmopolitan species. T. elegans had the higher relative abundance (62%) and T. euchaeta the lower (2.5%). Conclusion: Overall, T. elegans and T. planktonis showed a notable rise in the abundance related to upwelling in the thermal dome of Costa Rica. [ABSTRACT FROM AUTHOR]

Due to the economic significance of the agave red worm Comadia redtenbacheri (Hammerschmidt) (Lepidoptera: Cossidae), and with the objective of increasing the knowledge about its reproductive biology, the morphology of the female reproductive system was studied. In general, it is similar to that of other Lepidoptera, with a few differences. The average potential fecundity was 104 oocytes per female. A small diverticulum or lobe was present in the base of the bursa copulatrix; inside the bursa, a single spermatophore was found. The spermatheca has a utriculus and a lagena. The glandular portion of the accessory glands is unusually long compared with other Lepidoptera. [ABSTRACT FROM AUTHOR]

This work deals with a common physical condition in the Mayan and Mesoamerican people: the pain caused by a worm that eats the teeth, called "the teeth worm". the idea to write this text comes from an oral recompilation, by the author, in the Tuxtlas, Veracruz, where this belief still stands. While listening to the narrator, it was inevitable not to relate it with colonial medical sources of the nineteenth century in the Mayan area that recorded this condition, and with some text of the Nahuatl zone. in this form, through historical development, we can analyze the disease caused by the teeth worm, understand the symbolic aspects that are involved in the creation and cure of this disease: specialists, deities, prayers, plants, animals and the use of sympathetic magic.

In the last years, work has focused around demonstrating the importance and incidence of organic fertilizers in the development of the cultivations, in obtaining of healthier productions starting from the improvement of the nutrients of the soil. For the statements mentioned above, it is necessary to acknowledge the factors that determine their interaction and behavior with the plants, soils and the processes mechanized in that this fertilizers are present. Actually, the humus of worm represents an organic fertilizer of a lot of interest for the advantages that it has for the nutrition of the plants, it is interesting and valuable to know its properties and in this way to facilitate the technological processes related with the manipulation, transportation and distribution in the field, as well as its interaction with the soil and the plants. Therefore, the objective of this work is the determination of some physical - mechanical, chemical and biological properties of the worm humus obtained under conditions of the dairy farm Guayabal, San José de las Lajas, La Havana, Cuba. The corresponding methodologies were necessary for the separation of samples and to make the physique-mechanical, chemical and biological analyses. The obtained properties are: angle of landslide and humidity of the humus, and belonging to the calls properties physique mechanics. The chemical properties: contents of: N, P, K, Mg, Ca, acidity (pH) and quantity of organic matter. The obtained results demonstrate that the humus of worm possesses conditions and properties that allow it to improve the structure of the soil, their interaction with plants and to define parameters of mechanized groups for their treatment and distribution.

This is the first record of an acanthocephalan cystacanth (Acanthocephala: Polymorphidae) parasitizing the crab Gecarcinus planatus collected in the Socorro island, Revillagigedo Archipelago, Mexico. The highest prevalence was found at coastal localities (60% vs. 3.5%) and was significantly higher in males than in females (50% vs. 16%). Cystacanth numbers were positively correlated to the size of parasitized crabs (r=0.614; p<0.01). Since these crabs are included in the diet of the night heron, red-tailed hawk and feral cat, it is likely that one or more of these species are the definitive host for this acanthocephalan.

A completely randomized design with a factorial arrangement was applied to 960 growing bovines in order to evaluate the effect of two stable systems (rotation areas of 12 and 14 stables) on calves and yearlings during dry and rainy seasons, as well as on some productive traits behavior (initial weight, final weight, and daily gain) and gastrointestinal and pulmonary nematodes control in animals and grasslands ("jiribilla" grass being dominant). Data were processed by a multiple classification variance analysis. Nematode main genera found in animals and grassland were Haemonchus, Oesophagostomum, Bunostomum, Trichostrongylus, and Dictyocaulus. Larval survival in grazing showed the highest values at 28 and 21 days during dry and rainy seasons, respectively, and a sudden decrease was detected from that date on. Parasitic infestation in animals and grassland was mainly influenced by management and handling system and season. The grazing system with 14 stables showed a better parasite control and productive traits behavior than the system with 12 stables. Therefore, 14 stables with a three-day occupation and resting periods should be established for growing bovine rearing. [ABSTRACT FROM AUTHOR]
