Avaliação coproparasitológica de equinos atendidos no Hospital Veterinário - UFPB no período de setembro e outubro de 2018.

Abstract

Parasites in horses are diseases that can be accompanied by complications ranging from a small abdominal discomfort to colic and death. Taking into account the absence of studies concerning the prevalence of gastrointestinal parasitic diseases in the equine species in the Agreste region of Paraíba, the objective of this study was to identify the main parasites of the gastrointestinal tract of horses during the period of September and October 2018, Veterinary Hospital- UFPB. In each patient a single collection of feces was performed, directly from the rectal bulb or collected from the soil, after the emission of fresh feces. Samples were placed in flasks and immediately taken to the laboratory of preventive veterinary medicine of the UFPB, for subsequent quantitative evaluation, using the McMaster method and also coproculture for the identification of infective larvae. Among the 15 animals evaluated in this study, ten animals (66.6%) presented a positive result and five (33.3%), a negative result. Among the positive animals, egg counts also revealed that five animals (33.3%) presented parasitic load less than 350 opg, three animals (20%) had parasite load between 400-900 opg and two (13.3%) parasitic load manifested between 1000-1450 opg. In the analysis of coproculture, it was verified that ten animals (66.6%) presented L3 larvae after cultivation, whose identification was, in decreasing order, Cyathostomum sl, (10/10), Strongyloide spp. (4/10) and Strongylus edentatus (1/10). In five of these animals, the presence of two species of parasites was observed simultaneously. It is possible to conclude that it is important to periodically evaluate equines through coproparasitological examinations. For a greater efficacy of the control of parasites it may be interesting to study the region's vermintic seasonality in order to implant evermating protocols at times where there is a greater contamination of the pasture and development of infective larvae.
