Identificação de parasitos em suídeos asselvajados no Rio Grande do Sul

Abstract

The term “wild pig” generically represents animals of the species Sus scrofa scrofa, which are kept in the wild, popularly known as “Boars”. Due to the wide distribution of wild pigs in the Brazilian territory, there is a growing demand for their population control and monitoring of their potential as source of diseases to domestic animals and humans. In this sense, the objective of this work was to determine the presence of parasites wild pigs captured in the state of Rio Grande do Sul. External inspection, necropsy and coproparasitological analyzes were carried out in 26 animals, including the analysis of feces by centrifugal-flotation, simple sedimentation and McMaster (OPG), as well as identification of endo and ectoparasites. The external inspection identified two ectoparasites (Rhipicephalus microplus and Haematopinus sp.) in 26.9% (7/26) of the captured animals. From the necropsy, two endoparasites (Strobilocerco of Taenia hydatigena and Macracanthorhynchus sp.) were identified in 19.2% (5/26) of the animals. Of the fecal samples analyzed, 57.7% (16/26) were positive in the coproparasitological analyses. The results obtained suggest that wild pigs act as reservoirs of parasites relevant to animal and human health. These findings reinforce the importance of wild pigs’ population control in the state of Rio Grande do Sul, along with their sanitary monitoring.
