Ocorrência de Sarcocystis (Apicomplexa: Sarcocystidae) em búfalos da Ilha de Marajó, Estado do Pará, Brasil.

Abstract

The protozoan Sarcocystis genus has more than 200 species parasitizing a wide variety of animais, with a strong prey-predator relationship. Farm animais are important sources of infection for definitive hosts through the consumption of their meat and offal raw or improperly processed because they had the cystic form of the parasite in their muscle cells. The buffaloes participate in the epidemiological chain of five to six species, including S. homininis which is zoonotic. In this context, this study aims to characterize the participation of marajoara buffalo herd in the epidemiological chain sarcocystosis, using as a biological indicator samples of heart and tongue collected in a state slaughterhouse located in the city of Belem, State of Pará. The samples were processed in the laboratory Animal Parasitology of the Amazon Federal Rural University - Bethlehem campus and the Federal University of Pará - Castanhal campus, using the peptide and PCR digestion technique. The infection was detected in ali heart samples and language in the peptide digestion technique and PCR was 51% and 50% of samples heart and tongue, respectively, confirming the great susceptibility of the herd marajoara buffalo, increasing the risk zoonotic of Sarcocystis spp.
