Soroepidemiologia de babesia bovis, babesia bigemina, anaplasma marginale e diagnostico molecular do trypanosoma vivax em gado leiteiro da regional de Pedreira-MA

Abstract

This work aims to achieve the seroepidemiologic study of bovine babesiosis and anaplasmosis and diagnose the Trypanosoma vivax through parasitological and molecular examination in dairy cattle of Pedreiras basin. The detection of antibodies against Babesia bovis, Babesia bigemina and Anaplasma marginale was conducted by the method of indirect ELISA. A total of 158 blood samples were collected, this number was determined by a mathematical model. Using molecular and parasitological examination, samples of 177 animals were obtained from twenty farms divided into four municipalities that make up the regional search for trypanosomiasis. The results show that the seroprevalence of babesiosis and anaplasmosis is high in Pedreiras and whether it is an area of enzootic stability. Moreover, the trypanosomiasis showed low positivity in both the parasitological examination on the PCR. However, the technique of PCR was more sensitive than the parasitological examination. We conclude that in the study area, the hemoparasitoses directly or indirectly cause economic losses.
