Ocorrência de anticorpos IgG anti-Trypanosoma vivax (Ziemann, 1905) em bovinos procedentes do estado de Alagoas, Brasil

Abstract

The aim of this study was to evaluate the occurrence of Immunoglobulin G antibodies anti-Trypanosoma vivax in bovine cattle from the east region of Alagoas State, Brazil, and associate serum-positive frequency with epidemiologic data. For this purpose, a questionnaire was applied during the blood sampling. A total of 199 serum samples from four cities were submitted to Indirect Immunofluorescence Test (IIFT). Data were analyzed by Pearson´s chisquare test for a 5% significance level. The results showed that 23, 6% (47/199) of the samples were serum-positives for T. vivax. The frequencies, by municipalities varied from 10.1% to 41.2%. The chi-square values revealed an association between positive frequency and semi-intensive breeding as well with herd’s purpose double. It is concluded that preventive measures should be adopted.
