Trypanosoma vivax infects a wide range of wild and domestic ungulates, causing important losses for the livestock industry. The aim of the present study was to assess the detection of IgG antibodies against T. vivax in cattle from the state of Pernambuco, Brazil. Therefore, we analyzed 2.053 blood serum samples from cattle herds of municipalities in Pernambuco, what was made by Immunofluorescence Assay. The overall seroprevalence of IgG antibodies against T. vivax in cattle was 13.93% (286/2053). The frequencies, by region, varied from 11.90% to 15.99%. Thus, the data obtained allowed to characterize the state of Pernambuco as an area of enzootic instability for T. vivax. The frequency herein reported (i.e., 13.93%) indicates that Pernambuco is an endemic area for T. vivax, this parasite being spread throughout the state. |
