Epidemiology of cattle anaplasmosis 1. prevalence of agglutinating fluorescent antibodies

, : Epidemiology of cattle anaplasmosis 1. prevalence of agglutinating fluorescent antibodies. Arquivo Brasileiro de Medicina Veterinaria e Zootecnia 36(4): 425-432

The prevalence of Anaplasma marginale in the Zona da Mata, Minas Gerais (Brazil), was determined through the Card Test (CT) and the indirect immunofluorescence technique (IFI). It was observed that 81.1 and 73.5% of the sera were positive to IFI and CT, respectively. Transmission, epidemiologic aspects and performance of the tests were discussed.
