Bovine babesiosis and anaplasmosis complex: diagnosis and evaluation of the risk factors from Bahia, Brazil.

摘要: Direct diagnoses were made by using - blood smears and nested PCR (nPCR) tests on 309 samples from crossbred dairy cattle in the municipality of Ibicarai, Bahia. From diagnostic smear slides, observed parasitic frequencies 31.1% for Anaplasma marginale 20.4% Babesia sp. nPCR diagnoses, they 63% A. marginale, 34% bigemina bovis. There significant differences (P <0.01) between two methods (nPCR slides). The compliance obtained kappa test was 0.41 0.48 sp., respectively. tick six farms analyzed only positive marginale. Evaluation risk factors relating to presence ticks age animals showed that there a association with frequency infected both pathogens. Therefore, under conditions studied, proved be good tool diagnosing agents bovine babesiosis anaplasmosis complex because its sensitivity specificity comparison smears. Ibicarai is an area endemic prevalence confirmed main agent disease.
