RESUMO

Babesiosis, anaplasmosis, trypanosomosis and borreliosis are relevant diseases, potentially causing morbidity in cattle, leading to economic losses. The objective of this study was to determine, through indirect enzyme-linked immunosorbent assay (ELISA), the prevalence of Babesia bigemina, Babesia bovis, Anaplasma marginale, Trypanosoma vivax and Borrelia sp. antibodies in cattle to estabilish the risk of outbreaks. Sera samples of 246 female adult cattle from Castanhal and São Miguel do Guamá, northeastern Pará counties (areas with recorded copper and cobalt deficiency) were used. Crude antigen was used in the serologic technique to detect antibodies against B. bigemina, B. bovis, T. vivax and Borrelia sp. For the detection of A. marginale antibodies, recombinant major surface 1a protein (MSP1a) was used as antigen for indirect ELISA. The serum samples showed a prevalence of 99.2% (B. bigemina), 98.8% (B. bovis), 68.3% (A. marginale), 93.1% (T. vivax) and 54.9% (Borrelia sp). The municipalities were considered stable enzootic areas for B. bigemina, B. bovis and T. vivax, but unstable ones for A. marginale and Borrelia sp. In spite of the stability determined for some studied areas, babesiosis, anaplasmosis and trypanosomosis cases with severe clinical signs were seen on the studied region, possibly due to the mineral deficiency that decreases the immune response and immunoreativity of the animals.
