Foi utilizado o Ensaio de Imunoadsorção Enzimático indireto (ELISAi) com antígeno total contendo proteínas de superfície externa e a Reação em Cadeia da Polimerase quantitativa (PCRq), envolvendo o uso de SYBR Green com base na amplificação de um pequeno fragmento de gene do citocromo b. A prevalência de animais positivos no ELISAi para B. bovis, B. bigemina e para infecção mista foi de 24.87% (199/800), 20.75% (166/800) e 18.75% (150/800), respectivamente. Na PCRq foi detectado a presença de B. bovis em 15% (18/199) e de B. bigemina em 16% (19/199) dos animais, sendo que destes, 58% (11/19) apresentavam-se co-infectados pelos dois agentes. Os resultados mostram uma baixa prevalência de anticorpos anti-B. bovis e anti-B. bigemina em búfalos da Ilha do Marajó. Porém, observou-se que os agentes da babesiose bovina circulam em búfalos, podendo atuar como reservatório. / The aim of the study was to estimate the prevalence of Babesia bovis and Babesia bigemina in water buffaloes of the Marajó Island, State of Pará, Brazil. We used an indirect enzyme-linked immunosorbent assay (iELISA), with total antigen containing proteins outer surface, and polymerase chain reaction (qPCR), involving the use of SYBR Green based on amplification of a small fragment of the cytochrome b gene. The prevalence of positive animals in iELISA to B. bovis B. bigemina and mixed infection was 24.87% (199/800), 20.75% (166/800) and 18.75% (150/800), respectively. Using the PCR, the presence of B. bovis was detected in 15% (18/199) and B. bigemina in 16% (19/199) of animals, and of these, 58% (11/19) presented co-infected by the two agents. The results show a low prevalence of an- tibodies anti-B. bovis and anti-B. bigemina in water buffaloes from Marajó Island. However, it was observed that the agents of bovine babesiosis circulate in buffaloes, and these may act as reservoirs.
