Background: The occurrence of economic losses in buffaloes may be related to reproductive problems such as chlamydiosiscaused by the bacteria Chlamydia abortus considered as a zoonotic agent; and digestive problems highlighting the infectionby Mycobacterium avium subsp. paratuberculosis (Map), responsible for paratuberculosis. There is a little information aboutthese diseases in buffaloes, therefore the aim of this study was to determine the occurrence of anti-Chlamydia abortus andanti- Mycobacterium avium subsp. paratuberculosis (Map) antibodies in water buffaloes in the state of Pernambuco, Brazil.Materials, Methods & Results: Two hundred and sixty-two bubaline sera belonging to the serum bank of the InfectiousDiseases Laboratory (LIDIC) of the Federal Rural University of Pernambuco (UFRPE) were analyzed. The samples werefrom nine properties distributed in the municipalities of Agreste and Zona da Mata of the state of Pernambuco. For thedetection of anti-Chlamydia abortus and anti-Map antibodies was used a technique of Enzyme Immunoabsorption Assay (ELISA) of the IDEXX® by following the manufacturer’s instructions. Regarding the detection of anti-Chlamydiaabortus antibodies, it was observed that 47.70% (125/262) of the samples were positive. All properties showed at least onepositive animal for the investigation of anti-Chlamydia abortus antibodies. It was also verified the occurrence of 7.25%of suspected animals for the investigation of anti-C. abortus antibodies. No positives animals were observed for Map inthe bubaline analyzed.Discussion: The occurrence of anti-C. abortus antibodies in buffaloes in the region can be explained by the fact that properties with buffalo breeding has sanitary management that allows the contact between animals, thus increasing the risk oftransmission of the agent. In addition, the variation found...(AU)
