Pheno- and genotyping of Brucella abortus biovar 5 isolated from a water buffalo (Bubalus bubalis) fetus: First case reported in the Americas.

An isolate of Brucella spp. from an aborted water buffalo (Bubalus bubalis) fetus was characterized based on its pheno- and genotype. The phenotype was defined by carbon dioxide requirement, hydrogen sulfide production, sensitivity to thionin and basic fuchsin and agglutination with Brucella A and M monospecific antisera.

Detection of antibodies against Brucella abortus, Leptospira spp., and Apicomplexa protozoa in water buffaloes in the Northeast of Argentina.

Water buffalo industry has become a profitable activity worldwide, including the Northeast of Argentina (NEA). However, research on diseases affecting this species is scarce. The aim of the present study was to detect antibodies against Brucella abortus, Leptospira spp.

Improved molecular tools for detection of Babesia bigemina.

Molecular detection of Babesia bigemina involves a nested PCR protocol and reverse line blot hybridization (RLBH) assay based on the 18S gene. In this study, we report the development of molecular tools for improving B. bigemina detection in bovine blood-a one-step PCR assay based on the amplification of rap-1a paralogous and a new RLBH Babesia spp.
