Mycoplasma bovis seroprevalence in Israeli dairy herds, feedlots and imported cattle.

Abstract

A total of 2079 sera were tested between 2010 and 2011 for antibodies to Mycoplasma bovis by BIO K162 ELISA kit. At the recommended cut-off "≥+", animal seroprevalence was 89% for local cows, 94% for local beef calves and 68%, 74% and 94% for calves imported from Lithuania, Hungary and Australia, respectively, with herd/shipment-prevalence of 100% for all groups. These values changed to 30% and 59% for cows and feedlot calves, respectively, and to 31%, 38% and 77% for calves imported from Lithuania, Hungary and Australia, respectively when the cut-off was increased to "≥++". The herd prevalence, however, was still high (83-100%). ELISA values found in local dairy cows were significantly lower (p <0.001) than those in calves. Notably, 42% of Australian calves showed high "≥+++" ELISA values.
