Clinical, bacteriologic, serologic, and pathologic features of infections with atypical Taylorella equigenitalis in mares

Abstract

Atypical Taylorella sp infections should be considered as a differential diagnosis of equine infertility in US-origin mares, even those not exposed to stallions from countries where contagious equine metritis occurs. The origins and prevalence of atypical Taylorella sp infection in US horses and donkeys are undetermined.
