Root Kustritz, DVM, PhD, DACT While there is some evidence of Mycoplasma species infection associated with vaginitis and pregnancy loss in bitches and poor semen quality in male dogs, studies have demonstrated that Mycoplasma species are as likely to be cultured in samples from healthy animals as they are to be cultured in samples from animals with reproductive tract disease.
