Mycoplasma hyorhinis has been implicated as a causative agent of polyserositis, lameness, and swollen joints.1 As reported by the herd veterinarian, gilts in two 4,000 head sow farms exhibited a substantial decrease in conception rates which coincidedwith lameness in these incoming gilts, which had not previously been described in these farms. Diagnostics in the gilts revealed M. hyorhinis. After treatment with water soluble lincomycin, gilt conception rates returned to previous levels. M. hyorhinishas been demonstrated to be highly susceptible to lincomycin.2 Reproductive failure has also been observed in intact boars exhibiting lameness. The systemic nature of M. hyorhinis and the resurgence in conception rates after treatment led to the hypothesis that M. hyorhinis may be present in reproductive organs and may have an effect on conception rates and semen quality. Mycoplasmas have been detected in the reproductive tract of human, canine, feline, equine, bovine, and caprine species.3,4 To date,M. hyorhinis has not been detected in the reproductive tract of pigs. The objective of this study was to determine if M. hyorhinis can be detected in the reproductive tract of mature gilts and intact boars.
