In March of 2012 was investigated a reproductive disease outbreak in cattle herds from Paraíba State, Brazil. Were examined 32 cows and two bulls Giroland breed. The cows showed signs and symptoms of reproductive failure such as repeat breeding, granular vulvovaginitis, infertility and abortions. Vaginal and preputial mucous samples were collected for analysis by PCR and isolation. The PCR reactions for Mollicutes and Ureaplasma spp. were realized with primers MGSO and GPO3, and UGP'F and UGP'R respectively. The nested PCR assay for Ureaplasma diversum was realized with primers UD1, UD2, UD3 and UD4. For bacteriologic isolation, obtained samples were diluted up to 10-1 at 10-5, inoculated into liquid and solid "UB" medium, and incubated for up to 21 days, at 37ºC in microaerophilie jar. In the PCR reactions the frequency of Mollicutes detected in the analyzed vaginal mucous samples was 65.6, for Ureaplasma spp. was 50.0, while for U. diversum was 15.6. The frequency for isolation of Mollicutes was of 57.1 and for Ureaplasma spp. was of 28.6. In the UB agar was visualized growth of Mycoplasma spp. and Ureaplasma spp., associated in six of the samples. In the cows the presence of Mollicutes and Ureaplasma spp. was confirmed for the reproductive disease outbreak in the semiarid region of Paraiba.
