Foram utilizadas 112 amostras de muco vulvovaginal, coletados de vacas com distúrbios reprodutivos, para pesquisa de Mycoplasma e Ureaplasma. Para isolamentos, foram usados meios específicos para micoplasmas (SP-4) e para ureaplasmas. PCR genérica, PCR específica para Mycoplasma bovis e nested-PCR em tubo único para Ureaplasma diversum foram realizados com os DNAs extraídos das amostras. Mycoplasma spp. e U. diversum foram detectados em 12,5 e 25,0%, respectivamente. A PCR genérica resultou em reações positivas em 63,4% das amostras transportadas em SP-4 e em 69,6% das transportadas em meio de ureaplasma. M. bovis foi detectado, na PCR específica, em 9,8% das amostras e U. diversum, na nested-PCR, em 37,5%. Houve maior sensibilidade na metodologia da PCR quando comparada à técnica de cultivo para Mycoplasma e Ureaplasma.In the study, 112 samples of vulvovaginal mucus of cows bearing reproductive disturbance were investigated for Mycoplasma and Ureaplasma. Specific media for the culture of mycoplasmas (SP-4) and ureaplasmas were used. PCR with general primers, PCR specific for Mycoplasma bovis, and nested-PCR in a single tube for Ureaplasma diversum were performed to detect DNA of the sample. Mycoplasma spp. and U. diversum were isolated in 12.5 and 25.0%, respectively. With generic PCR, positive reaction was obtained in 63.4% of the samples transported in SP-4 and 69.6% in ureaplasma medium. M. bovis was detected in 9.8% of samples and nested-PCR in a single tube for U. diversum resulted in 35.0% of positive reaction. Results demonstrated increased sensitivity of PCR methodology compared with culture technique applied to the search of microorganisms of Mycoplasma and Ureasplasma genera.
