Abstract

The work reported in this research communication investigated the occurrence of Mycoplasma bovis (M. bovis) in milk samples from cows with clinical mastitis on dairy farms from seven Brazilian states. We hypothesized that M. bovis was present in bovine clinical mastitis milk in Brazil. A total of 561 milk samples were cultured on Hayflick agar and incubated in a microaerophilic atmosphere at 5% CO2. Polymerase chain reaction (PCR) was performed for the detection of Mycoplasma spp. and Mycoplasma bovis in milk samples. Mycoplasma spp. were isolated in 2% of the milk samples, and Mycoplasma bovis was verified in 3% of the milk samples by PCR. The results showed that Mycoplasma bovis is involved in clinical mastitis in Brazilian dairy herds. We emphasize the need for further studies to investigate the infection by this agent in clinical mastitis cases, particularly in Brazil, due to the lack of knowledge about its prevalence.
