COSTA, Geraldo Márcio da et al. Mastitis caused by yeasts in dairy herds in the South of the Minas Gerais State, Brazil. Cienc. Rural [online]. 2008, vol.38, n.7, pp.1938-1942. ISSN 1678-4596.

The objective of this study was to report the frequency of intramammary infections by yeasts, in Minas Gerais State, from milk samples (n = 1710) collected in 40 dairy herds. Fifty six yeast strains of the genus Candida and one strain of Trichosporon loubieri were isolated. Candida albicans was the dominant species (28.1% of the strains), followed by Candida parapsilosis (19.3%), Candida catenulata (14.0%), Candida glabrata (14.0%), Candida tropicalis (8.8%). Mixed infections were detected in 29.8% of yeast-positive cows. The yeast infection was more frequent (84%) in cows with subclinical mastitis. The low rate of isolation of yeasts suggests that these microorganisms are not relevant to bovine mastitis in the studied region.

Keywords : bovine mastitis; yeast mastitis; Candida sp; Brazil.
