Yeast mastitis outbreak in a Brazilian dairy herd
This study aimed to describe an outbreak of bovine mastitis caused by yeast in a dairy herd located in the state of Minas Gerais, Brazil. Microbiological analysis of milk samples (106) of the infected mammary quarters of lactating cows showed that Corynebacterium bovis (43.48%) and yeasts from the genus Candida (29.35%) were the main agents isolated in the herd. C. albicans(33.34%), C. catenulate (22.23%) and C. glabrata (18.52%) were the species most commonly isolated. The high prevalence of yeast mastitis was associated with lack of training formilkers, repetitive intramammary treatment and poor teat hygiene prior to the intramammary infusion. Appropriate management measures, specific treatment with antifungal drugs and removal of chronically infected animals were effective for the control of mastitis outbreak.
