Abstract

The purpose of this survey was to describe the occurrence of bovine mastitis caused by Prototheca  zopfii in Goiás State, Brazil. Samples of milk, environment and udder were taken from a herd of 120 Holstein cows. Sabourauds dextrose agar plates were incubated under aerobic conditions at 37 °C/96 h, for microbiological analysis. Somatic cell count and milk composition were also determined. Histological sections from two udders were stained with HE and PAS. Prototheca  zopfii was identified in six cows whose milk had a watery appearance. They also showed a pronounced decrease in milk yield, fat and lactose. Pronounced infiltration of mononuclear cells, atrophy of alveoli and fibrosis were observed. The presence of this agent in other herds in the State is highly likely.
