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 degrees 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.
本次调查的目的是描述在巴西戈亚斯州由威克氏原藻引起的奶牛乳腺炎的发生情况。从一个拥有120头荷斯坦奶牛的牛群中采集了牛奶、环境和乳房样本。将沙氏葡萄糖琼脂平板在37摄氏度有氧条件下培养96小时，用于微生物分析。还测定了体细胞计数和牛奶成分。对两个乳房的组织切片进行苏木精-伊红（HE）和过碘酸雪夫（PAS）染色。在6头牛奶呈水样外观的奶牛中鉴定出威克氏原藻。这些奶牛还表现出产奶量、脂肪和乳糖明显下降。观察到单核细胞明显浸润、肺泡萎缩和纤维化。该病原体极有可能在该州的其他牛群中存在。
