Domestic swine faeces and fresh faeces from trapped barnyard rats were heavily contaminated with Prototheca zopfii, a cause of dairy cow mastitis. When the pigs and rats were maintained on Prototheca-free diets, the transient intestinal population of P. zopfii decreased precipitously and disappeared. When combined with the information that other farm animals excrete P. zopfii, it was concluded that contaminated animal feed may be the source of large numbers of P. zopfii in the farm environment. We found P. zopfii in wet spoiled feed. Rats are logical vectors for contamination of feed.
家猪粪便以及诱捕的谷仓大鼠的新鲜粪便中被引起奶牛乳腺炎的佐普夫原藻严重污染。当猪和大鼠食用不含佐普夫原藻的饲料时，肠道中短暂存在的佐普夫原藻数量急剧下降并消失。结合其他农场动物排泄佐普夫原藻这一信息，得出结论：受污染的动物饲料可能是农场环境中大量佐普夫原藻的来源。我们在潮湿变质的饲料中发现了佐普夫原藻。大鼠是饲料污染的合理传播媒介。
