Eight hundred and forty-eight strains of Staphylococcus aureus and coliforms isolated from milk samples taken from cows with clinical or subclinical mastitis were tested for their sensitivity to a range of antibiotics, comparing strains isolated in 1984, 1985, 1986 and 1987. The only increase in the proportion of resistant strains occurred with coliforms resistant to ampicillin and neomycin.
从患有临床或亚临床乳腺炎的奶牛所采集的牛奶样本中分离出848株金黄色葡萄球菌和大肠菌群，对其进行了一系列抗生素敏感性测试，并比较了1984年、1985年、1986年和1987年分离出的菌株。耐药菌株比例唯一增加的情况出现在对氨苄青霉素和新霉素耐药的大肠菌群中。
