The antibiotic susceptibility of 2297 strains of Staphylococci aureus isolated from mastitic milk has been tested. The percentage of strains of S. aureus "resistant" to penicillin was 16.5%. Approximately 97% of these strains were susceptible both to tetracyclines and sulfonamides. The frequency of "resistant" strains is in good agreement with the results from a comparable survey done ten years ago. In this investigation, however, the strains of S. aureus showed great variation in their sensitivity to penicillin according to their geographical origin. Thus, the percentage "resistant" strains within counties varied from a minimum of 9.26 to a maximum of 53.05.
对从患乳腺炎奶牛的乳汁中分离出的2297株金黄色葡萄球菌进行了抗生素敏感性测试。对青霉素“耐药”的金黄色葡萄球菌菌株比例为16.5%。这些菌株中约97%对四环素和磺胺类药物敏感。“耐药”菌株的频率与十年前进行的类似调查结果高度一致。然而，在本次调查中，金黄色葡萄球菌菌株对青霉素的敏感性根据其地理来源表现出很大差异。因此，各县内“耐药”菌株的比例从最低的9.26%到最高的53.05%不等。
