A total of 1,444 coagulase-negative staphylococci (CNS) isolates from bovine mastitic milk samples collected during 2003-2008 in Korea were identified to the species level. Of 14 species identified, S. simulans, S. haemolyticus, and S. sciuri accounted for over 60% of the isolates. All the CNS isolates were tested for susceptibility to eight antimicrobials commonly used in dairy cattle. With a few exceptions, similar resistance patterns were observed among the CNS species: penicillin and ampicillin showed the lowest activity while amikacin, cephalothin, and gentamycin were highly effective. About 39% (557/1,444) of the CNS isolates were pan-susceptible, while 12% (175/1,444) showed resistance to four or more antimicrobials tested.
从 2003 年至 2008 年期间采集的韩国牛乳腺炎奶样中，共分离出 1444 株凝固酶阴性葡萄球菌（CNS），并对其进行了种水平鉴定。在鉴定出的 14 个种中，S. simulans、S. haemolyticus 和 S. sciuri 占分离株的 60%以上。对所有 CNS 分离株进行了 8 种常用于奶牛的抗菌药物的药敏试验。除了少数例外，CNS 种之间观察到相似的耐药模式：青霉素和氨苄西林活性最低，而阿米卡星、头孢噻吩和庆大霉素高度有效。约 39%（557/1444）的 CNS 分离株对所有测试的抗菌药物均敏感，而 12%（175/1444）的分离株对 4 种或更多测试的抗菌药物表现出耐药性。
