Staphylococcal isolates from teat canal keratin and mammary secretion samples of unbred and primigravid Jersey heifers were tested in vitro for susceptibility to 12 antimicrobial agents. More than 92% of the 311 isolates were susceptible to all antimicrobial agents tested. Staphylococci other than Staphylococcus aureus demonstrated an overall susceptibility of 98.3% to all antibiotics, and Staphylococcus aureus demonstrated a 97% susceptibility. Across all staphylococcal species, susceptibility of isolates from secretion samples was 98.1%, and susceptibility of isolates from teat canal keratin samples was 93.1%. Differences in susceptibilities were observed among herds.
对未孕和初产泽西小母牛的乳头管角质层和乳汁分泌样本中的葡萄球菌分离株进行了体外测试，以检测它们对12种抗菌剂的敏感性。在311株分离株中，超过92%对所有测试的抗菌剂敏感。除金黄色葡萄球菌外的葡萄球菌对所有抗生素的总体敏感性为98.3%，金黄色葡萄球菌的敏感性为97%。在所有葡萄球菌种类中，分泌样本分离株的敏感性为98.1%，乳头管角质层样本分离株的敏感性为93.1%。不同牛群之间观察到了敏感性差异。
