The susceptibility of quarters preinfected either experimentally with Staphylococcus epidermidis or Staphylococcus xylosus or naturally by other coagulase-negative staphylococci was measured after challenge with two different strains of Staphylococcus aureus. The proportion of infected control quarters (95%) was raised significantly higher than that of those preinfected by the coagulase-negative staphylococci (24.5%). Differences were observed in the frequency of superinfection of the quarters according to the strain of the preinfective coagulase-negative staphylococcus, duration of preinfection and somatic cell count at the time of challenge. The protective mechanism against Staph. aureus induced by preinfection with coagulase-negative staphylococci is discussed.
在用两种不同的金黄色葡萄球菌菌株进行攻击后，测定了事先通过实验感染表皮葡萄球菌或木糖葡萄球菌或自然感染其他凝固酶阴性葡萄球菌的乳腺的易感性。受感染的对照乳腺的比例（95%）显著高于事先被凝固酶阴性葡萄球菌感染的乳腺（24.5%）。根据感染前凝固酶阴性葡萄球菌的菌株、感染前持续时间和攻击时的体细胞计数，观察到乳腺重复感染的频率存在差异。本文讨论了由凝固酶阴性葡萄球菌预感染诱导的针对金黄色葡萄球菌的保护机制。
