Abstract
Production of staphylococcal alpha- or alpha-beta-toxins correlated well with production of coagulase or thermonuclease (or both) in 203 Staphylococcus aureus isolates from milk and should be reliable indicators of S. aureus in the absence of Staphylococcus intermedius. Failures to produce toxin, tube coagulase, or thermonuclease occurred in only 1 to 2% of S. aureus. Evidence of beta- or alpha-beta-toxins was not found among 321 other staphylococci isolated from milk. A few coagulase- or thermonuclease-positive isolates not producing beta- or alpha-beta-toxins were found among the Staphylococcus hyicus isolates.
摘要
在从牛奶中分离出的203株金黄色葡萄球菌中，葡萄球菌α毒素或α-β毒素的产生与凝固酶或耐热核酸酶（或两者）的产生密切相关，并且在不存在中间葡萄球菌的情况下，应该是金黄色葡萄球菌的可靠指标。仅1%至2%的金黄色葡萄球菌无法产生毒素、试管凝固酶或耐热核酸酶。在从牛奶中分离出的321株其他葡萄球菌中未发现β毒素或α-β毒素的证据。在猪葡萄球菌分离株中发现了一些凝固酶或耐热核酸酶阳性但不产生β毒素或α-β毒素的分离株。
