Abstract

Sixty-nine Staphylococcus aureus strains, 39 of which produced staphylococcal enterotoxin B (SEB+) and 14 of which were associated with toxic shock (TS+), were studied using the following markers: serotyping, phage typing, antibiotyping, ribotyping, zymotyping and pulsed-field electrophoresis typing. Analysis of the results showed that the enterotoxin B producing strains were derived from at least three clones: the first two consisted of methicillin-susceptible strains, while the third included the methicillin-resistant (MRSA) strains. TS+ strains of nongenital origin appeared to be distributed between the three clones, with no specific characters.

摘要

对69株金黄色葡萄球菌进行了研究,其中39株产生葡萄球菌肠毒素B(SEB+),14株与中毒性休克有关(TS+),采用了以下分型方法:血清分型、噬菌体分型、抗生素分型、核糖体分型、酶谱分型和脉冲场凝胶电泳分型。结果分析表明,产肠毒素B的菌株至少来源于三个克隆:前两个克隆由甲氧西林敏感菌株组成,而第三个克隆包括耐甲氧西林(MRSA)菌株。非生殖器来源的TS+菌株似乎分布在这三个克隆之间,没有特定特征。
