A new scheme for identification of coagulase-negative staphylococci was applied to 138 consecutive urinary isolates of coagulase-negative staphylococci. The most common species were Staphylococcus epidermidis (53%), S. hominis (12%), and S. haemolyticus (10%). S. saprophyticus comprised only 5%. The disk method for antibiotic susceptibility for all species grouped together disclosed resistance most commonly to penicillin (35%), tetracycline (33%), methicillin (27%), and sulfonamide (24%). This pattern was also seen specifically with S. epidermidis. Further studies are needed to determine the incidence of species-specific antibiotic resistance and species-specific infection by site. This may be of particular interest in those patients with nosocomial infections due to coagulase-negative staphylococci.
一种用于鉴定凝固酶阴性葡萄球菌的新方案被应用于138株连续分离的凝固酶阴性葡萄球菌尿液分离株。最常见的菌种是表皮葡萄球菌(53%)、人葡萄球菌(12%)和溶血葡萄球菌(10%)。腐生葡萄球菌仅占5%。将所有菌种合并在一起的抗生素敏感性纸片法显示,最常见的耐药菌是青霉素(35%)、四环素(33%)、甲氧西林(27%)和磺胺类药物(24%)。这种模式在表皮葡萄球菌中也有特别体现。需要进一步研究以确定特定菌种的抗生素耐药发生率以及按部位划分的特定菌种感染发生率。这对于那些因凝固酶阴性葡萄球菌引起医院感染的患者可能特别有意义。
