近年来由凝固酶阴性葡萄球菌引起的感染逐年增多,多见于医源性和特别易感的人群如新生儿,但由凝固酶阴性溶血葡萄球菌(S.hemolyticus)引起的新生儿败血症尚未见报道。本文报告3例,并应用质粒分析、药物敏感试验、噬菌体分型进行流行病学调查,现报告如下。 In recent years, the infection caused by coagulase-negative staphylococci has been increasing year by year, more common in iatrogenic and particularly susceptible populations such as newborns, but neonatal sepsis caused by coagulase-negative S. hemolyticus has not been reported . This article reports 3 cases, and the application of plasmid analysis, drug susceptibility testing, phage typing for epidemiological survey, are as follows.
