The Staphylococcus aureus enterotoxin gene cluster, egc, was detected in isolates from healthy individuals and in those from patients with bacteremia. The egc genes cooccur and are slightly enriched in strains from healthy carriers (present in 63.7% of carriage-associated isolates versus 52.9% of invasive isolates; P = 0.03). Multilocus sequence typing revealed that successful staphylococcal clones usually harbor the egc locus.
在来自健康个体以及菌血症患者的分离株中均检测到了金黄色葡萄球菌肠毒素基因簇(egc)。egc基因共同出现,并且在健康携带者的菌株中略有富集(在与携带相关的分离株中占63.7%,而在侵袭性分离株中占52.9%;P = 0.03)。多位点序列分型显示,成功的葡萄球菌克隆通常含有egc位点。
