Abstract

Out of the total 68 S. aureus strains isolated and studied from pyoderma patients, 33 (48.5%) strains produced enterotoxin. Isolates from IED, impetigo and folliculitis exhibited high degree of enterotoxigenicity. SE-C and its combinations with other enterotoxins was common. 60.6% of the SE producers were found phage nontypable. Typable enterotoxigenic strains were associated with III, IV and mixed phage groups. S. aureus var. hominis and S. aureus var. bovis are the prevalent subspecies types and potent SE producers among pyogenic skin infections.

摘要

在从脓皮病患者中分离并研究的68株金黄色葡萄球菌中，33株（48.5%）产生肠毒素。从传染性脓疱病、脓疱疮和毛囊炎中分离出的菌株表现出高度的产肠毒素性。SE-C及其与其他肠毒素的组合很常见。60.6%的产肠毒素菌株被发现不可用噬菌体分型。可分型的产肠毒素菌株与III型、IV型和混合噬菌体组相关。人型金黄色葡萄球菌和牛型金黄色葡萄球菌是化脓性皮肤感染中常见的亚种类型和强效肠毒素产生菌。
