Abstract

The beta-hemolysin of Streptococcus agalactiae is a major virulence factor; consequently, nonhemolytic strains rarely cause infections. We report on a case of neonatal sepsis caused by a strain displaying heterogeneous hemolysin expression. It was detected by the simultaneous isolation of hemolytic and nonhemolytic colonies from cultures of the infant's blood.

摘要

无乳链球菌的β-溶血素是一种主要的毒力因子；因此，非溶血型菌株很少引起感染。我们报告了一例由表现出溶血素表达异质性的菌株引起的新生儿败血症病例。它是通过从婴儿血液培养物中同时分离出溶血和非溶血型菌落而检测到的。
