Abstract

We propose a new bacteriocin typing scheme for Streptococcus mutans (Biotype I) using nine producer strains and a numerical code with three figures. Its application in 75 unrelated S. mutans strains allowed us to type all microorganisms and to obtain a total of 15 bacteriocin types. Its epidemiological use in two family groups allowed us to obtain two bacteriocin types in each one and to show the type relations between the different family components.

摘要

我们提出了一种针对变形链球菌（生物型I）的新细菌素分型方案，使用9株产生菌和一个三位数的数字编码。将其应用于75株不相关的变形链球菌菌株，使我们能够对所有微生物进行分型，并获得总共15种细菌素类型。在两个家族群体中的流行病学应用，使我们在每个群体中获得了两种细菌素类型，并展示了不同家族成员之间的类型关系。
