Abstract

Eleven out of 43 strains of Clostridium sordellii from clinical sources did not produce lecithinase activity and were not toxic to mice. However, these strains did belong to the C. sordellii group and could readily be differentiated from C. bifermentans and C. difficile on the basis of DNA-DNA homologies, carbohydrate fermentation patterns, enzyme activities, GLC analysis of fatty acid fermentation products and the electrophoretic analysis of whole cell protein extracts.

摘要

从临床样本中分离出的43株索氏梭菌中，有11株不产生卵磷脂酶活性，且对小鼠无毒。然而，这些菌株确实属于索氏梭菌属，并且基于DNA-DNA同源性、碳水化合物发酵模式、酶活性、脂肪酸发酵产物的气相色谱分析以及全细胞蛋白提取物的电泳分析，它们能够很容易地与双发酵梭菌和艰难梭菌区分开来。
