Abstract

Thirty-seven strains of ornithine decarboxylase-positive, nonmotile Klebsiella-Enterobacter organisms isolated from 36 patients were studied by biochemical and serological testing. Five strains gave biochemical reactions which conformed closely to those of Escherichia coli; three strains gave positive Quellung reactions to specific Klebsiella antisera. (Two of these were thought to be Enterobacter in spite of this typing reaction.) The remaining 29 strains were classified as Enterobacter. These results demonstrate the necessity of doing both an ornithine decarboxylase test and a motility test to differentiate Klebsiella from Enterobacter. Had only a motility test been done, they all would have been called Klebsiella.

摘要

对从36名患者中分离出的37株鸟氨酸脱羧酶阳性、无动力的克雷伯菌-肠杆菌属菌株进行了生化和血清学检测。5株菌株的生化反应与大肠杆菌的反应非常相似;3株菌株对特异性克雷伯菌抗血清产生了阳性荚膜肿胀反应。(尽管有这种分型反应,但其中两株被认为是肠杆菌属。)其余29株菌株被归类为肠杆菌属。这些结果表明,进行鸟氨酸脱羧酶试验和动力试验对于区分克雷伯菌和肠杆菌属是必要的。如果只进行动力试验,它们都将被称为克雷伯菌。
