Abstract

Five strains of gram-negative, yellow chromogenic bacilli were recovered from clinical specimens which fit the characteristics of the "lathyri-herbicola group" within the genus Erwinia. The strains were facultatively anaerobic, fermentative, anaerogenic bacilli with peritrichous flagella which grew at 37 C, reduced nitrate to nitrite, and failed to produce oxidase, pectinase, arginine dihydrolase, and decarboxylases for lysine and ornithine. Aggregations of bacteria (symplasmata) were observed in the syneresis water of slant cultures, and analogous granular aggregates and biconvex, spindle-shaped bodies developed in colonies on plate cultures. Awareness of these characteristics should result in more frequent identification of Erwinia species from human sources.

摘要

从临床标本中分离出五株革兰氏阴性、产黄色色素的杆菌,它们符合欧文氏菌属中“山黧豆-杂草杆菌群”的特征。这些菌株为兼性厌氧、发酵型、不产气杆菌,具周生鞭毛,在37℃生长,能将硝酸盐还原为亚硝酸盐,不产生氧化酶、果胶酶、精氨酸双水解酶以及赖氨酸和鸟氨酸脱羧酶。在斜面培养物的离析水中观察到细菌聚集体(共质体),在平板培养物的菌落中形成类似的颗粒状聚集体以及双凸、纺锤形物体。了解这些特征应能使从人类样本中更频繁地鉴定出欧文氏菌属菌种。
