Fifteen strains of CDC group 1 coryneform and biochemically similar bacteria were isolated from clinical specimens. Of the 15 strains isolated, 11 were derived from abscesses and purulent lesions, mostly from the upper part of the body, and 3 were grown from blood cultures. Nine strains were associated with mixed anaerobic but no other aerobic flora. Seven strains exhibited the classical biochemical profile of CDC coryneform group 1; however, eight strains were unable to reduce nitrate and were called "group 1-like." Other reactions to differentiate CDC group 1 and group 1-like coryneform rods include alpha-hemolysis on human blood agar, fermentation of adonitol, and the presence of alkaline phosphatase. Fifteen strains showed marked CAMP reactions on different erythrocyte agars. Gas-liquid chromatography of volatile and nonvolatile fatty acids as well as cellular fatty acid patterns and the composition of cell wall components suggest that CDC group 1 and group 1-like coryneform bacteria do not belong to the genus Corynebacterium but possibly to the genus Actinomyces or Arcanobacterium. DNA-DNA hybridization studies revealed that group 1 and group 1-like strains represent different species.
从临床标本中分离出15株CDC 1群棒状杆菌及生化特性相似的细菌。在分离出的15株菌株中，11株来自脓肿和脓性病变，大多来自身体上部，3株由血培养生长而来。9株与混合厌氧菌相关，但无其他需氧菌。7株表现出CDC 1群棒状杆菌的典型生化特征；然而，8株不能还原硝酸盐，被称为“类1群”。区分CDC 1群和类1群棒状杆菌的其他反应包括在人血琼脂上的α溶血、阿东醇发酵以及碱性磷酸酶的存在。15株在不同红细胞琼脂上显示出明显的CAMP反应。挥发性和非挥发性脂肪酸的气-液色谱分析以及细胞脂肪酸模式和细胞壁成分组成表明，CDC 1群和类1群棒状杆菌不属于棒状杆菌属，而可能属于放线菌属或隐秘杆菌属。DNA-DNA杂交研究表明，1群和类1群菌株代表不同的物种。
