Eleven strains of Cardiobacterium hominis, two strains of Kingella indologenes and six strains of CDC group EF-4 were characterized. Since all three taxa are oxidase-positive, fastidious gram-negative rods with relatively few positive reactions, they may be easily confused in the microbiological laboratory. Common characteristics are acid production from glucose, aerobic growth in semi-solid agar and very slow anaerobic growth. Group EF-4 is distinguished from the other two species by its capacity to produce catalase and its lack of indole production. Cardiobacterium hominis can be distinguished from Kingella indologenes by its ability to ferment mannitol and sorbitol and by differences in enzyme production. The three taxa also differ considerably with regard to morphological and cultural characteristics.
对11株人心杆菌、2株产吲哚金氏杆菌和6株CDC EF-4群菌株进行了特性鉴定。由于这三个分类单元均为氧化酶阳性、苛求革兰氏阴性杆菌且阳性反应相对较少，它们在微生物实验室中可能很容易混淆。共同特征为从葡萄糖产酸、在半固体琼脂中需氧生长以及极缓慢的厌氧生长。EF-4群与其他两个菌种的区别在于其产生过氧化氢酶的能力以及不产生吲哚。人心杆菌可通过其发酵甘露醇和山梨醇的能力以及酶产生的差异与产吲哚金氏杆菌区分开来。这三个分类单元在形态和培养特性方面也有很大差异。
