从高乳糖饮食小鼠的粪便标本中分离出12株球虫，对其进行了描述。分离物是专门厌氧，革兰氏阳性，孢子形成，不运动，球芽杆菌到杆状细胞，单个，成对，有时成链。它们与其他梭状芽孢杆菌主要在形态上不同；细胞的近球形，特别是在琼脂培养基上，是相当独特的。新菌株DNA的鸟嘌呤+胞嘧啶（G + C）含量为43 ~ 45 mol%，与C. sphenoides、C. oroticum、C. indolis、C. innocuum、C. barkeri和C. nexile等G + C含量较高的梭菌相似；C. coccoides可以通过许多生化特征和/或发酵产物与这些生物明显区分开来。球虫型菌株为CLC-1 （= ATCC[American type Culture Collection] 29236 = NCTC[National Collection of type Cultures] 11035）。
C. coccoides sp. nov. is described on the basis of 12 strains isolated from a number of fecal specimens from mice fed a high-lactose diet. The isolates are obligately anaerobic, gram-positive, sporeforming, nonmotile, coccobacillary to rod-shaped cells which occur singly, in pairs and sometimes in chains. They differ from other clostridia principally in morphology; the nearly spherical form of the cells, particularly on agar media, is rather distinctive. The guanine plus cytosine (G + C) contents of the DNA of the new strains are 43-45 mol%, values similar to those of clostridia with high G + C contents, such as C. sphenoides, C. oroticum, C. indolis, C. innocuum, C. barkeri and C. nexile; C. coccoides can be clearly differentiated from these organisms by numerous biochemical characteristics and/or fermentation products. The type strain of C. coccoides is CLC-1 (= ATCC[American Type Culture Collection] 29236 = NCTC[National Collection of Type Cultures] 11035).
