In Blattella germanica, the German roach or "croton bug," bacteriocytes are found in all individuals of both sexes. These bacteriocytes are scattered throughout the fat tissue and their cytoplasm is filled with microorganisms. Evidence is presented to show that the intracellular parasites are diphtheroidal bacilli. These diphtheroids are transmitted from one generation to another through the ova. By using a technic previously described, the intracellular parasites were isolated and cultivated from the adult bacteriocytes and from embryos. Two diphtheroidal strains were cultivated with approximately equal frequency. These two strains resemble one another closely enough to be considered a single species but show certain minor differences. The sizes, general morphology, and tinctorial reactions of the two cultures correspond to the intracellular parasites of Blattella germanica. They may be distinguished from the three types of Corynebacterium periplanetae variety americana, previously described. For the species here discussed the name Corynebacterium blattellae nov. sp. is proposed.
在德国蜚蠊（即德国蟑螂或“大蠊”）中，所有雌雄个体都存在细菌细胞。这些细菌细胞散布在脂肪组织中，细胞质中充满了微生物。有证据表明，这些细胞内寄生虫是白喉棒状杆菌。这些白喉棒状杆菌通过卵子从一代传递到另一代。通过使用以前描述的技术，从成年细菌细胞和胚胎中分离和培养了这些细胞内寄生虫。两种白喉棒状杆菌以大致相等的频率被培养。这两种菌株非常相似，可以被认为是同一个种，但也存在一些微小的差异。两种培养物的大小、一般形态和染色反应与德国蜚蠊的细胞内寄生虫相对应。它们可以与之前描述的三种美洲蜚蠊棒状杆菌相区别。对于这里讨论的物种，建议使用新的种名 Corynebacterium blattellae nov. sp.。
