Electronmicrographs of sections show that the L-phases of Bacillus licheniformis var. endoparasiticus (Benedek) simulate the various types of micro-organism described by previous workers as associated with ostensibly noninfective conditions, notably cancer and arthritis; e.g., mycoplasmas, mycobacteria, corynebacteria and actinomycetes. The stages of the L-cycle, from spheroplasts through smaller and larger 'diphtheroid' bacteria to the fully reverted sporogenous bacillus, differ from one another mainly in their degree of reconstitution of the cell envelopes. Occurrence in 'diphtheroids' of nonresistant, cell-wall-deficient spore-like bodies, confirms their relationship with the true sporing bacillus stage. Large, swollen forms appear to be mother cells of minute stages.
切片的电子显微镜照片显示，地衣芽孢杆菌内寄生变种（贝内德克）的L相模拟了先前研究者描述的与表面上非感染性疾病相关的各种微生物类型，尤其是癌症和关节炎；例如，支原体、分枝杆菌、棒状杆菌和放线菌。L循环的各个阶段，从原生质球到更小和更大的“类白喉”细菌，再到完全回复的产孢杆菌，彼此之间的主要区别在于其细胞壁的重建程度。在“类白喉”细菌中出现无抗性、细胞壁缺陷的孢子样体，证实了它们与真正产孢杆菌阶段的关系。大型肿胀形态似乎是微小阶段的母细胞。
