Notwithstanding morphological differences, the ultrastructure of Cowdria ruminatium cultured in vitro concurred to a large extent with that in previous in vivo studies. Two distinct forms of the organism, elementary and reticulate bodies, and a 3rd group of intermediate organisms were identified. Organisms within a particular vacuole were generally a specific form, but in cells containing many colonies different forms were present in the same colony. Most organisms were enveloped by 2 membranes and a few were surrounded by a 'capsule'. C. ruminantium multiplies mainly by binary fission, but it appears that multiplication can also take place by means of budding. The taxonomy of C. ruminantium is briefly discussed.
尽管存在形态学差异，但体外培养的反刍兽考德里氏体的超微结构在很大程度上与先前的体内研究结果一致。鉴定出该生物体的两种不同形态，即原体和网状体，以及第三组中间型生物体。特定液泡内的生物体通常为特定形态，但在含有多个菌落的细胞中，同一菌落内存在不同形态。大多数生物体被两层膜包裹，少数被“荚膜”包围。反刍兽考德里氏体主要通过二分裂繁殖，但似乎也可以通过出芽方式繁殖。文中简要讨论了反刍兽考德里氏体的分类学。
