The lamb rumen walls were rapidly colonized by an abundant bacterial population after birth. This colonization was examined by electron microscopy in neonatal conventional lambs. The sequence of establishment of the epimural species during the 3 weeks following birth, and the distribution of bacteria on the different sacs of the rumen, were examined by scanning electron microscopy. The population was very dense and consisted of a limited number of morphological types by 2 days after birth. Three types of rods were dominant at that time. The microflora was more complex 2 weeks later. Observations by transmission electron microscopy of desquamated epithelial cells revealed the presence of adherent bacteria that are surrounded by fibrous carbohydrate coats and sometimes partially enclosed by invaginations of the epithelial cell.
出生后，羔羊瘤胃壁迅速被大量细菌群落定殖。通过电子显微镜对新生常规羔羊的这种定殖情况进行了检查。通过扫描电子显微镜检查了出生后3周内瘤胃壁表面物种的建立顺序以及瘤胃不同囊袋中细菌的分布。出生2天后，细菌群落非常密集，由数量有限的形态类型组成。当时三种类型的杆菌占主导地位。2周后微生物群落更加复杂。通过透射电子显微镜对脱落的上皮细胞进行观察，发现存在附着的细菌，这些细菌被纤维状碳水化合物包膜包围，有时部分被上皮细胞的内陷所包裹。
