Three strains of B. thetaiotaomicron have been isolated from caeca of BALB/c-nu/+ mice of SPF. These Bacteroides are obligately anaerobic, Gram-negative, non-spore-forming and non-motil without flagella rods. A characteristic of staining is deep at ends and stainless at the medium of a rod. The isolation and identification of these strains has been reported in 1987. This paper introduced only the results of EM observations. Under the SEM, the unstained area of rods is always showing a concavity, which is just a nucleoid in sections under the TEM. Many lamellar corpuscles have been found in cell plasma. Some of them have been secreted out of the cells. The chemical properties and physiological functions of them are unknown.
从无特定病原体(SPF)的BALB/c-nu/+小鼠盲肠中分离出三株嗜内脏拟杆菌。这些拟杆菌为专性厌氧菌,革兰氏阴性,无芽孢形成,无鞭毛,呈非运动性杆状。染色特征为杆状菌两端深染,中间不着色。这些菌株的分离和鉴定已于1987年有报道。本文仅介绍电子显微镜观察结果。在扫描电子显微镜下,杆状菌的不着色区域总是呈现出凹陷,这在透射电子显微镜下的切片中正是拟核。在细胞质中发现了许多板层小体。其中一些已分泌到细胞外。它们的化学性质和生理功能尚不清楚。
