The capsules of Corynebacterium equi and Streptococcus equi were examined by electron microscopy after staining with ruthenium red. They were compared with the capsule of Klebsiella pneumoniae which had previously been examined using the same procedure (Springer & Roth, 1973). The capsule of C. equi had a laminated appearance. When S. equi was grown on solid medium, its capsule appeared as radially arranged projections capped by a thick electron dense layer. When grown in liquid medium, S. equi produced a capsule which showed as short thick projections with no layer external to them.
用钌红染色后，通过电子显微镜检查了马棒状杆菌和马链球菌的荚膜。将它们与先前使用相同程序检查过的肺炎克雷伯菌的荚膜进行了比较（施普林格和罗斯，1973年）。马棒状杆菌的荚膜呈分层外观。当马链球菌在固体培养基上生长时，其荚膜表现为径向排列的突起，顶部有一层厚的电子致密层。当在液体培养基中生长时，马链球菌产生的荚膜表现为短而粗的突起，外部没有层。
