The electron microscopic appearance of the cell surface of Bacteroides strains and Klebsiella pneumoniae stained with ruthenium red or colloidal iron is described. The effect of polymyxin B (PMB) was also registered. It was found that all Bacteroides strains have a polysaccharide lined 'micro-capsule' external to the outer membrane which could aggregate and form blebs. The blebs so formed were distinct from other types of bleb formed in Klebsiella involving the outer membrane and induced by PMB. Such types of PMB alterations were not induced in Bacteroides.
描述了用钌红或胶体铁染色的拟杆菌属菌株和肺炎克雷伯菌细胞表面的电子显微镜外观。还记录了多粘菌素B（PMB）的作用。发现所有拟杆菌属菌株在外膜外部都有一个多糖内衬的“微胶囊”，它可以聚集并形成泡状突起。如此形成的泡状突起与肺炎克雷伯菌中涉及外膜并由PMB诱导形成的其他类型的泡状突起不同。在拟杆菌属中不会诱导出此类PMB改变。
