从3例成人严重局限性牙周炎患者中分离到一种新的拟杆菌属细菌，其菌群占龈下可培养植物群的50%以上。分离株为革兰氏阴性、专性厌氧短杆菌，生长需要CO2。这些菌株为七叶皂苷阳性，氧化酶和明胶酶阴性，并从各种碳水化合物（包括阿拉伯糖、木糖、棉子糖、鼠李糖和纤维二糖）中产生酸。葡萄糖的主要酸终产物是乙酸和琥珀酸。分离株均具有外膜外的额外层，以及大量纤维或毛发状网络，含有强烈染色的钌红和孔雀石绿色物质，表明是糖脂或糖脂蛋白聚合物。本文还讨论了与其它已知拟杆菌的生理和超微结构的关系，并表明这些分离物是一个新的拟杆菌种--
Strains of a newBacteroidesspecies were isolated from three cases of severe localized periodontitis in adults, in which the organism comprised greater than 50 % of the cultivable subgingival flora. The isolates were Gram‐negative, obligately anaerobic short rods, which required CO2for growth. The strains were esculin‐positive, oxidase– and gelatinase‐negative, and produced acid from a variety of carbohydrates, including arabinose, xylose, raffinose, rhamnose, and cellobiose. The major acid end–products from glucose were acetic and succinic acids. The isolates all possessed an extra‐layer external to the outer membrane, as well as an extensive fibrous or hair‐like network of intensely staining, ruthenium red, and malachite green material, indicative of a glycolipid or a glycolipoprotein polymer. The physiological and ultrastructural observations are discussed in relation to other known bacteroides and show these isolates to be representative of a newBacteroidesspecies namedBacteroides capillus.
