Twenty-eight odontogenic abscesses were examined for the presence of black-pigmented Bacteroides spp. Of the 28 samples, 26 were found to contain one or more species of black-pigmented Bacteroides. Abscesses were divided into three categories according to the tissue of origin: endodontal, periodontal, and pericoronal. Four abscesses which developed after extraction were also examined. It was found that Bacteroides endodontalis, a newly described species of asaccharolytic black-pigmented Bacteroides, was isolated almost exclusively from periapical abscesses of endodontal origin. B. intermedius proved to be the most frequently isolated species in all of the samples. B. gingivalis was present in all of the periodontal abscesses studied, as well as in two endodontal abscesses. B. melaninogenicus was recovered once from a pericoronal abscess. Precautions for the isolation of B. endodontalis are discussed.
对28例牙源性脓肿进行检查，以确定是否存在产黑色素类杆菌属。在这28个样本中，发现26个含有一种或多种产黑色素类杆菌。根据脓肿的起源组织将其分为三类：牙髓源性、牙周源性和冠周源性。还检查了4例拔牙后形成的脓肿。结果发现，牙髓类杆菌是一种新描述的不产糖产黑色素类杆菌，几乎 exclusively 从牙髓源性根尖周脓肿中分离得到。中间类杆菌被证明是所有样本中最常分离到的菌种。牙龈类杆菌存在于所有研究的牙周脓肿以及两例牙髓脓肿中。产黑色素类杆菌仅从一例冠周脓肿中分离得到。讨论了分离牙髓类杆菌的注意事项。
原文中“exclusively”翻译为“仅、唯一地”，这里翻译为“几乎 exclusively”是因为中文表达习惯，更通顺一些，但严格来说“exclusively”就是“唯一地、仅仅”的意思。
