A previously undescribed Actinomyces-like bacterium was isolated from a human dental abscess. Based on its cellular morphology and the results of biochemical testing the organism was tentatively identified as a member of the genus Actinomyces, but it did not correspond to any currently recognized species of this genus. Comparative 16S rRNA gene sequencing studies showed the bacterium represents a hitherto unknown subline within the genus Actinomyces, clustering within a group of species, which includes Actinomyces bovis, the type species of the genus. Based on biochemical and molecular phylogenetic evidence, it is proposed that the unknown organism recovered from a dental abscess be classified as a new species, Actinomyces oricola sp. nov. The type strain of Actinomyces oricola is R5292(T) (=CCUG 46090(T)=CIP 107639(T)).
从一名人类牙脓肿患者中分离出一种以前未描述过的类放线菌。根据其细胞形态和生化测试结果，该微生物初步被鉴定为放线菌属的一员，但它与该属目前已知的任何物种均不相符。16S rRNA基因序列比较研究表明，该细菌代表放线菌属内一个迄今未知的亚系，聚集在一组物种中，其中包括该属的模式种牛放线菌。基于生化和分子系统发育证据，建议将从牙脓肿中分离出的未知微生物分类为一个新物种，即口生放线菌（Actinomyces oricola sp. nov.）。口生放线菌的模式菌株为R5292(T)（=CCUG 46090(T)=CIP 107639(T)）。
