Site and clinical significance of Alloscardovia omnicolens and Bifidobacterium species isolated in the clinical laboratory.

ABSTRACT: Most of the members of the genus Bifidobacterium, including the related organism Alloscardovia omnicolens, are inhabitants of the gastrointestinal tract and oral cavity of humans and animals and have been considered nonpathogenic for humans. However, the actual site of isolation and the clinical significance of A. omnicolens and of Bifidobacterium species are unclear. This may be due in part to the difficulties in distinguishing these organisms from other genera such as Actinomyces. To determine the potential disease-causing role of these organisms, we analyzed the clinical significance of 15 A. omnicolens and Bifidobacterium isolates identified by 16S rRNA gene sequencing from a clinical laboratory. All of the organisms in this study were isolated from sterile sites or in significant numb
