Phenotypic and molecular characterization of Solobacterium moorei isolates from patients with wound infection.

Though seldom reported, Solobacterium moorei, which was first described in 2000, has been identified in specimens from patients with root canals, periradicular lesions, periodontal disease, dentoalveolar abscesses, bacteremia, septic thrombophlebitis, and halitosis. In the present study, we describe 9 cases of mixed wound infection, from a pool of 400 surgical wound infections that we have studied, in which S. moorei was isolated or found in a clone library. All isolates of S. moorei were identified by 16S rRNA gene sequence analysis, and then six were examined for their physiological and biochemical characteristics and for antimicrobial susceptibility. The results of the present study indicate that Solobacterium moorei may be a significant component in some mixed surgical wound infections and that surgical management and antimicrobial therapy may be indicated when these bacteria are identified in significant situations.
