N2 - The description of the new species Cardiobacterium valvarum prompted a search for additional strains of the organism. Here we report characterization of four oral Cardiobacterium strains from the Culture Collection of the University of Goteborg. The 16S rRNA gene sequences of the organisms exhibited 99.6% to 99.3% homology with Cardiobacterium valvarum. The cellular fatty acid profiles, electrophoretic patterns of whole-cell proteins, growth rate and nutritional requirement, colonial and cellular morphology, and biochemical reactions were also similar to those of C. valvarum. These results thus classify these organisms as oral strains of C. valvarum. All strains were susceptible to many antibiotics tested. The description of the species was emended. C. valvarum is a rare cause of endocarditis, and its relationship with periodontal diseases may need investigation.
