When compared morphologically, the two Cardiobacterium species are indistinguishable in culture, Gram stain, and growth characteristics. Isolates of C. valvarum show optimal growth by day 3 under standard 5% CO2 incubation conditions on 5% sheep blood but scant growth on chocolate agar. Colonies are non-hemolytic to weakly a-hemolytic on sheep blood agar. 16S PCR can be used to distinguish the Cardiobacterium species.
