Cardiobacterium valvarum

Cardiobacterium valvarum is a newly described HACEK organism causing endocarditis.

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.
