Rothia dentocariosa endocarditis.

Despite its presence normally in the mouth, R dentocariosa appears rarely to cause infection outside the oral cavity. There is no doubt, however, as additional reports accumulate, that this organism should be recognized as having the ability to cause a serious illness in humans. In addition, in vivo experience seems to suggest that a penicillin regimen should remain first-line therapy for this infection, with the efficacy of other agents remaining unproved.
