Presentation

History

The clinical course of C hominis endocarditis tends to be subacute. [9, 10] In a published series, the mean duration of symptoms was 169 days; however, this may reflect the difficulty in growing C hominis in older blood culture systems. In this same series, 44% of patients had a history of a dental procedure or oral infection. [11]
