Aggregatibacter aphrophilus endocarditis: a case report.

We present a case of endocarditis with embolic stroke and digital infarction due to the recently renamed Aggregatibacter aphrophilus. The isolation and identification of this organism can be problematic but was achieved in this case using both older phenotypic and newer genotypic methods. A benign tongue lesion is suggested as the likely portal of entry for this oropharyngeal organism. The patient made a good recovery with six weeks of intravenous ceftriaxone but will need cardiac valvular surgery at some point in the future.
