[Actinobacillus actinomycetemcomitans infectious endocarditis. Apropos of 2 cases and review of the literature].

This work reports two cases of endocarditis caused by Actinobacillus actinomycetemcomitans. As noted in the medical literature, the mean clinical features are a subacute infection without know source of bacteremia, in a male patient aged 40 years or older and who is suffering from a heart disease. In our two presentations, the good response to single antibiotic treatment, although the optimal therapeutic approach is not yet defined, and the lack of embolism phenomena are of special interest. Spectrum of bacteria which can be responsible of infective endocarditis is widening rapidly; this study is an example of this trend.
