[Mitral endocarditis secondary to Streptococcus mitis bacteremic pneumonia].
Streptococcus viridans usually are an etiologic agent in odontogenic infection and endocarditis and only in some cases have been acknowledged as a respiratory pathogens. We present two cases of Streptococcus mitis bacteremic pneumonia with secondary mitral endocarditis in two patients that were been admitted by a respiratory infection (pneumonia), and later diagnosticated of mitral endocarditis. We dismiss the fisiopathogenic possibility of pneumonia with secondary pulmonary septic embolisms. With this description we help to prove the S. mitis respiratory system pathogenicity and show the known risk of endocarditis in any case of Streptococcus viridans bacteremic infection.
