title: Endocarditis caused by penicillin-resistant viridans streptococci: 2 cases and controversies in therapy.
abstract: Although penicillin-resistant viridans streptococci have been isolated from samples from the mouth, blood, and wounds in increasing numbers, viridans streptococci isolated from patients with endocarditis have remained sensitive to penicillin for the past 5 decades. We report the cases of 2 patients with penicillin-resistant viridans streptococcal endocarditis, review 6 other cases from the literature, and summarize 2 studies that used an animal model of penicillin-resistant viridans streptococcal endocarditis.
