Four cases are described of Aerococcus viridans endocarditis with favorable outcome, focusing on the clinical picture. Extracardiac findings (e.g. neurological, renal, musculoskeletal, intra-abdominal) in infective endocarditis (IE) have been recognized more frequently in recent years, and may delay the diagnosis and have a negative influence on the prognosis. Aerococcus viridans, a very rare |
microorganism causing invasive infections, has been
associated with bacteremia, septic arthritis, and especially IE. As expected,
the strains isolated were susceptible to penicillins, trimethoprim/sulfamethoxazole,
and glycopeptides. Medical therapy was sufficient to cure IE in two patients,
while two others required surgical intervention. |
