title: Polymicrobial bacteremic pneumonia: report of three cases caused by Staphylococcus aureus and Streptococcus pneumoniae.
abstract: Three patients are reported with simultaneous bacteremia caused by Staphylococcus aureus and Streptococcus pneumoniae complicating community-acquired pneumonia. Polymicrobial bacteremia caused by pyogenic organisms has rarely been reported. Two of the patients had severe underlying hepatic disease, and the third had suffered a recent myocardial infarction. The infection ultimately proved fatal in each patient. The pathophysiologic aspects and clinical consequences of polymicrobial bacteremia arising from respiratory as well as from other sources is briefly reviewed.
