title: Bacterial Pneumonia Caused byStreptococcus pyogenesInfection: A Case Report and Review of the Literature.
abstract: A 78-year-old Japanese man was admitted to our hospital because of fever lasting for 4 days. His white blood cell count and C-reactive protein level were elevated and computed tomography of the chest showed bronchopneumonia in the right upper lobe of the lung.Streptococcus pyogeneswas detected from sputum and blood culture samples on admission and administration of ampicillin/sulbactam was effective. Although our patient's clinical course was good,S. pyogenespneumonia commonly shows a high rate of fatality and septicemia, and may affect a previously healthy population. Physicians should be aware of pernicious characteristics ofS. pyogenespneumonia.
