title: Concurrent community-acquired pneumonia with Legionella pneumophila and Streptococcus pneumoniae.
abstract: Both Streptococcus pneumoniae and Legionella pneumophila are well defined causes of community-acquired pneumonia, and may be associated with substantial mortality. Optimal therapy consists of penicillin for the former organism and erythromycin for the latter. We have presented a case of pneumonia caused by simultaneous infection with both of these agents. Organisms were recovered either from blood or lung tissue. This case carries important implications for treatment of community-acquired pneumonia, and conceivably could explain some of the mortality that continues to be seen with pneumococcal pneumonia.
