Answer

Cough, particularly cough productive of sputum, is the most consistent presenting symptom of bacterial pneumonia and may suggest a particular pathogen, as follows:

  • Streptococcus pneumoniae: Rust-colored sputum

  • Pseudomonas, Haemophilus, and pneumococcal species: May produce green sputum

  • Klebsiella species pneumonia: Red currant-jelly sputum

  • Anaerobic infections: Often produce foul-smelling or bad-tasting sputum
