Although Haemophilus influenzae is not the cause of influenza, it is still responsible for a number of different clinical diseases in humans. And since it is able to adapt to the penicillin binding protein, it has acquired a level of resistance to the different kinds of penicillin antibiotics. Haemophilus influenzae is a non-motile, Gram-negative, fastidious, non-spore forming, facultative anaerobic, rod-shaped bacterium.
Influenza is the most common respiratory virus resulting in CAP. Influenza infection also predisposes to subsequent development of bacterial CAP, referred to as post-influenza pneumonia. Hemophilus and Moraxella are common pathogens, particularly in patients with COPD or intrinsic lung disease.treptococcus pneumoniae, or Pneumococcus, continues to be responsible for 20 to 50 percent of CAP, and is the single most common pathogen causing CAP. Mycoplasma, Chlamydophila, and Legionella, collectively known as the atypical CAP pathogens, cause 20 - 30% of CAP.
