The development of pneumonia requires that a pathogen reach the alveoli and that the host defenses are overwhelmed by microorganism microorganism virulence or by the inoculum size. The endogenous sources of microorganisms are nasal carriers, sinusitis, oropharynx, gastric, or tracheal colonization, and hematogenous spread.
