Host factors that lead to colonization and infection include the following:

  • Hospitalization (especially admission to an intensive care unit)

  • Immunocompromised states (eg, diabetes, alcoholism)

  • Antimicrobial therapy

  • Prolonged use of invasive medical devices

  • Inadequate infection control practices

  • Severe illness, including major surgery

The organism gains access to the body either by direct inoculation through breached epithelial surfaces or following aspiration of oropharyngeal organisms.
