Otitis externa is frequently caused by P aeruginosa and less frequently by Candida sp, Proteus sp, S aureus, and Trichophyton sp. This is in part because many ICU patients require ventilator support to help with obstructed pathways or other conditions that prevent them from breathing on their own. Microflora are only present in URT Although many microorganisms enter URT through air during breathing, most of them are removed by mucus lining and nasal hair. Understanding that a single organism may be either normal microbiota or a pathogen encourages the microbiologist and clinician to consider other key factors when making a VAP diagnosis such as which organisms constitute normal respiratory flora and what makes some members of the respiratory microbiota more pathogenic than others.
