When P. aeruginosa is isolated from a normally sterile site (blood, bone, deep collections), it is generally considered dangerous, and almost always requires treatment. [ citation needed ] However, P. aeruginosa is frequently isolated from nonsterile sites (mouth swabs, sputum , etc.), and, under these circumstances, it may represent colonization and not infection. The isolation of P. aeruginosa from nonsterile specimens should, therefore, be interpreted cautiously, and the advice of a microbiologist or infectious diseases physician/pharmacist should be sought prior to starting treatment. Often, no treatment is needed.

Infections in humans due to  P. aeruginosa  can be divided into opportunistic infections and those infections occurring in a healthy host.  P. aeruginosa  infections occur when the immune system is breached, either locally or systemically. Human hands infrequently are colonized with  P. aeruginosa;  however hospitalization increases the likelihood of finding the bacteria on intact skin. Therefore skin colonization can lead to bacteremia from catheter-related infection, or gastrointestinal colonization can lead to aspiration and pneumonia. Splashing of water from a contaminated sink, or droplets suctioned from a colonized endotrachial tube, can easily facilitate spread of  P. aeruginosa . In the normal host,  P. aeruginosa , in the proper setting can cause locally invasive disease. Large inocula of the bacteria can overwhelm normal defenses and lead to infection.
