when is pseudomonas aeruginosum identified as an infectious agent
Pseudomonas aeruginosa 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.
Skin flora Many of them are bacteria of which there are around 1000 species upon human skin from 19 phyla.[1][2] Most are found in the superficial layers of the epidermis and the upper parts of hair follicles.
