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.
Leprosy Leprosy is spread between people and possibly from armadillos.[7] This is thought to occur through a cough or contact with fluid from the nose of an infected person.[7] Leprosy occurs more commonly among those living in poverty.[2] Contrary to popular belief, it is not highly contagious.[2] The two main types of disease are based on the number of bacteria present: paucibacillary and multibacillary.[2] The two types are differentiated by the number of poorly pigmented, numb skin patches present, with paucibacillary having five or fewer and multibacillary having more than five.[2] The diagnosis is confirmed by finding acid-fast bacilli in a biopsy of the skin or by detecting the DNA using polymerase chain reaction.[2]
