Pseudomonas aeruginosa

Pseudomonas aeruginosa are a Gram-negative, and non-fermentative bacilli that are responsible for infection in people who are immunocomprimised. A related bacteria is Acinetiobacter.
== Occurrence ==
			Found everywhere (dirt, feces, mouth, etc.). Common saprophytes (grows on, dead material). 	
== Resistance ==
		Very resistant to antibiotics and antimicrobials to the point that it will grow on antibiotic solutions. Pseudomonas and Acinetobacter are 12-15x more resistant to triclosan, and can grow in antimicrobial eye drops as well as antiseptic soaps. Pseudomonas is a superbug, and will cause an after the other bacteria have been killed by an antibiotic. Growing on top of other infections is also referred to as a super infection. 		
== Infections ==
			When the body is burned, the skin is damaged and the patient is exposed to infections, which can often lead to septicemia and death, 75% of the time. The three main post-burn infections are caused by Pseudomonas, Staphylococci, and Proteus. 14% of deaths are caused by pseudomonas. This is avoided by peeling off the infected dead skin and wrapping a patient in silver nitrate. 			
== Superficial skin infections ==			
Athlete’s foot – pseudomonas can grow even with ointment. 						
Bed sores; pseudomonas grows on top of bed sore infection. 						
Eczema; can cause a green pus with grape-like odor, also referred to as Pseudomonas pyoderma: pus growing on top of other organisms. 						
Hot tub dermatitis; hot tub opens pores in your skin, which allow pseudomonas to penetrate, creating a self-limiting rash. 			
== Genito-Urinary Tract ==
			Complicated UTI caused by instrumentation such as an urinary catheter. Usually nosocomial.
== Eye Infections ==
			Contact lenses: can drop on floor and get infection if not cleaned before placing in your eye. Pseudomonas attacks cornea of eye an leads to blindness. 
== Other Infections ==			
Nosocomial pneumonia - when intubated (respiratory aids) 			
Meningitis: operations, burns (not a major cause)			
Osteomyelitis: major cause is Staph aureus, but pseudomonas can also cause it. Often occurs after a dog bite or other trauma to the bone.
			
				Otitis Externa (ear) – most common cause of swimmer’s ear are pseudomonas and staph. They will often be found in dirtier places such as lakes or ponds. 			
== Treatment ==
		DOC for UTI: Ciprofloxacin
		DOC for other infections: Combination of Gentamycin + Ticarcillin (or Piperacillin)
		Related diseases are Bordatella pertussis and Legionella pneumophilia.
