Persistent Pathogens
"Pathogens can remain alive and active even on dry surfaces, and be picked up by hands, feet, etc. A large percentage of seemingly normal asymptomatic individuals can be carriers of pathogens. MRSA is a good example of this. Perhaps 15-30% of so-called normal individuals are carriers of MRSA; that is why the problem is so widespread."

Microbiologist
Proteus vulgaris is a rod-shaped, Gram-negative bacterium that inhabits the intestinal tracts of animals and humans and can be pathogenic. P. vulgaris forms a natural part of the intestinal flora in animals and humans, and is also found in soil and water. In people whose immune systems are suppressed it can be an opportunistic pathogen, causing urinary tract infection, pneumonia or septicemia. Unlike its relative Proteus mirabilis, P. vulgaris is not sensitive to to ampicillin and cephalosporins. Proteus vulgaris is a chemoheterotroph in the Proteobacteria group.
