It is grouped with the enterobacteriacea and is an opportunistic pathogen of humans. In humans P.vulgaris is known to cause urinary tract infections and wound infections. P.vulgaris is associated with nosocomial infection, and has the ability to degrade urea to ammonia by production of the enzyme urease.McConkey agar contains lactose, which P.vulgaris does not ferment. It ferments glucose, sucrose, galactose, glycerol occasionally maltose with gas production, but never lactose.P.vulgaris ferments liquefies gelatin, casein, and blood serum, curdling milk with acid production.n humans P.vulgaris is known to cause urinary tract infections and wound infections.
