Proteus vulgaris is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals.
Proteus are Gram-negative rod-shaped bacteria of the family Enterobacteriaceae. They are widely distributed in nature and also occur as normal intestinal flora of humans. An opportunistic pathogen, they are one of the common causes of urinary tract infections (UTIs) and are associated with infection-induced renal stones.
Feb 21, 2023 · P mirabilis causes 90% of Proteus infections and can be considered a community-acquired infection. P vulgaris and P penneri may be isolated from individuals in long-term care facilities and...
Most Proteus strains are susceptible to commonly used antibiotics, except nitrofurantoin and tetracycline. Like other members of Enterobacteriaceae, multidrug-resistant (MDR) strains of Proteus...
BACTERIOLOGY. Proteus spp. are motile, gram-negative bacilli that do not ferment lactose and are distinguished from other Enterobacteriaceae by their ability to deaminate phenylalanine and lysine.
Jan 9, 2016 · Proteus spp. bacteria present in soil or water habitats are often regarded as indicators of fecal pollution, posing a threat of poisoning when the contaminated water or seafood is consumed. The health risk may also be connected with drug-resistant strains sourcing from intestines.
Dec 1, 2020 · P. vulgaris is a rod-shaped, chemoorganotrophic, Gram-negative bacteria between 1 and 3 microns in size (2). It is motile by peritrichous flagella, and does not have capsules or spores (2). A key characteristic of genus Proteus is swarming ability, and a simple Dienes test is used to differentiate between strains (17).
