Is P. vulgaris positive or negative?
Gram-negative bacteria
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).
How do you identify Proteus vulgaris?
Organisms that swarm on 5% sheep blood agar, exhibit a characteristics odor, and are oxidase negative can be presumptively identified as Proteus spp. With further testing by spot indole, the positive isolates may be presumptively reported as Proteus vulgaris and the negative ones as Proteus mirabilis.
Is P. vulgaris oxidase positive or negative?
oxidase-negative
It is oxidase-negative but catalase- and nitrate-positive. Specific tests include positive urease (which is the fundamental test to differentiate Proteus from Salmonella) and phenylalanine deaminase tests.

Is P. vulgaris Mr positive?
Lab identification According to laboratory fermentation tests, P. vulgaris ferments glucose and amygdalin, but does not ferment mannitol or lactose. P. vulgaris also tests positive for the methyl red (mixed acid fermentation) test and is also an extremely motile organism.
Why is P. vulgaris important?
P. vulgaris, previously considered biogroup 2, has been reported to cause UTIs, wound infections, burn infections, bloodstream infections, and respiratory tract infections (71, 137).
Is Proteus vulgaris Mr positive?
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.

What is the significance of Proteus vulgaris?
It is grouped with the Morganellaceae and is an opportunistic pathogen of humans. It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. P. vulgaris was one of the three species Hauser isolated from putrefied meat and identified (1885).

What disease is caused by Proteus vulgaris?
The most common clinical manifestations of Proteus infection are urinary tract infections (UTIs). In general, UTIs are more common in individuals aged 20 to 50 years and most common in women of this age group. In otherwise healthy women, Proteus accounts for 1% to 2% of all UTIs (E.

How is Proteus vulgaris treated?
For hospitalized patients, therapy consists of parenteral (or oral once the oral route is available) ceftriaxone, quinolone, gentamicin (plus ampicillin), or aztreonam until defervescence. Then, an oral quinolone, cephalosporin, or TMP/SMZ for 14 days may be added to complete treatment.
How is P. vulgaris treated?
Acute, uncomplicated pyelonephritis can be treated on an outpatient basis with fluoroquinolones, although a regimen of 7 to 14 days is recommended. An alternative to this treatment is a one-time dose of ceftriaxone or gentamycin followed by either TMP/SMZ, an oral fluoroquinolone, or cephalosporin for 7 to 14 days.
