When P. vulgaris is tested using the API 20E identification system [1] it produces positive results for sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity, and saccharose fermentation, and negative results for the remainder of the tests on the testing strip.
Proteus includes pathogens responsible for many human urinary tract infections. [3] P. mirabilis causes wound and urinary tract infections. Most strains of P. mirabilis are sensitive to ampicillin and cephalosporins. P. vulgaris is not sensitive to these antibiotics but ticarcillin. However, this organism is isolated less often in the ...
The Proteus penneri group of bacteria was named in 1982. It reclassified a group of strains formerly known as Proteus vulgaris biogroup 1. [6] In 1978, Brenner et al. showed through DNA hybridization studies that P. vulgaris was a heterogenous species. [7]
Drs. Eugeniusz Lazowski and his medical-school friend Stanisław Matulewicz were practicing in the small town of Rozwadów in Poland during World War II.Dr. Matulewicz realized that since Proteus vulgaris strain OX19 was used to manufacture the then-common Weil-Felix antibody-agglutination test for typhus, inoculating villagers with dead Proteus would cause a false positive result without ...
The basis of the test is the presence of antigenic cross-reactivity between Rickettsia spp. and certain serotypes of non-motile Proteus spp., a phenomenon first published by Edmund Weil and Arthur Felix in 1916. [2] Weil-Felix is a nonspecific agglutination test which detects anti-rickettsial antibodies in patient’s serum.
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group. A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours. The presence of some coliforms indicate fecal contamination.

DNA hybridization performed on P. vulgaris biogroup 3 isolates found four distinct genomospecies, designate genomospecies 3, 4, 5, and 6. These genomospecies are difficult to differentiate phenotypically; however, P. vulgaris genomospecies 3 is unique in that it is negative for Jordan's tartrate and it was thus designated as Proteus hauseri.
