This eliminated two bacterium: Enterobacter aerogenes and Pseudomonas aeruginosa, leaving E. coli, P. vulgaris and K. pneumonia. The nitrate test was used to show if a bacterium would be able to reduce nitrate to nitrite or other nitrogenous compounds
Proteus vulgaris. The genus Proteus is classified in the enteric bacteria, together with Escherichia coli, Salmonella, Shigella, Enterobacter and Serratia.All these bacteria are small, Gram-negative rods and are facultative anaerobes: they ferment sugars in anaerobic conditions but can use a wide range of organic molecules in aerobic conditions ment of individual P. vulgaris strains to genomovars was based on the results of the ﬁve tests listed in Table 1. Table 2 lists the distribution of 43 P. vulgaris strains by DNA group and source of isolation. All 43 P. vulgaris isolates could be easily placed into one of four DNA groups on the basis of the results of the biochemical tests. This test demonstrate the presence of catalase, an enzyme that catalyses the release of oxygen from hydrogen peroxide (H 2 O 2).It is used to differentiate those bacteria that produces an enzyme catalase, such as staphylococci, from non-catalase producing bacteria such as streptococci.Normally 3% H 2 O 2 is used for the routine culture while 15% H 2 O 2 is used for detection of catalase in.
Certain strains of Proteus vulgaris (OX-19, OX-2, and OX-K) produce O antigens that are shared by some rickettsiae. These Proteus strains are used in an agglutination test (the Weil-Felix test) for serum antibodies produced against rickettsiae of the typhus and spotted fever groups. General Properties .

P. vulgaris also produced hydrogen sulfide, but did not test positive for motility because the culture's growth was restricted to the stab line. According to the literature, however, this was incorrect, as P. vulgaris was a motile species. The actual observation of PV's test tube was probably mistaken, as the growth may not have been very. In the years 1979, 1980, 1982-83, 1986-87 and 1992-93, 673 strains of P. mirabilis and 25 strains of P. vulgaris were isolated from the urinary tracts of patients at a Teaching Hospital in Brno. In 1982-83 and 1992-93, strains of P. mirabilis and P. vulgaris were isolated from the urine and faeces o It tests an organism's ability to ferment the sugar glucose as well as its ability to convert the end product of glycolysis, pyruvic acid into gaseous byproducts. This is a test commonly used when trying to identify Gram-negative enteric bacteria, all of which are glucose fermenters but only some of which produce gas P. vulgaris strains were typed and placed in to DNA groups as reported by Brenner et al. and Mohr O'Hara et al. by the following biochemical tests: esculin hydrolysis, elaboration of DNase, elaboration of corn oil lipase, and acid production from l-rhamnose and salicin. The test samples were incubated for a maximum of 72 h at 35°C, with. P. vulgaris 46 1993 Costas et al.

With further testing by spot indole, the positive isolates may be presumptively reported as Proteus vulgaris and the negative ones as Proteus mirabilis. Indole positive organisms: Most strains of E.coli, P. vulgaris, M. morganii and Providenica are indole positive. Point to remember: Indole test can also aid in species differentiation These strains were characterized by 40 biochemical tests and by susceptibility testing to 11 antibiotics. All produced ornithine decarboxylase and were susceptible to members of the penicillin-cephalosporin groups of antibiotics. These indole-positive strains are similar to indole-negative P. mirabilis and are distinctly different from P. vulgaris
Proteus vulgaris is variable, it maybe positive or negative. Results: 11-15-14 Gram - is hydrolase positive, gram + is hydrolase negative. IMViC series of tests distinguish between different enteric bacteria. Indole test for the presence of indole due to tryptophanase activity; Methyl red test for acidic intensity and p Methyl Red test. In two test tubes take freshly prepare MR-VP medium. To one of the test tube inoculate the sample microorganism, with the help of an inoculating loop. The other test tube containing the broth is used as a standard. Then keep both the tubes in incubator at 37 o C for about 24-48 hours for proper growth of organism. After. Result of the research indicated that biochemical charactersitic of P. fluorescens P60 was ability to form extracell enzymes such as amylse, protease, chitinase, cellulase, and gelatinase, to bind. Methyl Red Test Used to determine the ability of a bacteria to oxidize glucose and produce stable acid end products Methyl red is a pH indicator (red at pH less than 4.4 and yellow at a pH greater than 6) The combination medium used for this test is the MR-VP (methyl red/Voges-Proskauer) broth Acid production: positive methyl red End products. A urea test, testing for the activated enzyme urease was positive, ruling out E. coli. It was concluded that P. vulgaris was the unknown. To confirm, the bacterium was plated on a desoxycholate plate as a differential test for P. vulgaris. Confirming the results were correct, P. vulgaris grew in clear colonies, fermenting xylose but not.
P. vulgaris is also found on the surface of ripened cheese, and produces high concentrations of flavor compounds from amino acid degradation during the ripening process (13). 7. Pathology. P. vulgaris has been reported to cause urinary tract infections, wound infections, burn infections, bloodstream infections, and respiratory tract infections (1) .

P. vulgaris biogroup 1, or indole-negative P. vulgaris, was distinguished as a new species within the genus Proteus in 1982. The new species was named Proteus penneri in honor of John Penner, a Canadian microbiologist. Lab identification and differentiation. Extended biochemical tests have characterized P. penneri as being uniformly salicin. There are so many biochemical reactions for the well known causative agent of Pneumonia and Otitis media infection i.e. the Streptococcus pneumoniae but a few reactions are most commonly used and are medically important for distinguishing pathogenic strains of Streptococcus pneumoniae from other non- pathogenic strains as well as from other species of Streptococcus which are as follows Multitest mediafor rapididentification ofProteus species with notes on biochemical reactions ofstrains 439 10mm.test tubes in 2to 3 ml. amounts.

Salmonella typhimurium, Shigella dysenteriae, Proteus vulgaris, Pseudomonas aeruginosa, Alcaligenes faecalis etc are non lactose fermenters. The Voges-Proskauer (VP) test has found wide acceptance in clinical laboratories as a means of classifying strains of Enterobacteriaceae, based on acetoin production The biochemical profile is a series of blood tests used to evaluate the functional capacity of several critical organs and systems, such as the liver and kidneys. These tests can be done on an empty stomach or not, and are usually accompanied by a complete blood count (CBC) Biochemical Tests for the Identification of N. gonorrhoeae and Related Species. Traditionally, tests used to identify strains of Neisseria species were performed as individual non-commercial tests. Although these tests have, in many cases, been superseded by commercially available products, reference laboratories may use additional individual tests to identify strains of Neisseria and related. Biochemical Test of Alcaligenes faecalis subsp. faecalis. They are non-capsulated, catalase +ve, citrate +ve, flagellated, gram -ve bacteria
Indole combines with p-dimethylaminobenzaldehyde and produces a red band at the top of the medium. A negative indole test produces no color change upon the addition of Kovacs Reagent. The small amount of agar added to the medium provides a semi-solid structure allowing for the detection of bacterial motility The results of these tests on the suspected microorganism are then compared to known results for that organism to confirm its identification. Lab 7 will demonstrate that different bacteria, because of their unique enzymes, are capable of different biochemical reactions. It will also show the results of the activity of those enzymes On MacConkey agar, E. Coli colonies are brick red due to lactose fermentation. P. vulgaris colonies appear colorless as they do not ferment lactose. On TSI, E. coli gives an A/A reaction, while proteus is K/A with H2S production in the bu
