Klebsiella pneumoniae and Proteus mirabilis are examples of citrate positive organisms. Escherichia coli and Shigella dysenteriae are citrate negative.

Also know, How do you identify Proteus vulgaris? vulgaris is tested using the API 20E identification system 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

Symptoms of urethritis and cystitis may or may not be present. Defining symptoms of pyelonephritis include flank pain, nausea and vomiting, costovertebral angle tenderness, fever, and, rarely, a palpable and tender kidney. Hematuria and pyuria are frequently encountered.

What color did Proteus vulgaris turn on EMB?

Because Proteus vulgaris does not ferment lactose or produce acid, their colonies appear grey on EMB agar.

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.

What antibiotic is Proteus mirabilis resistant to?

Gustav Hauser

What antibiotic is Proteus mirabilis resistant to?

Both organisms are short rods which vary consid- erably in length. They are motile, do not produce spores, and are negative to Gram’s stain.

Is Proteus mirabilis dangerous?

Proteus is found abundantly in soil and water, and although it is part of the normal human intestinal flora (along with Klebsiella species, and Escherichia coli), it has been known to cause serious infections in humans.

Is Staphylococcus aureus citrate positive or negative?

Biochemical Test and Identification of Staphylococcus aureus
Basic Characteristics Properties (Staphylococcus aureus)

What type of flagella does Proteus vulgaris have?

Proteus Vulgaris is a rod shaped Gram-Negative chemoheterotrophic bacterium. The size of the individual cells varies from 0.4 to 0.6 micrometers by 1.2 to 2.5 micrometers. P. vulgaris possesses peritrichous flagella, making it actively motile.

Is Proteus mirabilis catalase positive or negative?

Since it belongs to the order Enterobacterales, general characters are applied on this genus. 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.

Where can Proteus vulgaris be found?

KEFLEX is indicated for the treatment of genitourinary tract infections, including acute prostatitis, caused by susceptible isolates of Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae.

How common is Proteus mirabilis UTI?

Univariate analysis revealed that bacteremic P. mirabilis UTIs are more common in patients with community-acquired infections than in those with nosocomial-acquired infections (41.9% vs. 22.4%, p = 0.011).

P mirabilis is likely to be sensitive to ampicillin; broad-spectrum penicillins (eg, ticarcillin, piperacillin); first-, second-, and third-generation cephalosporins; imipenem; and aztreonam. P vulgaris and P penneri are resistant to ampicillin and first-generation cephalosporins.

What does a positive indole test mean?

Performing a Test

Like many biochemical tests on bacteria, results of an indole test are indicated by a change in color following a reaction with an added reagent. A positive result is shown by the presence of a red or red-violet color in the surface alcohol layer of the broth. A negative result appears yellow.

Is Salmonella indole positive?

Salmonellae are facultative anaerobes and are catalase positive, oxidase negative and ferment glucose, mannitol and sorbotol to produce acid or acid and gas. As a group, Salmonella are able to ferment sucrose, but rarely adonitol and overall do not form indole.

How do you identify Proteus?

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. On the species level, indole is considered reliable, as it is positive for P. vulgaris, but negative for P.

How is Proteus mirabilis different from Proteus vulgaris?

Proteus mirabilis (indole negative) is the most frequent Proteus species associated with urinary tract infections, but indole-positive Proteus species like Pr. vulgaris, which are more often resistant to ampicillin, may also cause urinary tract infections. These species are often associated with an alkaline urine.
