Explain how the urease test is useful for identifying members of the genus proteus?
Genus proteus is know for their fast hydrolysis of urea into ammonia. In presence of proteus the agar slant quickly turns pink (positve) while known proteus would be yellowish. The pink color is a sign of alkaline presence and the increase of pH (7-8.5) and phenol red is the pH color indicator. http://www.microbelibrary.org/Laboratory%20Diagnostics/details.asp?id=457&Lang=
Is proteus urease positive?
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.
What is a Urea Electrolyte test?
Urea clearance test. Urea is a waste product that is created by protein metabolism and excreted in the urine. The urea clearance test requires a blood sample to measure the amount of urea in the bloodstream and two urine specimens,
Urea results from the metabolism of?
carbohydrates
What is the principle of Sodium hypobromite test for urea?
sodium hypobromite reacts with urea and nitrogen gas is released as brisk effervesence
What bacteria is indole negative urea positive methyl red positive hydrogen sulfide positive and lactose negative?
urease negative

What is urease test in microbiology?
When determining the ability of a bacteria to degrade urea by means of the enzyme urease. To diagnose H. pylori and identification of the genus Proteus, Providentia, Kelbsiella, and Morganella by their fast urease activity.
Explain the function of phenol red in the urea broth medium?
phenol red act as the pH indicator. As the substrate urea is split into products, the presence of ammonia caused alkaline environment that cause the phenol red to turn to deep pink. Useful to test Proteus vulgaris.
Is proteus urease positive?
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.

What does a blood urea nitrogen test do?
The blood urea nitrogen (BUN) test measures the level of urea nitrogen in a sample of the patient's blood.
What is UREA test?
when urea is treated with sodium hypobromite it decomposes to give N2
Urea results from the metabolism of?
carbohydrates
What does U E mean in medical test?
Urea snd electrolytes test
What is BUN?
The BUN test stands for blood urea nitrogen test. It is used to measure the urea and nitrogen levels in your blood in order to detect issues with the kidneys or liver.
What are the Hemolysis test results for bacillus brevis?
Bacillus Brevis is alfa hemolytic for blood, it does not hydrolyses starch very well, nor urea and is VP negative (That means is MR positive).
