Sentences with word «urease»

Experimental and clinical studies have provided convincing evidence that the vast majority of Struvite stones occur following infection of the urinary tract with urease producing bacteria (especially staphylococci.)

The formation of an alkaline (pH greater that 7.0) urine from the diet, or from urease producing bacteria, will cause the struvite crystals to precipitate out of solution and begin the formation of a urolith.

Urease inhibitors may be effective in increasing fertilizer use efficiency especially where broadcast application is required, Grant (1998).

Bacteria capable of digesting urea are called «urease positive» bacteria and in most cases we are talking about Staphylococci.

[42] Children who wear diapers may experience skin irritation, commonly referred to as diaper rash, due to contact with fecal matter, as feces contains urease which catalyzes the conversion of the urea in urine to ammonia which can irritate the skin and can cause painful redness.

In a study published in the journal Science and Technology of Advanced Materials, researchers in Japan and China tested a novel urease fabrication process for coating titanium implants with bioactive CaP / gelatin composites.

Researchers in Japan and China tested a novel urease fabrication process for coating titanium implants with bioactive CaP / gelatin composites.

Researchers found a role for the bacterial enzyme urease in the development of microbial population imbalance and inflammatory bowel disease.

Future treatments that target urease could be helpful for restoring balance.

Bacterial overgrowth may cause false positive H. Pylori test results due to the change in pH from urease activity.

They are also called triple phosphate stones, infectious stones and urease stones.

Urease breaks down urinary urea into ammonium ions thereby increasing urinary pH. If the conditions are right, stones may precipitate.

These bacteria also produce urease as a by product of their metabolism.

Urinary Tract Infection (UTI)- some bacteria produce a byproduct called urease.

Once inside the bacterial cell, nickel regulates the synthesis of urease, which in turn neutralizes the acid from the stomach.

Then the researchers forced the urea - laden solution through a device they call a bioreactor, which is packed with activated charcoal that's been soaked with urease, the enzyme that breaks down urea.

This metal is a cofactor of two essential proteins, one of which is urease, an enzyme that neutralizes gastric acid.

The authors concluded that the CaP / gel / Ti implants fabricated using their urease process not only enhanced the proliferation of stem cells and differentiation of bone cells, but also the bone bonding ability of the implants.

In vitro, Pds has been shown to produce β - glucosidase, N - acetyl - β - glucosaminidase, acid and alkaline phosphatases, esterase / esterase lipase / lipase, leucine and vailine arylamidase, naphthol - AS - B1 - phophohydrolase, various proteinases (albumin / casein / gelatin), and urease, while no enzymatic activity was indicated for cystine arylamidase, α - chymotrypsin, alpha / beta galactosidase, trypsin, β - glucoronidase, α - fucosidase, and α - mannosidase [11].

Notably, some of these enzymes present in Pds (urease, proteinase (aspartyl), and superoxide dismutase) are found in other pathogenic fungi [12], [13] and are considered dual virulence factors [14].

Another potential issue is urease - splitting bacteria that can grow in the bladder and split urea molecules into nitrogen, which is ammonia - based and causes the pH to rise and remain high.

These bacteria have the ability to convert urine urea into ammonia because of a certain enzyme they contain called urease.

Certain bacteria such as Staph and Proteus produce an enzyme called urease.

Urease will increase the pH of the urine and promote ammonium in the urine.

If there is a persistent urinary tract infection we might use a urease inhibitor called acetohydroxamic acid.

Antibiotics such as neomycin (10 mg / lb by mouth every 8 to 12 hours) or metronidazole (4 mg / lb by mouth every 12 hours) are commonly used on a short - term basis to alter the urease - producing intestinal bacterial population.

Struvite crystals are not unusual in normal urine and are usually of no consequence unless they are accompanied by an infection with a bacterial species that produces an enzyme called «urease.»

A stone can form as quickly as 2 weeks after infection with a urease positive bacterium sets in.
