In the absence of plants, urease activity in soil is generally attributed to heterotrophic microorganisms, although it has been demonstrated that some chemoautotrophic ammonium …

Nov 29, 2025 · Urease-positive bacteria are microorganisms identified by their ability to produce the enzyme urease. This enzyme is fundamental to their survival and often acts as a …

Jun 16, 2025 · One such group is the urease-positive bacteria, defined by their ability to produce an enzyme called urease. This capability has significant implications in medicine and …

Urease test helps for the identification of Proteus species (urease positive) and to differentiate it from other non-lactose fermenting members of the Enterobacteriaceae family. Urease test is …

Any organism which can synthesise urease, will hydrolyse urea into carbon dioxide (CO 2) and ammonia (NH 3). A colour change to bright pink (fuchsia) indicates a positive result. Note: ≥ …

This enzyme aids bacterial survival and virulence, especially in the urinary tract and stomach. Common urease-positive organisms include Proteus, Klebsiella, Helicobacter pylori, …

Urea agar (Christensen’s urea agar) has a reduced buffer content and contains peptones and glucose. This medium supports the growth of many enterobacteria allowing for the observation …

Urease-positive organisms are a group of organisms that can convert urea to ammonia and carbon dioxide. This will result in increased urine pH. These organisms include Proteus, …

Urease positive strains were tested for the capacity to survive in an acid environment with or without urea (10 mM/L), at pH 7, 4, 3, and 2, respectively, at different times (0, 20, 30, and 60 …

Dec 11, 2014 · However, urease produced by the oral bacteria community has been shown to counteract caries, and caries-free subjects have high levels of urease activity in plaque …
