The urea breath test is used to detect Helicobacter pylori (H. pylori), a type of bacteria that may infect the stomach and is a main cause of ulcers in both the stomach and duodenum (the first part of ...

Helicobacter pylori (H. pylori) bacteria attach to the stomach’s lining. In some cases, they can cause peptic and duodenal ulcers. Natural treatments, such as honey, aloe vera, and probiotics, may ...

The most common method of measuring urease activity is to add a colorimetric assay agent for ammonia (e.g., Nessler’s reagent) to a solution of hydrolyzed urea. The absorbance of the solution at a ...

Quantifying urease activity is an important task for Microbial Induced Calcite Precipitation research. A new urease activity microplate assay using a fluorescent pH indicator is presented. The method ...
