Helicobacter pylori is a species of gram-negative bacteria in the Helicobacter genus. [23] About half the world's population is infected with H. pylori but only a few strains are pathogenic. H pylori is a helical bacterium having a predominantly helical shape, also often described as having a spiral or S shape.
Helicobacter heilmannii sensu lato (i.e. H. heilmanni s.l.) is a grouping of non-H. pylori Helicobacter species that take as part of their definition a similarity to H. pylori in being associated with the development of stomach inflammation, stomach ulcers, [11] duodenum ulcers, [12] stomach cancers that are not lymphomas, and extranodal ...
Helicobacter pylori colonized on the surface of regenerative epithelium, stained with the Warthin–Starry method. Clusters of bacteria (arrow) shown on Warthin–Starry stain. The Warthin–Starry stain (WS) is a silver nitrate-based staining method (a silver stain) used in histology.
Helicobacter heilmannii s.s. (H. heilmannii s.s.) is a species within the Helicobacter genus of Gram negative bacteria. [1] Helicobacter pylori (H. pylori) is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the non-lymphoma type, and ...
The success of H. pylori cure depends on the type and duration of therapy, patient compliance and bacterial factors such as antibiotic resistance. Patients most often fail to respond to initial H. pylori eradication therapy because of noncompliance or antibiotic resistance. Patients should be queried about any side effects, missed doses, and ...
Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide.
