The current taxonomy of Helicobacter bacteria is somewhat complex and incomplete, with new species currently being considered as possibly belonging to this genus. [2] [6] [7] Within the Helicobacter genus, H. heilmannii s. l. is a group of Helicobacter species that are distinguished from H. pylori by being two- to three-fold larger in size (they are 4-10 micrometers in length and 0.5-0.8 ...
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 ...
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 ...
H. pylori is able to adhere to the surface of the phagocytes and impede their action. This is responded to by the phagocyte in the generation and release of oxygen metabolites into the surrounding space. H. pylori can survive this response by the activity of catalase at its attachment to the phagocytic cell surface. Catalase decomposes hydrogen ...
The Warthin–Starry stain (WS) is a silver nitrate-based staining method (a silver stain) used in histology. It was first introduced in 1920 by American pathologists Aldred Scott Warthin (1866–1931) and Allen Chronister Starry (1890–1973), for the detection of spirochetes .
Swiss-model (stylized as SWISS-MODEL) is a structural bioinformatics web-server dedicated to homology modeling of 3D protein structures. [ 1 ] [ 2 ] As of 2024 [update] , homology modeling is the most accurate method to generate reliable three-dimensional protein structure models and is routinely used in many practical applications.
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions.

Helicobacter hepaticus is a bacterium in the Helicobacteraceae family, Campylobacterales order. [1]It has a spiral shape and bipolar, single, sheathed flagellum.The bacterium was first isolated from the livers of mice with active, chronic hepatitis.
