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 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 .
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 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 ...
an old but rapid and simple method of hemoglobin estimation in the laboratories. Presently used in some places where sophisticated optical instruments are not available Haemocytometer: a microscope associated apparatus used for manual counting of cells in body fluids like blood, etc. including for sperm count
Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids, such as blood, urine, and tissue homogenates or extracts using the tools of chemistry, microbiology, hematology, molecular pathology, and Immunohaematology.
In addition to formalin, other chemical fixatives have been used. But, with the advent of immunohistochemistry (IHC) staining and diagnostic molecular pathology testing on these specimen samples, formalin has become the standard chemical fixative in human diagnostic histopathology. Fixation times for very small specimens are shorter, and ...
The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.
