Campylobacter Flashcards
identify
(?) is also recognized as a major cause of type B gastritis
H. pylori
identify
The most common cause of bacterial gastroenteritis worldwide (preparing chicken)
C. jejuni
identify
An important risk factor for gastric carcinoma resulting in H. pylori being classified as a (?)
carcinogen
identify
This causes abortion in domestic animals, such as cattle, sheep, and swine and are primarily zoonotic organisms
Campylobacters
identify
H. pylori can be presumptively identified in a gastric biopsy specimen by testing for the presence of a (?)
rapid urease reaction
identify
(?) infection can also be diagnosed by;
- fecal antigen detection,
- microscopic examination of stained gastric tissue
- and DNA amplification tests (e.g., polymerase chain reaction assay).
H. pylori
identify
- curved
- helical/spiral
- fusiform microaerophilic
- gram-negative rods (with/without periplasmic fibers)
Helicobacter
identify
(?) is strongly associated with gastric, peptic, and duodenal ulcers as well as with gastrointestinal carcinoma
H. pylori
identify
- curved
- non-spore-forming
- gram-negative
- appear as long spirals or ‘S’ or seagull-wing shapes
- “darting” motility
