Flagellate: From 1 Different Sources
n. a type of *protozoan with one or more fine whiplike threads (see flagellum) projecting from its body surface, by means of which it is able to swim. Some flagellates are parasites of humans and are therefore of medical importance. See Trypanosoma; Leishmania; Giardia; Trichomonas.
An intestinal flagellate protozoan of humans. May be associated with a mild diarrhoea.... dientamoeba fragilis
An intestinal flagellate protozoa of humans and other animals causing giardiasis which mayoften present as a long-lasting, chronic malabsorptive diarrhoea. Syn. include G. intestinalis and G. lamblia.... giardia duodenalis
An intestinal tract infection caused by Giardia lamblia, a flagellate protozoa now common to much of the world. Brought in by hikers and the hoards of grazing cattle, wintering over in beavers, elk and moose, it is one of the few parasites to be encountered in the mountains and north country. It is not normally a very serious infection, but for some reason certain people experience great debility.... giardiasis
Small highly staining body at the base of the flagellum of flagellate protozoa.... kinetoplast
n. the formation and release of mature flagellated male sex cells (see microgamete) by the *microgametocytes of the malarial parasite (see Plasmodium). The process, which is completed in 10–15 minutes, occurs after the microgametocytes have been transferred from a human to the stomach of a mosquito.... exflagellation
n. a genus of spiral flagellated Gram-negative bacteria. The species H. pylori (formerly classified as Campylobacter pylori) is found in the stomach within the mucous layer. It occurs in the majority of middle-aged people and may cause gastritis. It is almost invariably present in duodenal ulceration and usually in gastric ulceration. Testing to confirm infection includes the urea breath test. Eradication of the organism (using various combinations of antibiotics and *antisecretory drugs) promotes ulcer healing. H. pylori has been implicated in some forms of stomach cancer and in coronary heart disease. The role of other Helicobacter species in the causation of disease in humans is unclear.... helicobacter
n. a genus of parasitic flagellate protozoans, several species of which cause disease in humans (see leishmaniasis). The parasite assumes a different form in each of its two hosts. In humans, especially in *kala-azar patients, it is a small rounded structure, with no flagellum, called a Leishman–Donovan body, which is found within the cells of the lymphatic system, spleen, and bone marrow. In the insect carrier it is long and flagellated.... leishmania
n. the motile flagellate male sex cell of the malarial parasite (Plasmodium) and other protozoans. The microgamete is similar to the sperm cell of animals and smaller than the female sex cell (see macrogamete).... microgamete
n. a genus of rodlike Gram-negative flagellate highly motile bacteria common in the intestines and in decaying organic material. All species can decompose urea. Some species may cause disease in humans: P. vulgaris can cause urinary tract infections.... proteus
n. a genus of parasitic flagellate protozoans that move by means of a wavy membrane, bearing a single flagellum, projecting from the body surface. T. vaginalis often infects the vagina, where it may cause severe irritation and a foul-smelling discharge (see vaginitis), and sometimes also the male *urethra; it can be transmitted during sexual intercourse. T. hominis and T. tenax live in the large intestine and mouth respectively. See also trichomoniasis.... trichomonas
