| ceratopogonidae | <microbiology> A family of the order diptera. It includes the insect vector culicoides which transmits filarial parasites pathogenic to man and other primates. (12 Dec 1998) |
|---|---|
| cercaria | The free-swimming trematode larva that emerges from its host snail; it may penetrate the skin of a final host (as in Schistosoma of man), encyst on vegetation (as in Fasciola), in or on fish (as in Clonorchis), or penetrate and encyst in various arthropod hosts. Body and tail are greatly varied in form, and specialised function is adapted to the particular life cycle demands of each species. See: sporocyst, redia. Origin: G. Kerkos, tail (05 Mar 2000) |
| cerci | Plural of cercus. (05 Mar 2000) |
| cercidosome | <cell biology> Specialised organelle of trypanosomes, site of terminal oxidative metabolism. Origin: Gr. Soma = body (18 Nov 1997) |
| cerclage | Encircling with a ring, loop, wire, or ligature. Cerlage can be around bone fragments to hold them together. But it usually refers to the cervix. The word comes from the French circlage meaning an encircling. (12 Dec 1998) |
| cercocebus | <zoology> A genus of the subfamily cercopithecinae inhabiting the african forests. They are also known as mangabeys. (12 Dec 1998) |
| cercocebus atys | <zoology> A species of old world monkeys from the genera cercocebus that is important in aids research. They may be naturally or experimentally infected with the simian immunodeficiency virus. They inhabit african forests from sierra leone to the congo republic. (12 Dec 1998) |
| cercocystis | A specialised form of tapeworm cysticercoid larva that develops within the vertebrate host villus rather than in an invertebrate host; e.g., the cercocystis of Hymenolepis nana in its direct or egg-borne cycle in man. See: cysticercus, cysticercoid. Origin: G. Kerkos, tail, + kystis, bladder (05 Mar 2000) |
| cercomer | The caudal appendage of a larval cestode, the procercoid stage of pseudophyllid cestodes; it may also be found on the cysticercoid larvae of taenioid cestodes, as well as in many of the hymenolepidids (e.g., Hymenolepis nana). This appendage frequently bears the hooks originally used by the hexacanth in clawing its way into the intermediate host in which the procercoid or other larval stage develops. Origin: G. Kerkos, tail + meros, part (05 Mar 2000) |
| cercomonad | Common name for members of the genus Cercomonas. (05 Mar 2000) |
| Cercomonas | A genus of freshwater and coprophilic protozoan flagellates in which members have one anterior and one posterior flagellum. Species have been described from the intestine or faeces of man and several types of domestic livestock, but have usually proved to be other genera such as Trichomonas or Chilomastix. Origin: G. Kerkos, tail + monas (monad-), unit, monad (05 Mar 2000) |
| cercopithecidae | <zoology> The family of old world monkeys and baboons consisting of two subfamilies: cercopithecinae and colobinae. They are found in africa and part of asia. (12 Dec 1998) |
| cercopithecinae | <zoology> A subfamily of the old world monkeys, cercopithecidae. They inhabit the forests and savannas of africa. This subfamily contains the following genera: cercocebus, cercopithecus, erythrocebus, macaca, papio, and theropithecus. (12 Dec 1998) |
| Cercopithecoidea | One of the three superfamilies of the suborder Anthropoidea; includes apes, Old World monkeys, and man. Origin: G. Kerkos, tail, + pithekos, monkey (05 Mar 2000) |
| cercopithecus | <zoology> A genus of old world monkeys found in africa although some species have been introduced into the west indies. This genus is composed of at least twenty species: c. Aethiops, c. Ascanius, c. Campbelli, c. Cephus, c. Denti, c. Diana, c. Dryas, c. Erythrogaster, c. Erythrotis, c. Hamlyni, c. Lhoesti, c. Mitis, c. Mona, c. Neglectus, c. Nictitans, c. Petaurista, c. Pogonias, c. Preussi, c. Salongo, and c. Wolfi. (12 Dec 1998) |
