oocyst

o·o·cyst

O0083900 (ō′ə-sĭst′)n. A thick-walled structure that contains the zygote of an apicomplexan parasite and releases the infective sporozoites.

oocyst

(ˈəʊəˌsɪst) n (Zoology) an encysted zygote of sporozoan protozoans that undergoes sporogony to produce infective sporozoites

o•o•cyst

(ˈoʊ əˌsɪst)

n. the encysted zygotic stage in the life cycle of some sporozoans. [1870–75]

Oocyst

oocyst

[′ō·ə‚sist] (invertebrate zoology) The encysted zygote of some Sporozoa.

Oocyst

one of the stages in the development of protozoans of the class Sporozoa. The oocyst forms as a result of the encyst-ment of a fertilized egg cell. It is covered with a strong protective membrane. The contents of the oocyst generally divide into several nonmotile spores (in Coccidia) or motile sporozoites (in Gregarinidia). In Hemosporidia the oocyst produces thousands of sporozoites, which subsequently leave the oocyst.

oocyst

[o´o-sist] the encysted or encapsulated ookinete in the wall of a mosquito's stomach; also, the analogous stage in the development of any sporozoon.

o·o·cyst

(ō'ō-sist), The encysted form of the fertilized macrogamete, or zygote, in coccidian Sporozoea in which sporogonic multiplication occurs; results in the formation of sporozoites, infectious agents for the next stage of the sporozoan life cycle. [G. ōon, egg, + kystis, bladder]

oocyst

Public health The infectious stage of coccidian sporozoites–eg, Cryptosporidium parvum and others, which has a protective wall that facilitates survival in water and other environments

(ō'ŏ-sist) The encysted form of the fertilized macrogamete, or zygote, in coccidian Sporozoea in which sporogonic multiplication occurs; results in the formation of sporozoites, infectious agents for the next stage of the sporozoan life cycle. [G. ōon, egg, + kystis, bladder]

oocyst

A structure that develops on the outer wall of the mosquito's stomach from the fertilized malarial parasite. The parasite divides repeatedly within the oocyst which rapidly fills up with the infective form of the parasite (SPOROZOITES) until it bursts, releasing the sporozoites into the body cavity of the mosquito to be passed on to humans.

oocyst

the cyst which contains the conjugating gametes in SPOROZOANS.

Oocyst

The egg form of the toxoplasmosis organism.Mentioned in: Toxoplasmosis
