- unsheathed microfilaria
importer/temp
[:life-stage/id "WBls:0000666"] :life-stage/definition A microfilaria life stage in which larvae are not sheathed by a membrane thought to be derived from the vitelline membrane.
- sheathed microfilaria
importer/temp
[:life-stage/id "WBls:0000110"] :life-stage/definition A microfilaria life stage in which larvae are surrounded by a membrane thought to be derived from the vitelline membrane, hence \"sheathed\".
- Brugia sheathed microfilaria
importer/temp
[:life-stage/id "WBls:0000077"] :life-stage/definition A Brugia microfilaria life stage in which larvae are surrounded by a membrane thought to be derived from the vitelline membrane, hence \"sheathed\".
- Brugia young adult
importer/temp
[:life-stage/id "WBls:0000100"] :life-stage/definition The animals have a significant \"prepatent\" period in the host, where they have moulted to adults but not yet started producing eggs or sperm\; this stage is usually-should be conditioned by days post infection, with day 26 to approximately day 60 being the \"young adult\" in most systems - but note that the speed of development is different in different host genotypes.
- protoscolex stage
importer/temp
[:life-stage/id "WBls:0000715"] :life-stage/definition An infective larval stage of cestodes which develops from the hydatid cyst. The stage begins when a clustering of cells emerge from the germinal layer of hydatid cysts. The buds elongate and the cells at their bases seem to diminish in number. Very early on a furrow appears in the elongated buds, delimiting anterior (scolex) and caudal (body) regions. Hooks are the first fully-differentiated structures formed at the apical region of the nascent scolex. A cone can later be seen at the center of the hooks, the body is expanded and a structured neck is evident between the scolex and the body. During protoscolex development this parasitic form remains attached to the germinative layer through a stalk. When fully differentiated, the stalk is cut off and the infective protoscolex is now free in the hydatid fluid. This stage ends when the protoscolex attaches, via the scolex, to the host intestinal tissue and begins to develop into a adult.
- sporocyst
importer/temp
[:life-stage/id "WBls:0000707"] :life-stage/definition A sac-like secondary larval stage. The miracidium transforms into a primary (mother) sporocyst\; germ cells within the primary sporocyst begin dividing to produce secondary (daughter) sporocysts, which migrate to the snail hepatopancreas\; once at the hepatopancreas, germ cells within the secondary sporocyst begin to divide again, this time producing cercariae.
- gastrulating embryo Ce
importer/temp
[:life-stage/id "WBls:0000010"] :life-stage/definition The C. elegans life stage spanning 100-290min after first cleavage at 20 Centigrade. Proliferate from 28 cells to 421 cells. Referring to the whole period of gastrulation.
- Brugia late embryo
importer/temp
[:life-stage/id "WBls:0000096"] :life-stage/definition From Lima bean to hatching.
- Onchocerca L3 larva (vector stage)
importer/temp
[:life-stage/id "WBls:0000732"] :life-stage/definition L3 larvae that develop from the L2 larvae in the arthropod vector. This stage is infectious to the mammalian host once it has migrated to the insect proboscis.
- Brugia post-infection L3
importer/temp
[:life-stage/id "WBls:0000099"] :life-stage/definition Derived from the host after reintroduction by vector feeding or manual inoculation\; these piL3 samples are often-should be conditioned by age (hours or days post-infection).
