metacestode

importer/temp
[:life-stage/id "WBls:0000716"] :life-stage/definition The larval stages of a tapeworm, beginning with the metamorphosis of the oncosphere and ending with the first evidence of sexuality in the adult worm. Includes the procercoid and plerocercoid stages of pseudophyllid cestodes, and the cysticercus, cysticercoid, coenurus, and hydatid stages of cyclophyllidean cestodes.

Onchocerca microfilaria (mammalian stage)

importer/temp
[:life-stage/id "WBls:0000727"] :life-stage/definition The stage that develops from the embyro and is released from the adult female worm, within the mammalian host. Microfilariae are unsheathed and are mainly found in nodules, the skin and connective tissues.

Brugia unsheathed microfilaria

importer/temp
[:life-stage/id "WBls:0000663"] :life-stage/definition In the mosquito, the microfilariae shed sheaths, penetrate the midgut, and migrate to the thoracic muscles were the microfilariae increase in size, molt, and develop into infective larvae (L1 and L3) over a span of 7-21 days.

Strongyloides free-living adult

importer/temp
[:life-stage/id "WBls:0000682"] :life-stage/definition The Strongyloides life-cycle stage in which male and female adult worms reproduce sexually and live entirely outside a host organism.

schistosomulum

importer/temp
[:life-stage/id "WBls:0000709"] :life-stage/definition A tailless cercarium of Schistosoma sp, which resides in the definitive host. After penetration and spending a few days in the skin, schistosomula migrate to the lungs and enter the systemic circulation and are carried to the mesenteric vein of the host where they mature into adult schistosomes.

2-fold embryo Ce

importer/temp
[:life-stage/id "WBls:0000019"] :life-stage/definition The C. elegans life stage spanning 460-520min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and double fold. A stage between 1.5-fold embryo and 3-fold embryo.

L4.1 larva Ce

importer/temp
[:life-stage/id "WBls:0000684"] :life-stage/definition The second sub-stage of the L4 larva. The inner cells of the vulva have finished migrating and have formed toroids, but have not fused. vulC and vulF have divided and a narrow lumen has formed. At 20 Centigrade: 35.1 hours after hatching, 1.1 hours from the L3-to-L4 molt.

1.5-fold embryo Ce

importer/temp
[:life-stage/id "WBls:0000018"] :life-stage/definition The C. elegans life stage spanning 420-460min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and fold back 50\%. A stage between comma embryo and 2-fold embryo.

obsolete nematode adult lumenal stage

importer/temp
[:life-stage/id "WBls:0000722"] :life-stage/definition OBSOLETE. An adult life-stage of a soil-transmitted nematode such as Trichuris sp. in which the anterior portion (whip-like end) is threaded into the tissue mucosa and the posterior of the male and female worms emerges free into the intestinal lumen to facilitate feeding, mating, and subsequent egg deposition.

nodular microfilaria

importer/temp
[:life-stage/id "WBls:0000667"] :life-stage/definition Microfilaria larvae found in nodules and ulcers.
