- Onchocerca adult male
importer/temp
[:life-stage/id "WBls:0000739"] :life-stage/definition Adult male that has developed from L4 larvae in the mammalian host.
- adult male Ce
importer/temp
[:life-stage/id "WBls:0000056"] :life-stage/definition The stage after an male animal is fully-developed and reaches maturity.
- Strongyloides free living adult male
importer/temp
[:life-stage/id "WBls:0000742"] :life-stage/definition Adult male Strongyloides living entirely outside of a host or vector organism.
- L4 larva male Ce
importer/temp
[:life-stage/id "WBls:0000073"] :life-stage/definition The fourth stage larva male. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch.
- 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.
- obsolete nematode adult intestinal stage
importer/temp
[:life-stage/id "WBls:0000721"] :life-stage/definition OBSOLETE. An adult life-stage of a soil-transmitted nematode such as Trichuris sp. that resides in the intestinal epitheium. The stage ends when the posterior of the male and female worms emerge free into the intestinal lumen at which point the worm enters the lumenal stage.
- 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.
- cercarium
importer/temp
[:life-stage/id "WBls:0000708"] :life-stage/definition An infectious life-cycle stage, which can infect by direct skin penetration (e.g. Schistosoma sp.) or ingestion (e.g. Fasciola sp.). Cercariae develop in and emerge from the intermediate invertebrate (snail) host. In Schistosoma sp., the cercarium attaches to the skin of the definitive host and secretes proteolytic enzymes helping it to enter into cutaneous capillary vessel\; upon the penetration the cercarium sheds its tail and transforms into a schistosomulum. In Fasciola sp., cercariae encyst on vegetation as dormant metacercariae until ingestion by the definitive host.
