- L1 arrest Ce
importer/temp
[:life-stage/id "WBls:0000802"] :life-stage/definition The stage in which first stage larvae (L1) that hatch in the absence of food enter a state of developmental arrest.
- newly excysted juveniles
importer/temp
[:life-stage/id "WBls:0000718"] :life-stage/definition A Digenean (fluke) life stage that occurs in the definitive host. The stage begins when the metacercariae excyst in the intestine of the host, and continues as the NEJs migrate through the liver parenchyma where they increase in size to juvenile flukes and then to mature adults.
- Onchocerca microfilaria (vector stage)
importer/temp
[:life-stage/id "WBls:0000728"] :life-stage/definition Microfilariae that have been ingested by the vector in a blood meal from a mammalian host. Found in the midgut and muscles of the insect host.
- Platyhelminthes life stage
importer/temp
[:life-stage/id "WBls:0000704"] :life-stage/definition Any developmental stage in Platyhelminthes (flatworms).
- nodular microfilaria
importer/temp
[:life-stage/id "WBls:0000667"] :life-stage/definition Microfilaria larvae found in nodules and ulcers.
- miracidium
importer/temp
[:life-stage/id "WBls:0000706"] :life-stage/definition Free-swimming larval stage. Once the egg is released into environment, the miracidium hatches immediately and starts swimming in search of an intermediate host. In Schistosoma mansoni this is a snail of species Biomphalaria.
- 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.
- 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.
- Onchocerca L4 larva
importer/temp
[:life-stage/id "WBls:0000737"] :life-stage/definition L4 larvae that develop from L3 larvae in the mammalian host.
- Onchocerca L1 larva
importer/temp
[:life-stage/id "WBls:0000730"] :life-stage/definition L1 larvae that develop from the microfilariae in the arthropod vector.
