DefinitionThis section has been translated automatically.
Nematode infection by Oesphagostomum species.
PathogenThis section has been translated automatically.
- Oesphagostomum species, mainly Oesophagostomus bifurcum (nematode, nematode).
- Occurring in monkeys, ruminants and pigs. In humans, infection by 3rd larvae which penetrate the intestinal wall. Some of these larvae quickly develop into adult worms which migrate back into the intestinal lumen, sometimes encapsulating some immature worms.
- Some larvae also enter the omentum or the abdominal wall, adults produce eggs in the intestinal lumen, which are excreted, from them the infectious 3rd larvae develop in 5-7 days.
- In humans only larvae are found in the intestinal mucosa.
Occurrence/EpidemiologyThis section has been translated automatically.
Performing in Uganda and Nigeria.
