Paramphistomum Species

  • Paramphistomomes are rare in the UK, but can cause severe losses in ruminants in the wet tropics.
  • The adult fluke is plump and cylindrical (unusual for a trematode) and attaches to the wall of the rumen without causing serious damage.
  • The eggs are like those of Fasciola, but are colourless.
  • The intermediate hosts are water snails.
  • These shed cercariae that form metacercariae on vegetation.
  • Disease occurs if metacercariae are eaten in large numbers.
  • Enteritis and diarrhoea result when immature flukes migrate along the small intestine (where the metacercariae excyst) towards the rumen.
