Hexamitiasis is an infection of the intestinal flagellate Spironucleus – Hexamita columbae. Hexamitiasis (incorrectly also called intestinal trichomonasis) is mainly seen in spring and summer. This is the same period in which young pigeon diarrhea also occurs.

It is often very difficult to tell the difference between hexamitiasis and an Adeno-coli infection based on the symptoms alone. Both infections can occur together. That is why it is always advisable to have a vet determine which problem it is about.

Clinical symptoms

  • Vomiting and intestinal problems
  • Watery, dirty diarrhoea
  • Pigeons are drinking a lot
  • Pigeons lose their weight and are washed-out
  • Sometimes death (not often)


In case of illness:

  • 1 sachet (or measuring spoon) of Tricho Plus per 2 litres of water during 5 to 7 days.
  • Afterwards administer vitamins such as Supervit (1 sachet per 1 litres of drinking water) during 3 days.

Important tip:

The proper diagnosis of hexamitiasis can only be made by a microscopic examination of warm fresh droppings.
