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.
