Educational content for breeders — not a substitute for veterinary advice. Doses and treatments here are general; actual diagnosis and treatment must be supervised by a veterinarian.

One of the most dangerous and deadly pigeon diseases. It is caused by a motile flagellate protozoan found in both wild and domestic pigeons. Parents can pass it to their squabs through crop feeding.

Symptoms

Throat swelling, yellow caseous growth in the mouth (pharyngeal form), possible difficulty swallowing/breathing.

Causes

A motile protozoan parasite (Trichomonas gallinae)

Transmission

Contaminated drinking water shared between birds, and parents feeding their squabs (crop milk).

Diagnosis

Clinical examination of the characteristic lesions in the mouth and throat; a microscopic examination of a swab from the lesion is also possible.

Treatment

Ridzol soluble powder (flock treatment in water) or Ronidazole tablets (individual); metronidazole/carnidazole as alternatives.

Prevention

Regular clean drinking water, routine flock checks, isolate symptomatic birds immediately.
