What is Trichomoniasis
Trichomoniasis is caused by Trichomoniasis Gallinae, a single-celled, pear shaped protozoan with 4 whip-like anterior flagella. Trichomoniasis is also known as Canker. T Gallinae is a parasite of the upper digestive tract of many avian species causing accumulation of necrotic material in the mouth and oesophagus. It is characterised by raised lesions in the mouth and often infected birds may appear to have trouble closing their mouth.



How to spot it – clinical signs.

Infected birds display the signs in several ways.

They become

  •   depressed,
  •   emaciated,

They:

  •   will salivate excessively,
  •   will appear listless, ruffled and dull.

They will show

  •   repeated swallowing movements,
  •   open mouths

They will

  •   have noisy breathing
  •   have water eyes

There will be:

  •   some difficulty in closing their mouth,
  •   difficulty in eating and drinking
  •   difficulty in standing or maintaining balance
  •   diarrhoea
  •   death from starvation.

Characteristic yellowish-white nodules in the oral cavity, oesophagus and crop strongly suggests trichomoniasis. The infection is confirmed only under microscopic examination of the greenish fluids or cheesy material from the lesions.

Transmission occurs between birds very easily through oral and faecal contamination. When a bird lifts its head to swallow water from open containers, such as bird baths, droplets and oral secretions fall back into the container and contaminate the rest of the water. Therefore, the first diseased or carrier bird can contaminate the water supply, no matter how good previous hygiene has been.

Prior to ingestion the organism has the ability to live at least 5 days on some moist grains and 20 minutes to several hours in water.

In acute cases, mortality may occur quite suddenly with little indication that the bird has been infected. In other cases, it may take up to 3 weeks.
