Symptoms:
Paralysis of legs and/or wings
Laboured breathing
Whistling and circling movements
Unilateral and bilateral blindness.
On postmortem examination whitish nodules in muscles of thigh, neck, kidneys, testes and in ovaries are seen.
Control Measures:
Immunisation of birds by using vaccines
Procure genetically resistant chicks
Super sanitation.
