Ornithosis is define as an infectious disease that affects many bird species worldwide such as parrots , macaws , cockatiels , parakeets ,pigeons , sparrows , ducks , hens , sea gulls etc & generally spread to humans from birds, specially psittacine, or parrot-like, birds. It can also be moved to other mammals. Ornithosis is also known as parrot fever , parrot disease & psittacosis . It is recognized as a zoonotic infectious disease produced by the bacterium Chlamydia psittaci.

This infectious disease ornithosis is characterized by pneumonitis and systemic symptoms (throughout the body).It is sometimes applied to infections from birds other than birds includes the parrots, macaws, and parakeets.

CausesOrnithosis is an contagious disease originated by chlamydia and can be spread from birds,animals to man. The bacterium Chlamydia psittaci are discharged in the lachrymal fluid, droppings, beak and throat mucus and the crop milk.

Sometimes transmission appears through direct or close interaction with contaminated secretions or body tissues, as in laboratory personnel who work with birds. Person-to-person transmission seldom occurs but generally results critical ornithosis.
The infected birds by ornithosis become the carriers & discharge the pathogen. The birds contract the disease by breathing in dust having the pathogen, by ingesting contaminated feed or water & by billing or feeding their young.
The infection may moved to the upper respiratory tract. Nasal catarrh appears, a milky yellow liquid may extract from the nostrils and then dry & obstruct them. The inflammation produces itching & pain , which the pigeon will try to scratch.
