Overview
Psittacosis is caused by the organism Chlamydia psittaci. Chlamydia is understood to be a Gram-negative bacterium belonging to the genus Chlamydia or Chlamydophila in the family of Chlamydiaceae together with Parachlamydiaceae, Waddliaceae and Simkaniaceae in the order Chlamydiales, class and phylum Chlamydiae. Chlamydiales are obligate intracellular infectious agents in eukaryotic cells characterized by a unique developmental replication cycle.[1]
Causes
At least 460 species from 30 bird orders have been identified to be associated with the development of psittacosis. Bird handlers and those who keep birds as pets have a higher prevalence of the disease.
- Turkeys
- Pheasants
- Chickens,
- Ostriches and penguins.
- Migratory birds such as geese, may carry this pathogen.[2]
- Mule ducks have also been associated with human disease through heavy shedding.
Most humans are infected from birds of the order psittaciformes, which includes budgerigars, cockatiels, cockatoos, and parrots. Although the ducks are asymptomatic, each bird order tends to be infected by a predominant genotype of C. psittaci.
