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
Birds are the major zoonotic reservoir. Despite its name, C. psittaci infection has been documented in 467 species from 30 bird orders, from psittaformes to ostriches to penguins have all been found to be associated with the development of psittacosis[2]. Bird handlers and those who keep birds as pets have a higher prevalence of the disease. Some of the birds listed below have been identified with psittacosis.
- Psittaformes[3]
- Budgerigars
- Cockatiels
- Cockatoos
- Parakeetsa
- Galliformes[4]
- Turkeys
- Pheasants
- Chickens
- Columbiformes[5]
- Doves
- Pigeons
- Passiformes
- Canaries
- Finches
- Anseriformes
- Ducks
- Geese
- Swans[6]
- 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.
Other animals documented with C psittaci infection include;
- Horses
- Cattle[7] and
- Koalas[8], although transmission to people is seemingly a rare occurrence from these sources.
