What are the most common reservoirs for Chlamydia psittaci?

• A. Pigeons and Doves
• B. Psittacines (parrot-like birds), especially cockatiels and budgerigars
• C. Raptors
• D. Waterfowl

Answer: (B)

Chlamydia psittaci is most commonly carried by psittacine birds—parrot-like species. These birds, especially cockatiels and budgerigars, are frequent sources of human exposure because they are commonly kept as pets or kept in aviaries, and they shed the organism in respiratory secretions and feces. People can become infected by inhaling dust from dried secretions or feces from these birds, making psittacine species the typical reservoir in many psittacosis cases. Other birds like pigeons and doves, raptors, or waterfowl can harbor the organism, but they are less commonly implicated as the primary reservoir in everyday exposure settings.
