Chlamydophila psittaci is most commonly associated with exposure to which reservoir?

• A. Amphibians
• B. Arthropods
• C. Avians
• D. Mammalians

Answer: (C)

Chlamydophila psittaci is a bacterium that causes psittacosis in humans and is carried by birds. Birds are the natural reservoir, with infection often linked to psittacine and other avian species kept as pets or in poultry. Humans typically become infected by inhaling aerosols from dried bird droppings, secretions, or dust from these infected birds. Because the organism perpetuates in birds and human illness arises from exposure to avian sources, avians are the most common reservoir. Amphibians, arthropods, and mammals are not the usual reservoirs for this pathogen.
