What is the causative agent for Psittacosis in humans?

• A. Chlamydia trachomatis
• B. Chlamydia psittaci
• C. Chlamydia pneumoniae
• D. Mycobacterium tuberculosis

Answer: (B)

Psittacosis is an illness acquired from birds and is caused by an intracellular bacterium in the Chlamydia family that is classically linked to psittacine birds (parrots and related species). The species responsible is Chlamydia psittaci, which humans typically contract by inhaling dried secretions or feces from infected birds, leading to fever and pneumonia-like symptoms. Other organisms listed are associated with different diseases: Chlamydia trachomatis causes trachoma and urethritis, Chlamydia pneumoniae causes atypical pneumonia, and Mycobacterium tuberculosis causes tuberculosis. Therefore, the causative agent for psittacosis is Chlamydia psittaci.
