Chlamydia pneumoniae

Chlamydia pneumoniae, a member of the Chlamydiaceae family, is an obligate intracellular bacterium known for its role in causing respiratory tract infections in humans. This microorganism is distinct from other Chlamydia species, such as Chlamydia trachomatis (responsible for sexually transmitted infections) and Chlamydia psittaci (associated with psittacosis).

Respiratory infections caused by C. pneumoniae are common worldwide and typically manifest as community-acquired pneumonia or bronchitis. Transmission occurs via respiratory droplets from an infected individual, often leading to sporadic outbreaks.
