Atypical community-acquired pneumonia: concurrent infection with Chlamydia psittaci and Mycobacterium tuberculosis

We have presented a case of combined pulmonary infection with Chlamydia psittaci and Mycobacterium tuberculosis, both documented by culture of lymph nodes and respiratory secretions. We describe it not only as an unusual occurrence, but also to illustrate the importance of a systematic and thorough diagnostic approach to every case of pneumonia.
