Recent Advancements in the Study of Chlamydia Pneumoniae Developing Pneumonia and Lung Cancer in Humans

Chlamydia pneumoniae is an intracellular, obligate pathogen causing diseases in humans, including pneumonia, chronic obstructive pulmonary disease (COPD), asthma, lung cancer, and other sclerotic cardiovascular diseases. Although various links have already been established documenting the role of C. pneumoniae in causing pneumonia and lung cancer, their role as a single causal factor in lung cancer is still paradoxical. Therefore, it requires further research to better understand the association of C. pneumoniae in developing lung cancer in humans. The present review is an attempt to establish the same link in the light of recent researches done so far in the field of medical microbiology and pathology in humans.
