what is chlamydia pneumoniae
Chlamydophila pneumoniae is a species of Chlamydophila, an obligate intracellular bacterium that infects humans and is a major cause of pneumonia. It was known as the Taiwan acute respiratory agent (TWAR) from the names of the two original isolates â Taiwan (TW-183) and an acute respiratory isolate designated AR-39.hlamydophila pneumoniae is a small gram negative bacterium (0.2 to 1 Î¼m) that undergoes several transformations during its life cycle. It exists as an elementary body (EB) between hosts. The EB is not biologically active, but is resistant to environmental stresses and can survive outside a host for a limited time.
