''C. pneumoniae''
== Ciclo de vida e método de infección ==
[[
''Chlamydophila pneumoniae'' is a small gram negative bacterium (0.2 to 1 [[micrometre|μm]]) that undergoes several transformations during its life cycle. It exists as an [[elementary body]] (EB) between [[Host (biology)|host]]s. The EB is not biologically active, but is resistant to [[Natural environment|environment]]al stresses and can survive outside a host for a limited time. The EB travels from an [[infection|infected]] person to the [[lung]]s of an uninfected person in small [[droplet]]s and is responsible for infection. Once in the lungs, the EB is taken up by [[cell (biology)|cell]]s in a pouch called an [[endosome]] by a process called [[phagocytosis]]. However, the EB is not destroyed by fusion with [[lysosome]]s, as is typical for phagocytosed material. Instead, it transforms into a [[reticulate body]] and begins to replicate within the endosome. The reticulate bodies must use some of the host's cellular metabolism to complete its replication. The reticulate bodies then convert back to elementary bodies and are released back into the lung, often after causing the death of the host cell. The EBs are thereafter able to infect new cells, either in the same [[organism]] or in a new host. Thus, the life cycle of ''C. pneumoniae'' is divided between the elementary body, which is able to infect new hosts but can not replicate, and the reticulate body, which replicates but is not able to cause new infection.
