Chlamydia infection. Computer illustration of a cell infected with Chlamydia trachomatis bacteria. Elementary bodies (EBs, small green spheres), the non-replicating infectious form of the bacteria are seen outside the host cell. EBs infect the cell and are transformed into reticulate bodies (RB), which are replicating form. RBs are seen as a group of small red spheres near the nucleus (purple) of the cell. Chlamydia is a sexually transmitted infection that can go undetected causing infertility. It also causes the eye disease trachoma, which can lead to blindness.
