WebChlamydiae are known for their unique biphasic life cycle during which they alternate between two morphological forms: infectious extracellular elementary bodies (EBs) and metabolically active intracellular reticulate bodies (RBs). It is clear that multiple membranes have a key function in the chlamydial developmental cycle ( Figure 1 ). Chlamydia trachomatis is a gram-negative bacterium that can replicate only within a host cell. Over the course of the C. trachomatis life cycle, the bacteria take on two distinct forms. Elementary bodies are 200 to 400 nanometers across, and are surrounded by a rigid cell wall that allows them to survive outside of a host cell. This form can initiate a new infection if it comes into contact with a susceptible host cell. Reticulate bodies are 600 to 1500 nanometers across, and are found onl… djnceWebJan 4, 2024 · Chlamydiae are obligate intracellular organisms from bacteria that now comprise 3 species.
