Selected Chlamydia body-form size classes, shown as ten isolated bodies. This genus-level reconstruction has no metrological scale, is non-exhaustive and non-diagnostic, and is not a micrograph or lifecycle diagram.

Chlamydia is a genus of obligate intracellular, Gram-negative bacteria with a unique biphasic developmental cycle. The genus includes three species pathogenic to humans: Chlamydia trachomatis (STI and trachoma), C. pneumoniae (respiratory infections, atherosclerosis associations), and C. psittaci (zoonotic pneumonia).
All Chlamydia species share absolute iron dependency for intracellular replication, making the genus a central example of nutritional immunity as antimicrobial defense (Karen's Brain Primitive 4).
For species-specific biology, see Chlamydia trachomatis.

Iron dependency: The reticulate body requires host-derived iron; IFN-gamma-induced iron restriction is the primary host defense.
Pelvic inflammatory disease and tubal infertility: C. trachomatis ascending infection.
Prostatitis: C. trachomatis detected in prostatic secretions.
Endometriosis context: Chlamydia detected in vaginal/cervical microbiome of endometriosis patients.
Ovarian cancer: Part of the reproductive tract microbiome discussion in ovarian cancer oncobiosis.
