Chlamydia pathogens are immortal bacteria which attack and invade host cells, and live and replicate inside the cell. Chlamydia pathogens cannot make their own energy, and survive by consuming the energy made by the cell. When the energy in the cell is depleted, the pathogen consumes sugar, causing fermentation and an environment for fungus to develop and thrive. Chlamydia damages oxygen transport into the cell, destroys normal apoptosis, generates formation of new blood vessels, and creates an infinite replication of weaker infected and immortal cells. Chlamydia can spread in the body to infect new cells through direct migration, the blood stream, the lymphatics, and along the vagus nerve. Chlamydia can infect immune cells, weakening immune function. Chlamydia can have abnormal proteins attached to the surface of the pathogen and can cause normal proteins inside the cell to become abnormal proteins, which abnormal proteins can independently cause disease or attach to genes and cause genetic abnormalities. Inflammation, fungal invasion, reduced immunity, and defective genes can be the consequence of an infectious cascade begun by immortal chlamydia bacteria.
