These organisms cannot produce energy and thus survive by acting as a parasite using the energy mechanics of their infected host; they all have biphasic cycles of replication. The elementary body that represents the “infectious” particle enters the host cell and lives within the host’s cytoplasmic inclusion particles. The organism then begins its secondary vegetative state known as the reticulate body and replicates by binary fission. Each inclusion body begins to form multiple progeny that will be extruded as new infectious elementary bodies to begin the cycle once again.
