===Overview===
*Host adapted and non-host adapted species varying in virulence for different hosts
*Repsiratory, enteric, pleural and reproductive diseases in animals and humans
*Intestinal infections often subclinical and persistent
**Elementary body, the infective extracellular form, which is small, metabolically inert and osmotically stable; surrounded by cytoplasmic membrane, outer membrane with LPS, but no peptidoglycan

**Retiuculate body: larger, metabolically active, osmotically fragile
**Retiuculate body: larger, metabolically active, osmotically fragile
*Elementary body survives in the environment for several days
*Persistent infections can occur if replication delayed by environmental conditions
*Persistent infections can occur if replication delayed by environmental conditions
*Many infections subclinical due to intracellular existence of ''chlamydia'' preventing inflammatory reactions
*Many infections subclinical due to intracellular existence of ''chlamydia'' preventing inflammatory reactions
*Prolonged faecal shedding of organisms
*Clinical infections occur in non-natural host species
*Clinical infections occur in non-natural host species
