An order of obligately intracellular, gram-negative bacteria that have the chlamydia-like developmental cycle of replication. This is a two-stage cycle that includes a metabolically inactive infectious form, and a vegetative form that replicates by binary fission. Members of Chlamydiales are disseminated by aerosol or by contact. There are at least six recognized families: CHLAMYDIACEAE, Criblamydiaceae, Parachlamydiaceae, Rhabdochlamydia, Simkaniaceae, and Waddliaceae.

  • showed the presence of Chlamydia -like inclusions in a cyst of Acanthamoeba ( 7 ), suggesting that amoebae could also act as Trojan horses for the Parachlamydiaceae , since amoebae are resistant to various disinfecting solutions ( 5 , 20 , 26 ) and to extreme temperature, pH, and osmolarity conditions while encysted (reviewed in reference 18 ).

  • Free-living amoebae like Acanthamoeba are ubiquitous in soil and water environments, in which they prey on bacteria, thereby controlling bacterial populations and enhancing nutrient recycling ( 1 , 2 ). (asm.org)
  • The latter, Parachlamydia acanthamoeba , could be pathogenic for humans ( 7a ). (asm.org)
