| Abstract: | Bacteria closely related to chlamydiae live and multiply as endocytobionts within free-living amoebae, making these amoebae potential vehicles of new emerging bacterial pathogens of humans. Hartmannella vermiformis containing endobiotic Neochlamydia hartmannellae grew more rapidly than those without endobionts, whilst Acanthamoeba sp. harbouring the Parachlamydia-related endocytobiont UWE25 multiplied more slowly than those without endobionts. The cause for the opposite effect of chlamydial endocytobionts on the growth of their host cells remains unknown. |
