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