Neochlamydia hartmannellae gen. nov., sp. nov. (Parachlamydiaceae), an endoparasite of the amoeba Hartmannella vermiformis
Article Abstract:
A study has extended knowledge of the phylogenetic diversity of the Neochlamydia hartmannellae gen. nov., sp. nov. (Parachlamydiaceae). It has been found that these endocytobionts can develop naturally in Hartmannella vermiformis amoebae. Free-living amoebae are more and more being seen to serve as vehicles of dispersal for assorted bacterial human pathogens. They also can be hosts for various obligate bacterial endocytobionts.

In situ detection of novel bacterial endosymbionts of Acanthamoeba spp. phylogenetically related to members of the order Rickettsiales
Article Abstract:
The morphology and phylogeny of two gram-negative rod (GNR) endosymbionts infecting axenically maintained isolates of Acanthamoeba that have been recovered from patients with amoebic keratitis have been studied. Acanthamoebae are soil and water bactivores which function as amplification vehicles for several pathogenic facultative bacteria and as hosts to other uncultured bacterial endosymbionts. Results reveal the two GNR endosymbionts have a 99.6% sequence similarity and form an independent lineage within the Rickettsiales branch of the alpha subdivision of Proteobacteria.
