Abstract
- Chlamydiae are pathogenic and symbiotic bacteria, which form an important part of amoeba-associated microorganisms. In this paper, we report the isolation, developmental cycle and genome analysis of Protochlamydia phocaeensis sp. nov., an obligate intracellular parasite with a large host spectrum, able to infect Acanthamoeba castellanii, Acanthamoeba polyphaga, and Vermamoeba vermiformis. The genome size is 3,424,182 bp with a GC content of 42%. This bacterium displayed a particular developmental cycle depending on the infected host. The P. phocaeensis showed typical inclusion vacuoles in A. castellanii, while these were absent in V. vermiformis. Since "Chlamydiae-amoebae" interactions are supposed to depend on the chlamydial species, our findings speculate that variations in the developmental cycle of certain Chlamydiae are also host dependent.<br /> (Copyright © 2017 Institut Pasteur.
