Abstract: Whether endosymbionts can survive amoebal encystations remains a significant challenge in cellular biology. The survival of the endosymbiotic bacteria Protochlamydia belonging to environmental chlamydiae in acanthamoebae following encystation was therefore assessed. The bacteria were observed in cysts and the bacterial transcripts (16S rRNA and/or groEL) were also detected in amoeba cultures following encystation. Furthermore, the bacterial replication and the growth was confirmed in trophozoites reverted from cysts. Thus, these results demonstrated that Protochlamydia could survive in acanthamoebae following encystation. Our findings suggest that amoeba cysts might be further studied in order to elucidate the their role in the environmental survival of endosymbionts.
