Neochlamydiastrain S13 is an amoebal symbiont of anAcanthamoebasp. The symbiont confers resistance toLegionella pneumophilaon its host; however, the molecular mechanism underlying this resistance is not completely understood. Genome analyses have been crucial for understanding the complicated host–symbiont relationship but segregating the host’s genome DNA from the symbiont’s DNA is often challenging. In this study, we successfully identified a bimodal genomic structure inNeochlamydiastrain S13 using PacBio RS II supported by ultra-long reads derived from MinION. One mode consisted of circular sequences of 2,586,667 and 231,307 bp; the other was an integrated sequence of the two via long homologous regions. They encoded 2175 protein-coding regions, some of which were implied to be acquired via horizontal gene transfer. They were specifically conserved in the genusNeochlamydiaand formed a cluster in the genome, presumably by multiplication through genome replication. Moreover, it was notable that the sequenced DNA was obtained without segregating the symbiont DNA from the host. This is an easy and versatile technique that facilitates the characterization of diverse hosts and symbionts in nature.
