Abstract
Histological analysis of gill samples taken from individuals of Latris lineata reared in aquaculture in Tasmania, Australia, and
those sampled from the wild revealed the presence of epitheliocystis-like basophilic inclusions. Subsequent morphological, in
situ hybridization, and molecular analyses were performed to confirm the presence of this disease and discovered a Chlamydialike
organism associated with this condition, and the criteria set by Fredericks and Relman’s postulates were used to establish
disease causation. Three distinct 16S rRNA genotypes were sequenced from 16 fish, and phylogenetic analyses of the nearly fulllength
16S rRNA sequences generated for this bacterial agent indicated that they were nearly identical novel members of the order
Chlamydiales. This new taxon formed a well-supported clade with "Candidatus Parilichlamydia carangidicola" from the
yellowtail kingfish (Seriola lalandi). On the basis of sequence divergence over the 16S rRNA region relative to all other members
of the order Chlamydiales, a new genus and species are proposed here for the Chlamydia-like bacterium from L. lineata, i.e.,
"Candidatus Similichlamydia latridicola" gen. nov., sp. nov.
