rhabdochlamydia rhabdochlamydia candidatus rhabdochlamydia is a genus of intracellular bacteria and the sole genus in the family candidatus rhabdochlamydiaceae. as a candidatus taxon, no-one has yet managed to culture them in vitro for deposition in a culture collection. rhabdochlamydia scientific classification domain: bacteria phylum: chlamydiota class: chlamydiia order: chlamydiales family: rhabdochlamydiaceae genus: rhabdochlamydiakostanjsek et al. 2004 type species "ca. rhabdochlamydia porcellionis"kostanjsek et al. 2004 species see text two rhabdochlamydia species have been characterized and validly proposed. their ribosomal rna genes are 96.3% identical. these gene sequences are 82%–87% identical to those of most chlamydiales. these data and analysis of rhabdochlamydia morphology indicates that these species belong to the bacterial order chlamydiales. species the genus consists of the following two valid species: candidatus rhabdochlamydia crassificans kostanjšek et al. 2004 – detected in the cockroach blatta orientalis candidatus rhabdochlamydia porcellionis corsaro et al. 2006 – detected in hepatopancreas of the woodlouse porcellio scaber
