Simkaniaceae

Simkaniaceae is a family of bacteria in the order Chlamydiales, class Chlamydiae, phylum Chlamydiae, domain Bacteria. Species in this family have a chlamydia-like cycle of replication and their ribosomal RNA genes are 80–90% identical to ribosomal genes in the Chlamydiaceae. The Simkaniaceae are not recognized by monoclonal antibodies that are specific for Chlamydiaceae lipopolysaccharide. The family Simkaniaceae currently includes two genera: Simkania and Fritschea. The type species is Simkania negevensis, and its natural host is not known. It is readily grown in monolayers of eukaryotic Vero cells. Serological evidence and PCR indicate that S. negevensis is widespread among humans.
