Abstract

The purpose of this study was to investigate possible phylogenetic relationships of a new microorganism called 'Z'. The organism was previously shown to be similar to chlamydia in its growth cycle and some of its metabolic requirements, but different in others and in its major outer membrane protein. In this study we report the sequencing of 'Z''s 16S ribosomal DNA and comparison of the sequence with that of other microorganisms, including chlamydia and rickettsiae. While chlamydial species have 95.5% sequence identity among themselves, 'Z' had 83% identity with them, and 73% identity with certain rickettsia-like organisms. Based on the sequence analyses and taking into account physiologic considerations, we believe that 'Z' may belong to a novel genus in the family Chlamydiaceae.
