ABSTRACT
The structural gene encoding the 16S rRNA of the new obligate intracellular organism presently designated WSU 86-1044Twas sequenced and analysed to establish its phylogenetic relationships. The 16S rDNA sequence was most closely related to those of chlamydial species, having 84.7--85.3% sequence similarity, while it had 72.4-73.2% similarity with rickettsia-like organisms. When the sequences of the four species of chlamydiae and Chlamydophila psittaci, Chlamydia trachomatis, Chlamydophila pneumoniae and Chlamydophila pecorum) were compared, they had > 93% sequence similarity indicating tha WSU 86--1044Twas not close enough to be in the same family as current Chlamydiaceae members. However, based on the 84.7--85.3% 16S rDNA sequence similarity of WSU 86--1044Tand other previously described characteristics, WSU 86--1044Tbelongs to a novel family within the order Chlamydiales; hence, the proposal of Waddliaceae fam. nov., Waddlia chondrophila gen. nov., sp. nov.
Key Words: chlamydia • phylogeny • 16S rRNA • 16S rDNA sequence • abortion
The GenBank accession number for the 16S rRNA gene sequence of WSU 86-1044Tis AF042496.
