PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Coxiella burnetii is an obligate intracellular pleomorphic gram-negative coccobacillus that was originally named Rickettsia burnetii. Extensive changes in the taxonomy of rickettsiae based on the sequencing of the 16S rRNA has resulted in the removal of Cburnetii from the order Rickettsiales and now finds it in the order Legionellales falling into the gamma group of proteobacteria along with Legionella pneumophila, and Francisella tularensis.1,2 The reader should not become too comfortable with this new classification because as new Coxiella-like organisms are found, the phylogenetic relationships of this group of organisms will be readdressed in the future.
