Coxiella burnetii , the causative agent of Q fever
Scientific classification
Domain:	Bacteria
Kingdom:	Pseudomonadati
Phylum:	Pseudomonadota
Class:	Gammaproteobacteria
Order:	Legionellales
Family:	Coxiellaceae
Genera [1]
Aquicella Coxiella Diplorickettsia Rickettsiella "Ca. Berkiella"

The Coxiellaceae are a family in the order Legionellales. ^{[2] [3]}

Coxiella burnetii is the best-described species in this group.

The bacterium Rickettsiella melolonthae was initially assigned to the Coxiellaceae ^[3] , but is considered part of the Diplorickettsiaceae (a closely related lineage of Gammaproteobacteria) based on recent phylogenomic reconstructions ^{[4] [5]} .

Various other Coxiellaceae lineages have so-far evaded cultivation efforts but have been characterized through culture-independent genomics and are present in both freshwater and diverse marine environments, likely with a host-associated lifestyle similar to that of Coxiella burnetti ^[6] .
