title: The taxonomic status of the causative agent of heartwater.
abstract: A fresh pragmatic classification of the rickettsias has been derived by applying the simplest techniques of numerical taxonomy. One order, the Rickettsiales, containing 3 families, the Rickettsiaceae, Phagosomaphilaceae, and the Bartonellaceae (?) is proposed. Cowdria is classified as a genus along with Chlamydia, Coxiella and Anaplasma in the tribe Chlamydieae in the family Phagosomaphilaceae.
