    Sejarah


    Penelitian pada tahun 1920-an dan 1930-an mengidentifikasi organisme yang tampak seperti Rickettsia tipe baru yang diisolasi dari kutu. Deskripsi pertama dari organisme yang mungkin adalah Coxiella burnetii diterbitkan pada tahun 1925 oleh Hideyo Noguchi, tapi karena sampel itu tidak bertahan hidup, masih belum jelas apakah itu organisme yang sama. Uraian definitif diumumkan di akhir 1930-an sebagai bagian dari penelitian penyebab demam Q, oleh Edward Holbrook Derrick dan Macfarlane Burnet di Australia, dan Herald Rea Cox dan Gordon Davis di Rocky Mountain Laboratorium (RML) di Amerika Serikat.
