Coxiella burnetii

چکیده
Q fever has been described for the first time in 1935 as an outbreak of fever in workers of a slaughterhouse in Brisbane, Australia (Derrick, 1937). Derrick could not identify the aetiological agent therefore he defined the disease as “query fever”. Afterwards, in 1937, Burnet and Freeman (Burnet & Freeman, 1937) isolated a troublesome intracellular pathogen from mice inoculated with blood or feces from Derrick’s patients, and classified it as Rickettia burnetii. Only in 1948 Philip (Philip, 1948), according to cultural and biochemical characteristics, re-classified R. burnetii as a new genus, Coxiella, in honour of Herald R. Cox, who first isolated this microrganism in the USA.
