Coxiella burnetii is a small gram-negative bacterium. It is not in the Rickettsial genus, but is closely related and is an obligate intracellular organism that requires CoA and NAD for survival. However, unlike the other Rickettsial infections, Coxiella is not transmitted by an arthropod vector, does not cause a rash, and has a negative Weil-Felix reaction.
Unlike the other Rickettsial infections, Coxiella does not have an arthropod vector through which it is transmitted.
Unlike the other Rickettsial infections, Coxiella does not cause a rash.
A Weil-Felix reaction is seen in patients with Rickettsial infections other than Coxiella. When patient serum with Rickettsial antibodies is mixed with Proteus antigens, the antiricketssial antibodies cross-react to Proteus O antigens and cause agglutination. Unlike the other Rickettsial infections, Coxiella causes a negative Weil-Felix reaction.
This organism is common in cattle, sheep, and goats and can be acquired via inhalation of spores from contaminated birthing products like cattle placenta. Due to this mode of transmissions, at risk occupations include veterinary personnel, farmers, and shearers.
Q fever is the disease caused by Coxiella burnetii and commonly manifests as flu-like symptoms with fever, malaise, myalgia, nausea, vomiting, and diarrhea. During the course of disease, it can progress to a pneumonia, which can result in life-threatening acute respiratory distress syndrome.
