Answer: co-trimoxazole
Q fever is caused by infection with Coxiella burnetii. This organism is found in cats, dogs, cattle, sheep, goats and other domestic mammals. Infection results from inhalation of endospores, and from contact with the milk, urine, feces or body fluid of infected animals.
Q fever can be treated with antibiotics - doxycycline, tetracycline, chloramphenicol, ciprofloxacin, ofloxacin, and hydroxychloroquine.
Q fever in pregnancy may cause abortions particularly in the first trimester. As doxycycline and ciprofloxacin are contraindicated in pregnancy, the preferred treatment is co-trimoxazole for the duration of pregnancy.
