Q fever in pregnancy: case report after a 2-year follow-up

We report an acute Q fever case, a febrile syndrome, in the 14th week of pregnancy. Placental infection was documented by Coxiella burnetii culture. Newborn infection was ruled out on the basis of the absence of serological evidence after 2 years and on clinical normality. Serological diagnosis is reviewed here, as maternal serology was suggestive of chronic Q fever. The clinical progress, following extended observation, was consistent with acute infection. A QpDV plasmid, already described as being common to acute and chronic European cases, was detected.
