[Q fever and fetal death in utero. Two cases].

Some cases of late abortion occurring after a Coxiella burneti infection, more often with a chronic evolution, have already been mentioned in the literature. We reported here two cases of early abortion, contemporaneous of an acute infection due to C. burneti. Two patients, after a contact, before and at the beginning of the pregnancy, with an animal susceptible to contaminate human beings by C. burneti, presented no clinical symptom characteristic of Q fever. The fetal death for the two cases was found out at the 17th week of amenorrhoea. All the investigations in order to search for an abortion etiology remained negative. Only, the specific serologies showed an acute infection due to C. burneti.
