Laboratory outbreak of Q fever acquired from sheep.
In April and May, 1981, an outbreak of Q fever occurred in a university department which used gravid sheep for fetal respiratory studies. During the subsequent investigation 91 people were studied and 28 were found to have complement-fixing antibodies to the phase II antigen of Coxiella burneti in their serum. Symptoms compatible with C. burneti infection occurred in 14 of the seropositive patients. The majority of symptomatic infections could be related to the delivery of twin fetuses in one laboratory, but some people remote from this incident who were exposed to sheep in other parts of the building also showed evidence of infection. Those people with serological evidence of recent infection were treated with tetracycline for 4 weeks. Defects were apparent in the facilities being used for the research and the risk of Q fever infection should be borne in mind by groups engaged in work with pregnant sheep.
