[The problem of Q fever in zoo ungulates].

Antibodies to Coxiella burnetii were recorded from approximately 13% of 469 ungulates which had been examined by means of micro-CFT (complement fixation test). Particular reference is made to a Q-fever situation in a musk ox herd. The results obtained from these investigations are likely to support the conclusion that latent Q-fever infection may be expected to occur in ungulates and to grow manifest in stress situations.
