[Diagnostic measures on the occasion of a Q-fever epidemic in a sheep flock in Berlin].

This report gives an account of a Q-fever infection in flocks of sheep, taking into consideration the epidemiological aspects. In the inner organs, and particularly in the central nervous system of affected animals, rickettsial as well as chlamydial agents were directly demonstrated by immunofluorescence and specific staining methods, as well as by isolation via cell culture. Serological examination showed antibodies against both agents in sheep from flocks where the outbreak occurred.
