The last report of swine brucellosis in Switzerland was in 1946. Investigation of infertility and abortion among 16 sows of one herd included serological testing with B. abortus antigen by agglutination, mercaptoethanol and CF tests. 7 of 11 sows were positive, and titres were high in three that had aborted. B. suis was isolated at slaughter from two positive sows. The entire herd was slaughtered to prevent the spread of infection. The authors suggested that the infection could have been acquired from paddocks contaminated by infected hares.
