Abstract:

Epididymitis of rams in New Zealand has been shown to be a common symptom of infection with a Brucella mutant (Buddie and Boyes, 1953). Naturally and experimentally infected rams do not invariably develop clinically detectable lesions, although still capable of disseminating infection in the semen in considerable concentration over protracted periods. Natural and experimental infection of ewes has been shown to result in placentitis with abortion or neo-natal death of lambs. The infective organisms may be excreted from ewes with the placentae, dead lambs, vaginal discharges, milk, and probably with the urine and faeces.
