Abstract
Extract
Recognition that one infective agent could cause ram epididymitis and ewe abortion in New Zealand was due to McFarlane et al. (Citation1952). The organism was not identified at that time, but Buddie and Boyes (Citation1953) classified it in the genus Brucella—possibly a variant of Br. melitensis. This finding provided a basis for research on control and treatment of the disease. The present paper describes studies on one aspect of this problem, the chemotherapy of affected rams.
