Abstract
Extract Bovine leptospirosis is a disease of major importance in New Zealand and is widespread in dairy cattle, in the North Island. Recent surveys have shown an increasing incidence of leptospiral abortion in dairy cattle (Cagienard, 1973 Cagienard, B. 1973. Some observations on disease incidences among dairy cattle in North Taranaki. N.Z. vet. J., 21: 170–174. [Taylor & Francis Online] [Google Scholar] ) and Leptospira interrogans serotypes copenhageni and ballum have been isolated from, apparently healthy calves (Ris et al., 1973 Ris, D. R. , Lake, D. E. and Holland, J. T. S. 1973. The isolation of Leptospira serotypes copenhageni and ballum from healthy calves. N.Z. vet. J., 21: 218–220. [Taylor & Francis Online] [Google Scholar] ). The disease is an important occupational hazard of the dairy farmer, and the incidence of the disease in man in New Zealand is considerably higher than in any other country for which vital statistics are available. In 1971, 860 human cases were notified in New Zealand (Anon., 1972 Anon. Report of the Department of Health for the Year ending March 31, 1971 1972 [Google Scholar] ) with a population of less than three million compared with 60 cases from the U.K. in 1972 with a population approaching 60 million ( Anon., 1973 Anon. Leptospirosis in 1972 Br. med. J 1973 723 723 [Google Scholar] ).
