Abstract
Extract
Leptospirosis is occasionally diagnosed in sheep in New Zealand. Hartley Citation(1952), Salisbury Citation(1954), and Webster and Reynolds Citation(1955) have reported outbreaks in which icterus, haemogiobinuria, and high mortality were the principal clinical features, but in which asymptomatic infections were also recorded. However, no surveys to establish the incidence of leptospirosis in sheep in New Zealand have been reported. Bovine leptospirosis is common in some parts of New Zealand and since cattle and sheep may sometimes graze the same pastures the possibility of interspecies transmission should not be overlooked
