Isolation of leptospira hardjo from the opossum (trichosurus vulpecula)
Extract
Sir, — In 1971 and 1972 the Department of Health and the Ministry of Agriculture and Fisheries conducted surveys on the incidence of leptospirosis among fanners and their stock on the Hauraki Plains. As a result, Leptospira hardjo was identified for the first time in New Zealand, being isolated from humans (Christmas et al., Citation1974) and from dairy cattle (Lake, Citation1973). Evidence to date suggests that most human infections in New Zealand, whether of L. hardjo or of other serotypes, are contracted while milking.
