On a property in the Nelson District, blood and urine samples were taken from red deer (Cervus elaphus) from which low (<1:100) antibody litres to serovarcopenhageniand suspected leptospiral abortions had previously been reported. A total of 27 hinds were sampled. Microscopic agglutination test (MAT) titres in sera ranging from 1:32 to 1:128 were found in six animals. Thirteen leptospiral isolations were made from nine of the 27 urine samples. Four of these were typed ascopenhageniand nine ashardjo. Two cultures were prepared from each urine sample andhardjoandcopenhageniwere both isolated from single urine samples from two animals. None of the 27 deer had serum MAT titres at 1:32 or above tocopenhageni.
