Abstract: Three red deer calves (Cervus elaphus) died with a haemolytic disease associated with infection by Leptospira interrogans serovar pomona. Infection within the herd was more prevalent than disease. Sera from 16 herd mates were tested by the microscopic agglutination test (MAT) and 12 had leptospiral titres, the majority to serovarpomona. A few calves had titres to balcunica and hardjo. Urine was obtained for culture from six of these calves and serovarpomona was isolated from five with titres topomona, and hardjo from one with a titre to hardjo but not pomona. A fourth calf died with severe nephritis but a diagnosis of Ieptospirosis was not confirmed in this case.
