Serological reactions to Leptospira species in game animals of northern Natal

Fifty sera collected from 12 different species of free-living game animals in game parks in the Northern Natal were tested against 8 Leptospira interrogans antigens using the microscopic agglutination test (MAT). Six out of 50 animals had titres, all less than 100. Three of these animals had titres to serovar mini, 1 animal to tarrasovi, and 3 animals had multi-serovar reactions, 1 to mini and hardjo, and 1 to tarrasovi, copenhageni and pomona.
