A serological survey for antibodies to Leptospira (L.) interrogans in dairy and Korean native cattle in Gyeonghuk area was performed using 6 different living antigens, which were L. icterohaemorrhagiae(RGA), L. canicola(Hond Utrecht IV), L. autumnalis(Akiyami A), L. australis(Ballico), L. pomona(Pomona) and L. hebdomadis(Hebdomadis), by microscopic agglutination test. In the microscopic agglutination test, greater than partial agglutination at a serum dilution of 1:300 or over was recorded as positive.
In the dairy cattle(Holstein), four(4.7%) of 86 sera from 13 dairy farms were positive for L. canicola and L. pomona antibodies. In the Korean native cattle, four(3,2%) of 124 sera from the slaughter house in Taegu city were positive for L. canicola, L. icterohaemorrhagiae and L. pomona antibodies. Among the positive sera, L, canicola was dominated in this experiment.
