During 1975 to 1977, serum samples were collected from 101 adult coyotes (Canis latrans) captured in northcentral Kansas. Ten samples were seropositive by microagglutination testing and six of those samples were seropositive for multiple serovars. Titers for Leptospira interrogans serovars grippotyphosa, pyrogenes, djasiman, butembo, and pomona were demonstrated.
