| Abstract: | Chronic active hepatitis was diagnosed in five American Foxhounds from one kennel. Spirochetes were demonstrated in the liver in four of the dogs. A rising titer to Leptospira interrogans serovar grippotyphosa was found in the fifth dog, although spirochetes were not demonstrated in tissues. A serologic survey at the kennel revealed evidence of exposure of 6 of 13 dogs to grippotyphosa. This is the first report of an association between chronic active hepatitis leptospiral infection in any species. |
