| Abstract: | A group of 144 wild mammals, including white-tailed deer, cottontail rabbits, fox squirrels, gray squirrels, raccoons, opossums, a bobcat, and various small rodents was examined for cultural or serologic evidence of leptospiral infection. Leptospires were isolated from 1 of 25 rabbits, 1 of 27 fox squirrels, 1 of 26 gray squirrels, 4 of 18 mice and rats, 8 of 21 raccoons, 7 of 17 opossums, and a bobcat. Isolations were not made from 6 deer examined. Serotypes isolated were Leptospira interrogans, serotype grippotyphosa and L interrogans, serotype ballum. New host-serotype relationships were noticed in the following instances: bobcat: grippotyphosa, and gray squirrel: ballum. These studies further confirm the occurrence of grippotyphosa in the fox squirrel. Serologic response in these animals did not necessarily correlate with isolations, although some relationship was noticed in raccoons and opossums. |
