Streptococcal meningitis broke out among piglets 40 100 days old on a farm in Mie Prefecture over a period from February to December, 1980. It was started with pyrexia over 40°C, ataxia, and crouching like dogs. Affected piglets lay on the side, trembled, and paddled with all the four extremities. The main autopsy finding was thick opalescent turbidity of the meninges. Histological examination revealed purulent meningitis of the central nervous system. Streptococci were isolated from the brain, lung, liver, spleen, kidney, and joint. Judging from their biological characters and serological typing, they were probably identical with Moor's group R streptococci.
