The isolation of Yersinia enterocolitica from the cecal contents of swine was dependent on season. The organism was isolated more frequently in winter to early spring than in summer. No relationship could be established between rate of isolation and serogroup distribution of organisms isolated from swine at three abattoirs in Kurayoshi, Hiroshima and Fukuoka. Even if such differences are recognized, more emphasis should be put upon the feed type used on each farm than upon the regional factors. There was no difference in organisms recovered between swine given formula feed and those given garbage.
