The serology of 87 strains of Plesiomonas shigelloides was studied. Thirty O antigenic groups and 11 H antigens were defined within the 87 strains, and an antigenic schema consisting of 40 serovars was established. Some O antigens of P. shigelloides were identical or closely related to those of some Shigella serovars.
