Abstract

ABSTRACT Of 469 recently isolated Shigella flexneri strains, 452 agglutinated with Shigella flexneri -specific monoclonal antibodies. Of these, 396 could be assigned to 10 of the currently recognized 15 serotypes, with S. flexneri 2b dominating (23.2%). Of the 56 untypeable strains which showed invasive properties, 17 were serologically atypical and the remaining 39 belonged to a new serotype.
