During the period between October 1980 and July 1982, diarrhea! cases were examined for the enteropathogens in Kenya. Shigella was isolated from 275 cases including 198Shigella flexneri out of 1,199 cases examined. Twenty-nine strains out of the 198 Shigella flexnen belonged to serotype 4. Among these 29 type 4 strains, only 3 could be subtyped into 4a and 4b in accordance with the established serotype. The other 26 strains exhibited no group antigens 3,4, or 6. And some strains of these 26 lacked all group antigens but the others had group antigens 7,8. The agglutination pattern of these organisms against anti Shigella flexneri type and group antigens sera was not changed by heat treatment of the organisms. The majority of the strains having no group antigens did not ferment mannitol. Shigella flexnen type 4 with group antigens 7,8 (IV : 7,8) has rarely been reported, but this kind of strains were the most frequent isolates in Kenya as far as this species is concerned. This fact suggested that a new subtype can be established.
