摘要

In initial studies of slide and tube agglutination tests of shigella-like isolates from diarrheal stools from Bangladesh, 10 and 8 strains of Shigella dysenteriae were identified as provisional serovars (serovars that have been defined but not given a number in the antigenic schema) E22383 and E23507, respectively. Further screening of diarrheal stool isolates in a slide agglutination test with antisera (made with the international reference strains) to the two provisional serovars of S. dysenteriae identified an additional 36 isolates as belonging to E22383 and 8 isolates as belonging to E23507. All strains had properties typical of invasive Shigella strains in that they were positive in the Sereny test and had the 120- to 140-MDa plasmid associated with invasiveness. On the basis of these markers of pathogenicity and isolation from various geographical locations, now we recommend that provisional serovars E22383 and E23507 be designated S. dysenteriae serotypes 14 and 15, respectively.
