title: Hemagglutinating properties of Shigella dysenteriae type 1 and other Shigella species.
abstract: Strains of Shigella dysenteriae type 1 cultured in Casamino Acids-yeast extract broth medium in the presence of 1 mM calcium chloride at 37 degrees C for 22 h induced hemagglutination of erythrocytes that was inhibited by N-acetylneuraminic acid, N-acetylneuramin-lactose, and alpha 1-glycoprotein. The hemagglutination was heat labile, and the absence of cell-surface appendages suggested a nonfimbrial adhesin(s). Under the same conditions, strains of Shigella flexneri (types 1a, 1b, 2a, and 2b) showed N-acetylneuraminic acid-resistant hemagglutination of erythrocytes.
