Abstract

The lectin-like activity of the Lactobacillus acidophilus strain JCM 1026 was studied by hemagglutination and hemagglutination-inhibition assays. L. acidophilus strain JCM 1026 was found to hemagglutinate human and animal erythrocytes. Neuraminidase-treatment of human-type O erythrocytes enhanced the activity. Treatment of the bacterial cells with proteinase K reduced hemagglutinating activity significantly. Although several mono- and disaccharides did not inhibit hemagglutination, several different glycoproteins did. These data indicate that a proteinaceous lectin-like component(s) recognizing carbohydrate-containing molecules is located on the cell surface of L. acidophilus.
