The Vir+ recombinant strains 711 v and H209av, which had received the Vir plasmid(s) from strain S5, also attached to these epithelia but the parent strains 711 and H209a without the Vir plasmid were non-adhesive. The attachment of the Vir+ strain 711 v to intestinal brush borders was inhibited by antiserum to live Vir+ strain H209av but not by antiserum to strain H209a lacking Vir. No adherence occurred with Vir+ organisms grown at 18 °C or after heating at 65 °C. Adhesion was unaffected by 0·5 % (w/v) formaldehyde. Glucosamine, mannosamine, their N-acetyl derivatives and wheat germ lectin each inhibited attachment of Vir+ strain 711v to brush border epithelia. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-128-9-2097
