adhesin

(noun)

Any of several factors that enable bacteria to adhere to epithelial surfaces as a step towards infection.

Examples of adhesin in the following topics:

  • Adherence

    • Adhesins are a type of virulence factor.
    • Most fimbriae of Gram-negative bacteria function as adhesins, but in many cases the actual adhesin is a minor subunit protein at the tip of the fimbriae.
    • In Gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin.
    • The effectiveness of anti-adhesin antibodies is illustrated by studies with FimH, the adhesin of uropathogenic Escherichia coli (UPEC).
    • Review the role of adhesins, including fimbriae and the Dr family, in pathogenic bacteria
  • Pathogenicity Islands and Virulence Factors

    • PAIs carry genes encoding one or more virulence factors, including, but not limited to, adhesins, toxins, or invasins.
  • Otitis Media

    • Otitis media caused by bacterial infections are due to Trimeric Autotransporter Adhesins (TAA; proteins found on the outer membrane of Gram-negative bacteria .
  • Whooping Cough

    • The bacterium contains a surface protein, filamentous haemagglutinin adhesin, which binds to the sulfatides found on the cilia of epithelial cells.
  • Pathogenicity Islands

    • Pathogenicity islands carry genes encoding one or more virulence factors, including, but not limited to, adhesins, toxins, or invasins.
  • Plague

    • Y. pestis expresses the yadBC gene, which is similar to adhesins in other Yersinia species, allowing for adherence and invasion of epithelial cells.
