Adherence of Helicobacter pylori to abiotic surfaces is influenced by serum.
Helicobacter pylori bacteria cultured in a chemically defined medium without serum readily adhere to a variety of abiotic surfaces. Growth produces microcolonies that spread to cover the entire surface, along with a planktonic subpopulation. Serum inhibits adherence. Initial attachment is protein mediated, but other molecules are responsible for more permanent attachment.
