The prevalence of different porcine phenotypes in the Netherlands concerning adherence of K88-positive Escherichia coli to intestinal epithelium.

Jejunal brush border samples from 101 pigs were tested for the presence of K88 receptor sites. Specific adhesion of K88-bearing microorganisms did not occur in nearly 50 percent of the samples. About 40 percent of the test samples were adhesion positive for the prevailing K88ac antigen. The different porcine phenotypes were equally distributed over the country.
