Figure 1  Adherence of L. amylovorus strains to mucus. The adherence of L. amylovorus strains to immobilized porcine gastric mucin (type II, Sigma) (A) and to mucus purified from porcine small intestine (B) was studied using bacterial cells labeled with the fluorescent dye SYTO®9. The means and standard deviations of 5–8 independent experiments are shown, each with three technical replicates.
