Adhesion of Some Bacteria to Broiler Intestinal Mucus
细菌对肉鸡肠粘液的粘附作用

The objective of the study was to investigate adhesion of Bifidobacterium bifidum, Lactobacillus acidophilus, avian Escherichia coli O78, E. coli ATCC 25922, Salmonella pullorum and S. typhimurium, and the effects of B. bifidum and L. acidophilus on these adhesions. The results showed that there were different adhesion properties of B. bifidum, L. acidophilus, S. pullorum and S. typhimurium to mucus glycoproteins in different intestinal parts. But avian E.coli O78 or E. coli ATCC 25922 had a similar adhesion to different intestinal mucus. The adhesions of tested probiotic bacteria to the same intestinal mucus were higher than that of pathogenic bacteria. B. bifidum and L. acidophilus had different inhibition to adhesion of the tested pathogens to intestinal mucus, and sometimes they also had complementary action against pathogen adhesion.
