Abstract: | Ten gut and ten vaginalLactobacillus strains were investigated for their ability to bind type I collagen (Cn-I) and four selected gut lactobacilli were investigated
for their binding to other extracellular matrix (ECM) molecules. Immobilized Cn-I (100 mg/L) in wells of microtitre plates
was bound by all 10 autoaggregating vaginal strains and by 3 strains of gut lactobacilli from piglets in the range ofA
570 readings 0.114–1.806.L. acidophilus strain SV31 was much more adherent than the rest of strains. All four gut lactobacilli tested for binding to other ECM molecules
displayed good binding to porcine fibronectin and heparin and some of them bound weakly to fetuin and porcine mucin. No binding
of these strains was observed to bovine mucin, bovine fibrinogen and bovine lactoferrin. |
