Popis: | Cells of E. coli isolates from the gut of healthy volunteers (N=5) and patients with Crohn's disease (N=5) and laboratory E. coli strain DH5α bound mucin in vitro in similar amounts ranging from 0.02 to 0.12 mg/mg of bacterial dry weight. Binding was evaluated by the decrease in optical absorption of mucin solution at 214 nm after incubation with bacteria. Detailed analysis of mucin binding by one of isolates showed that during incubation of 0.09 mg/ml bacteria in 0.15 M NaCl containing 0.1 mg/ml mucin at 25oC, maximum binding was reached in 30 min, while in the presence of 14 mM α-methyl mannoside, mucin binding decreased by 46% (p |
