Gene copy numbers for virulence factors (heat-stable enterotoxins [STa and STb], heat-labile enterotoxin [LT] of enterotoxigenic Escherichia coli, and heat-stable enterotoxin [EAST1] of enteroaggregative E. coli) in feces of pigs fed diets supplemented with cellulose (white bars), carboxymethylcellulose (light gray bars), low-viscosity oat β-glucan (dark gray bars), or high-viscosity oat β-glucan (black bars). The detection limit was 3 log10 gene copies/g (wet weight).
