Intervention or Control Points

Control of E. coli O157:H7 in Cattle by Competitive Exclusion Bacteria

Recovery of E. coliO157:H7 at necropsy (13 to 27 days postinoculation) from experimentally infected calves

E. coli O157:H7 (log CFU/g) in feces of cattle administered E. coli O157:H7 only

E. coli O157:H7 (log/g) at necropsy (day 33) in cattle administered E. coli O157:H7 only

E. coli O157:H7 (log/g) in feces of cattle administered E. coli O157:H7 and probiotic bacteria

E. coli O157:H7 (log/g) at necropsy (day 33) in cattle administered E. coli O157:H7 and probiotic bacteria
