This study investigated the occurrence of ESBL-producing Escherichia coli on two Czech dairy farms with different livestock management practices and antibiotic policies. Farm A was a conventional intensive farm characterized by high consumption of cephalosporin antibiotics. Ceftiofur (third generation cephalosporin) was the antibiotic with the highest frequency of use for treatment in several indications, followed by amoxicillin–clavulanic acid, cefoperazone, and a penicillin plus neomycin combination during recent years (2005–2008). Farm B was certified as an organic farm and had low antibiotic consumption. Tetracycline was the most frequently used antibiotic and was administered using an injectable product. It used an oxytetracycline-containing veterinary medicinal product for administration to calves. Also administered on the farm were oxytetracycline and neomycin in combination, a streptomycin and sulphonamide combination, a penicillin and dihydrostreptomycin combination, and a cloxacillin and neomycin combination. No third and fourth generation cephalosporins were used on the farm.
