ABSTRACT Background: The development of intensive farming in the poultry industry has been accompanied by a massive use of antibiotics for the treatment, prevention of infections and for improving animal performance. Antibiotic resistance is a real problem in veterinary medicine with a major impact in terms of public health. Objective: The main goal of this study is the surveillance and monitoring of antimicrobial resistance among E. coli strains isolated from broilers in the Greater Casablanca region. Materials and Methods: 42 samples were taken for 200 broilers; identification of isolated bacteria was carried out with a classic gallery showed the presence of E. coli in all samples and underwent antibiogram tests towards the most antibiotic disks used on the (Mueller Hinton) MH agar. Results: The results showed a very good response towardscolistin (87.41%) and spectinomycin (52.94%), and trimethoprim-sulfamethoxazole (67.56%). As against the sharpest resistance concern oxytetracyclines (97.05%), amoxicillin (88.23%), enrofloxacin (76.36%), doxycycline (73.52%), céfalotin (60%). A low to medium sensitivity is seen with nalidixic acid (50.20%), flumequine (48.88%). Conclusion: The undue and sustainable use of antibiotics has led to the emergence of resistant bacteria (Escherichia coli) to these drugs indeed, these resistors have become the rub of farmers and scientists and that lead to the implementation of various strategies to avoid situations of therapeutic impasses. Key words: antibiotics, antibiotic resistance, broiler. Infection, public health.
