Résumé:
The objective of our study is to assess the degree of resistance acquired by strains of Escherichia Coli in a poultry farm in the Constantine region. 100 samples of droppings were taken at random from broilers treated with antibiotics. Antibiotic results show that these strains of Escherichia Coli have developed resistance to commonly used antibiotics, cyclins, quinolones, amoxicillin, sulfamethoxasole-trimethoprim.
