In the context of our study of the animal side, especially in broiler chickens, the breeding of the latter requires the use of antibiotics for treatment and prophylaxis purpose; to give a closer look at the antibiotic resistance status of broiler chickens in Western Algeria. The bacteria Enterobacter, Escherichia coli, Proteus, Salmonella, Serratia were present and showed a high multidrug-resistance at a percentage of 67.14%, 63.64%, 60%, 57.27%, 50% respectively. The forty-nine bacteria identified belong to different families of Enterobacteriaceae, Yersiniaceae and Morganellaceae have shown an overall resistance of 61.22%. Presented resistance to cefazolin 91.84%, flumequine 89.80%, neomycin 83.67%, ceftiofur 79.59%, ampicillin 73.47%, trimethoprim 73.47%, aztreonam 57.14%, colistin 48.98 %, nadilixic acid 32.65%, streptomycin 30.61%, gentamicin 12.24%. To study the sensitivity, critical values to antibiotics a statistical Student's t-test was used. All bacteria were significantly resistant (P ≤ 0.05) to the following antibiotics: flumequine, neomycin, cefazolin, trimethoprim, ampicillin, and ceftiofur. However, a low sensitivity was also noted to gentamicin, nalidixic acid, streptomycin (P ≤ 0.05). Some isolated bacteria were resistant to many antibiotics, with resistance from 3 to 10 antibiotics simultaneously. The highest percentage of all bacteria (28.57%) were resistant to 8 antibiotics, while the lowest percentage of all bacteria (2.04%) were resistant to 3 and 10 antibiotics.
