abstract
Resistance against frequently used antibiotics has become a serious cause of concern in poultry management and disease control. Hence a study was carried out to know the antibiotic sensitivity pattern using the commercially available antibiotics for 341 isolates from 252 samples isolated from birds exhibiting signs of bacterial infection. The results revealed that bacterial isolates had maximum sensitivity for Ampicillin, Ciprofloxacin and Gentamicin followed by Amoxicillin. Kanamycin and Sulphamethaxazole were found to be the most intermediately sensitive antibiotics. Erythromycin and Tetracycline were the most resistant antibiotics.
