The study was designed with the aim to isolate and test the drugs sensitivity of E.coli and Salmonella from poultry droppings from the farms located in and around Jabalpur as these are enteropathogenic bacteria and may cause different disease conditions in poultry birds, moreover Salmonella can transmit through horizontal and vertical route of transmission. All the isolates were confirmed by standard microbiological procedures. The results of the present study revealed that out of 120 samples, 60 samples were found positive for E.coli, 25 were positive for Salmonella and 12 samples were found positive for both bacteria. The higher rate of occurrence was recorded in fresh droppings in comparison to old droppings. Antibiotic sensitivity test with 8 commonly used antibiotics for the treatment of enteritis in poultry revealed that Gentamicin was the most effective inhibitor of E.coli. All the isolates of E.coli were resistant for Nalidixic acid, Sulfamethoxazole and Oxytetracycline. All the isolates of Salmonella spp showed maximum sensitivity to Ciprofloxacin and showed cent per cent resistance towards Sulfamethoxazole and Oxytetracycline.
