Enteritidis and12 (20.33%) other Salmonella spp. While screening of all the Salmonella isolates by conventional PCR, 58 (98.30%) isolates were found positive for invA gene. These isolates were found censitive to Ampicillin (90.74%) followed by amoxyclav (87.03%), amoxycillin (85.18%) and cefotaxime (81.48%) while resistant to nalidixic acid (96.29%), oxytetracycline (79.62%) and doxycycline (72.2%).
