Antimicrobial resistance is a rising health risk of broad concern to countries and multiple sectors. It not only menaces the effective prevention and treatment of an ever-increasing range of infections but also results in reduced efficacy of antibacterial drugs. In intensively reared poultry, antibiotics are administered to whole flocks rather than individual animals. In addition to this, poultry farmers also use low doses of antibiotics as growth-promoting substances, which results in the high antibiotic selection pressure for resistance with a relatively high proportion of resistant...

Antimicrobial resistance has become a burning issue in humans and animals. Extended-spectrum beta-lactamase is produced by certain bacteria which has the capacity to inhibit the effect of third-generation cephalosporins and beta-lactam antibiotics. E coli being an indicator organism if it produces extended-spectrum beta-lactamase enzyme in healthy broilers it could be very alarming. The present study was conducted on caecal samples collected from freshly slaughtered healthy broilers, characterized both phenotypically and genotypically. The beta lactamase enzyme obtained was studied for the...
