Detection of Multi-Drug Resistant Food-borne Bacteria in Ready-to-Eat Meat Products in Luxor City, Egypt
A total of five Escherichia coli and eight Salmonella isolates were recovered from ready-to-eat meat samples obtained from different street vendors in Luxor city, Egypt. Bacterial isolates were assayed for antimicrobial susceptibility, its virulence and antimicrobial resistance genes. The total numb...
