Pathovars, occurrence, and characterization of plasmid-mediated quinolone resistance in diarrheal Escherichia coli isolated from farmers and farmed chickens in Tunisia and Nigeria.

The poultry industry is a very important agricultural and industrial sector in Tunisia and Nigeria, with little information about occurrence of diarrheagenic Escherichia coli in the farmers and chickens. This study aimed to detect the prevalence of diarrheal E. coli in humans and poultry and to investigate plasmid-mediated quinolone resistance (PMQR) genes in both countries.
