The incidence and antimicrobial resistance of species in animal and poultry meat samples at slaughterhouses in Iran.

BACKGROUND AND OBJECTIVES

species are food-borne and zoonotic enteropathogens. Defined breakpoints for the investigation of antimicrobial resistance of are missing.

MATERIALS AND METHODS

The study was performed to investigate the incidence and antimicrobial resistance of species in animals and poultry meat samples procured from slaughterhouses in Iran. To investigate the prevalence of antimicrobial resistance, samples were collected from cattle (n=100), sheep (n=100), goat (n=100), broiler chicken (n=100), turkey (n=100) and quail (n=100). isolates of meat samples were isolated, investigated by PCR method and antibiotic resistance was also investigated. The susceptibility was assessed by Kirby-Bauer disc diffusion.

RESULTS

The results showed that 52 samples (8.66%) were positive for spp. The most prevalence were observed in broiler chickens (26%, n=26 samples), quail (13%, n=13 samples), turkey (8%, n=8), cattle (3%, n=3), sheep (1%, n=1) and goat (1%, n=1). had highest prevalence among species. All the isolates showed sensitivity to gentamicin, streptomycin and tetracycline.

CONCLUSION

Poultry meat is a potential source of infection with that must be considered in slaughterhouses in Iran. species showed sensitivity for a broad spectrum of antibiotics that can be used during infection with species.
