title: Prevalence and antimicrobial resistance of Salmonella serotypes isolated from retail chicken meat and giblets in Iran.
abstract: BACKGROUND
  Salmonella is one of the major foodborne pathogens responsible for outbreaks of foodborne illness in humans worldwide.
  
  
  METHODS
  A total of 560 samples of chicken meat and giblets were collected from retail markets for Salmonella identification, serotyping, and antimicrobial resistance testing.
  
  
  RESULTS
  Salmonella was detected in 19.8% of samples. Among the five serotypes identified, S. Thompson was the predominant type (48.7%). High antimicrobial resistance rates were observed to nalidixic acid (92.8%), tetracycline (81%), trimethoprim (68.4%), sulfamethoxazole / trimethoprim (61.2%), streptomycin (56.7%), and kanamycin (36.9%). Although resistance to chloramphenicol (3.6%), amoxicillin-clavulanic acid (5.4%), and ampicillin (11.7%) was detected, none of the isolates were resistant to ceftazidime, ceftriaxone, cefotaxime, ciprofloxacin, colistin, gentamicin, nor imipenem.
  
  
  CONCLUSIONS
  Restrictions on the irrational use of antibiotics in humans and animals are suggested for the reduction of resistant strains.
