antibiotic resistance of faecal enterococci in domestic poultry and broilers from commercial farms

The aim of this study was to determine the prevalence and antibiotic resistance of enterococci isolated from domestic poultry, laying hens from ecological farm and broilers from commercial farms. Susceptibilities of isolated enterococci were tested using the disk diffusion method. All isolates showed some degree of multiple antibiotic resistances. The resistance to compound sulphonamides (91.891%), tetracycline (51.351%) and streptomycin (37.837%) was the most frequent. Of all isolates of Enterococcus strains 83.783% were susceptible to enrofloxacin. The susceptibility of isolates from broilers and laying hens from ecology farm to enrofloxacin were significantly higher (P<0.05) than in isolates from domestic poultry. Between the others data were not significant differences.
