The aim of this study was to examine the relationship between antibiotic resistance patterns among Salmonella enterica subsp. enterica Serovar Enteritidis isolates (Salmonella Enteritidis) of human and poultry origin. Antibiotic resistance of 97 Salmonella Enteritidis isolates from 25 chicken meat, 25 chicken intestine and 47 human fecal samples was examined using the National Committee for Clinical Laboratory Standards (NCCLS, 1997) disk diffusion method. Resistance patterns of the isolates were as follows: Of the 25 chicken meat isolates 4 were resistant to some antibiotics. Two isolates (CM15 and CM22) were resistant to ampicillin (AMP), cefuroxime sodium (CXM), ceftriaxone (CRO), trimethoprim-sulphamethazole (SXT) and ampicillin-sulbactam (SAM). Of the other 2 isolates, CM20 showed resistance to ceftriaxone (CRO) and CM23 was resistant to chloromphenicol (C) and cephalexime (CL). Eight human isolates showed 4 different resistance patterns. Five (HF3, HF19, HF20, HF22, and HF25) were resistant to ampicillin (AMP), ampicillin-sulbactam (SAM), tetracycline (TE) and chloromphenicol (C), while resistance to chloromphenicol (C) and cephalexime (CL) was observed in HF32 and HF46. HF13 was resistant to both ampicillin (AMP) and ampicillin-sulbactam (SAM). One of the chicken intestinal isolates was found to be resistant only to cefuroxime sodium (CXM). There was no relationship between antibiotic resistance patterns for Salmonella isolates of different origins. Multiple antibiotic resistance patterns were observed in some isolates. It is important that some isolates of chicken intestine and meat origin showed resistance to antibiotics being used in humans.
