In order to investigate the classification and antibiotic resistance of Salmonella species 718 isolates were isolated from patient in Seoul from 1996 to 2001. The two hundred and ninety eight isolates (41.5%) were identified as Sal. Enteritidis, followed by Sal. Typhi 218 isolates (30.4%), and Sal. Typhimurium 87 isolates (12.1%). The identified Salmonella species were most resistant to tetracycline (32.7%), followed by streptomycin (28.0%), ticarcillin (18.1%) and ampicillin (12.4%). Among isolates, 34.7% of Sal. Enteritidis were resistant to tetracycline, 32.3% to streptomycin, 23.2% to ticarcillin, 13.5% to ampicillin, respectively. 13.8% of Sal. Typhi were resistant to streptomycin, 10.6% to tetracycline, respectively. 66.7% of Sal. Typhimurium were resistant to tetracycline, 42.5% to streptomycin, 28.7% to ticarcillin, 26.4% to ampicillin and 17.2% to chloramphenicol, respectively. Of 718 isolates, 324 isolates (45.1%) were resistant to 1 or more drugs and 64 isolates (19.8%) were resistant to 1 drug, 132 isolates (40.7%) were resistant to 2 drugs, 50 isolates (15.4%) were resistant to 3 drugs, 27 isolates (8.3%) to 4 drugs, 27 isolates (8.3%) to 5 drugs, 22 isolates (6.8%) to 6 drugs. The most prevalent multiple resistant pattern was tetracycline-kanamycin (35.5%), followed by tetracycline-kanamycin-ticarcillin (8.3%), and tetracycline-kanamycin-ticarcillin-ampicillin (7.4%). Antibiotic resistant rate of Sal. Typhimurium was 73.6%, followed by Sal. Enteritidis 53.7% and Sal. Typhi 19.3%. Most Sal. Enteritidis was resistant to 1 drug or 2 drugs, whereas Sal. Typhi and Sal. Typhimurium were more resistant to 5 (16.7%) or 6 drugs (26.6%). The old generation antibiotics such as ampicillin, tetracycline, and streptomycin were annually more resistant than the new generation antibiotics such as ceftriaxone, ciprofloxacin or cefoxitin.
