Drug Resistance Detection of Escherichia Coli from Different Food Origins in Some Districts of Shaanxi Province
摘要
Abstract
Antibiotic resistance and prevalence of Shiga Toxin-producing Escherichia coli were determined among Escherichia coli isolates collected from retail meats and ready-to-eat food in supermarkets and open markets in Xi'an and Yangling areas of Shaanxi Province. Antimicrobial Susceptibility to 15 antibiotics of 748 Escherichia coli isolates were determined by using agar dilution methods, which was recommended by National Committee of Clinical Laboratory Standard(NCCLS), and using E.coli. ATCC25922, E. faecalis ATCC29212, Staphylococcus Aureus ATCC25923 as quality control strains. The results indicated that the isolates were most resistant to streptomycin at 88.2%, followed by resistance to tetracycline (84.4%),trimethoprim-suffamethoxazole (64.4%), nalidixic acid (62.6%), ampicillin (56.0%),ciprofloxacin (39.2%), chloramphenicol (37.6%), kanamycin (34.9%), gentamicin (34.2% ), amoxicillin-clavulanic acid (28.9%),gatifloxacin(26.9%). The isolates displayed lower resistance to amikacin (8.3%), cefoxitin (11.5%), ceftriaxone(13.8%),cefoperazone (19.5%). 73.9% of the isolates were multidrug-resistant. Two Shiga Toxin-producing Escherichia coli isolates were isolated from pork and mutton samples. Escherichia coli isolates recovered from retail meats and ready-to-eat food in Xi'an district were seriously resistant to common antibiotics.关键词
