We surveyed contamination in 110 pork samples from 12 fresh meat markets in Nongchok district, Bangkok, Thailand, and performed antimicrobial susceptibility testing with the disk diffusion method. The prevalence of . was 28.18%, and 52 strains were isolated. Antimicrobial susceptibility testing using the disk diffusion method revealed that 80.77% of the isolates were resistant to tetracycline and 76.92% to ampicillin. All strains were 100% susceptible to cloxacillin, cefoxitin, gentamicin, and cefazolin. The high percentage of antibiotic resistance to tetracycline and ampicillin was attributed to their use in treating infections in farmed animals and their addition to animal food for disease prevention. Interestingly, the present study revealed the intermediate resistance of . (13.46% of . -positive pork samples) to vancomycin which is a common medicine for treating severe infection in humans, suggesting that the trend of resistance might increase and becoming a serious problem of public health for both humans and animals.
我们对泰国曼谷农乔克区12个鲜肉市场的110份猪肉样本进行了污染调查，并采用纸片扩散法进行了药敏试验。……的流行率为28.18%，共分离出52株菌株。采用纸片扩散法进行的药敏试验显示，80.77%的分离株对四环素耐药，76.92%对氨苄西林耐药。所有菌株对氯唑西林、头孢西丁、庆大霉素和头孢唑林均100%敏感。对四环素和氨苄西林的高耐药率归因于它们用于治疗养殖动物的感染以及添加到动物饲料中用于疾病预防。有趣的是，本研究揭示了……（13.46%的……阳性猪肉样本）对万古霉素呈中度耐药，万古霉素是治疗人类严重感染的常用药物，这表明耐药趋势可能会增加，并成为人类和动物公共卫生的严重问题。
