The antibiotic resistance in Salmonella isolates from 400 imported chicken carcasses in Bhutan and from 178 pig carcasses in Vietnam were analyzed on a random basis against 14 antimicrobial agents. Among the poultry samples tested, 13% were positive for Salmonella. Salmonella Enteritidis dominated with a prevalence of 80.7%, and 40 of the 42 isolates harbored two or more resistance determinants. For the 178 pigs investigated, 49.4% of the swabs and 34.8% of the lymph nodes were Salmonella positive. The most prevalent serotypes in lymph nodes were Salmonella Derby (50.0%) and Salmonella Typhimurium (27.4%). From the Salmonella isolates from pigs, only 6% were sensitive to the antimicrobial agents tested. The high resistance level of Salmonella isolates from pigs and chicken carcasses to different classes of antimicrobials should be emphasized and encourage a prudent use of these agents in animal farming, especially in pig production.
对 400 批来自不丹进口鸡肉和 178 批来自越南猪肉中的 400 个沙门氏菌分离株进行了随机分析，以对抗生素进行了 14 种药物敏感性测试。在所测试的家禽样本中，13%的样本呈沙门氏菌阳性。肠炎沙门氏菌占主导地位，流行率为 80.7%，42 株分离株中有 40 株携带两种或两种以上的耐药决定因子。在调查的 178 头猪中，49.4%的拭子和 34.8%的淋巴结呈沙门氏菌阳性。在淋巴结中最常见的血清型是德比沙门氏菌（50.0%）和鼠伤寒沙门氏菌（27.4%）。从猪分离的沙门氏菌中，只有 6%对测试的抗生素敏感。来自猪和鸡肉中的沙门氏菌分离株对不同类别的抗生素具有高度耐药性，这一点应引起重视，并鼓励在动物养殖中谨慎使用这些药物，尤其是在猪生产中。
