ABSTRACT The objective of the research was to quantify three antibiotic resistance genes (tetQ, cfxA and mefA) in the faeces of dairy cows following therapeutic and prophylactic antibiotic treatments. Manure collected from dairy cows treated with either no antibiotic, pirlimycin hydrochloride (PIRL), ceftiofur crystalline free acid (CCFA) or cephapirin benzathine (CEPH) were submitted to quantitative PCR analysis. No treatment effects on the abundance of the tetQ and cfxA were observed. There was a trend for the abundance of the mefA to be increased in cows treated with PIRL (P = 0.07). Overall, the results showed no difference of measured three ARGs from cows receiving different antibiotics. Considering the limited scope of our investigation, further investigation is needed to provide more information on ARGs excretion from cows that received therapeutic and prophylactic antibiotic treatment.

短期治疗性和预防性抗生素给药后奶牛粪便中的抗生素抗性基因

摘要 本研究的目的是量化奶牛粪便中的三种抗生素抗性基因(tetQ、cfxA 和 mefA)。从未经抗生素、盐酸吡利霉素 (PIRL)、头孢噻呋结晶游离酸 (CCFA) 或头孢匹林苄星 (CEPH) 处理的奶牛收集的粪便进行定量 PCR 分析。没有观察到对 tetQ 和 cfxA 丰度的处理影响。在用 PIRL 治疗的奶牛中,mefA 的丰度有增加的趋势(P = 0.07)。总体而言,结果显示来自接受不同抗生素的奶牛测量的三种 ARG 没有差异。考虑到我们调查的范围有限,
