概括
在 brojler中使用ENROFLOXACIN可降低沙门氏菌的发病率,但可增加大肠杆菌和沙门氏菌的抗菌耐药性. 它没有影响坎皮洛巴克特的流行或耐药性,这表明共选择效应.
科学领域:
- 兽医微生物学 兽医微生物学
- 抗微生物耐药性 抗微生物耐药性
- 食品安全 食品安全
背景情况:
- 恩洛夫洛克萨 (ENR) 是家禽生产中广泛使用的诺类抗生素.
- 了解ENR对肠道细菌种群及其耐药性概况的影响对于公共卫生至关重要.
- 肉可以携带各种细菌,包括致病性大肠杆菌,沙门氏菌和坎比洛巴克.
研究的目的:
- 调查恩罗夫洛克萨给药对肉中大肠杆菌,沙门氏菌和坎比洛巴克特菌的流行程度的影响.
- 评估恩罗夫洛克萨对这些细菌在野外条件下的抗菌素耐药性模式的影响.
- 为了确定是否使用恩罗夫洛克萨会影响对其他抗菌剂耐药性的共同选择.
主要方法:
- 现场研究涉及肉养殖场,使用和不使用恩洛夫洛克萨.
- 从便样本中分离和识别大肠杆菌,沙门氏菌和坎比洛巴克.
- 单独的细菌对恩罗夫洛克萨和其他相关抗生素的抗菌敏感性测试.
主要成果:
- 在使用ENR (6.4%) 的农场,沙门氏菌隔离率明显低于非ENR农场 (11.6%).
- 在ENR农场 (6.7%) 与非ENR农场 (3.3%) 的隔离率明显高.
- 在经ENR处理的农场的大肠杆菌和沙门氏菌中观察到对ENR,安培西林,氨基醇,四环素和三甲/硫甲醇的显著更高的耐药性.
结论:
- 在肉养殖场中使用恩罗夫洛克萨可以降低沙门氏菌的流行率,但不能降低坎皮洛巴克.
- 恩洛夫洛克萨的使用显著增加了大肠杆菌和沙门氏菌的抗菌耐药性,但不是坎比洛巴克.
- 暴露于恩洛夫洛克萨可能会产生同选择性压力,在野外环境中促进肠道细菌对多种抗生素的耐药性.

Antimicrobial Effectiveness
98
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Development of Antibiotic Resistance
48
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
