概括
废水监测显示社区规模,而不是抗菌剂的使用,驱动抗菌素耐药性基因水平. 医院的废水显示出更高的抗菌剂度,但耐药性基因水平与社区的废水相当,这表明特有AMR的发展.
科学领域:
- 环境微生物学环境微生物学
- 公共卫生 公共卫生
- 废水流行病学 废水流行病学
背景情况:
- 抗菌剂 (AAs) 和相应的耐药基因 (ARGs) 是关键的公共卫生问题.
- 废水监测提供了关于社区一级AA使用和ARG流行情况的见解.
- 了解ARG扩散的驱动因素对于有效的抗菌药物管理至关重要.
研究的目的:
- 调查社区废水中抗菌剂负载和抗菌素耐药性基因流行之间的相关性.
- 为了比较医院和社区废水中的AA和ARG配置文件.
- 确定影响城市废水中ARG水平的关键因素.
主要方法:
- 在13个月的时间里,从一个城市 (>100k人) 的社区废水的纵向监测.
- 量化各种抗菌剂及其相应的耐药基因.
- 来自社区和医院环境的废水样本的比较.
主要成果:
- 抗菌剂水平显示季节性波动,而ARG患病率变化较小.
- 在季节性AA使用期间,观察到特定AA和ARG之间的正相关性.
- 对微生物规范化的ARG负载与人口规模成比例,表明社区规模是ARG水平的主要驱动因素.
- 与社区废水相比,医院的废水中含有许多AA的度更高,但ARG度相当.
- 几个AA在医院和社区废水中都超过了预测的无效度 (PNEC).
结论:
- 社区规模,而不是抗微生物剂水平的波动,似乎是污水中抗微生物药物耐药性基因丰富的主要驱动因素.
- 抗微生物药物耐药性水平可能是特有的,随着时间的推移在社区内发展.
- 医院是抗微生物药物的重要来源,由于潜在的高风险,医院在抗微生物耐药性监测中需要考虑.

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...

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...

Gene Regulation in Microbial Communities: Quorum Sensing
50
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
