概括
拉各斯州的废水监测显示了流行肠道病原体,如大肠杆菌和沙门氏菌,以及Mycobacterium物种,突出了流行病的潜力. 这项研究为尼日利亚的公共卫生战略提供了关键数据.
科学领域:
- 环境微生物学环境微生物学
- 公共卫生监督是对公共卫生的监督.
- 传染病流行病学 传染病流行病学
背景情况:
- 基于废水的流行病学 (WBE) 为传染病监测提供了潜力,但尼日利亚缺乏可靠的数据.
- 这项研究通过评估拉各斯州废水中的病原体和抗菌素耐药性来解决数据缺口.
研究的目的:
- 评估废水道中临床相关的传染病原体的流行率.
- 为了确定孤立的细菌病原体的抗微生物耐药性概况.
- 为尼日利亚提供数据支持基于废水的流行病学.
主要方法:
- 在拉各斯州的20个地方政府区域 (LGA) 进行了40个废水运河的横截面调查.
- 使用文化分析和PCR检测细菌病原体,非结核性菌根菌和SARS-CoV-2.
- 社区流行病学调查使用问卷来评估暴露途径.
主要成果:
- 没有检测到SARS-CoV-2. 在15个LGA中确定了mycobacterium物种 (M. fortitium群,M. kansasii).
- 分离的关键肠道病原体包括大肠杆菌 (28.5%),沙门氏菌spp. (16.3%),Vibrio cholerae (10.6%) 和Shigella spp. 这三种菌种的发病率较高. 这是5.7%. (5.7%).
- 观察到扩展谱β-乳糖酶基因 (87.5%) 的高患病率,SHV和CTX-M在42.5%的道中被发现.
结论:
- 拉各斯州的废水运河藏着具有流行病潜力的病原体.
- 这些发现支持废水监测和处理战略的实施.
- 建议进行纵向研究,以追踪病原体负载和抗菌素耐药性趋势.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
01:26Principles of Disease Surveillance
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
01:30Microbial Wastewater Treatment
Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
