The floods of 2018 caused havoc in the State of Kerala, situated in the extreme south‐west of India, in terms of infrastructure and health. This research article provides the first‐ever assessment of the bacterial diversity and its antibiotic susceptibility of the inundated areas of Pampa, Periyar and Vembanad waterbodies by comparing the data collected in two different time intervals succeeding the calamitous floods that is, immediately after flood and 5 months post‐flood. An elevated total coliform count was detected in the waterbodies after the flood thereby rendering it unsafe for drinking. Variation in bacterial diversity was observed in the river and lake water samples with a distinct increase in that of the river samples immediately after flood indicated by shannon diversity index (>5.5). Resistance to ampicillin and cefotaxime was observed in a major proportion of isolates from the three biotopes thus indicating the influence of antibiotic wastes accumulated from different sources of human interventions. Furthermore, operational taxonomic units clustering to Acinetobacter, Legionella, Pseudomonas and Burkholderia genera were detected by metataxonomic analysis which portray as a potential health risk in the future. The article emphasises the importance of adopting sanitation programmes for effective management of epidemic outbreaks post floods.

使用受洪水影响的水体中微生物的生物分类学和抗生素耐药性概况阐明健康风险，喀拉拉邦2018

就基础设施和健康而言，2018年的洪灾在印度西南偏远的喀拉拉邦造成了严重破坏。这篇研究文章通过比较在洪灾发生后立即发生的两次和洪灾之后的两个不同时间间隔内收集的数据，首次评估了潘帕，佩里亚尔和文巴纳德水域淹没区的细菌多样性及其对抗生素的敏感性。洪水后数月。洪水后在水体中检测到大肠菌群总数增加，因此不安全饮用。在河水和湖泊水样中观察到细菌多样性的变化，洪灾发生后，香农多样性指数（> 5.5）表明河流样本中细菌的多样性明显增加。在来自这三个生物群落的大部分分离物中观察到了对氨苄西林和头孢噻肟的耐药性，从而表明了从不同的人类干预源中积累的抗生素废物的影响。此外，业务分类单位聚类为通过元分类学分析检测到不动杆菌属，军团菌属，假单胞菌属和伯克霍尔德氏菌属，它们被描绘为未来的潜在健康风险。文章强调了采取卫生计划以有效管理洪灾后流行病暴发的重要性。
