Resistome and virulome in aquatic environments from Brazil

The release of untreated domestic and hospital effluents into rivers leads to the transmission of infectious diseases and contamination with drug residues, including antimicrobials, which increase the selection of antimicrobial-resistant bacteria. For this investigation, water samples were collected from three different aquatic environments in the state of Sao Paulo, Brazil, and the microbial diversity, virulome, and resistome were evaluated and related to the Water Quality Index from each collection site.

未经处理的生活污水与医院废水排入河流后，会造成传染病传播以及包括抗菌药物在内的药物残留污染，进而加剧抗微生物耐药细菌的筛选与扩散。本研究从巴西圣保罗州的三种不同水生环境中采集水样，对其中的微生物多样性、毒力组（virulome）与耐药组（resistome）进行评估分析，并将上述结果与各采样点的水质指数（Water Quality Index）进行关联研究。
