Special Issue Information

Dear Colleagues,

This Special Issue considers surface freshwater and groundwater as equally important parts of the same overall resource, with the goal being to integrate inter- and transdisciplinary research on freshwater quality under changing climate scenarios where droughts are becoming more frequent and severe. The increasing scarcity of precipitation is leading to decreased water levels and water quality in surface and groundwater bodies, leading to environmental, societal, political and economic changes that can affect global health. In lentic water bodies, droughts and warmer temperatures promote the occurrence of life-threatening events within local communities. Groundwater quality may be also greatly affected, namely in coastal regions where freshwater salinization may occur. Therefore, the preservation of freshwater quality is a crucial and urgent issue to resolve. In the era of the “knowledge-based” society, information is vital to increasing understanding and awareness on the impacts of climate change and to prepare society to find and implement ways to deal with those changes through collaborative solutions (with stakeholders, academia and policy makers).

Within the context of climate change, and geographically focusing on the Southern Europe regions, we welcome research papers and reviews regarding current topics on freshwater ecology, toxicity, hydrochemistry, monitoring approaches, but also societal aspects related to these concerning climate challenges. Ultimately, this Special Issue intends to establish a multidisciplinary standpoint in regard to how best to tackle freshwater quality issues.

This study investigates the prevalence of resistance and virulence genes in Klebsiella isolates from surface waters in Northern Portugal, within the broader context of freshwater quality challenges in Southern Europe. The aim of this research is to explain how Klebsiella dynamics, antibiotic resistance, and biofilm formation interact in surface waters. Antimicrobial susceptibility was examined using the Kirby–Bauer disk diffusion method against 11 antibiotics and screening for Extended-Spectrum Beta-Lactamase (ESBL) production using the double-disk synergy. PCR was employed to detect resistance and virulence genes, while biofilm production was assessed using the microplate method. Out of 77 water isolates, 33 Klebsiella (14 Klebsiella spp. and 19 K. pneumoniae strains) were isolated. ESBL production was observed in 36.8% of K. pneumoniae and 28.6% of Klebsiella spp. High resistance rates to blaCTX-U were observed in both. The papC gene was prevalent, signifying potential environmental risks. Biofilm production averaged 81.3% for K. pneumoniae and 86.9% for Klebsiella spp. These findings underscore the intricate interplay between Klebsiella’s dynamics and freshwater quality, with ESBL’s prevalence raising concerns about waterborne dissemination and public health implications. This work supports the need for vigilance of Klebsiella in surface waters in Southern Europe. Full article
