Wastewater treatment plants (WWTPs) are recognised as key hotspots for the dissemination of antimicrobial-resistant bacteria and antimicrobial resistance genes (ARGs). However, studies addressing role domestic WWTPs in spread traits tropical regions remain limited. This study evaluated a WWTP during dry rainy seasons to examine its reservoir hub ARGs potential bacterial pathogens. The demonstrated stable physicochemical removal efficiencies, although performance slightly decreased season. Notably, relative abundance measured by qPCR was higher effluent than influent WWTP. Metagenomic analysis activated sludge revealed that chromosomally encoded conferred macrolides, aminoglycosides, rifamycin, sulphonamides, tetracyclines. In contrast, plasmid-associated were primarily linked against quaternary ammonium compounds (QACs), indicating presence conjugative plasmid facilitating mobility persistence QAC within microbial community. Furthermore, pathobiome identified high pathogens, including genera Gordonia, Acidovorax, Pseudomonas, Mycobacterium members. These findings highlight reservoirs amplifiers environments.

The microbiota in wastewater treatment plants (WWTPs) and incoming is critical for the process, preservation of natural ecosystems human health, recovery resources achievement sustainability goals. Both core species conditionally rare abundant taxa (CRAT) are considered process-critical but little known about identity as well true functional ecological importance. Here, we present a comprehensive investigation 84 municipal activated sludge (AS) with nutrient removal treating ~ 70% all within confined geographical area, Denmark (43,000 km

Despite the emergence of antibiotic resistance genes (ARGs) and resistant bacteria (ARBs), how biological inter-trophic interactions, modulated by watershed urbanization, shape resistome remains unexplored. We collected water samples from highly urbanized (western: 65 % built land, sewage-affected) lesser-urbanized (northern: 25 drinking source) downstream tributaries Jiulong River in southeast China over dry wet seasons. utilized metagenomic amplicon (16S 18S rDNA) sequencing to investigate relationships among microeukaryotic algae, consumer protists, bacterial communities, resistome. Metagenomic results showed that ARG-MGE-carrying contigs (mobile ARGs), rather than ARG-carrying (non-mobile exhibited more pronounced discrepancies between tributaries. A higher total abundance ARGs a greater number co-shared pathogen non-pathogen were observed western tributary. Structural equation modeling revealed protist-bacteria algae-bacteria cohesions predominantly influenced northern tributaries, respectively. Additionally, protists had significant associations (511 out 634) with carrying mobile tributary, while algae (73 105) These highlight distinct driving factors urbanization.
