Bacterial resistome in different stages of wastewater treatment plant is highly impacted by the abundance of the Pseudomonadota community

The study of bacterial communities and antibiotic-resistance genes in wastewater treatment plants (WWTPs) in the UAE reveals high levels of extended-spectrum beta-lactamase bacteria in the returned activated sludge stage, and the highest bacterial richness in the primary effluent stage. The findings highlight the potential of certain bacteria in AMR development and dissemination.
