Summary: The study investigated the antimicrobial resistome in wastewater treatment plants using shotgun metagenomic analysis. The results showed that there were two locations where the transition of the resistome occurred during wastewater treatment, resulting in a distinctive resistome in influent wastewater, activated sludge, and treated effluent. The resistome in influent wastewater was characterized by a high abundance of antibiotic resistance genes (ARGs) on clinically important drugs, while sludge retained a higher abundance of multidrug ARGs associated with efflux pump. Seasonality was the primary factor affecting the resistome in influent wastewater, which partially influenced the subsequent resistome of activated sludge and treated effluent. Importantly, some ARGs on clinically important drugs in influent wastewater passed through the biological treatment to be discharged in the treated effluent, except in the membrane bioreactor process.

Summary: Pathogenic Escherichia coli can be classified into specific variants (pathovars) based on their behavior and the expression of specific virulence factors. These pathogens interact with CEACAMs through both core elements common to all E. coli and pathovar-specific virulence traits that target the IgV regions of CEACAMs. Recent data suggests that these interactions may not only benefit the pathogen but also provide a mechanism for pathogen elimination.

Summary: This study found that DW-EC bacteriophage isolated from Indonesian traditional food has inhibitory and destructive effects on the biofilms of pathogenic E. coli, and its activity is significantly higher than that against B. cereus. This indicates that DW-EC bacteriophage has the potential to be used as an anti-biofilm candidate for polystyrene and stainless steel equipment in the food industry.

Summary: This study investigated the effects of ygeK on biofilm formation and environmental stress resistance in Avian pathogenic Escherichia coli (APEC). The multi-level regulation of ygeK in APEC and associations between differentially expressed proteins and key ygeK targets were also analyzed. This research provides new insights into the pathogenicity of APEC and can contribute to the development of disease prevention and treatment strategies.

Summary: This study conducted a Monte Carlo simulation-based QMRA case study on workers exposed to bioaerosols in two WWTPs, finding that exposure to S. aureus or E. coli bioaerosols without personal protective equipment led to infection probabilities exceeding U.S. EPA benchmarks and disease burden not meeting WHO standards. However, using PPE effectively reduced annual infection health risks to acceptable levels. Sensitivity analysis showed that mechanical aeration modes in WWTPs had a significant impact on health risks, particularly in exposures with high concentration levels.

Summary: The study investigated the effects of environmental stress and nutrient conditions on biofilm formation of avian pathogenic Escherichia coli (APEC). The results showed that biofilm formation ability of the APEC strain DE17 varied under different temperatures and nutrient conditions. The transcription levels of biofilm-related genes in DE17 were also affected by environmental and nutrient factors.

Summary: Reuse of alternative water sources for irrigation is a sustainable approach to reduce water gaps and increase food production, but it poses a risk of bacterial contamination. This study developed a statistical machine-learning framework to accurately predict the concentration of pathogenic organisms, such as E. coli, in untreated surface water using an impedimetric electrochemical aptasensor. The framework improved prediction accuracy and can be used for rapid decision support in hydroponic irrigation.

Summary: This study analyzed the distribution and polluted loading of six typical ASs in wastewater treatment plants (WWTPs) and receiving waters near the coast of Shenzhen city, China. The results showed elevated levels of ASs in WWTPs located near highly populated areas, with sucralose being the predominant component.

Summary: Escherichia coli are versatile microorganisms found in the normal intestinal microbiota of humans and animals. They can become emerging human pathogens by acquiring genes encoding virulence factors. Nine enteric E. coli pathotypes have been characterized, utilizing various virulence factors to cause intestinal and extraintestinal diseases.

Summary: The concentration levels of nine perfluoroalkyl substances (PFAS) in Romanian wastewater treatment plants (WWTPs) and their transfer to natural receivers were determined in this study. Most of the wastewater samples contained perfluoropentanoic acid (PFPeA), perfluorooctanoic acid (PFOA), and perfluorooctansulfonate acid (PFOS). PFOA and PFOS were also found in sewage sludge samples. The daily input and discharge of PFOA and PFOS in the WWTPs were estimated. Human and environmental risk assessments showed that PFOA and PFOS pose risks to different age and gender categories, with children being the most exposed to contamination.

Summary: APEC is the responsible pathogen for colibacillosis in poultry, and the role of YgeK in APEC has not been reported. This study found that YgeK plays a crucial role in APEC virulence by affecting flagellar formation, bacterial motility, serum sensitivity, and adhesion ability. The results contribute to understanding the function of the ETT2 cluster in APEC and clarify its pathogenic mechanism.
