Summary: The study identified and tested bacterial strains entering and leaving a hospital wastewater treatment plant to determine the level of antibiotic resistance. The results showed higher numbers of antibiotic resistant bacteria in the sludge compared to the inlet wastewater. The study suggests monitoring of outlet water and sludge and adopting efficient treatment methods for hospital waste to prevent the release of resistant bacterial strains into the environment.

Summary: This study investigated the effectiveness of photocatalysis in purifying hospital wastewater, and found that it can effectively remove pharmaceutical residues and pathogenic bacteria, as well as alter the antibiotic resistance of surviving bacteria. However, considerable concentrations of antibiotic-resistant genes were still present in the effluents, which may contribute to antibiotic resistance in aquatic bacterial communities.

Summary: Antibiotic resistant bacteria (ARB) are a significant health risk that is primarily caused by human activities. Bacteria can acquire antibiotic resistance even before the discovery of antibiotics, and this resistance can spread through various routes. Bacteriophages play a crucial role in disseminating antibiotic resistance genes (ARGs) in the environment. This study investigated seven ARGs in raw urban and hospital wastewaters, with higher frequencies of bla genes detected in the phage DNA fraction. The study also revealed the presence of the resistance gene to colistin (mcr-1) in these wastewaters, highlighting the potential implications for public health.

Summary: Although urban wastewater treatment plants play a crucial role in eliminating antibiotic resistance, they still struggle to produce effluents free of resistance. UV-C radiation significantly reduces the abundance and prevalence of carbapenem-resistant bacteria (CRB), but CRB numbers increased after incubation in the dark. Carbapenem-resistant Enterobacteriaceae (CRE) with bla(GES-5), integrons, and plasmids were detected in samples, raising concerns about potential horizontal gene transfer within these systems. Surveillance of carbapenem resistance in UWWTPs is essential for timely mitigation measures.

Summary: This study investigated the extent of resistance to 'last-resort' antibiotics in hospital wastewater. The findings revealed high levels of resistance and prevalent multiple resistance to antibiotics, including 'last-resort' antibiotics. The study also discovered inconsistencies between resistance phenotypes and genotypes, as well as the first occurrence of tet(X4)-containing tigecycline-resistant Gram-positive pathogens. Furthermore, the wastewater treatment processes were effective in preventing the release of 'last -resort' antibiotic resistant pathogens.

Summary: Surface runoff is a main pathway for emerging pollutants, including antibiotics, antibiotic-resistant bacteria, and antibiotic resistance genes, to enter marine sediments. This study investigates the impact of emerging pollutants on the fate of antibiotic resistance genes in marine sediments from different seas in China. The results show that antibiotic exposure generally decreases the relative abundance of most antibiotic resistance genes, but there are exceptions with increased abundance observed in certain conditions. The findings suggest that dosing with emerging pollutants does not increase antibiotic resistance gene abundance in marine sediments.

Summary: Wastewater from hospitals needs to be carefully monitored and treated to prevent the spread of harmful pollutants and drug-resistant bacteria. This study focuses on characterizing the properties of hospital wastewater before it is discharged into the environment, particularly the presence of multi-drug-resistant bacteria and the impact of wastewater reuse in agriculture.

Summary: The aim of this study was to investigate the survival and antimicrobial resistance adaptation of emerging antibiotic-resistant bacteria (ARB) in a wastewater treatment process in Thailand. The results showed that various ARBs, including resistant strains of E. coli, coliforms, and Acinetobacter spp. as well as MRSA and VRE, were present in both domestic and hospital wastewater. However, the percentages of carbapenem resistance and ESBL resistance were higher in hospital wastewater. The study also found that some ARBs could survive and reproduce in the treatment process, particularly in the chlorinated effluent.

Summary: This study discusses the occurrence and proliferation of antibiotic resistance in wastewater treatment plants, the factors influencing antibiotic resistance bacteria and genes, the tools to assess antibiotic resistance, the environmental contamination of antibiotic resistant bacteria and genes from wastewater treatment plants, the effects on human health, and treatment strategies. Resistant bacteria such as Enterobacteriaceae, Pseudomonas aeruginosa, and Escherichia coli exist in various processes of wastewater treatment plants due to the high concentration of antibiotics in wastewater. Improving wastewater treatment technology and avoiding antibiotic misuse are critical to overcome the threat of antibiotic resistance. Factors such as abiotic factors and organic loads can affect the development of antibiotic resistance bacteria and genes in wastewater treatment plants. Molecular methods such as DNA sequencing and real-time PCR can be used for rapid characterization and detection of antibiotic resistance bacteria and genes. Reusing wastewater effluent for irrigation is an efficient method to overcome water scarcity, but it may also pose potential environmental risks such as increased antibiotic resistance in soil microbiome. Treatment technologies like anaerobic and aerobic treatment, coagulation, membrane bioreactors, and disinfection are considered potential techniques to restrict antibiotic resistance in the environment.

Summary: The study investigated the advanced treatment of secondary effluent from an antibiotic wastewater treatment plant using ionizing radiation alone and combined with peroxymonosulfate (PMS)/H2O2 oxidation. Results showed that radiation could greatly reduce the content of antibiotics and antimicrobial resistance genes (ARGs), while the addition of PMS was better than H2O2 in enhancing the removal efficiency. Higher doses of radiation stimulated bacterial activity but damaged genes coding for cellular and genetic information processing. The ecological risk mainly came from erythromycin (ERY) and tetracycline (TC), which could be reduced to medium and low levels, respectively, after radiation.

Summary: This study investigates the presence and prevalence of antibiotic resistance genes (ARGs) in wastewater samples. The targeted analysis reveals high carriage of ARGs in wastewater, indicating potential release into the environment. The study also explores the relationship between bacterial composition and ARGs, suggesting possible bacterial hosts for these genes. The findings highlight the importance of understanding ARG contamination in wastewater and its potential impact on bacterial infections and treatment.

Summary: Ozone micron bubble (OMB) treatment effectively reduces Antibiotic Resistance Genes (ARGs) in infectious medical wastewater and mitigates the spread of drug resistance. Hospital wastewater contains high levels of antibiotic residues and ARGs, with a higher abundance of ARGs in the biological oxidation unit of wastewater treatment plants. OMB treatment shows better performance compared to ozone coarse bubble treatment and significantly reduces the accumulation of ARGs in hospital wastewater.

Summary: The diversity of both microorganisms and viruses in activated sludge of wastewater treatment plants plays a crucial role in controlling microbial dynamics and metabolisms. This study reveals the presence of unknown viral genera in activated sludge, indicating an unexplored reservoir for new viruses and viral diversity. The study also shows that viruses can enhance the performance of activated sludge by encoding auxiliary metabolic genes (AMGs) involved in biodegradation, but can also facilitate the spread of antibiotic resistance genes (ARGs) among microorganisms. Overall, this study highlights the mixed blessing of viruses in wastewater treatment plants and their impact on biochemical processes.
