Summary: The misuse of antibiotics leads to increased resistance in bacteria, and ballast water serves as a carrier for global dissemination of antibiotic resistance genes (ARGs). Investigating and controlling the presence of ARGs in ballast water is crucial. This review summarizes the distribution and abundance of ARGs in ballast water from different sea areas, and analyzes the factors influencing ARGs distribution. Additionally, it reviews the impact of disinfection technologies on ARGs transfer in ballast water.

Summary: Wanfeng Lake in China has been heavily impacted by aquaculture and human activities, resulting in the accumulation of antibiotics and antibiotic resistance genes (ARGs). This study examined the presence of antibiotics, ARGs, mobile genetic elements, and microbial community structure in the lake. The results showed high concentrations of antibiotics in both surface water and sediments, with ofloxacin (OFX) and flumequine (FLU) being the most prevalent. The dominance of sulfonamide resistance genes in both water and sediments was observed. The study also identified the main microorganisms present in the sediment. Furthermore, a positive correlation was found between antibiotics, ARGs, and both environmental factors and microorganisms. These findings highlight the potential threats posed by antibiotics and ARGs in Wanfeng Lake, providing a basis for future research.

Summary: This study investigated the molecular mechanisms of phylogenetic turnover in microbial communities and the impact of antibiotics and antibiotic resistance genes (ARGs) on microbial assemblages. The research found that increased concentrations of antibiotics in ecosystems can stimulate the proliferation of ARGs, potentially affecting the assembly of microbial communities. Additionally, the study revealed complex interrelationships between ARGs and microbial communities, with arthropods and nematodes showing the strongest potential for acquiring ARGs.

Summary: The study aimed to evaluate the community-wide antimicrobial resistance (AMR) profile of an urban setting using the culture-independent wastewater-based epidemiological surveillance (WBE) approach. The domestic wastewater sample was collected at the converging point of the drain connecting the Sewage Treatment Plant (STP). The collected water sample was evaluated for the presence of 125 antibiotic resistance genes (ARGs) and 13 mobile genetic elements (MGEs, 5 integrons and 8 transposons). Antibiotic residues and the composition of bacterial communities were also examined. The study provided comprehensive baseline information of ARGs on a community scale and will be of use for ARG prevention and management.

Summary: The responses of anammox consortia to antibiotics SDZ and CTC were evaluated in terms of general performance, microbial activity, diversity and abundance of antibiotic resistance genes (ARGs). The results showed that the consortia had great resistance to SDZ but were heavily affected by CTC. The presence of ARGs, particularly in Ca. Brocadia bacteria, played a significant role in the resistance mechanism.

Summary: While river restoration activities improved water quality indicators, such as total phosphorus content, the concentrations of antibiotics in river water increased after restoration, likely due to increased antibiotic usage for COVID-19 treatment in 2020. The spatial distributions of antibiotics were less varied after restoration, and the correlations between microbial communities, antibiotic resistant genes, and physicochemical changes were observed.

Summary: This study assessed the risk of antibiotic resistance gene (ARGs) transmission in microbial electrolysis cells (MECs) and explored the mechanisms of ARG transfer under different voltage conditions. The results showed that voltage and donor cell number significantly influenced the frequency of ARG transfer, and high voltage increased the production of reactive oxygen species and cell membrane permeability.

Summary: This study investigated the occurrence of pathogens, antibiotic resistance genes (ARGs), and bacterial communities in UV/chlorine-treated reclaimed water samples. The results showed that UV/chlorine treatment effectively reduced the numbers of pathogens and changed the bacterial community structure. Additionally, the treatment decreased the abundance of ARGs and mobile genetic elements (MGEs). However, certain ARGs and MGEs were consistently detected across different seasons, indicating the need for attention.

Summary: The presence of microplastics in wastewater alters the abundance and functions of microorganisms, as well as the distribution and removal of antibiotic resistance genes (ARGs). The microbial community and ARGs are affected differently by the presence of microplastics. Certain concentrations of microplastics can enhance the ability of specific types of ARGs during ultraviolet disinfection. PSMPs change the content of microbial phyla and shift microbial functions. They also alter the content of ARGs, increasing some ARGs while decreasing others. PSMPs decrease the free ARG content in wastewater and intervene the efficiency of UV disinfection. Overall, the presence of PSMPs alters the distribution and removal of microbial community and ARGs, highlighting the combined risks.

Summary: This study found that under high levels of ammonium, aerobic granular sludge (AGS) showed good removal efficiency for three fluoroquinolones (FQs), with ciprofloxacin (CFX) and norfloxacin (NFX) being more effectively removed. Antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) related to FQs tended to exist in denitrifying bacteria, indicating a preference for denitrifiers in the distribution of these elements.

Summary: Municipal sewage sludge and other biosolids have high potential as organic fertilizers in agriculture, but their use is limited by the presence of heavy metal and organic compound pollutants. This study investigated the impact of stabilization method and wastewater treatment plant size on microbial community structure and gene abundance, finding antibiotic resistance genes and mobile genetic elements in all samples. The presence of certain heavy metals correlated with the presence of antibiotic resistance genes. It is important to assess pollutants and long-term effects before considering the use of sewage sludge as fertilizer.

Summary: Antibiotic resistance is a major threat to public health, and landscaped fish ponds created by urbanization provide a favorable environment for the generation and spread of antibiotic-resistant genes and bacteria. This study investigated the effects of specific antibiotics (tetracycline and ciprofloxacin) on the microbial community in water samples from a landscape pond. The results showed that the administration of antibiotics influenced the microbial community structure and increased the abundance of antibiotic-resistant genes.

Summary: The risk from environmental pollution caused by chloramphenicol (CAP) has become a serious global concern, especially for antibiotic resistance microorganisms co-exposed to CAP and salts. This study used a multistage contact oxidation reactor (MCOR) to treat CAP wastewater under the co-existence of CAP and salinity. The results showed that the co-existence of CAP and salinity promoted the enrichment of core genera Trichococcus and Lactococcus, but also inhibited the proliferation of antibiotic resistance genes (ARGs).

Summary: This study evaluated the effects of tetracycline and sulfamethoxazole on antibiotic resistance genes in the sewer system and revealed the mechanisms behind their proliferation. The results showed that ARGs proliferation was associated with horizontal gene transfer, increased secretion of extracellular polymeric substances, and the microbial community structure and diversity.
