“…Fe(VI) has been shown to decrease the concentration of various organic molecules including antibiotics in water. − Studies have been conducted to determine the removal efficiency of antibiotics by Fe(VI) in the presence of different cations, anions, and organic constituents. − For example, we have studied the influence of inorganic constituents, e.g., chloride, ammonia, and carbonate, and organic components, such as creatine, hippuric acid, and creatinine of urine, in our previous studies. ,, We found that ammonia, carbonate, and creatinine enhanced the oxidation of antibiotics by Fe(VI). A few other studies have examined the removal of antibiotics by Fe(VI) in the presence of NOM ,, and reported the inhibitory effects of NOM in the removal of micropollutants in water. However, in our study, we observed an enhancing effect of NOM on the Fe(VI) induced abatement of the selected antibiotics trimethoprim and sulfamethoxazole, which are commonly found in contaminated surface water and wastewater.…”

The increasing presence of antibiotics in water sources threatens public health and ecosystems. Various treatments have been previously applied to degrade antibiotics, yet their efficiency is commonly hindered by the presence of natural organic matter (NOM) in water. On the contrary, we show here that nine types of NOM and NOM model compounds improved the removal of trimethoprim and sulfamethoxazole by ferrate(VI) (FeVIO4 2–, Fe(VI)) under mild alkaline conditions. This is probably associated with the presence of phenolic moieties in NOMs, as suggested by first-order kinetics using NOM, phenol, and hydroquinone. Electron paramagnetic resonance reveals that NOM radicals are generated within milliseconds in the Fe(VI)–NOM system via single-electron transfer from NOM to Fe(VI) with the formation of Fe(V). The dominance of the Fe(V) reaction with antibiotics resulted in their enhanced removal despite concurrent reactions between Fe(V) and NOM moieties, the radicals, and water. Kinetic modeling considering Fe(V) explains the enhanced kinetics of antibiotics abatement at low phenol concentrations. Experiments with humic and fulvic acids of lake and river waters show similar results, thus supporting the enhanced abatement of antibiotics in real water situations.

“…Consistent with previous studies, these results indicated the persistence of ARGs in aquaculture environments. (Shen et al, 2020;Suyamud et al, 2021). The high abundance of sulfonamide, tetracycline, quinolone, and phenicol resistance genes suggests that these bacteria may confer resistance to the most commonly used antibiotics in hybrid snakehead fish culture systems.…”

“…Despite the presence of various ARGs in aquaculture environments, microorganisms are considered the main vectors and determinants of ARG distribution and transmission (Wang et al, 2019). Antibiotic resistance genes mainly exist in bacterial genomes and may be transmitted through mobile genetic elements, including plasmids, integrons, transposons, and insertion sequences (Suyamud et al, 2021). Proteobacteria is the predominant phylum in Litopenaeus vannamei pond water, followed by Bacteroides (Zheng et al, 2016).…”

The increasing abundance of antibiotic resistance genes (ARGs), which are regarded as new pollutants, has raised public health concern. The use of antibiotics in aquaculture has promoted the evolution and spread of ARGs. The occurrence and abundance of ARGs in aquaculture has attracted extensive attention. However, the distribution and transmission of ARGs in aquaculture require further study. This study analyzed water and sediment from intensive culture of hybrid snakehead fish farm in Zhongshan, South China. Twenty-two types of ARGs were detected in all environmental samples. The relative abundance of sulfonamide resistance genes (sul1 and sul2) was the highest, ranging from 3.37×10-2 to 8.53×100 copies/16S rRNA gene. High occurrence of quinolones, phenicols, tetracycline resistance genes, and class 1 integrase gene (intI1) was also observed in pond water samples. This implies that pond water is one of the main reservoirs and origins of ARGs in the aquatic environment. Proteobacteria was the most abundant phylum in all the environmental samples, and its relative abundance ranged from 24.05% to 41.84%. Network and canonical correspondence analyses showed that a high abundance of ARGs (int1, sul1, sul2, qacEΔ1, aac6, and oqxA) was positively correlated with Proteobacteria, Cyanobacteria, and Bacteroidetes, and the abundance of Proteobacteria, Actinobacteria, and Patescibacteria was positively correlated with environmental factors (sulfide, nitrite nitrogen, pH, free chlorine, and ammonia nitrogen). These findings demonstrate the prevalence and persistence of ARGs in intensive fish farming in southern China. This suggests that ARG levels and microbiological community composition in aquaculture should be conventionally determined to assess potential risks to public health.

“…Notwithstanding, the rich applications of Cannabidiol (CBD) as an antimicrobial, most bacteria have developed strategies of resisting Cannabidiol (CBD) similar to most antimicrobials and this pose's threat to public health [29,30]. Recently we have demonstrated that Cannabidiol (CBD) has potent antimicrobial activity against two strains of Salmonella (Typhimurium and Newington), as compared to some common broad spectrum antibiotics such as polymyxin B, Azitromycin, and Kanamycin [28,31].…”

The emergence of multidrug resistance poses a huge risk to public health globally. Yet these recalcitrant pathogens continue to rise in incidence rate with resistance rates significantly outpacing the speed of antibiotic development. This therefore presents an aura of related health issues such as untreatable nosocomial infections arising from organ transplants, surgeries, as well as community acquired infections that are related to people with compromised immunity e.g., diabetic and HIV patients etc. There is a global effort to fight multidrug resistant pathogens spearheaded by the World Health Organization, thus calling for research into novel antimicrobials agents to fight multiple drug resistance. Previously, our laboratory demonstrated that Cannabidiol (CBD) was an effective antimicrobial against Salmonella Typhimurium (S. Typhimurium). However, we observed resistance development over time. To understand the mechanisms S. Typhimurium uses to develop resistance to Cannabidiol (CBD), we studied the abundance of bacteria lipopolysaccharide (LPS) and membrane sterols of both susceptible and resistant S. Typhimurium. Using real-time quantitative polymerase chain reaction (rt qPCR), we also analyzed the expression of selected genes known for aiding resistance development in S. Typhimurium. We discovered that there was a significantly higher expression of blaTEM, fimA, fimZ, and integrons in the CBD-resistant bacteria, and these were also accompanied by a shift in abundance in cell surface molecules such as lipopolysaccharide (LPS) and sterols.
