The lack of treatment systems for pollutants in family-livestock and poultry sites results in large amounts of untreated manure and urine being directly discharged to environment. The risks from veterinary antibiotic (VA) and heavy metal (HM) exposure in the rural environment require further research. In this investigation, 221 samples (feed, manure, surface soil, soil profiles, water, and plant) were collected from 41 livestock and poultry farms (swine, chichen, and cattle). Copper (Cu), zinc (Zn), oxytetracycline (OTC), and enrofloxacin (ENR) were frequently detected in the samples. Metals and VAs in sandy loam soils were more inclined to migrate to deep layers than those in loam soils. Copper and Zn in the polluted soils mainly existed in available forms, which facilitated their migration to deep soil layers. In this study, OTC was also observed to migrate more easily to deeper soil layers than ENR due to its relatively high pKa value. Eighteen antibiotic resistance genes (ARGs) and 5 metal resistance genes (MRGs) along with one mobile genetic element (MGE) occurred in the soils at 80 cm depth. Luteimonas, Clostridium_sensu_stricto_1, and Rhodanobacter were dominant genera detected in the soil samples from different sites, which might increase migration of ARGs or degradation of VAs. An ecol. risk assessment suggested that VAs posed threats to the growth of Triticum aestivum L, Cucumis sativus L, and Brassiaca chinensis L. Remediation techniques including biochar/modified biochar, anaerobic digestion, and manure composting should be developed urgently for joint HM and VA pollution. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Quality Control of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid).

Distribution and ecological risks of pharmaceuticals and personal care products with different anthropogenic stresses in a coastal watershed of China was written by Wang, Chenchen;Lu, Yonglong;Wang, Cong;Xiu, Cuo;Cao, Xianghui;Zhang, Meng;Song, Shuai. And the article was included in Chemosphere in 2022.COA of Formula: C16H18FN3O3 The following contents are mentioned in the article:

The occurrences of pharmaceutical and personal care products (PPCPs) in both freshwater and sea have been widely reported. However, pollution control requires further information on riverine discharges with influence of land-based activities and associated risks to estuarine ecosystems. This study investigated the spatial occurrences and the relationship to sociodemog. parameters of 30 PPCPs in 67 rivers along the Bohai coastal region. The results showed that PPCPs were mainly deposited in aquatic phase, and the partitioning coefficient between water and sediment was highly determined by chem. properties. The levels of 30 PPCPs in rivers ranged from 8.33 to 894.48 ng/L, showing a large variance among regions. Caffeine, sulfamethoxazole, sulfamethazine, ofloxacin, anhydro-erythromycin, and trimethoprim were found to be the major pollutants. Multivariable anal. method was used to assess the correlation of PPCPs markers to socio-economic parameters. The results indicated that domestic emissions contributed most to the occurrences of PPCPs in the riverine water. Risk assessment result indicated that sulfamethoxazole, caffeine, tetracycline, and carbamazepine ranked top four with the highest risks to the most sensitive aquatic organisms. The results identified caffeine and carbamazepine with high detection frequency and concentration as the priority chems., while sulfamethoxazole and erythromycin should also be concerned due to their potential threats in specific rivers. This study provides valuable information for pollution control over PPCPs riverine discharges in estuarine regions.

The increasing presence of drugs in the environment has caused great concern in recent years due to their adverse side effects, whether related to animals or humans. In this aspect, the search for methods capable of controlling and monitoring these emerging contaminants in a simple, fast, low-cost, and environmentally friendly way becomes a very important research area that can assist in the preservation of the environment and human health. Therefore, the present work aims to propose for the first time the simultaneous electroanal. quantification of two drugs, extremely consumed worldwide (dipyrone and norfloxacin) of different classes (analgesic and antibiotic), in environmental and biol. samples (organic fertilizer, water, and urine). For this, a com. disposable boron-doped diamond electrochem. sensor (screen-printed electrodes) was used, in conjunction with portable equipment. A simple procedure was fully optimized for the determination of these two analytes by square wave voltammetry (SWV), including the choice of the best working pH and operational parameters of the technique. The SWV operational parameters were optimized using unified multivariate optimization for the best anal. condition for both drugs. The proposed method presents limit of detection of 0.30 and 0.40μmol L^-1 for dipyrone and norfloxacin, resp. The anal. of the samples showed a recovery ranging from 94.0 to 105.0%, demonstrating that the method is suitable for performing the simultaneous determination in a few seconds, with no need for sample pre-treatment steps, and in a sustainable way.

Fabrication of 3D lignosulfonate composited sponges impregnated by BiVO₄/polyaniline/Ag ternary photocatalyst for synergistic adsorption-photodegradation of fluoroquinolones in water was written by Gao, Boqiang;Tao, Koukou;Xi, Zhonghua;El-Sayed, Mayyada M. H.;Shoeib, Tamer;Yang, Hu. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Category: piperazines The following contents are mentioned in the article:

In this work, a 3D lignosulfonate composited poly(vinyl formal) (PVF) sponge impregnated by BiVO₄/polyaniline (PANI)/Ag ternary photocatalyst (PLS-BiVO₄/PANI/Ag) was designed and fabricated. The synergistic adsorption-photodegradation of five fluoroquinolones (FQs) antibiotics onto PLS-BiVO₄/PANI/Ag was investigated. Incorporating lignosulfonate as a carrier on PVF sponge improved its structural properties and enhanced its adsorption performance toward FQs. The BiVO₄/PANI/Ag ternary photocatalyst was well-dispersed and tightly bound to the composited sponge, thus it efficiently degraded the adsorbed FQs through surface photodegradation PLS-BiVO₄/PANI/Ag achieved >90% removal efficiency for all examined FQs within 2.0 h in a batch system, while it maintained a steady 80% removal efficiency for 30.0 h in a continuous dynamic treatment system. Photoelec. characterizations and ESR results showed that BiVO₄/PANI/Ag was consistent with the type II heterostructure and effectively improved the utilization of visible light and the separation of photogenerated electron-hole pairs. The hole was the dominant active species in the degradation of FQs, while the main degradation pathways included defluorination, decarboxylation and destruction of piperazine ring. The prepared composited sponge is thus characterized by its high performance, convenient operation, eco-friendliness, and practicality in real water treatment systems since it undergoes self-purification and is easily recovered from water without mass loss.

The increase in bacterial resistance to available antibiotics has driven several researchers to search for new agents with therapeutic properties. Diosgenin is a naturally occurring steroidal saponin that has demonstrated several pharmacol. properties. In the present study, we report the antimicrobial activity of diosgenin against the standard and multidrug-resistant bacteria of Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, in addition to the efflux pump inhibitory activity against Staphylococcus aureus strains carrying NorA and MepA pumps. For this purpose, the broth microdilution method was used, from which the value of the Min. Inhibitory Concentration (MIC) was obtained, and this was associated with subinhibitory concentration (MIC/8) with antibiotic of clin. use and ethidium bromide for strains carrier by efflux pump. Diosgenin showed antimicrobial activity for standard S. aureus bacteria and potentiating activity in association with gentamicin and ampicillin for P. aeruginosa multidrug-resistant bacteria, it also showed potentiation in association with norfloxacin against the E. coli strain and gentamicin against the S. aureus strain. Antimicrobial activity against efflux pump-bearing strains revealed that saponin did not interfere with the efflux pump mechanism or intervened antagonistically. Thus, saponin has shown to be very promising against bacterial resistance in association with aminoglycoside, fluoroquinolones and beta-lactam, however addnl. studies should be carried out to better elucidate the mechanism of action of diosgenin.

Distribution of florfenicol and norfloxacin in ice during water freezing process: Dual effects by fluorine substituents was written by Sun, Heyang;Chen, Tianyi;Zhang, Liwen;Dong, Deming;Li, Yanchun;Guo, Zhiyong. And the article was included in Environmental Pollution (Oxford, United Kingdom) in 2022.Recommanded Product: 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid The following contents are mentioned in the article:

Distribution in ice is regarded as one of important transport modes for pollutants in seasonal freeze-up waters in cold regions. However, the distribution characteristics and mechanisms of fluorinated antibiotics as emerging contaminants during the water freezing process remain unclear. Here, florfenicol and norfloxacin were selected as model fluorinated antibiotics to investigate their ice-water distribution. Effects of antibiotic mol. structure on the distribution were explored through comparative studies with their non-fluorinated structural analogs. Results showed that phase changes during the ice growth process redistributed the antibiotics, with antibiotic concentrations in water 3.0-6.4 times higher than those in ice. The solute-rich boundary layer with a concentration gradient was presented at the ice-water interface and controlled by constitutional supercooling during the freezing process. The ice-water distribution coefficient (KIW) values of antibiotics increased by 34.8%-38.0% with a doubling of the cooling area. The solute distribution coefficient (Kbs) values of antibiotics at -20°C were 65.6%-70.3% higher than at -10°C. The KIW and Kbs values of all antibiotics were neg. correlated with their water solubilities. The fluorine substituents influenced the binding energies between antibiotics and ice, resulting in a 1.1-fold increase in the binding energy of norfloxacin on the ice surface relative to its structural analog pipemidic acid. The results provide a new insight into the transport behaviors of fluorinated pharmaceuticals in ice-water systems.

Genome mining reveals polysaccharide-degrading potential and new antimicrobial gene clusters of novel intestinal bacterium Paenibacillus jilinensis sp. nov. was written by Ma, Ke;Chen, Wei;Yan, Shi-Qing;Lin, Xiao-Qi;Liu, Zhen-Zhen;Zhang, Jia-Bao;Gao, Yu;Yang, Yong-Jun. And the article was included in BMC Genomics in 2022.Product Details of 70458-96-7 The following contents are mentioned in the article:

Drug-resistant bacteria have posed a great threat to animal breeding and human health. It is obviously urgent to develop new antibiotics that can effectively combat drug-resistant bacteria. The commensal flora inhabited in the intestines become potential candidates owing to the production of a wide range of antimicrobial substances. In addition, host genomes do not encode most of the enzymes needed to degrade dietary structural polysaccharides. The decomposition of these polysaccharides mainly depends on gut commensal-derived CAZymes. We report a novel species isolated from the chicken intestine, designated as Paenibacillus jilinensis sp. nov. and with YPG26T (= CCTCC M2020899T) as the type strain. The complete genome of P. jilinensis YPG26T is made up of a single circular chromosome measuring 3.97 Mb in length and containing 49.34% (mol%) G + C. It carries 33 rRNA genes, 89 tRNA genes, and 3871 protein-coding genes, among which abundant carbohydrate-degrading enzymes (CAZymes) are encoded. Moreover, this strain has the capability to antagonize multiple pathogens in vitro. We identified putative 6 BGCs encoding bacteriocin, NRPs, PKs, terpenes, and protcusin by genome mining. In addition, antibiotic susceptibility testing showed sensitivity to all antibiotics tested. This study highlights the varieties of CAZymes genes and BGCs in the genome of Paenibacillus jilinensis. These findings confirm the beneficial function of the gut microbiota and also provide a promising candidate for the development of new carbohydrate degrading enzymes and antibacterial agents.

Pseudomonas aeruginosa is a multidrug-resistant bacterial strain with the ability to produce exotoxin A which can pose a serious threat to freshwater ecosystems by having pathogenicity against eukaryotes. Detoxification of exotoxin A and disinfection of P. aeruginosa are the main aims of this study. Using a high dosage of antibiotics might have more toxic effects on ecosystems while cold atm. plasma (CAP) can promise reliable, rapid, and environmentally friendly detoxification and disinfection. In this study we produced CAP reinforced by H₂O₂/H₂O cold vapor to detoxify exotoxin A and inactivate P. aeruginosa in freshwater. We used Gammarus roeseli as the indicator of ecotoxicity in freshwater. The mortality of G. roeseli individuals elucidated that 420 s of CAP-based treatment under a surface dielec. barrier discharge (SDBD) set up can effectively passivize exotoxin A in freshwater. Meanwhile, a considerable decline in the concentration of exotoxin A was observed in treated samples due to the disruption of the protein structure. Ignorable side effects and changes to the physiochem. properties were observed On the other hand, 8.2-log reduction of P. aeruginosa viable cells was observed after 300 s of treatment by our CAP-based strategy. This study also showed that the combination of hydrogen peroxide and CAP can significantly increase the decontamination power of hydrogen peroxide and our strategy can eliminate the need of using high concentrations of H₂O₂ which decreases environmental concerns.

Escherichia (E.) coli causes colibacillosis in swine and humans, and is frequently associated with antimicrobial resistance. In this study we aimed to compare antimicrobial resistance, O-serogroups, virulence genes, and multi-locus sequence type of E. coli between isolates from pigs and patients suffering from diarrhea, and the most prevalent pathogenic E. coli strain from swine isolates in Korea. We tested 64 and 50 E. coli strains from pigs and patients suffering from diarrhea for antimicrobial susceptibility test, virulence genes, O-serogroups, and multi-locus sequence typing. We confirmed that isolates from swine showed significantly higher resistance than from those from patients, especially to fluoroquinolone (ciprofloxacin: 37.5 and 10.0%; norfloxacin: 29.7 and 8.0%, resp.). Stx1 (46.0%) was most frequently detected in patients followed by stx2 (38.0%). There was no significant difference in stx2 (swine: 23.4%, patients: 38.0%). In isolates from patients, O157 (12.0%) was the most prevalent O-serogroup, and two isolates (3.1%) from pigs were confirmed to have O157. Addnl., sequence type (ST) 10 (swine: 6 isolates, patients: 2 isolates) and ST 88 (swine: 2 isolates, patients: 1 isolate) were simultaneously detected. We found that both isolates from swine and human had the stx2 gene, which could cause severe disease. Moreover, antimicrobial resistance was significantly higher in pigs than in patients. These results suggest that pig could act as a reservoir in human infection and antimicrobial resistance could be transferred to human from pigs.

Misuse or overuse of antibiotics can have a variety of detrimental microbial effects. However, the body burden of antibiotics in the general population is currently unclear. In this cross-sectional study, we determined four classes of widely-applied antibiotics (3 imidazoles, 2 sulfonamides, 5 quinolones, and 2 chloramphenicols) in urine samples from 1170 adult residents in Shenzhen, China. Antibiotics were detected in 30.8% of all urine samples with concentrations ranging from <LOD to 3517μg/mL, among which metronidazole, ofloxacin and florfenicol were predominant. Notably, antibiotics prohibited for human or veterinary use were detected in 21.0% of samples, indicating that these antibiotics may still be overused in daily life. We found that the presence of antibiotics in urine is associated with being overweight (OR: 1.386, 95% CI: 1.056-1.819, p = 0.019) and obesity (OR: 1.862, 95% CI: 1.103-3.146, p = 0.020) in the adult population. Multilinear regression anal. showed that a percent increase of hydroxy metronidazole was related to 9.86% pos. change of body mass index (p = 0.029). Interestingly, we also found total antibiotic concentration higher in the unmarried group (p = 0.006). Besides, consumption of smoked foods was correlated with urinary antibiotic levels (p = 0.001), indicating smoked meat may be a potential exposure source of veterinary antibiotics. These results highlight the need to reduce human exposure to banned antibiotics. Future research could focus on assessing the health risk and other outcomes of antibiotic overuse.
