The excessive use of gatifloxacin (GAT) can seriously pollute the environment and damage human health. Therefore, reliable detection its concentration is essential for environmental protection physical Herein, an efficient stable voltammetric sensor based on zirconium-based metal–organic framework/carboxylated multiwalled nanotube nanocomposites (UiO-66/MWCNT-COOH) was constructed determination GAT. morphologies, microstructures, electrochemical properties UiO-66/MWCNT-COOH were investigated by using various microscopic, spectroscopic, techniques. showed good electrocatalytic activity GAT oxidation with remarkable response signals, which primarily attributed to synergistic effect from UiO-66 MWCNT-COOH. Electrochemical kinetics studies revealed that irreversible diffusion-limited reaction involving two protons electrons. anodic peak current linearly correlated in range 0.05 10 μM a low limit 0.0075 μM. Moreover, demonstrated high selectivity, reproducibility, repeatability as well extraordinary long-term stability (at least 7 weeks). proposed reliably detected trace effluent, milk, serum, eye drops satisfactory recoveries. Together outstanding merits such cost, robust response, short assay time, sensitivity, shows enormous prospects situ multiple antibiotics.

Antibiotic resistant bacteria in food systems: Current status, resistance mechanisms, and mitigation strategies

Agriculture Communications, Journal Year: 2024, Volume and Issue: 2(1), P. 100027 - 100027

Published: Feb. 3, 2024

The pervasive use of antibiotics in agriculture and animal husbandry has raised a significant concern—residual antibiotic contamination food, which contributes to the natural evolution resistance pathogenic microbial strains. emergence communities poses global threat food safety security. Recently, situation been exacerbated by discovery novel strains resistant bacteria (ARB) plant- animal-derived foods. These microbes can enter human body through direct contact with affected animals or consumption contaminated In this review, we explore prevalence contaminants at various locations around world, delve into molecular mechanisms behind acquisition antimicrobial resistance, examine current strategies employed mitigate spread pathogens, discuss emerging technologies aimed halting trend that projects 10 million annual deaths 2050 as result ARB agriculture. Genetic processes, including mutations, efflux pump activity, horizontal gene transfer, play crucial roles widespread distribution community. Effectively addressing requires development methodologies rapidly detect supply chain. Therefore, several established rapid diagnostic techniques such Quick, Easy, Cheap, Effective, Rugged, Safe (QuEChERS) methodology, aptasensors, fluorescence-based Metal Organic Frameworks. Additionally, innovative fight nano-antibiotics, antibiotics, synthetic biology, bacteriophages, predator bacteria. Here, propose omics biochar potential tools for combating ARB. We anticipate review article will serve valuable resource future research, particularly designed not only suppress activities genes but also potentially reverse are already communities.
