Antibiotic resistance genes in Escherichia coli – literature review

Critical Reviews in Microbiology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 35

Published: April 18, 2025

Antimicrobial resistance threatens humans and animals worldwide is recognized as one of the leading global public health issues. Escherichia coli (E. coli) has an unquestionable role in carrying transmitting antibiotic genes (ARGs), which many cases are encoded on plasmids or phage, thus creating potential for horizontal gene transfer. In this literature review, authors summarize major occurring E. bacteria, through classes. The aim was not only listing against clinically relevant antibiotics, used treatment infections, but also to cover entire carriage coli, providing a more complete picture. We started with long-standing groups (beta-lactams, aminoglycosides, tetracyclines, sulfonamides diaminopyrimidines), then moved toward newer (phenicols, peptides, fluoroquinolones, nitrofurans nitroimidazoles), every group we summarized grouped by mechanism their action (enzymatic inactivation, efflux, reduced permeability, etc.). observed that frequency mechanisms changes different groups.

An Antimicrobial Polymer Brush Coating to Fabricate High-Performance, Durable, Self-Sterilization, and Recyclable Face Masks

Chemistry of Materials, Journal Year: 2023, Volume and Issue: 35(21), P. 9245 - 9256

Published: Oct. 30, 2023

The ubiquity of airborne germs poses a significant threat to human respiratory health, as demonstrated by the COVID-19 pandemic, and since outbreak COVID-19, masks have become necessity. However, commercially available only act physical barrier do not effectively kill germs. Therefore, wearer these becomes susceptible secondary infections cross-infections. Moreover, widespread use disposable with short life spans has placed heavy economic environmental burden on society. Herein, inspired natural tomato trichomes, an on-demand, simple biomimetic strategy was developed impart durability, prolonged service life, antimicrobial antiviral properties commonly used using polymer brush (PPDV) coating. PPDV coating designed firmly adhere interfacial fibers (termed HPDV-masks), which aided in achieving outstanding bacterial inhibition rates (99.25%), preventing adhesion (88.36%), killing virus within contact time 3 min. could be readily wide variety improve filtration performance aerosols solid particles. Importantly, HPDV were also highly durable exhibited long retaining their efficiency for bacteria after 10 cycles exposure showing no deterioration over 1 month. sustainable fabrication multifunctional enhancements herein shows great potential application prospects improving performances personal protective equipment spread

Indoor microbes are readily transmitted among humans in indoor environments. Therefore, this study employed 16S rRNA gene and ITS amplicon profiling to investigate the dust-associated bacterial fungal communities six facilities Busan, South Korea. The collected samples were categorized into two groups: multiple-use (MUFs), including a public bathing facility, business office, food court; transportation (PTFs), subway stations an airport. diversity MUF was significantly higher than (p < 0.05). However, no significant differences between observed PTF > Moreover, abundances of certain microbial taxa varied, suggesting that community structure primarily determined by source environment. Gram-positive genera, such as Corynebacterium, Kocuria, Staphylococcus—all which originated natural environment—were relatively predominant samples; Aspergillus, Penicillium, Malassezia human commensal taxa, more samples. These results suggest different can be formed depending on purpose facility type, level passenger traffic, surrounding findings may help researchers understand multi-use facilities.
