  • The effectiveness of β-lactam antibiotics is under siege by multiple pathogenic bacteria. (springer.com)
  • These bacteria can produce β-lactamases that hydrolyze the antibiotic, alter their permeability by increasing efflux or decreasing influx (Gram-negative-specific), and structurally alter existing penicillin-binding proteins (PBPs) to lower the rate of acylation or obtain a completely new penicillin-binding protein with extremely low rates of acylation by most β-lactam antibiotics.

  • genes
  • In this study real-time PCR assays, based on the LUX-technique, were developed for quantification of genes mediating resistance to aminoglycosides [aac(6 ')-Ie + aph(2 ' ')], beta-lactams (mecA), and tetracyclines (tetA and tetB), for use in wastewater environments. (diva-portal.org)
  • The developed LUX real-time PCR assays were shown to be fast and reproducible tools for detection and quantification of the four genes encoding antibiotic resistance in wastewater. (diva-portal.org)
  • Additionally, it will show you how to use genomic analysis tools to analyze whole genome sequencing data to detect resistance genes (and or other genes of interest) in a simple and easy way using online tools freely available. (coursera.org)
  • Understand the concept and be able to apply genomic analysis tools used to detect resistance genes and other relevant genes from Whole Genome Sequencing (WGS) data (with demonstration of selected online tools) Disclaimer: Please note that the guidelines and methods referred or links included in these materials are updated when the videos lectures are produced and before the course is released, however these might become outdated with time.

  • this research represents the first ever to survey quantitatively monitor antibiotic level of resistance genes (ARG) in goat and lamb slaughterhouse utilizing a lifestyle independent strategy, since most research focused on person bacterial types and their particular level of resistance types. (cylch.org)
  • the surveillance and control of spread of antibiotic resistance genes (ARG) throughout meals chain provides great relevance since individuals are increasingly alert to problems over antibiotic resistant bacterias in foods, those of animal origin especially. (cylch.org)
  • The regular transfer of level of resistance genes among web host bacteria is now more noticeable with molecular research, that have shown the distribution from the same gene in various bacteria of human or animal origin . (cylch.org)
  • The main goal of the present study was to quantitatively track the frequency and the distribution of ARG in different slaughterhouse surfaces throughout meat chain production (and in the commercial meat products) by quantitative real-time PCR for tetracycline, beta-lactam and sulfonamide resistance genes. (cylch.org)
  • The observed distribution of resistance plasmids and β-lactamase genes in several clones indicates a high degree of horizontal transfer. (cdc.gov)
  • susceptible
  • Antibiosis resistance affects the biology of the insect so pest abundance and subsequent damage is reduced compared to that which would have occurred if the insect was on a susceptible crop variety. (wikipedia.org)
  • species
  • Cefotetan is as active as cefoxitin against B. fragilis, but is much less effective against other members of the B. fragilis group with resistance rates of 30% to 87%, depending on the species. (rrnursingschool.biz)
  • quantification
  • quantification of ARG in food samples by culture-independent methods should also be used to reveal if there is any actual increase in resistance potential. (cylch.org)
  • foodborne
  • There's a growing curiosity about ecological research of antimicrobial 900515-16-4 supplier level 900515-16-4 supplier of resistance in foodborne bacterias. (cylch.org)
  • multiple
  • The 3-D structure of Bacillus cereus (569/H/9) beta-lactamase (EC3.5.2.6), which catalyses the hydrolysis of nearly all beta-lactams, hasbeen solved at 2.5 A resolution by the multiple isomorphous replacementmethod, with density modification and phase combination, from crystals ofthe native protein and of a specially designed mutant (T97C).
