  • The multilocus sequence type, multiantigen sequence type, presence of determinants of antimicrobial resistance and relatedness among the isolates were all derived from the sequence data. (who.int)
  • They have the same modes of action as the current drugs and a lot of resistance mechanisms are to the mode of action," Smitten explained. (ourhealthneeds.com)
  • Penicillin inhibits the transpeptidases by permanently binding to their active sites, meaning the substrates can no longer bind (Lobanovska & Pilla, 2017). (operationmedschool.com)

  • Antimicrobial resistance (AMR) monitoring of BRD pathogens is critical to promote appropriate antimicrobial stewardship in veterinary medicine for optimal treatment and control. (edu.au)
  • Thereafter, antibiotic discovery and development of new molecules gradually declined with the parallel emergence of drug resistance of many human bacterial pathogens. (le.ac.uk)
  • Today, the frequency and spectrum of antibiotic resistance in specific bacterial pathogens continues to increase worryingly, with particular concerns on Mycobacterium tuberculosis and on several Gram-positive (e.g. (le.ac.uk)
