  • Because most Enterobacter species are either very resistant to many agents or can develop resistance during antimicrobial therapy, the choice of appropriate antimicrobial agents is complicated. (medscape.com)
  • Resistance against antimicrobial agents (AMR) is a global public health threat, greatly contributing to the global burden of disease. (biomedcentral.com)
  • Antimicrobial resistance constitutes a threat to global health, especially in lower-middle income countries (LMICs) including Indonesia. (eur.nl)
  • It is a natural phenomenon, but improper use of antibiotics is contributing to it by selecting resistance and complicating bacterial infection-control strategies. (pasteur.fr)
  • In order to gauge progress, WHO, FAO and OIE have jointly administered a tripartite annual antimicrobial resistance country self-assessment survey since 2016, with questions structured around the strategic objectives of the global action plan. (who.int)
  • Whole-genome sequencing (WGS) was used to identify possible resistance determinants in this mutant. (microbiologyresearch.org)
  • This data set describes antimicrobial resistance (AMR) data from the WHO European Region gathered through the Central Asian and Eastern European Surveillance of Antimicrobial Resistance (CAESAR) network and the European Centre for Disease Prevention and Control (ECDC) European Antimicrobial Resistance Surveillance Network (EARS-Net). (who.int)
  • Data from the European Antimicrobial Resistance Surveillance Network (EARS-Net). (who.int)
  • Unfortunately, we look for no more than 4 markers, but when we do genome sequencing we get to know a lot many more (components) that may be driving resistance. (thehindu.com)
  • Presence of Efflux Pump may not be associated with resistance. (cdc.gov)
