This analysis does not include mutations that may result in antibiotic resistance or resistance determinants added to newer versions of the ResFinder database or other antimicrobial resistance gene databases. (cdc.gov)
However, the cost of resistance can be mitigated by compensatory mutations elsewhere in the genome, and therefore the loss of resistance may proceed too slowly to be of practical importance. (elifesciences.org)
The extent of resistance loss was found to be generally antibiotic-specific, driven by mutations that reduce both resistance level and fitness costs of antibiotic-resistance mutations. (elifesciences.org)
We conclude that phenotypic reversion to the antibiotic-sensitive state can be mediated by the acquisition of additional mutations, while maintaining the original resistance mutations. (elifesciences.org)
It is frequently assumed that such compensatory mutations mitigate the fitness costs of resistance mutations without affecting the level of resistance. (elifesciences.org)
As the range of targets for compensation is much broader, compensatory mutations are more likely than the reversion of resistance mutations. (elifesciences.org)
If compensatory mutations are indeed widespread, pathogens can reach both high level of resistance and high fitness. (elifesciences.org)
Mutations on the rpoB gene (RNA polymerase) alters antibiotic binding site, preventing drug action. (powershow.com)
Davies' team has identified six mutations that are at the root of the resistance and is looking at how the mutations change the way the protein reacts to antibiotics. (sciencedaily.com)
Once researchers understand how the mutations are preventing antibiotics from doing their work, new drugs can be developed, Davies said. (sciencedaily.com)
Davies said it appears that the mutations restrict the protein's flexibility, preventing the structural changes needed to bind the antibiotic. (sciencedaily.com)
If those movements are critical to its job of binding to peptides and building the mesh that keeps the cell wall intact, how can the mutations block the antibiotic but still allow the normal reaction? (sciencedaily.com)
These mutations might have been selected because they provide the pathogen with the ability to evade the host immune response or to tolerate antibiotics. (fems-microbiology.org)

The protein is walking around the membrane layer as normal, but its active site is blocked by antibiotic, so all those potential interactions with the peptide substrate are fruitless," Davies said. (sciencedaily.com)

since then, in the United States, there has been increased identification of penicillin-nonsusceptible S. pneumoniae (PNSP) (defined as minimum inhibitory concentration {MIC} to penicillin greater than or equal to 0.1 ug/mL), especially penicillin-resistant S. pneumoniae (PRSP) (defined as MIC to penicillin greater than or equal to 2.0 ug/mL).

5 The American Academy of Dermatology (AAD) guidelines recommend coadministration of benzoyl peroxide, a topical bactericidal agent not reported to cause resistance, together with both topical and oral antibiotics. (skintherapyletter.com)

Begin empiric antibiotic coverage according to age and presence of overriding physical conditions. (medscape.com)
The most recent analyses of data from the ARMOR (Antibiotic Resistance Monitoring in Ocular micRoorganisms) Surveillance Program can guide clinicians choosing antibiotic therapy for initial empiric therapy and infection prophylaxis. (ophthalmologytimes.com)

Virtually any antibiotic can be used in dermatology given the broad range of conditions treated. (skintherapyletter.com)

If treated with the wrong antibiotics, it can result in the development of rheumatic heart disease. (aljazeera.com)

Our study indicates that restricting antimicrobial usage could be a useful policy, but for certain antibiotics only. (elifesciences.org)
therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts ( Ajuga bracteosa and Curcuma longa ) versus the bacterial pathogens isolated from the human oral cavity. (scielo.br)
