This analysis identifies resistance genes and mutations. (cdc.gov)
A catch-all term that includes both resistance genes and resistance mutations that give a microbe the ability to resist the effects of one or more drugs. (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)
However, in other cases, such deleterious side effects of resistance mutations are undetectable, and resistance can even confer benefits in specific, antibiotic-free environmental settings ( Maharjan and Ferenci, 2017 ). (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)

Khomeini Hospital was reviewed to identify patients who had nosocomial bacteraemia between 1 May 1999 and 31 May 2001 and identify the pathogen responsible and its resisitance to antibiotics. (who.int)
General practitioners are uncertain which patients will benefit from antibiotics but prescribe for sicker patients and for patients from socioeconomically deprived backgrounds because of concerns about complications. (bmj.com)
1 - 3 Qualitative studies in the United Kingdom over the past decade found that doctors overestimated patients' expectations for antibiotics, 4 prescribed antibiotics to maintain the doctor-patient relationship, 4 and often felt uncomfortable prescribing antibiotics. (bmj.com)
5 Australian and American doctors also overestimate patients' expectations for antibiotics. (bmj.com)
We also investigated general practitioners' clinical practice in relation to previous findings-for example, prescribing antibiotics to maintain the doctor-patient relationship, overestimation of patients' expectations for antibiotics, and discomfort experienced on prescribing antibiotics. (bmj.com)
Researchers use genetic clues to track the spread of antibiotic resistant bacteria from the environment to patients. (the-scientist.com)
Predisposed patients may acquire antibiotic-resistant staphylococci from other patients, health care personnel, or inanimate objects in health care settings. (merckmanuals.com)

This led to the development of semisynthetic penicillins that were more potent and effective against a wider range of bacteria. (wikipedia.org)
They have made a discovery that could shorten the road to new and more potent antibiotics. (eurekalert.org)

Coagulase-positive S. aureus is among the most ubiquitous and dangerous human pathogens, for both its virulence and its ability to develop antibiotic resistance. (merckmanuals.com)
The main mode of bacterial resistance in case of Gram-negative pathogens is mediated by the expression of enzymes able to hydrolyze this crucial ring: the β-lactamases [ 3 ]. (degruyter.com)

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

Such strategies implicitly presume that resistance leads to reduced bacterial fitness in an antibiotic-free environment, and therefore these resistant populations should be rapidly outcompeted by antibiotic-sensitive variants. (elifesciences.org)
You might have variants of penicillin or erythromycin lying around the house somewhere. (tgdaily.com)

The antibiogram study revealed that Gram-negative bacteria were highly resistant to penicillin while Staphylococcus was resistant to streptomycin, amoxicillin, and lincomycin. (scielo.br)

Since the 1940s, when the first antibiotic, Penicillin, became available to the public, it and other similar "miracle" drugs have been used over and over through the years to fight infectious disease. (silver-colloids.com)
The earliest antibiotics were developed in the 1940s. (mo.gov)

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)
Biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics. (the-scientist.com)

Antibiotics are categorized into classes of drugs. (cdc.gov)
Amoxicillin and penicillin are very similar drugs. (healthline.com)
Amoxicillin and penicillin are both available as generic drugs. (healthline.com)
The table below lists examples of drugs that most often interact with amoxicillin and penicillin. (healthline.com)
By comparison, drugs, such as antibiotics or antivirals, are usually small molecules that inhibit a specific enzyme or protein, without which a pathogen cannot survive or replicate. (theconversation.com)
With drugs, reducing the probability of resistance can similarly be achieved by using several at the same time - a strategy called combination therapy - which is used to treat HIV and tuberculosis. (theconversation.com)
You could think of the antibodies in your body acting like a massively complex combination therapy , with hundreds of slightly different drugs, thereby reducing the chance of resistance evolving. (theconversation.com)

For example, some bacteria have developed biochemical "pumps" that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic. (mo.gov)

And many medical researchers believe that a rapidly increasing resistance to antibiotics is one of the world's most pressing health problems . (silver-colloids.com)

Antimicrobials are grouped according to the microbes they act against (antibiotics, antifungals, and antivirals). (cdc.gov)
