Bacteria and other microorganisms that cause infections are remarkably resilient and can develop ways to survive drugs meant to kill or weaken them. This antibiotic resistance, also known as antimicrobial resistance or drug resistance, is due largely to the increasing use of antibiotics.
Archaeocins and other bacteria that have genes that are resistant to a certain type of antibiotic (such as penicillin,oxacillin and others)
An example is a penicillin resistant pneumonia bacteria, caused by the bacteria Streptococcus pneumoniae.
Some of the bacteria are not killed or rendered incapable of reproducing by the specific antibiotic. The processes of mutation and evolution make the antibiotics ineffective against that particular strain.
If a population of bacteria is treated with a particular drug but not wiped out (eg patient stops taking drugs early or a difficult ongoing infection) the individual bacteria that survive longest and reproduce will tend to be those that are more hardy or "resistant" against that particular treatment. Since their life cycle is so fast they can basically "evolve" into a resistant strain under the right circumstances.
Antibiotics are medicines that are used to kill or stop the reproduction in bacteria. Antibiotics are mainly used to stop infections or Infectious Diseases, and since its discovery, has seen very wide use.
When antibiotics were first discovered, it was seen as a miracle drug, and people used them for almost all types of illnesses. This is now seen as problematic becuase of antibiotic resistance.
Antibiotic resistance is when bacteria has a gene in their DNA that makes them immune to antibiotics. This is usually pretty rare, so in a batch of bacteria maybe .01% will be immune to the antibiotic. The problem is however, when all of the non resistant bacteria is dead the resistant bacteria grows and multiply, and than cannot be killed by antibiotics.
When antibiotics were first discovered, it was seen as a miracle drug, and people used them for almost all types of illnesses. This is now seen as problematic becuase of antibiotic resistance. Many strains of resistant bacterium are now greater in number, and the only way to counter them is to invent different types of anti-biotics. This "battle" will probably carry on indefinitely.
it means that u have only one of something and in the other group have have way more than just one
Antibiotic resistance occurs when bacteria or other microbes builds the ability to resist the effects of the antibiotic. This happens when bacteria changes in a way that reduces or eliminates the effectiveness of the drugs designed to cure infections.
Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic.
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
Unfortunately, in recent years, the treatment of endocarditis has become more complicated as a result of antibiotic resistance
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
They have resistance to the antibiotic.
Chloramphenicol is one of the broad spectrum antibiotic used to treat typhoid fever. Resistance occur by way of mutation in ribosomes, By way of decreased permeability of cell wall and production of inactivating enzyme.
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
