What is antibiotic resistance and how does it occur?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

it means that u have only one of something and in the other group have have way more than just one
