WebJul 10, 2024 · Some bacteria acquire resistance when they are “given” a gene by another bacterium through a process called horizontal gene transfer (HGT). There are three ways that HGT can occur. Transduction – This occurs when a virus attacks a bacterium and steals some of its DNA. This virus can then attack another bacterium, and drop off the genes it … WebSep 13, 2024 · It happens when bacteria change and resist the effects of an antibiotic. Resistant bacteria may continue to grow and multiply. Each time you take antibiotics there is a risk that the bacteria will become resistant. Resistant infections can be difficult and sometimes impossible to treat. They can spread to other people.
Evidence for evolution - antibiotic resistance in bacteria
WebFeb 2, 2024 · Antibiotic resistance occurs when bacteria can no longer be controlled or killed by certain antibiotics. In some cases, this can mean there are no effective treatments for certain conditions.... WebJan 30, 2001 · There are a number of ways to get a resistance gene: During transformation - in this process, akin to bacterial sex, microbes can join together and transfer DNA to each other. On a small, circular, extrachromosomal piece of DNA, called a plasmid - one plasmid can encode resistance to many different antibiotics. highfive scene

WebAug 23, 2024 · Resistance to antibiotics is often acquired by the transfer of resistance-conferring genes between bacteria, and this acquisition is usually facilitated by a conjugative plasmid. These plasmids encode the genes necessary for two bacteria to pass the plasmid between them, and they can also encode resistance genes. WebAntibiotic resistance Antibiotics are no longer routinely used to treat infections. This is because: many infections are caused by viruses, so antibiotics are not effective antibiotics are often unlikely to speed up the healing process and can cause side effects WebThat's called antibiotic resistance. Some bacteria can naturally resist certain kinds of antibiotics. Others can become resistant if their genes change or they get drug-resistant … how human body systems work
