How antibiotic resistance arises


What is antibiotic resistance? Bacteria naturally evolve to develop ways
of not being killed by antibiotics When this happens, these bacteria are known as antibiotic-resistant bacteria Antibiotic resistance can be caused by genetic mutations in the bacterial DNA that lead to a change in cell wall structure,
metabolism, DNA replication or protein production. The antibiotic can then no longer affect its
target structure or process When bacteria are exposed to antibiotics,
the resistant strains have a selective advantage and they survive and multiply, mainly in the gut The gut is an ideal breeding ground for antibiotic resistance, as oral antibiotics have to go via this route The antibiotics come into contact with all different gut bacteria The overuse and misuse of antibiotics speeds up this process and contributes to the high levels of antibiotic resistance seen today
