What does antibiotic resistance mean for bacterial infections?

Antibiotic resistance means that the bacteria causing disease are no longer damaged by antibiotics. This can lead to infections that are difficult to treat and may become more serious.

Antibiotic resistance refers to bacterial strains that have changed and are no longer controlled using traditional antibiotic drug therapies. Resistance to antibiotic drugs occurs when the drugs are misused by doctors and people. Doctors often prescribe antibiotics for an infection that is not caused by bacteria. People misuse antibiotics by not completing the course of the drug treatment. Both examples allow bacteria to obtain genes from other bacteria that render them safe from the effects of common antibiotics. Staphylococcus aureus is an example of antibiotic resistant bacteria. This strain became resistant to the most common antibiotics used to treat the bacterium - penicillin and methicillin. This strain developed into methicillin-resistant Staphylococcus aureus, also called MSRA.
