Antibiotics are the most common treatment for bacterial infections, according to MedlinePlus. The exact type of antibiotic prescribed depends on the type of bacterial infection, the severity, and where it is located in or on the body.
There are infections, however, that are resistant to treatment by all available antibiotics, as Mayo Clinic explains. The overuse and misuse of antibiotics over the years have contributed to the creation of drug-resistant bacteria; therefore, it is important to only take antibiotics prescribed by a doctor and to follow instructions carefully. Failure to take a full course of antibiotics may contribute to antibiotic resistance.
