Antibiotic misuse Antibiotic misuse Antibiotic misuse, sometimes called antibiotic abuse or antibiotic overuse, refers to the misuse or overuse of antibiotics, with potentially serious effects on health. It is a contributing factor to the development of antibiotic resistance, including the creation of multidrug-resistant bacteria, informally called "super bugs": relatively harmless bacteria (such as staphylococcus, enterococcus and acinetobacter) can develop resistance to multiple antibiotics and cause life-threatening infections. Antibiotics have been around since 1928 when penicillin was discovered by Alexander Fleming. In the 1980s, antibiotics that were determined medically important for treatment of animals could be approved under veterinary oversight. In 1996, the
Broad-spectrum antibiotic that lists the susceptibility of community-acquired and hospital-acquired bacteria is helpful in guiding empiric therapy. Many professional organizations (for example, the Infectious Disease Society of America) publish guidelines for empiric antibiotic therapy, as do hospitals, with their choices tailored for their specific resistance patterns. Many of these guidelines also offer guidance on antibiotic dose and duration of therapy. Once a specific species has been identified and its susceptibilities determined, antibiotics can be "narrowed" to a medication which targets a more specific range of bacteria. If no specific species are identified, patients may continue on the empiric regimen. There are an
