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
Antibiotic sensitivity growth. Other methods to test antimicrobial susceptibility include the Stokes method, Etest (also based on antibiotic diffusion), Agar and Broth dilution methods for minimum inhibitory concentration (MIC) determination. The results of the test are reported on the antibiogram. Ideal antibiotic therapy is based on determination of the aetiological agent and its relevant antibiotic sensitivity. Empiric treatment is often started before laboratory microbiological reports are available when treatment should not be delayed due to the seriousness of the disease. The effectiveness of individual antibiotics varies with the location of the infection, the ability of the antibiotic to reach the site of
