A 2016 studyreported that between 30% and 50% of all antibiotic prescriptions for common conditions such as ear infections, sore throats and other upper respiratory-type infections may have been inappropriate and unnecessary. Fleming's lab didn't have the resources to fully develop his discovery into a usable drug. Today, there are many natural and synthetic types of penicillin, which are used to treat a wide range of ailments. Alexander Fleming accidentally discovered penicillin in the 1920s by examining his petri dishes containing staphylococcus. Side effects can include diarrhea, an upset stomach, and nausea. Unfortunately, Florey's team ran out of the drug before Alexander was completely healed, and he died. Antibiotic resistance is a growing public health concern worldwide. You will receive a verification email shortly. However, some strains of bacteria have become resistant to penicillin and other antibiotics, making those infections more difficult, and sometimes impossible, to treat.
