Penicillin is an antibiotic used to treat many different types of bacterial infections. There also are different types of penicillin, such as penicillin V and G, that are administered for conditions such as leptospirosis and Lyme disease, notes Mayo Clinic. From its discovery in 1928 by Alexander Fleming, penicillin's importance in medicine cannot be understated.
Penicillin was the first antibiotic discovered and since then it is the most used antibiotics, states Healio. With its discovery, infections that often led to death were treatable. Its efficacy was most evident during World War II, where there was a reduction in deaths caused by bacterial infections. Penicillin could be used to treat conditions, such as bacterial meningitis and certain types of pneumonia.
At present, penicillin or its different forms are utilized in the treatment of conditions that include gas gangrene, Helicobacter pylori, typhoid fever and chlamydia, notes Mayo Clinic. Different forms of penicillin are amoxicillin and ampicillin, reports Medical News Today.
