Penicillin is the anti bacterial antibiotics, which is first time discovered by Alexander Fleming in 1928 from penicillium notatum (Fungus).

Penicillin (PCN or pen) is a group of antibiotics which include penicillin G (intravenous use) , penicillin V (use by mouth) , procaine penicillin, and benzathine penicillin (intramuscular use). Penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today, though many types of bacteria have developed resistance following extensive use. About 10% of people report that they are allergic to penicillin. Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming. People began using it to treat infections in 1942. There are several enhanced penicillin families which are effective against additional bacteria; these include the antistaphylococcal penicillins, aminopenicillins and the antipseudomonal penicillins. They are derived from Penicillium fungi.
