Penicillin

Penicillin refers to an antibiotic that was accidentally discovered by bacteriologist Fleming in 1928. It inhibits bacterial cell wall synthesis and thereby suppressing the bacterial growth and proliferation, while also having bactericidal effects. It is mainly used against aerobic and anaerobic Streptococcus Rosenbach, enterococcus, Neisseria gonorrhoeae and meningococcus including Streptococcus pneumoniae.
