Question:
Which is the first antibiotic to be discovered ?
Options:
Tetracycline
Azithromycin
Penicillin
Clindamycin
Correct Answer:
Penicillin
Explanation:
Penicillin was the first antibiotic to be discovered, and it was a chance discovery. Alexander Fleming while working on Staphylococci bacteria, once observed a mould growing in one of his unwashed culture plates around which Staphylococci could not grow. He found out that it was due to a chemical produced by the mould and he named it Penicillin after the mould Penicillium notatum.
