Question

प्रतिजैविक क्या हैं ? किन्हीं दो के स्रोत बतायें।​

Answer 1

Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.

The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic. But most people use the term when they’re talking about medicine that is meant to kill bacteria.
