Dear student,

Any substance that inhibits the growth and replication of a bacterium or kills it outright can be called an ANTIBIOTIC. Antibiotics are a type of antimicrobial designed to target bacterial infections within (or on) the body.

In simpler words, Antibiotics are the medicines that inhibits the growth or kills the bacteria causing microbes by blocking the pathway for bacterial synthesis but doesn't affect its own pathway.

In Biology it's ANTIVIRAL not ANTIVIRUS.

An ANTIVIRAL is an agent that kills a virus or that suppresses its ability to replicate and, hence, inhibits its capability to multiply and reproduce.

I hope it helps.

Dear Aspirants ,

Antiviral are drugs that can treat people who have already been infected by a virus. They also can be used to prevent or limit infection when given before or shortly after exposure, before illness occurs. A key difference is that the antiviral drug is effective only when administered within a certain time frame before or after exposure and is effective during the time that the drug is being administered.

Antibiotics are medicines that interfere with the reproduction of bacteria and are, therefore, only useful for treating bacterial infections. Viral diseases, like influenza, can therefore not be treated with antibiotics. What is worse, inappropriate use of antibiotics contributes to the development of antibiotic resistance, a growing health concern. Secondary bacterial infections that may occur in tissues that have been damaged by influenza virus infection may well be treated with antibiotics.

Hope it will helpful

Thanks
