Question

why are antibiotics successfully able to control bacterial infections but not viral infections ? Explain.

Note :- ans only if u know the ans.

Answer 1

antibiotics are the substances which work against a particular organism, which has a particular genetic combination.
Virus do not reproduce on their own but force other cells to make a copy of them viruses. Sometimes, the cell forced can make a 'mistake' in copying the virus' genome. This mutation makes each virus of the same type different and hence no antibiotic can possibly function on virus, because antibiotics function on particular types of germs.

Answer 2

Antibiotics block pathways found in bacteria, so these work by interrupting metabolic pathways.So antibiotics work against bacterial infections. In contrast, viruses can reproduce their own metabolic pathways by infecting eukaryotic organisms and hijacking their metabolic pathways which are not affected by antibiotics. Further...Viruses are Structurally different from bacteria. Viruses insert their genetic into a human cell's DNA in order to reproduce. Antibiotics can't kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. Antibiotics work by interfering with the bacterial cell wall and preventing bacterial replication... Viruses are much smaller and harder to kill than bacteria, with a hardier,less penetrable outer working. I have tried my best to answer clearly.

Hope it helps...
