IMMUNOLOGY

Detailed explanation-1: -Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.

Detailed explanation-2: -Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria. Antibiotics are produced by microorganisms to kill or control the growth of other microorganisms by blocking specific metabolic pathways within the cell.

Detailed explanation-3: -Antibiotics cannot kill viruses or help you feel better when you have a virus.

Detailed explanation-4: -The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis. Drugs used for treatment for viral fever are Acetaminophen(Tylenolothers)ibuprofen (Advil, motrin IB others).

Detailed explanation-5: -If the virus comes back, the bacterium makes RNA from the region of CRISPR specific for that virus. These RNA copies pair up with some cas (CRISPR-associated) proteins. The RNA guides the cas protein to the invading viral DNA, so the protein can destroy it. No more viral DNA, no new viruses.

Detailed explanation-6: -Because antibiotics only fight bacteria, and not viruses, they’re usually ineffective against colds. Sometimes a cold may lead to a bacterial infection, though. In that case, antibiotics would have a benefit if they were able to prevent that kind of infection.
