There are several different mechanisms by which antibiotics kill or prevent the proliferation of bacteria.
For instance, penicillins and cephalosporins bind to specific sites in the bacterial cell wall and prevent the bacterium from making new cell wall, so the wall they have breaks down and the cell dies.
Others, like aminoglycosides, prevent the production of proteins in bacteria, so they cannot reproduce or grow.
Some, like fluoroquinolones bind to a protein that prevents the bacterium from being able to duplicate its DNA.
For as many different antibiotics, there are different mechanisms of action. Some kill the bacteria directly, and are called bactericidal and others prevent the bacteria from spreading and are called bacteriostatic. Bacteriostatic antibiotics slow the growth of the bacteria and allow the immune system to kill it off.
Because antibiotics wipe your immune system of both your good & bad bacteria. Once the good bacteria is removed,it just makes it harder for your immune system to fight off the bad bacteria. After taking anti biotics it is highly recommended to take ACCIDOPHILOUS pills to restore your body's natural balance of good bacteria..
Penicillin inhibits bacterial growth by preventing the formation of peptidoglycan that helps to form the bacterial cell walls. This will then cause the bacteria to weaken and the cell to die.

Disease caused by viruses cannot be cured by antibiotics. Antibiotics ONLY work on bacteria.
Because bacteria and viruses are two completely different things. Antibiotics - as their name implies - will kill bacteria, but antibiotics simply have no effect on viruses.
B. Colds are caused by viruses, and antibiotics only kill bacteria
Viruses ALL ignore antibiotics, Bacterial infections vary in their response depending on the sensitivity of the bacteria to the specific antibiotic.
Bacteria are affected by antibiotics, that is the purpose of them.

bacteria is complit cell or contain cellular material hence specific antibody riquar as compair to virus is difrance
bacteria and they don't cure viruses
Bacteria are treated with antibiotics and viruses are treated with antiviral medications.
