How does penicillin kill bacteria without harming human cells?
Human cells do not make or need peptidoglycan.
The result is a very fragile cell wall that bursts, killing the bacterium.
No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.
Bacteria can also be selectively eradicated by targeting their metabolic pathways..
How does penicillin treat infection?
It works by killing bacteria. Antibiotics such as penicillin V potassium will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
Does penicillin kill viruses?

Is Penicillin a strong antibiotic?
Because penicillin became one of the most commonly used antibiotics in the world, many bacterial species have gained resistance against it. However, it is still useful for certain bacterial infections. Penicillin is a narrow-range antibiotic that covers gram-positive bacteria and some gram-negative bacteria.

Can penicillin kill all types of bacteria?
When a bacterium divides, penicillin prevents it from reforming a new cell wall, and the two daughter cells “pop”. However, penicillin does not combat all types of bacterial infections; it is most effective against gram-positive bacteria.
Is penicillin made from bacteria?
For many years, scientists knew that certain molds killed some bacteria. … Penicillium mold naturally produces the antibiotic penicillin. 2. Scientists learned to grow Penicillium mold in deep fermentation tanks by adding a kind of sugar and other ingredients.
What bacteria does penicillin treat?
While the number of penicillin-resistant bacteria is increasing, penicillin can still be used to treat a wide range of infections caused by certain susceptible bacteria, including those in the Streptococcus, Staphylococcus, Clostridium, Neisseria, and Listeria genera.
Why is penicillin no longer used?
Beyond allergies, penicillin is becoming less effective over time, as bacteria have become resistant to the antibiotics designed to kill them.
Why do antibiotics not kill viruses?
Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.
