Penicillin is effective against bacteria that have a cell wall made of peptidoglycan. Bacteria without this type of cell wall, such as Mycoplasma and some strains of Staphylococcus, are not affected by penicillin. This is because penicillin works by disrupting the formation of the cell wall, leading to the bacteria's death.

Why did they invented penicillin?
It wasn't invented on purpose. It was a Scottish guy that invented it and the story goes: he left a window in his lab opened and went on holiday, when he arrived back at the lab he noticed that the bacterium he had growing in his petree dishes had grown all over except in circles around a piece of mold or fungus or something that had blown into the lab through the window. He extracted the stuff that was in the circle that was clear of bacteria and worked out that the substance must either kill or hinder the growth of bacteria.
Do all bacteria have a glycocalyx?
No, not all bacteria have a glycocalyx. The presence of a glycocalyx in bacteria varies between species and strains. Some bacteria have a thick glycocalyx layer, while others may have a very thin or no glycocalyx at all.
Are all bacteria the same and do not have variations within the species?
No, not all bacteria are the same and there are variations within the species.
Do all bacteria have capsules?
No, not all bacteria have capsules. Capsules are a protective layer of polysaccharides or proteins that some bacteria produce around their cell wall. It is a feature found in some bacterial species but is not universal.
What is the difference between a microbe and bacteria?
Bacteria are tiny living things. Some bacteria are good and some are not good. The difference between bacteria and a microbe, is a word used to describe tiny living things, which means that bacteria is a microbe, however, not all microbes are bacteria. A microbe can also be fungi, and protists, as well as bacteria.
Does penicillin cure all infections and bacteria?
Penicillin is NOT effective against gram positive and negative cocci and gram positive bacilli only. it is not effective against rest of the organisms.
Is penicillin a bacteria?
Yes, penicillin prevents the formation of new bacterial cell wall. If a bacteria reproduces, new cell wall cannot be produced and the cell lyses and dies. However penicillin has no effect on a quiescent (non-reproducing) bacteria. Therefore penicillin is also called a bacteriostatic agent (prevents growth of bacteria), which means penicillin does stop bacteria from reproducing.
Why does penicillin not work on all bacteria?
Penicillin comes from an antibiotic made by one microbe that acts only against certain others. Some microbes are just resistant toward the antibiotic and another will have to be used. At times not enough or a dose that is too weak will prevent the antibiotic from working. Some antibiotics will work only on Gram negative or Gram positive bacteria. Some are broad spectrum and will work on both.It just is that penicillin resistant bacteria are not affected by penicillin. These have mutated and evolved to resist penicillin. These are often called "super bugs".
What is the strongest form of penicillin?
Like most antibiotics, penicillin is very powerful against certain bacteria, and not powerful at all with other bacteria. Example: if I was careless enough to catch gonorrhoea, I would take penicillin in a heartbeat. If I had a urinary infection or lung infection, I would take Levaquin or Augmentin, but not penicillin.
Why is penicillin not effective anymore?
Penicillin does still work, just not as well. This is because the few germs that can survive the antibiotic will then pass on that capabaility to their progeny; the basics of genetics in action. This means that later generations of the same bacteria need more to kill them or, even worse, are entirely immune to the effect of penicillin. Some strains of bacteria have evolved to the point that they are not only unaffected by penicillin itself, but all drugs similar to penicillin (beta-lactams). One such strain is MRSA (methicillin-resistant Staphylococcus aureus).
Does penicillin cure athletes feet?
Penicillin has no effect on the fungus that causes athletes foot. Penicillin itself is derived from a fungus. Penicillin is anti-bacterial, it affects bacteria. Penicillin may be used if the athletes foot is serious enough to cause a bacterial infection. Anti-bacterials can cause athletes foot and other fungal infections to worsen by killing the "good" bacteria we all have on our skin and in our bodies. Some of those bacteria feed on fungi.
Why would your body build up an immune to penicillin?
The body does not build up immunity to penicillin. The bacteria that penicillin is designed to kill does. When you have a bacterial infection a doctor may prescribe penicillin to kill the bacteria off. As you take the penicillin more and more bacteria are killed within your system and you start to feel better. As you start to feel better you become less aware of the symptoms of the infection and are inclined to forget to keep taking the remainder if your penicillin (after all I feel fine you say) the problem however is that some of the bacteria are not killed of if the coarse of medicine is not finished. These bacteria are likely to form a resistance to penicillin as a result of their exposure making the illness harder to treat next time. Some illnesses that were once easily treated with penicillin are now very difficult or impossible to treat. Many as the direct result of over use or improper use of penicillin.
Do natural antibacterials work?
All antibacterials work by definition, otherwise they would not be called antibacterials. (antibacterial: what kills bacteria or hinder their reproduction)Natural antibacterials include penicillin, saliva, salt, or even heat.
Why cant penicillin be used to cure every infection?
Penicillin is effective against gram positive and negative coccus types of bacteria and gram positive bacillus types of bacteria only. So it does not cover all the infections. Now a days many bacteria has developed resistance to it.
Can Staphylococcus grow in penicillin G?
It depends. Some bacteria, like Staphylococcus aureus, have become resistant to penicillin G. Not all species of Staphylococcus are resistant. Even some strains of Staphylococcus aureus are still susceptible to penicillin G.
Can penicillin affect bacterial cells after the cell wall is already formed?
Penicillin is an antibiotic that's becoming more and more common these days. Bacteria are becoming increasingly resistant to it. So the affect it causes on the bacteria actually has to do with what resistance the bacteria strain is. Coming back to your answer, all antibiotics are known to attack the cell walls (without which a bacterium cannot survive). So if the cell wall isn't present, the bacteria can do no harm and will eventually die. But if it is, the penicillin will destroy it. so yes
