Is penicillin more effective against Gram negative or Gram positive?
Penicillin is more effective against Gram positive bacteria. This is because the peptidoglycan layer of Gram negative bacteria acts as a barrier that makes them less susceptible to penicillin.
Which is more sensitive to penicillin gram posite or gram negative?
Gram-positive bacteria are generally more sensitive to penicillin compared to gram-negative bacteria. This is because gram-positive bacteria have a thinner cell wall that is easier for penicillin to penetrate and disrupt, leading to cell death. Gram-negative bacteria have an outer membrane that provides some protection against penicillin, making them less susceptible.
Which are more sensitive to penicllin?
Gram-positive bacteria are generally more sensitive to penicillin than Gram-negative bacteria. This is because the cell wall of Gram-positive bacteria is more susceptible to the action of penicillin, while Gram-negative bacteria have an outer membrane that provides some protection against the antibiotic.
Are archaea bacteria resistant to penicillin?
Without fully explaining how the penicillin antibitic works: yes, archaea are resistant to penicillin. This is because they don't have peptidoglycan in their cell wall. Penicillin works by lowering the newly formed peptidoglycan in multiplying bacteria. It also does other things. The reason it works (this is natural penicillin G) only on Gr+ is because the can't get through the GR- cell wall. (I say this because both + and - HAVE peptidoglycan in their cell wall)
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".
Why some bacteria are resistant from penicillin?
Because its bigger and bigger is better ;)
Why is penicillin not as effective as it was fifty years ago?
This isn't entirely true. Penicillin is still as effective against the bacteria that it combated 50 years ago, but new strains of penicillin resistant bacteria have evolved since 50 years ago. This means that penicillin is less effective against a larger percentage of bacteria than it was 50 years ago, solely because of the new, anti-biotic resistant strains.

Can i take amox tr-k clv if im allergic to penicillian?
Yes, amoxicillin is a member of the penicillin group of antibiotics. Yes and No, it is more of the bacteria of penicillin than the actual antibiotic. It is a part of the penicillin family true, and is given to patients that are allergic to penicillin. Not just because the bacteria is penicillin resistant.
Why might a gram-negative infection be harder to treat than gram-positive infection?
In short, it's because they have a membrane around their cell wall that both increases their toxicity, and makes them more resistant to antibiotics. It makes them more resistant because many antibiotics, such as penicillin, work by destroying the cell walls of bacteria. Because they have an extra membrane around their cell walls, gram negative bacteria have extra protection against the antibiotics.
Why doesn't penicillin work on all bacteria?
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.
Does penicillin kill gram negative or gram positive or both?
Penicillin primarily targets and is more effective against gram-positive bacteria by disrupting their cell wall synthesis. It is less effective against gram-negative bacteria due to the presence of an outer membrane that restricts penicillin's access to the cell wall.
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).
