Penicillins have a bacteriocidal effect on Gram-positive bacteria. In Gram-positive cells, peptidoglycan makes up as much as 90% of the thick, compact cell wall, and is the outermost layer.

Penicillins are not effective against Gram-negative bacteria, which have cell walls in which peptidoglycan is not the outermost layer, but that lies between the plasma membrane and a lipopolysaccharide (LPS) outer membrane. Penicillin cannot access the peptidoglycan of Gram-negative cells.

Can penicillin kill the bacteria in the underarm?

depends on the penicillin type and the bacterial cause, but if it is a susceptible organism and the type of penicillin is correct then the answer is yes. If you have been prescribed the penicillin by your doctor, then the answer is yes.


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.


Why doesn't penicillin kill fungal disease?

Penicillin kills susceptible bacteria by interfering with the bacterial cell wall. Since fungi don't have a cell wall, penicillin can't eliminate fungal infection.


Is b subtilus grampositive?

B. Subtilus is a rod or bacilus shaped, gram positive bacteria


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.


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.


Does penicillin have bacteria?

it is grown from bacteria


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.


What functions do amoxicillin have?

Amoxicillin is for penicillin class of antibiotics. By inhibiting the synthesis of bacterial cell walls, it makes the bacteria expanding and cracking to take sterilization effects. It has good antibacterial activity for the hemolytic streptococcus, pneumonia streptococcus, penicillin enzyme aureus, dung enterococcus, singular proteus and other aerobic gramnegative bacteria and so on. Amoxicillin sodium for injection is suitable for a variety of infections caused by sensitive bacteria for the heavy patients requiring hospitalization or not being able to take by mouth.

If gram positive bacteria are incubated with penicillin in an isotonic solution will it able to grow or lysed explain why?

The gram positive bacteria will be lysed when incubated with penicillin in an isotonic solution. Penicillin inhibits peptidoglycan synthesis, weakening the bacterial cell wall. The isotonic solution prevents osmotic lysis by maintaining equal concentrations of solutes inside and outside the bacterial cell, making the weakened cell wall more susceptible to lysis.


What growth phase will gram - positive bacteria be most susceptible to penicillin?

Bacteria are most sensitive to antibiotics during the exponential stage (rapid growth).
