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.
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.
Gram negative bacteria are much more resistant to penicillin because?
Gram-negative bacteria are more resistant to penicillin due to the presence of an outer membrane that acts as a barrier, preventing the antibiotic from reaching its target (peptidoglycan layer). Additionally, gram-negative bacteria possess enzymes called beta-lactamases that can break down penicillin and render it ineffective. These mechanisms make it harder for penicillin to kill gram-negative bacteria compared to gram-positive bacteria.
Are penicillin binding proteins found in gram positive and gram negative bacteria?
Yes, penicillin binding proteins (PBPs) are found in both gram positive and gram negative bacteria. PBPs are enzymes involved in cell wall biosynthesis and are the target of beta-lactam antibiotics like penicillin.
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.

What is the drug study for a ampicillin?
mpicillin /am·pi·cil·lin/ (am″pĭ-sil´in) a semisynthetic, acid-resistant, penicillinase-sensitive penicillin used as an antibacterial against many gram-negative and gram-positive bacteria; also used as the sodium salt.semisynthetic aminopenicillin. indication It is prescribed in the treatment of infections caused by a broad spectrum of sensitive gram-negative and gram-positive organisms.contraindication Known hypersensitivity to any penicillin prohibits its use.adverse effects Among the most serious adverse reactions are anaphylaxis, nausea, and diarrhea. Fever, rashes, allergic reactions, and suprainfection also may occur.
Is penicillin gram negative or gram positive?
undrstnd d fact dat if i had te knowledge den y wuld i ask d PC abut it.......
Does penicillin capsules work for human infections?
Penicillin is not a broad spectrum antibiotic like chloramphenicol or the tetracycline. In fact the penicillin is a narrow spectrum antibiotic. It kills the gram positive and gram negative cocci and gram positive bacilli only. Now a days many bacteria has become resistant to penicillin.
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.
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.
Why are Gram-positive bacteria more susceptible to the effects of penicillin than Gram-negative bacteria?
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.
Why do doctors prescribe amoxicillin instead of penicillin for tonsiitis?
amoxicilin is a semi-synthetic form of penicillin. After the penicillin is extracted, some of it is converted to amoxicillin. penicillin is primarily for gram+ bacteria while amoxicillin is effective against both gram positive and gram negative bacteria.Amoxicillin is better absorbed than penicillin as it can withstand the acidity of stomach juice better than penicillin releasing more antybiotics in to blood stream.
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.
