How do penicillins kill bacteria and what is the mechanism behind their antibacterial action?
Penicillins kill bacteria by disrupting the cell wall synthesis process. They work by inhibiting the enzyme transpeptidase, which is responsible for cross-linking the peptidoglycan chains in the bacterial cell wall. This weakens the cell wall, leading to cell lysis and ultimately bacterial death.

How does phenol work against bacteria?
At concentrations above 1% phenol has a significant antibacterial affect. Derivatives of phenol, called phenolics, injure the lipid-containing plasma membranes of bacteria and cause the cell to leak its cellular contents.
What is the definition of trigger mechanism?
A device which sets a machine in motion, usually rapidly.
What is the mechanism of action of serotonin 5HT3 antagonists in the treatment of nausea and vomiting?
Serotonin 5HT3 antagonists work by blocking the action of serotonin on specific receptors in the gut and brain, which helps to reduce nausea and vomiting.
What is the substance that can be decomposed by bacteria action?
biodegradable
Is the diameter of the zone of inhibition a true measure of effectiveness of antibiotics?
The diameter of the zone of inhibition can provide a general indication of the effectiveness of antibiotics against a particular strain of bacteria. However, it is not the sole factor to determine effectiveness as other factors like the type of bacteria, concentration of antibiotics, and the mechanism of action also play a role. Additional tests may be needed to accurately assess the effectiveness of antibiotics.
Is cephalosporin related to the penicillins?
cephalosporins are 'related' in the sense they both contain the beta lactam ring, and have the same antibacterial mode of action (inhibiting synthesis of the cell wall). although cephaosporins come from the fungi A.strictum, whereas penicillin comes from the fungi P.notatum.
What is the mechanism of action of sulfonamides?
Sulfonamides inhibit dihydropteroate synthetase so that the bacteria's nucleotide synthesis is inhibited.
What are bactiricidal antibiotics?
bactericidal antiobitics are those whose mechanism of action involves killing the bacteria, i.e. they act on the bacteria directly. In contrast, bacteristatic antibiotics are those whose mode of action is to stop the growth/multiplication of the bacteria.
Could you name the three classes of antibiotics?
There are more than three classes of antibiotics which are:AminoglycosidesAnsamycinsCarbacephemCarbapenemsCephalosporinsGlycopeptidesLincosamidesMacrolidesMonobactamsNitrafuransPenicillinsPenicillin combinationsPolypeptidesQuinolonesSulfonamidesTetracyclinesAnti-MycobacterialThere are three new classes of antibiotics being used over the past few years:Cyclic lipopeptidesGlycylcyclinesOxazolidinones
What is the mode of action of trichlorocarbanilide?
Trichlorocarbanilide is an antimicrobial agent used in personal care products. It works by disrupting the bacterial cell wall and interfering with microbial enzyme activity, ultimately leading to the death of the bacteria.
What is notable about Aminopenicillins?
Aminopenicillins such as ampicillin and amoxicillin have an extended spectrum of action compared with the natural penicillins
What are antibiotes?
bactericidal antiobitics are those whose mechanism of action involves killing the bacteria, i.e. they act on the bacteria directly. In contrast, bacteristatic antibiotics are those whose mode of action is to stop the growth/multiplication of the bacteria.
Does antibacterial soap kill more bacteria than regular soap?
Actually, "regular" soap doesn't kill germs; it simply weakens their bond to your skin by removing skin oil. The mechanical action of lathering, combined with the flushing action of running water, removes gems but it doesn't necessarily kill them. Antibacterial soaps, on the other hand, not only kill the germs on your skin; they may also leave behind residues that continue the antibacterial action for a few hours. They are also sometimes equal because they both remove the same amount of bacteria on your hands

What is the mechanism of action of iodosalicylamide?
Iodosalicylamide works by inhibiting the growth of bacteria through disrupting their ability to form cell walls, ultimately leading to their death.
