Antimicrobial agents can have one of the following three effects:
- Bacteriostasic: usually inhibit protein synthesis and act by binding to ribosome
- Bactericidal: bind tightly to their cellular targets and are not removed by dilution. Lysis and loss of cellular contents does not occur
- Bacteriolytic: induce killing by cell lysis, include agents that destroy cell wall.

Why isnt one antimicrobial agent equally effective against all three bacteria?
All three bacteria have different species, cell wall strengths and weaknesses so different antimicrobial agents will be needed to affect each. It's common that the antimicrobial agent does not kill the bacteria, only stopping the growth of the bacteria.
What is the easiest to treat with antimicrobial agents?
Bacterial infections are generally the easiest to treat with antimicrobial agents because there are a wide variety of antibiotics available that specifically target bacteria. Most bacterial infections respond well to antimicrobial treatment when the appropriate antibiotic is chosen based on the specific bacteria causing the infection.
What are microbial agents?
Antimicrobial agents are compounds that inhibit or kill microbes or microorganims, e.g bacteria and fungi. Antimicrobial agents can be chemicals or biological in compostion. Chemical based antimicrobial agents are antibiotics where are biological based are antimicrobial peptides. Antimicrobial agents inhibit or kill microbes by breaking there cell wall or inhibiting some metabolism or bind to DNA and prevent the replication, thus stopping the multiplication of the microbes in the body
What is the antimicrobial agents existed in the bactine?
Bactine contains two key antimicrobial agents: benzalkonium chloride and lidocaine. Benzalkonium chloride acts as a disinfectant to kill bacteria and viruses, while lidocaine provides pain relief by numbing the skin.
Paper disc diffusion method?
Paper disc diffusion method is used to see what antibiotics or compounds inhibit bacterial growth, or are bacteriostatic. The paper discs are soaked with a select antibiotic or chemical and then placed on a lawn of bacteria in a petri dish. The zones of inhibition are measured around where the disc was placed to determine whether the bacteria was resistant or susceptible to the particular antibiotic or chemical chosen.
Why do you need antimicrobial agents?
Some people are against antimicrobial agents because there is a school of thought that considers microbes and bacteria to be necessary to our health and hygiene. This is because introducing bacteria into our systems can help keep our immune system stimulated.

What are the 4 basic methods in which antimicrobial agents work?
Antimicrobial agents work on bacteria by stopping growth of the, cell wall, cell membrane, protein and changing the protein function. Taking antimicrobial medicine, sterilization-using heat, radiation, disinfectants or antiseptics can do this.
Is chlorhexidine bactericide or bacteriostatic agent?
Bactericidal antimicrobial agents kill the microbe, whereas bactericidal agents inhibit the growth of the microbe. Chloehexidine is an agent that kills bacteria, thus, it is considered a bactericidal antimicrobial agent.

What has the author Jonathan I Ravdin written?
Jonathan I. Ravdin has written: 'Antimicrobial agents and phagocyte-bacterial interactions' -- subject(s): Antibacterial agents, Bacteria, Phagocytes, Phagocytosis, Physiology
Which of these antimicrobial agents has the fewest side effects - a. Penicillin b. Streptomycin c. Chloramphenicol d. Tetracycline e. Erythromycin?
a.) penicillin

Which antimicrobial agents is the most toxic to humans?
One of the most toxic antimicrobial agents to humans is colistin. It is known for its potential to cause renal toxicity and neurotoxicity, particularly when administered in high doses. It is reserved for use in serious infections due to its potential side effects.
What are some examples of antimicrobial agents?
Antibacterial are agents used to disinfect surfaces thereby eliminating potentially harmful bacteria. Common agents are alcohols, chlorine, peroxides, and aldehydes. Also, triclosan, triclocarban, and benzalkonium chloride are the longer acting agents we now use for surfaces.
