What are the different effects of antimicrobial agents on bacteria?
StaxdeMorgan
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 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
Which antimicrobial agents is the most toxic to humans?
ethylene oxide
How can antibacterial agents that target the ribosomes in humans be safe to use?
Antimicrobial agents have 70's rRNA and humans have 80's rRNA therefore it is safe for humans. Although, humans do have 70's rRNA in mitochondria their can be side effects.
What is the most limited group of antimicrobial agents?
Antiviral drugs are the most limited.
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
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.
Which microorganism is least resistant to antimicrobial agents?
endospores
