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?
Different bacteria have unique structures, metabolic pathways, and resistance mechanisms. An antimicrobial agent may target a specific bacterial structure or pathway, making it effective against a certain type of bacteria but not others. In addition, bacteria evolve and acquire resistance to antimicrobial agents through various mechanisms, further reducing their effectiveness against certain 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?
The paper disc diffusion method is a laboratory technique used to test the effectiveness of antimicrobial agents against bacteria. In this method, paper discs containing different antimicrobial agents are placed on a solid agar plate inoculated with bacteria. The zone of inhibition around each disc indicates the susceptibility of the bacteria to the specific antimicrobial agent.
Why do you need antimicrobial agents?
Antimicrobial agents are used to fight bacteria, viruses, fungi, and parasites that can cause infections and diseases. They help to prevent the spread of harmful microorganisms, control infections, and treat various medical conditions. Additionally, antimicrobial agents are important in healthcare settings to reduce the risk of healthcare-associated infections.

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

The zone of inhibition around each disc indicates the susceptibility of the bacteria to the specific antimicrobial agent.
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?
Some examples of antimicrobial agents are antibiotics (such as penicillin and erythromycin), antiviral drugs (such as acyclovir and oseltamivir), and antifungal medications (such as fluconazole and terbinafine). These agents are used to treat bacterial, viral, and fungal infections, respectively.
