What are the mechanisms by which antimicrobial agents work?
Q. (disrupting plasma membrane)...what else?
Asked by Lady B - Wed Apr 2 19:44:08 2008 - - 1 Answers - 0 Comments
A. Cell wall synthesis is inhibited by ss-lactams, such as penicillins and cephalosporins, which inhibit peptidoglycan polymerization, and by vancomycin, which combines with cell wall substrates. Polymyxins disrupt the plasma membrane, causing leakage. The plasma membrane sterols of fungi are attacked by polyenes (amphotericin) and imidazoles. Quinolones bind to a bacterial complex of DNA and DNA gyrase, blocking DNA replication. Nitroimidazoles damage DNA. Rifampin blocks RNA synthesis by binding to DNA directed RNA polymerase. Aminoglycosides, tetracycline, chloramphenicol, erythromycin, and clindamycin all interfere with ribosome function. Sulfonamides and trimethoprim block the synthesis of the folate needed for DNA replication

Most of the available antimicrobial agents are effective against which type of organism?
Q. (this is a question from my microbiology class that i do not know)
Asked by kristie - Sun Jul 8 12:40:11 2007 - - 3 Answers - 0 Comments
A. This question is rather vague. If you're talking very generally, antimicrobial agents are effective against prokaryotic organisms, usually -- bacteria, and so on. Some are more effective against gram-negative ones, but these agents are supposed to kill bacteria without harming your eukaryotic cells.

Q. Define the term selectively toxic. Why is it an important feature of antimicrobial agents?
Asked by Jennifer Christman - Mon Nov 23 20:44:14 2009 - - 1 Answers - 0 Comments
A. In a nutshell, if a substance or compound is said to be selectively toxic, then it is not considered to be a toxin to all things that it comes into contact with. It is only toxic to specific things or in some cases it may only be toxic to one specific thing. It is like taking a hand soap that has a chemically engineered ingredient in it that is only toxic to E.coli. That hand soap is not going to kill any other microbes, cells or tissues that it comes into contact with. For all things that are not the bacteria E. coli, it will be inert and non-toxic. However as soon as it comes into contact with E. coli, it will become toxic and kill that bacteria. This is an important feature in antimicrobial agents as we do not always want… [cont.]

A. When a bacterium comes into contact with certain antimicrobial agents (i.e.: those containing hydrogen peroxide), the catalase enzyme causes a reaction that breaks the hydrogen peroxide into water and oxygen molecules. The catalase test is used for identification of many bacteria -- a drop of 3% H2O2 will bubble, indicating the bacteria is positive for the production of the catalase enzyme.

Are Gram positive or negative more sensitive?
Q. Are Gram positive or Gram negative more sensitive to antimicrobial agents? I was just wondering. It seems that Gram Positive are more sensitive to antibiotics, but they are more resistant to detergents. Can you tell me where you got your source?
Asked by Recorder - Mon Oct 13 22:46:23 2008 - - 1 Answers - 0 Comments
A. The gram stain characteristics have nothing to do with the ability of the germ to kill humans, cause disease, nor their ability to be killed by appropriate antibiotic therapy. The gram stain can give you a clue as to WHICH antibiotics are likely to be more effective. But if given correct treatment, an E. coli (gram negative) infection can be cured just as easily (with gentamicin) as a staph (gram positive) infection treated with vancomycin. And either one could kill you just as easily as well. Can't give you a source - this is just common knowledge. You cannot find any medical source to state otherwise.

name antibiotics that harm pathogens but are safe for humans?
Q. given that both human cells and pathogens synthesize protiens at ribosomal sites, how can antimicrobial agents that target this process be safe for humans? name some of the antibiotics that work in this way.
Asked by roop95630 - Tue Feb 21 17:36:07 2006 - - 1 Answers - 0 Comments
A. Depends on the pathogen. If you are dealing with bacterial pathogens, than its important to remember that bacterial ribosomes are different than human. Human ribosomes are 70s, a weight classification, while bacterial are 80s. So several antibiotics will specifically target bacterial ribosomes. Usually by sitting in the A site, blocking binding of tRNA. Some antibiotics will prevent the transition between the A and P sites. You could also say that competative binding of foreign tRNA could work at the "ribosomal" level. As far as names? Well each one has many different names and slightly different chemical structures.

Asked by cloud851 - Thu Oct 30 16:36:03 2008 - - 1 Answers - 0 Comments
A. Bacteria become resistant to antibiotics because they can mutate. Their genetic information is stored in a circular DNA called a plasmid. Bacteria can swap or modify their plasmids during conjugation (bacterial sexual reproduction). When this happens, they have different DNA, which means they can produce different proteins to resist the antibiotics.
