what is peptidoglycan?

its a polymer which is present in the cellwall of bacteria.it is present in larger amounts in gram positive bacteria than in gram negative bacteria. it forms the basic principle for the gram staining procedure for bacteria. it contains amino acids like N-acetylmuramic acid and N-acetylglucosamine.in gram negative orgs it is in small amounts. they have more amounts of a substance called as lipopolysaccharide.

peptide: Any of various natural or synthetic compounds containing two or more amino acids linked by the carboxyl group of one amino acid to the amino group of another.

eukarotic bacteria are unicellular; fungi can be multicellular whereas bacteria can not. Bacteria move themselves by means of a flagella unlike fungi which don't. Bacteria lack a nucleous and mitochondria unlike fungi. Many bacteria have differing cell walls from fungi. I believe the term used is peptidoglcoans, which describes the cell wall.

Here is a short answer for you.  :)\n\nGram negative bacteria have a lipopolysaccharide (LPS) molecule attached to their outer cell membrane.  LPS is an endotoxin that triggers an immune response in the form of fever and eventually shock as the toxin accumulates in the bloodstream.  \n\nGram positive bacteria do not have LPS.\n\nP.S.  There is no such species as Pseudomonas aureus  :)

Dental plaque is an organized colony of bacteria in your mouth. It keeps the acids the bacteria produce stuck to your teeth. The plaque then protects the coating of acids on your teeth so your saliva can't dilute it, buffer it, or wash it away. This will "eat" your tooth over time.

It's milk that contains both both Bifidus and acidophilus bacteria..  (helps you digets certain foods, similar to what makes yogurt good for us)

You are talking about PAMPs: Pathogen-associated molecular patterns. They are small molecules or parts of molecules typically associated with pathogenicity. They are never found in the host organism and can be used as a way for the immune system to identify a foreign agent. The lipopolysaccharides (LPS) mentioned in the previous answer are an example in prokaryotes. So are bacterial flagellins. Some mucin-like glycoproteins in protozoa like trypanasomes are thought to be eukaryotic PAMPs.

they are evolutionary distinct!\narchae dont have a peptidoglycan cell wall.\nmoreover they live in extreme conditions such as high temp springs and very low pH!

well, if an antiseptic effects peptidoglycan (as many antibiotics do), then it will likely work better on gram-positive bacteria than gram-negative. Unless, of course, it is a strain with extensive exposure to the antibiotic, or is naturally competent and has been exposed to bacteria with resistance genes. Or it has been exposed to an R-plasmid...\n\nBasically, there isn't any particular correlation. It depends on the history of the strain, what bacteria it is, and how the antiseptic you use works.

its a member of the kingdom Protista, which includes eukaryotic, mostly unicellular organisms with animal-like (protozoa), plantlike (algae), or funguslike (slime moilds) modes of nutrition. I take microbiology in collage if u need more info email at Njacobs7477@yahoo.com

Alamethicin is a peptide antibiotic, produced by the fungus Trichoderma viride. It contains the non-proteinogenic amino acid 2-aminoisobutyric acid (Aib), which strongly induces helical peptide structures. The peptide sequence is:\n\nAc-Aib-Pro-Aib-Ala-Aib-Ala-Gln-Aib-Val-Aib-Gly-Leu-Aib-Pro-Val-Aib-Aib-Glu-Gln-Phl\n\n(Ac = acetyl, Phl = phenylalaninol)\n\nCAS number: 27061-78-5\n\nIn cell membranes, it forms voltage-dependent ion channels by aggregation of four to six molecules.

H. pylori is a bacteria that affects the stomach.  It is indicated in stomach cancer.  IgG is antibody, if you have IgG antibodies to H. pylori it means you're probably immune to it, but you've been either exposed to it or you've been vaccinated against it.

Penicillin affects the cell wall of prokaryotes.  Human cells are eukaryotes and do not have cell walls.  Actually, penicillin affects the prokaryote's ability to form the peptidoglycans that make up their cell walls.  Eukaryotic cells (human and any other animal cells) don't contain peptidoglycans.

Interferes with the peptidogylcan layer of the cell wall. Causes cell to be prone to lysis. (Bursting)\n\nWhat I usually do is use google to search for relevant sites. Wikipedia is another great resource with easy to understand information. http://wikipedia.com \n\nHere are some more regarding your question\nhttp://helios.bto.ed.ac.uk/bto/microbes/penicill.htm\nhttp://www.cat.cc.md.us/courses/bio141/lecguide/unit1/prostruct/penres.html\nhttp://mic.sgmjournals.org/\nhttp://www.microbes.info/\nhttp://www.bact.wisc.edu/Microtextbook/\nhttp://www.microbiol.org/\nhttp://www.asm.org/
