what is ment by gram positive?
966917
Gram staining is a laboratory test used for identifying various kinds of bacteria.  Some kinds of bacteria react to the stain and those are gram positive, the rest don't and they are gram negative.  Different kinds of antibiotics are designed to kill bacteria that are gram positive, gram negative or both.

pneumonia with pulmonary abcess.\npseudomonas, staph, or klebsiella are most likely organisms

chemical reactions for staphylococcus aureus  :   MIO (motility indole ornithine) - negative   ,    coagulase slide (+ )and coagulase test tube (+)\ncatalase (+)   .  if you will do plate reading of this organism, it is small white and beta hemolytic.

Species in the genus Streptococcus (formerly called diplococcus) are gram positive, and so, would meet your criteria.\n\nThis includes Streptococcus pneumoniae (a cause of lower respiratory infection pneumonia and upper respiratory infections bronchitis, laryngitis, otitis media (middle ear) and sinusitis), and Streptococcus pyogenes (a cause of rheumatic fever, scarlet fever, erysipelas, strep throat, tonsillitis, and other upper respiratory infections)

Pseudomonas (P. aeruginosa), Mycobacterium, aspergillus

check your stream water at above source soil runoff area,and compare periodic outfall testing in areas where there is an irregular out flow.you will discover a number of virulent bacteria changes with severe pollution.this is part of my study into the current worldwide MRSA infection cycles

Non of the gram negatives,so the answer will not be E.coli or Pseu....\nendospores are produced by some gram positives like Bacillus,Clostridium and sarsina \nhope it works;)

yeah, they are right, heres a site with some info:\nhttp://www.antibiotics-info.org/bact02.asp

This link has an extensive information about Aerobic and Anaerobic Bactria ( gram + & Gram -).\nIt is really a useful source:-\nhttp://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=9618450\nAlso, Gram-negative anaerobes and some of the infections they produce include the following genera:\n• Bacteroides (the most commonly found anaerobes in cultures; intra-abdominal infections, rectal abscesses, soft tissue infections, liver infection)\n• Fusobacterium (abscesses, wound infections, pulmonary and intracranial infections)\n• Porphyromonas (aspiration pneumonia, periodontitis)\n• Prevotella (intra-abdominal infections, soft tissue infections) Gram-positive anaerobes include the following:\n• Actinomyces (head, neck, pelvic infections; aspiration pneumonia)\n• Bifidobacterium (ear infections, abdominal infections)\n• Clostridium (gas, gangrene, food poisoning, tetanus, pseudomembranous colitis)

Originally classified in the 1930s as Group D Streptococci, Enterococci were officially given genus status in 1984 after hybridization studies showed a more distant relationship to Streptococci. Enterococci are gram-positive, spherical bacteria that colonize in groups or chains. They are naturally found as part of the digestive tract flora in many organisms, including humans. They are robust microbes able to tolerate relatively high salt and acid concentrations. They also seem to be able to withstand low levels of detergents, explaining why inadequate cleaning procedures can promote Enterococcus infections.\n\nWhat is now recognized as pathogenic Enterococcus was studied as early as the late 1900s. Currently, Enterococcus infections account for 12% of all nosocomial infections, second only to E. coli. An Enterococcus infection can cause complicated abdominal infections, skin and skin structure infections, urinary tract infections and infections of the blood stream. These infections can be difficult to treat, particularly in cases where the strain involved has developed resistance to several antibiotics. Infection can be life threatening in such instances, especially if the patient is already immunodeficient. \n\nThere are two species of Enterococci which cause the symptoms described above, E. faecalis, which accounts for the majority of infections (79%), and E. faecium. In a study conducted between 1995 and 1997, data were collected from over 15,000 Enterococcus isolates. Of those, less than 2% of E. faecalis were found to be resistant to ampicillin and vancomycin, whereas 83% of the E. faecium isolates were resistant to ampicillin and 52% were resistant to vancomycin. \n\nE. faecium is known to have a resistance to several types of antibiotics including quinolones and aminoglycosides. Resistance to penicillin was first observed in E. faecium in 1983, and in 1988 the first cases of resistance to the "antibiotic of last resort", vancomycin, were detected in Europe. Vancomycin-resistant strains of E. faecium were reported in the US in 1989. Resistance to several antibiotics and tolerance for adverse conditions makes E. faecium a major concern for the medical community, which has dubbed this microbe a "supergerm".

Enterobacter cloacae is a gram-negative, rod-shaped bacterium that has peritrichous flagella, measures 0.3-0.6 x 0.8-2.0 µm, is oxidase-negative, catalase-positive, and is facultatively anaerobic. The bacterium is positive for Beta-galactosidase, arginine dihydrolase, ornithine decarboxylase, citrate utilization, nitrate reduction, and Voges-Proskauer reaction. Production of lysine decarboxylase, hydrogen sulfide, urease, tryptophan deaminase and indole are all negative. Acid is produced from many carbon sources. Reactions to many of these biochemical tests may be obtained using API 20E strips (Analytab Products). In addition, E. cloacae is negative for phenylalanine deaminase and pectate degradation. \n\nEnterobacter cloacae grows well on standard bacteriological media on which yellow pigment and purple stain are not produced. Colonies are creamy tan on yeast extract-dextrose-calcium carbonate agar, and dark pink to burgundy with translucent margins on tetrazolium chloride agar. Miller-Schroth medium is useful for initial screenings because of the positive reaction (orange colonies) of E. cloacae on this medium.\n\nAlthough this bacterium is part of the normal flora of the human intestinal tract, several species cause opportunistic infections of the urinary tract as well as other parts of the body. E. aerogenes and E. cloacae are two such pathogens that do not cause diarrhea, but that are sometimes associated with urinary tract and respiratory tract infections.\n\nI just researched a couple of web sites...hope this helps you!

Yes. The singular is bacterium

a genus of gram negative bacteria that are carried as parasites by ticks and fleas among other organisms they cause many diseases one example is typhus.they are obligate parasites thus they cannot live without their host, choosing only specific organisms as hosts.

In short, bacteremic septic shock can be caused by a variety of bacterial cell components.  For gram negative bacteria, endotoxins, formyl peptides, and exotoxins are among components of the cell that can elicit such a response.  In gram positives, enterotoxins, peptidoglycans, and most especially superantigens (SPEs) will act in the same manner.  These cell components super-activate our cell-mediated immune system cascade, causing mass release of cytokines.  Cytokines are inflammatory mediators, and are ultimately responsible for the fever and septic shock effects seen.

In addition to the first answer...\nAnd there are alco nonpathogenic strains. You can see it also as red coloured colonies on old bread.\n\nOf course there are some pathogenic strains that cause nosocomial infections (hospital associated)

If you refer to Gram positive (G+)and Gram negative (G-):\nThe main difference is in the thickness of the peptidoglican layer. G- has about 10 layers of PG while G+ has more then 100 layers of PG. there are many more differences like the tichoic acid in G+ and the outer membrane and periplasm in the G-
