| | Infection Control Today - 09/2003: Gram-negative and Gram-positive Bacteria |
| | Gram-negative and gram-positive bacteria both make up a significant part of the bodys defense system when they reside in the appropriate settings; taken out of their comfort zones, they can be fatal. | | | Gram positives may also be found there, but also can reside on mucous membranes such as mouth, vagina or the skin. | | | Bacteria are not just differentiated by gram-positive or gram-negative; they are also classified as aerobic those that grow in the presence of oxygen or anaerobic those that grow in its absence. |

| | As a rule of thumb (which has exceptions), Gram-negative bacteria are more dangerous as disease organisms, because their outer membrane acts as "camouflage"; the human body does not contain peptidoglycan and in fact produces an enzyme called lysozyme which attacks the open peptidoglycan layer of Gram-positive bacteria. | | | Opinions vary as to the best choice but suitable stains include safranin or fuchsin.This stains the gram negative organisms. | | | It is named after the inventor, the Danish scientist Hans Christian Gram (1853-1928), who developed the technique in 1884 to discriminate between pneumococci and ''Klebsiella pneumoniae'\' bacteria. |

| | Gram Stain Technique |
| | Gram-positive cells may become gram negative through mechanical damage, conversion to protoplasts, or aging, in which autolytic enzymes attack the walls. | | | It is used to distinguish between gram-positive and gram-negative bacteria, which have distinct and consistent differences in their cell walls. | | | The Gram stain is the most important and universally used staining technique in the bacteriology laboratory. |

| | Wall teichoic acids are found only in certain Gram-positive bacteria (such as staphylococci, streptococci, lactobacilli, and Bacillus spp); so far, they have not been found in gram- negative organisms. | | | The principal surface layers are capsules and loose slime, the cell wall of Gram-positive bacteria and the complex cell envelope of Gram-negative bacteria, plasma (cytoplasmic) membranes, and mesosomal membrane vesicles, which arise from invaginations of the plasma membrane. | | | There are two groups of bacteria that lack the protective cell wall peptidoglycan structure, the Mycoplasma species, one of which causes atypical pneumonia and some genitourinary tract infections and the L-forms, which originate from Gram-positive or Gram-negative bacteria and are so designated because of their discovery and description at the Lister Institute, London. |

| | Gram stain history and mechanisms |
| | The length of the decolorization is critical in differentiating the gram-positive bacteria from the gram-negative bacteria. | | | In addition, special stains can be used to visualize other microorganisms not readily visualized by the Gram stain, such as mycobacteria, rickettsia, spirochetes, and others. | | | The Gram staining method, named after the Danish bacteriologist who originally devised it in 1844, Hans Christian Gram, is one of the most important staining techniques in microbiology. |

| | Bandage With Built-In Sensor Can Identify Bacteria |
| | Today, if a doctor needs to identify whether a bacterial infection is of the Gram positive or negative variety, the bacteria need to be stained and examined under a microscope. | | | The sensor, the first substantial improvement in identifying Gram-positive and negative bacteria since Hans Christian Joachim Gram developed the original staining technique in 1884, is reported in the upcoming issue of the Journal of the American Chemical Society. | | | The technique currently used by doctors uses a stain that interacts with the cell walls of bacteria, changing the color of the bacteria depending on their Gram type. |
