Gram Negative Infection

Gram Negative Infection General Information

Gram negative microorganisms were first discovered by a pathologist and pharmacologist in 1884 when he published his research about how the bacterial cells “take up” and retain specific stains. For example, the bacteria causing Gram Negative Infection turns pink in the moment when it is exposed to a certain special stain. Some examples of organisms leading to the appearance of the medical condition called Gram Negative Infection that we can offer are: shigella, Escherichia coli, salmonella and pseudomonas. On the other hand, the gram positive bacteria are: clostridium, staphylococcus, anthrax and streptococcus.These types of bacteria are impermeable although the gram negative organisms have a major virulence factor that is actually a component of the cells wall, a part of the outer membrane. This factor is more commonly known as endotoxin. The bacteria provoking the occurrence of Gram Negative Infection are found most abundantly in the human organism, especially in the individual’s gastrointestinal tract where proteus organelli and shigella live. Along with the gram negative bacteria, some other gram positive organisms also populate that area. These organisms that are responsible with the appearance of so many medical conditions do fine in a moist environment that has the temperature of the human body due to the fact that have preference for the conditions inside a human body. A normal amount of humidity and 37oC represent the best conditions for these organisms to develop and live. The microorganisms of this kind can also develop in very hot conditions (in over 200oC), at an acid pH.

Gram Negative Infection Symptoms

Gram Negative Infection caused by bacteria as Escherichia coli shigella, proteus organelli, salmonella and pseudomonas can develop anywhere in the human body, but the most common are the infections of the skin, oral and dental areas, inside the abdominal regions, females genital tract. There were some cases of bone and soft tissue infections. Depending on which area is affected, the signs and symptoms range from headaches, high fever, tiredness, sweating, confusion, fast breathing, chills, or increased rates of the pulse to more serious manifestations (for example loss of consciousness due to the low pressure of the blood) that may indicate the presence of extremely serious infections in the organism. These may lead to severe health problems if the infection is not treated properly in time with the best treatment option (the one that fits with the patient’s demands and needs). Gram Negative Infection can also cause problems with the respiratory tract, for example: pain felt around the nose, eyes and forehead and colored nasal discharge as a result of a bacterial sinusitis. The throat may become swollen and red. Trouble with swallowing may also appear and pus or white streaks on the tonsils can often appear. Bronchitis and pneumonia are represented by signs and symptoms as difficulty when breathing and coughing. If the infections occur in the digestive tract, the patients will complain of diarrhea, nausea and vomiting that are usually caused by food-borne bacterial diseases. Pain when urinating, dribbling, hesitation and interruption when urinate appear when there is an infection of the urinary tract.

Gram Negative Infection Treatment

If you start experiencing any of the symptoms and signs listed above that indicate Gram Negative Infection, then we strongly advise you to call 911 (or another local emergency number), your health care provider or to go to the emergency room. An infection of this kind can be very serious and dangerous for the patient’s health status and needs immediate medical professional intervention. The particular characteristic of Gram-negative bacteria is the structure that the organism’s outer membrane has. This unique aspect is responsible with the occurrences of Gram Negative Infection because the membrane’s outer leaflet contains a multitude of lipopolysaccharides that have a lipid portion that acts as an endotoxin (a natural compound that is found inside pathogens, for example bacteria and has a level of toxicity; this structural component is not secreted by the bacteria, being actually released when the microorganism is lysed). Gram Negative Infection appears if the endotoxin has entered in the human circulatory system. Starting from this site, it causes many toxic reactions, for example low pressure of the blood, high temperature of the body and respiration rates. Usually, this may lead to fatal complications, such as an endotoxic shock. The outer membrane has the role of protecting the bacteria from detergents, several antibiotics and dyes that could have damaging effects upon the cell wall, also known as peptidoglycan or inner membrane. This outer membrane helps the bacteria resist to penicillin or lysozyme (an enzyme that can damage the walls of different various bacterial cells).

Decades of studies brought alternative drug therapies. These new methods are efficient in the combat against that protective outer membrane that some pathogenic Gram-negative microorganisms have. Because the microbial world is very diverse, some antibiotics are also used to treat medical conditions as Gram Negative Infection. There are some antibiotics that are called “broad spectrum” due to the fact that they can destroy both gram-positive and gram-negative bacteria, for example Imipenem or Miripinem, as well as many more other microorganisms. On the market are more narrow-spectrum drugs that are effective only on gram-negative, such as Aztrianam or gram-positive bacteria such as Lanazolid or Vancomycin. This last one involves in the synthesis of the cell wall. Some examples of alternative medicine therapies are based on the antibiotic called Ampicillin and on Lysozyme combined with EDTA (the abbreviation of the chemical substance ethylenediaminetetraacetic acid, a chelating agent). There are also other several drugs that offer efficient results when dealing with Gram Negative Infection and some examples that we can offer are: nalidixic acid (prescribed as Wintomylon and Neggram, effective also against Gram-positive bacteria), streptomycin (an antibiotic that belongs to the a class of drugs known as aminoglycosides and is derived from an actinobacterium called Streptomyces griseus) and chloramphenicol (a bacteriostatic antimicrobial that comes from another bacterium, called Streptomyces venezuelae discovered by D. Gottlieb in 1949).
