Necrotizing fasciitis, commonly known as "flesh eating bacteria," is a rare infection that can be caused by a variety of bacteria, but most commonly by group A strep. The condition destroys not only skin, but underlying muscle and fat, after entering through the body through a break in the skin or other injury…
The Centers for Disease Control and Prevention (CDC) reports that, worldwide, rates of NF increased from the mid-1980s to early 1990s" (http://www.jyi.org/volumes/volume5/issue8/features/hu.html)
Those most at risk for infection include those with "medical conditions that weaken their defenses against infections, including people with cancer or diabetes; those abusing alcohol or drugs; or those with chronic heart and lung disease" ("Flesh-eating bacteria," 2006, par. 1). As uncommon as it is for even these people to contract the condition, it is even less common for healthy people. Nevertheless, there have been some cases in which no cause could be identified (par. 1).
Necrotizing fasciitis shares symptoms of other medical conditions and does not have any unique symptoms. Thus, it can be extremely difficult to diagnose. Moreover, it is extremely uncommon, with only 500-1500 cases per year appearing estimated by the Centers for Disease Control and Prevention. "Early symptoms look like so many other things. None of the symptoms are exclusive to this disease, and since many emergency rooms have never seen a case, it is difficult to diagnose" (par. 6). ...
e pain or tenderness, especially with no apparent injury or wound, swelling, red or dusky blue rash, flulike symptoms such as diarrhea, nausea, fever, confusion, dizziness and weakness" (par.1). Symptoms follow an approximate timeline. "Within the first 24 hours, a small cut that may not necessarily look infected quickly becomes painful. Pain may also result in the same region of the body as the cut. Flu-like symptoms also begin to occur, inluding nausea, diarrhea and fever. Within three to four days, the painful area will begin to swell and may show a purplish rash plus large dark marks that will become blisters filled with a blackish fluid surrounded by bluish, white or dark mottled flaky appearance. Within four to five days, a person becomes unconscious. At this point, most people would die if medical attention is not received" (MacDonald, 1998, par. 4). Obviously, this is a rapidly progressing disease for which early detection and treatment is of paramount importance.
In one documented case of the disease, a woman who got a paper cut from flipping through a magazine was awakened that evening with throbbing pain so severe she told the doctor it "felt like her finger was going to explode" (par. 25). "Three days after the initial cut, a black dot appeared on her fingertip. Within a few hours, when she sought a doctor's care, that same black dot had grown to the size of a dime and extended down her finger" (par. 26). According to her doctor, the infection spread so rapidly that the woman might have had to have her entire arm amputated, or she could have even died.
Treatment and Prevention
Due to the rapidity with which this kind of infection spreads, it is very difficult to treat. Prevention is also difficult because the disease can be brought on by cuts and abrasions ...

The following tests were done: For Morphological test; both culturing and Gram staining was done. The samples were cultured both on MacConkey and r2a plate. The biochemical test carried out on the sample include, Catalase test. Different cleaning equipment samples that include ec1 green mop, ec2 green cloth, ec3 pink cloth, ec4 lime-yellow cloth, ec5 blue mop, ec6 red mop were compared to determine the level of contamination.
This has, in effect, necessitated the use of radical antibiotics and debridement for purposes of diagnosing and a treating it (Ahn, Mulligan, & Salcido, 2008). The disease causes severe damage to the skin as it affects the deeper layers of the skin particularly the subcutaneous tissues.
The common predisposing factors that have been recognized are host factors, such as, emotional stress, tobacco use, poor oral hygiene, and local trauma. Recently, this is also encountered in patients infected with HIV. As the name suggests, clinically, this disease is characterized by ulceration and necrosis of the interdental papillae and the free margin of the gingiva.
This is mainly due to the phenomenon of drug-resistance which some of the microorganisms manage to develop ingeniously to protect themselves and their progeny from destruction by modern drugs. So a real war of wits has been going on between these little pathogens and the mighty medical science.
VAC dressing, VAC sponge and VAC lancets are the most notable devices used in the studies. It was shown that the studies indeed support the effectiveness of VAC in wound healing. It is also effective in preventing ascetic leakage and fluid drainage after operation.
But what is the reality and undoubted fact it is increased interest to the alternative approaches in the wound healing. British researchers and health care patricians participate very actively in the process of developing this "new old" method of wound debridement.
However, for such research the author could have made the title longer to include the purpose of the conducted research. In the abstract the author has stated who were the subjects, how many and what were the major findings. Abstract is rather short, only 125 words but it does present the methods and results.
This key aids in the classification of microorganisms and to identify the causal organisms. Further, biochemical tests successfully accomplish the experimental purpose. Species identification can be accomplished by using
ost pragmatic staining also called differential staining performed to categorize microbial population into two groups the Gram positive and Gram negative organisms. The reaction displays the characteristic of the cell wall of the bacterial species. If the bacterial species
