What is a necrotizing infection and what are the possible causes?

My friend's mom was just diagnosed with this. She was told that a certain insect must have bitten her which caused the necrotizing infection. What type of insect is this? She's had 2 surgeries and may possibly have her hand amputated. Does any one have any information about this???

Any infection can lead to nectrotized tissue. This term simply means that the tissue is dead and has become destructive to the body. It's possible that your friend's mother was bitten by a spider, possibly a brown recluse (depending on what area of the country you live in). Sorry for your friend and her mother, but amputation may be the only way to prevent further spread of the disease, which can lead to death.  (+ info)

Is necrotizing faciitis spread through common contact?

I feel guilty but I hesitate to visit a family member whose husband died from necrotizing faciitis 7 days ago. Would she be carrying the bacteria still if she was in close contact with him before he died? Is my concern valid? I do not know anything about this disease, just that it was devistating.

Don't worry about it at all. You need to visit her, she is most likely in shock after losing her husband so suddenly, and she will appreciate that you are thinking of her.

Necrotising Fasciitis is usually caused by Group A Strep (S.pyogenes). Most of us carry some amount of this bacteria on our skin anyway. It can cause a wide range of medical problems, most of them minor and easily treatable, such as wound infections. It is very rare for it to go as far as NF, and you probably need to have some degree of immunosuppression for this to occur. NF usually starts in some sort of nick in the skin surface. It is very quickly progressive, and there is not a great risk of transmission to other family members. If she had NF, she would be dead by now, so she obviously doesn't have it.

Just go and see her. If you are really worried about it, cover any wounds you have with a waterproof covering, and watch them afterwards for any signs of infection. If there is pus, pain, or any redness, go and see a doctor. You can get antibiotics which kill the NF bacteria, but you need to get them at the first sign of infection.  (+ info)

Can I get necrotizing fasciitis from a dog lick?

My dog was licking an open cut, and also my face and mouth.

Could I have caught necrotizing fasciitis (flesh-eating disease) from his saliva?

Theoretically, you can contract NF from ANY break in the skin.

Its not a super-rare, scary, potent bug that causes it.... actually, the culprit bacteria is usually Streptococcus Pyogenes (same bug that gives us strep throat) which is a terribly common bug. Methicillin Resistant Staphylococcus Aureus (MRSA) is also a culprit, but because of it's resistance to Methicillin-based antibiotics, it is very difficult to treat.

What makes NF so devastating is the mechanism of the infection. The deep, subcutaneous tissues become infected, resulting in rapid tissue death.

So yeah, you could technically contract NF from any break in the skin.... I have heard stories of people getting it from insect bites before, even.  (+ info)

What's the difference between necrotizing fasciitis and necrotizing soft tissue infection?

I came upon the second one while researching and was wondering whether or not they are the same thing, but I'm having trouble finding information differentiating the two. Could anyone explain the differences if there are any?

They are almost the same. Necrotizing soft tissue infections refer to severe infections of the muscles, subcutaneous fat and fascia that are multifactorial in their microbial origin (which is to say that a number of both aerobic and anaerobic microorganisms contribute to the underlying etiology). Necrotizing fasciitis on the other hand is a type of necrotizing soft tissue infection that develops along the planes of the fascia and is caused by the Group A Streptococci (i.e. mostly the M1, M3 and M18 serotypes of Streptococcus pyogenes).

Therefore, necrotizing fasciitis is a type of soft tissue infection caused by a single organism. Another example in this category is myonecrosis, a soft tissue infection caused only by Clostridium perfringens.  (+ info)

How long should I keep my razor blades to avoid necrotizing fasciitis?

I have a Venus razor and the blades hardly ever get dull because my hairs are thin. The blades I have on are probably several months to a year old, but there's no rust on them and they work just fine. But last night I saw this show called "1000 Ways to Die", and this woman cut herself with an old razor blade where a flesh eating virus was growing and it killed her. So how often should I change my blades, or how can I keep them sterile because they're kind of expensive.

Trust me, you're not going to get a flesh eating virus. Even so, if you want to sterilize them, and you should, just keep them in a cup of rubbing alcohol with a sealed lid. Then, whenever your need them, just rinse them with water and use. Just make sure to clean them and put them back in.  (+ info)

What are the impacts of Necrotizing Fasciitis on technology and society?


I don't really understand the question, other than telling you that Necrotizing Fasciitis is extremely deadly.  (+ info)

How to people get Necrotizing fasciitis?


Ye as my title says.
I just been wondering.
I just wikipedia and iother sites. just tells me the treatments etc and how it realises toxins in the skin ??

But how do people get it?

You can get it from Streptococcus Pyogenes bacteria - the same thing that causes strep throat.

Getting punctured with something that carries it or having a wound that gets infected are ways that you can get it.  (+ info)

Can necrotizing facsiitis eat away at bone, as well as the skin and muscle?

This flesh-eating bacteria creates toxins that literally act almost like someone injected sulfuric acid inside your skin, and you know what sulfuric acid does to you if you touch it....it causes severe burns and even eats away at metal. The bacteria literally "eat away at the skin and the muscle" from the inside out.

Just soft tissue, not bone.  (+ info)

I need to know the life cycle of Necrotizing Fasciitis?

I've looked online but I cannot find anything on it and i need help. So what is the life cycle of the disease?
How does it infect and kill a cell?

You need to research Streptococcus pyogenes which is the bacteria present in most narcotizing fascitis cases.
Sometimes the infection with it is mild, in other cases, it is devastating. Go here:

How exactly do you catch/get necrotizing factitious?

I mean I heard its pretty rare but how would you randomly get some rare flesh eating disease...

It's necrotizing fasciitis (fass-see-EYE-tis). It's the result of a soft tissue infection and can occur after trauma or around foreign bodies in surgical wounds, or it can be idiopathic as it is in scrotal or penile necrotizing fasciitis. Idiopathic means no known cause. Specifically, it's often an infection from both anaerobic & aerobic bacteria but can be one or the other.

Insulin-dependent diabetics can set the stage for this by injecting insulin into the same place over a long period of time. Insulin can break down tissue if injection sites aren't rotated. And one of the effects of diabetes is poor circulation and impaired ability to fight infection. Some cancers can cause it. I remember a patient with angiosarcoma who had necrosis of the chest wall. Chronic vascular problems can cause it. After all, blood carries oxygen and nutrients and without them tissue dies (become necrotic). IV antibiotics that extravasate can cause tissue breakdown & necrosis. In general, conditions or drugs that impair the immune system, chronic health conditions and skin that is not intact, bowel wall injuries like gunshot wounds or surgical mishaps that cause intestinal leakage, swimming in the ocean with open wounds, wounds caused by sea animals, such as live crabs or lobsters all put some one at risk for necrotizing fasciitis.

I wouldn't call it random -- there ARE reasons.  (+ info)
