Virus amoeba

It is able to kill the amoeba - but it won't infect a human cell. However, the researchers believe that other more deadly pathogens could be locked in Siberia's permafrost. The researchers say this region is under threat. Since the s, the permafrost has retreated and reduced in thickness, and climate change projections suggest it will decrease further.

It has also become more accessible, and is being eyed for its natural resources. Prof Claverie warns that exposing the deep layers could expose new viral threats. He said: "It is a recipe for disaster. If you start having industrial explorations, people will start to move around the deep permafrost layers.

Through mining and drilling, those old layers will be penetrated and this is where the danger is coming from. He told BBC News that ancient strains of the smallpox virus, which was declared eradicated 30 years ago, could pose a risk.

Millions of people are exposed to the amoeba that causes naegleria infection each year, but only a handful of them ever get sick from it. Health officials don't know why some people develop naegleria infection while others don't. Naegleria infection causes a disease called primary amebic meningoencephalitis muh-ning-go-un-sef-uh-LIE-tis — also known as PAM.

PAM is a brain infection that leads to brain swelling and the destruction of brain tissue. The symptoms of naegleria infection generally begin within two to 15 days of exposure to the amoeba.

Initial signs and symptoms often include:. The disease can progress rapidly and typically leads to death within about five days of the start of symptoms. Seek immediate medical attention if you develop a sudden onset of fever, headache, stiff neck and vomiting, particularly if you have recently been in warm, fresh water. Naegleria infection is caused by the Naegleria fowleri amoeba, which is most often found in bodies of warm, fresh water around the world, especially during the summer months.

The amoeba is also sometimes found in soil. Treatment is advised because you can still pass on the infection to others even if you have no symptoms. The amoebae will still pass out in your stools. Also, you may still develop symptoms at a later stage. Medicines called antibiotics are needed to treat amoebic colitis. Metronidazole is the usual antibiotic that is used but tinidazole may be a good alternative. A second medicine, usually diloxanide furoate , is then used to get rid of any parasites that may still be living in your gut.

After treatment is completed, testing of a follow-up stool sample is advised to ensure that the parasites have been cleared. If you have amoebic colitis, you are at risk of becoming dehydrated. Dehydration means there is a lack of fluid in your body. It can occur if the water and salts that are lost in your stools are not replaced by you drinking adequate fluids. Therefore, drinking plenty of fluids is very important if you have amoebic colitis.

Your doctor will advise you about how much fluid and what type of fluids you should drink. If you do become severely dehydrated, you may need admission to hospital so that you can be given fluids through a vein intravenously.

Occasionally, someone who develops fulminant colitis or a hole perforation in their bowel may need surgery to remove part of their intestine. Antibiotics are also needed to treat an amoebic liver abscess. The same antibiotics are used and are usually very effective, clearing the abscess in most people. Again, a second medicine, usually diloxanide furoate, is then used to get rid of any parasites that may still be living in your gut.

If you also have colitis symptoms, drinking plenty of fluids is essential, as described above. If a very large amoebic liver abscess develops, or antibiotic treatment is not successful, surgery may be needed to drain the abscess. Surgery may also be needed if the liver abscess bursts ruptures. Simple hygiene measures can reduce the chance of becoming infected with amoebiasis and of passing the infection on to others. You can find out about these steps in the separate leaflet called Gastroenteritis.

Most people who develop amoebic colitis or an amoebic liver abscess can be successfully treated with medicines to kill the parasite and eliminate it from the gut intestines. Occasionally, treatment with medicines does not get rid of the parasite completely and symptoms can come back recur.

In rare cases, fulminant colitis can develop and this causes severe illness and carries a worse outlook. If an amoebic abscess ruptures, or infection spreads to the central nervous system, again this has a worse prognosis. If strict hygiene measures are not undertaken and precautions are not used when travelling to 'at-risk' areas, re-infection can occur.
