Scientists Wake Virus After 30,000 Year Slumber

Wakening the long-dormant virus serves as a warning that unknown pathogens entombed in frozen soil may be roused by global warming, the scientists said.

The virus, Pithovirus sibericum, was found in a 30-metre-deep sample of permanently frozen soil taken from coastal tundra in Chukotka, near the East Siberia Sea, where the average annual temperature is -13.4 degrees Celsius.

The team thawed the virus and watched it replicate in a culture in a petri dish, where it infected a simple single-cell organism called an amoeba.

Radiocarbon dating of the soil sample found that vegetation grew there more than 30,000 years ago, a time when mammoths and Neanderthals walked the Earth, according to a paper published in the US journal Proceedings of the National Academy of Sciences ::::

Pithovirus sibericum is – on virus scale – a behemoth, it contains 500 genes, whereas the influenza virus has only 8, it’s the first in a new category of viral giants, known as Megaviridae. The virus gets its name from the ancient Greek “pithos,” or a jar, due to it’s amphora shape.

At 1.5 millionths of a metre, it is so big it can be seen through an optical microscope, rather than a more powerful electron microscope. Unlike the flu virus, though, P. sibericum is harmless to humans and animals, and only infects a type of amoeba called Acanthamoeba, according to the discovering scientists.

The work shows that viruses can survive being locked up in the permafrost for extremely long periods, France’s National Centre for Scientific Research said in a press statement.

“It has important implications for public-health risks in connection with exploiting mineral or energy resources in Arctic Circle regions that are becoming more and more accessible through global warming,” the scientist said in their statement. “The revival of viruses that are considered to have been eradicated, such as the smallpox virus, whose replication process is similar to that of Pithovirus, is no longer limited to science fiction. The risk that this scenario could happen in real life has to be viewed realistically.”

RELATED! The Rise and Rise of Allergies, Microbial Deprivation – The Hygiene Hypothesis – Diverse Human Gut Flora

The Rise and Rise of Allergies, Microbial Deprivation - The Hygiene Hypothesis - Diverse Human Gut FloraI consider myself a germaphobe, the thought of unseen creepy crawlies does serious damage to my mind, bleach is my best friend.

I’ve fallen in love with antibacterial wipes, vinegar, indeed anything that will KILL microbes on surfaces anyplace near me. I grow a huge smile every time I see Asian tourists strolling the streets in surgical face masks, are we overreacting?

It turns out I might be overreacting, scientists reckon that some germs are good? I must point out that Hygiene – as used in this post –  has little relationship with ‘hygiene’ in the usual meaning of the word. The term ‘hygiene hypothesis’ is unfortunate, as it is misleading. A better term would be Microbial Deprivation Hypothesis.

Our immune systems are our single most important line of defense against infection.

The bacteria and germs that surround us, some of these microbes can be nasty, really nasty, causing food poisoning, colds, a variety of other infections as well as diseases.

It is perhaps the ones inside that we need worry most about though, many researchers are now focusing on dysfunctional colonies of microbes within human beings for causes to disorders such as asthma, MS and autism, including disorders previously believed to be entirely brain based like epilepsy, depression and even my favourite, Bipolar Disorder.

I must warn, this is an opinion piece, it is based on several hypotesis – of others – a little thought, possibly some hyperbole and a little wishful thinking, it is meant entirely for thought provocation :: Read the full article »»»»

Government Agency Warns Infants Diagnosed with ParechovirusAustralian GPs are being urged to be on the look out for a new virus, called Parechovirus – HPeV – that affects infants and has not been seen in Australia before.

About 20 babies have been diagnosed with the gastro and respiratory virus, which usually only causes fever, rash and diarrhoea but in severe cases can develop into hepatitis or encephalitis.

New South Wales Health – NSWH – says all 20 cases of HPeV have so far been in children aged under 16 weeks.  Parents and doctors should be on the lookout for symptoms.

HPeV is a ubiquitous virus that is transmitted from person to person via direct and indirect routes. It is the cause of paralytic poliomyelitis, a disease that has been eradicated from most western nations :: Read the full article »»»»

Australian Health Authorities on the Lookout for SARS Like VirusAustralian authorities are watching a virus, which has killed almost half of the people who have contracted it, as it spreads across the Middle East and Europe. The World Health Organisation first identified novel coronaviris (NCoV) in September, but experts say there is no signs of it in Australia.

The virus is part of the same disease family as Severe Acute Respiratory Syndrome – SARS –  A total of 11 people have contracted NCoV in Britain, Germany, Saudi Arabia and Jordon. Five sufferers have died.

Between November 2002 and July 2003, an outbreak of SARS in Hong Kong came close to being classified a pandemic, with 8,273 cases and 775 deaths worldwide – 9.5 per cent fatality – according to the World Health Organization. Within weeks, SARS spread from Hong Kong to infect individuals in 37 countries.

University of Queensland virology professor Paul Young says local health authorities are on alert because there is evidence of person-to-person transmission :: Read the full article »»»»
