A new pig virus similar to Sars and Mers could threaten humans

A recently identified swine virus could potentially be a deadly threat to humans human populations, research results.

Laboratory tests show that porcine deltacoronavirus, which was first discovered in China in 201

2, leaps easily between the cells of different species, including humans.

The agent is similar to the deadly viruses responsible for Sars (severe acute respiratory syndrome) and Mers (respiratory syndrome of the Middle East), which together claimed more than 1,000 lives. In the US study of Ohio State University we participated: "We are very worried about the Emergence of coronaviruses and worry about the harm they can do to the animals and their potential to jump to humans. "

Pigs in China, swine deltacoronavirus was not associated with disease.

Then in 2014 it was found the cause of diarrhea in pigs in Ohio, USA be. Since then, the virus has appeared in pigs in various countries.

The new study, published in the Journal Proceedings of the National Academy of Sciences, shows how the virus targets a specific receptor molecule on the surface of cells lining the respiratory and digestive tracts.

Receptor receives the virus through the multifunctional enzyme aminopeptidase N access to its host.

In the laboratory, the virus binds not only to the receptor in pigs, as expected, but also in chickens, cats and humans

Ohio State University Food Research Program Scott Kenney said: "A receptor is like a lock in the door, and if the virus can detect the lock, it can enter the cell and possibly infect the host." Health News

From this point on, there is only one more question as to whether it can replicate in the cells and cause disease in these animals and humans.

So far no human is infected with porcine deltacoronavirus.

But there are disturbing similarities between the swine virus and the Sars and Mers viruses, the researchers said.

In 2002 and 2003, a Sars outbreak that began in China was linked to 774 deaths in 37 countries

that the Sars virus originated in bats before spreading to humans.

It is believed that the Mers virus has spread from camels to humans. A continuing Mers outbreak in Saudi Arabia has so far resulted in more than 1,800 cases of infections and 708 associated deaths.
