Of science, engineering and Planet, Scientists have found that monkeys, when infected with the corona virus, antibodies develop that can prevent them from re-infected by a second exposure to the pathogen. That would have to be able to point out that the blood plasma of recovered patients may still be able to use Covid-19-to deal with, as it says in the scientific journal “The Scientist”).

Chinese researchers have begun to study, as in the case of the new corona virus is still mainly in China, took place. Chuan Qin Institute of Laboratory Animal Sciences, Chinese Academy of Medical Sciences and wanted to know if it would be possible to get a second time be contaminated, as there were worrying reports about it came to be.

The team took to the feline corona virus in the trachea of the four adult resusaapjes, and found a short time later, a high dose of the virus in the noses and throats of the animals. The disease peaked three days after the infection. The monkeys were not hungry any more, visibly lost weight every and also had an increased rate of breathing. After five days, it was one of the resusaapjes were killed and examined. It appeared to be traces of the virus in many tissues, and his lung was inflamed.


in The serum of the other three monkeys, revealed that antibodies to contain it. That is, the protein to which the virus from entering the cells of its victim. For the first week after infection, the level of antibodies is low, but after three or four weeks, and it went up.

After a month is virus-free!

A month after the infection, the monkeys turned out to be completely virus-free, too. There have been no traces found of the nose, throat, and anus of the animals and their lungs were normal.

and they were two of the three monkeys, once again, exposed to the feline corona virus. They were, however, low-grade fever, but no symptoms at all. It was in their nose, throat, and rectum, no trace of the virus will be found. One of the two animals was then killed and the autopsy showed no traces of the virus were found in the tissue of the animal.

Antibodies

It took the researchers to conclude that the antibodies that developed after the first infection with the corona virus, the monkeys are protected against a second infection. They concluded that the reports of human patients who have a second time, the infected seemed likely to be incorrect and were the result of an error in the test. They will report their results Saturday of the scientific sitebioRxiv, which other researchers provide feedback.
