In the experiment, researchers from the United States found that infection with coronavirus new types of calls in monkeys the same disease symptoms as that of the man.
Detection in rhesus monkeys similar symptoms allows you to use primates to test vaccines and drugs, researchers wrote in an article published in the electronic library bioRxiv.org, reports TASS.
“We have successfully compared and compared how the disease development in humans and our monkeys. This allows you to use the latter to assess the effectiveness of different therapies and clinical measures. We have already started to check the antivirus tools and vaccines on monkeys,” said the scientists.
The first experiments on animals infected with coronavirus new type of SARS-CoV-2 were conducted by experts from the National Institute of control and prevent the spread of viral diseases in Beijing in mid-February last year. This experience did not come mice because genetically speaking they are quite far from humans. Therefore, biologists from the National Institute of Allergy and infectious diseases of the United States held the first series of experiments on the infection of rhesus monkeys with the virus SARS-CoV-2.
Thus, selecting samples of the virus from the tissues first infected residents of Washington state, scientists injected them into the body of eight healthy macaques, using all possible ways of virus penetration into the body. All primates were infected and within a day began to suffer from the typical first signs of development COVID-19-loss of appetite, blanching of the skin and lack of water in the body.
During observations, researchers found that in all animals decreased the level of hemoglobin in the blood three weeks after infection. As the doctors, by this time the virus has managed to penetrate all parts of the lungs, and also in some parts of the digestive system. This experience will allow scientists to use animals to test vaccines before testing on volunteers.
We will remind, in Russia over the past day were 71 registered a new case of coronavirus, the total number of cases increased to 438. The President of Russia Vladimir Putin instructed to ensure that all necessary units that work directly with at-risk for the coronavirus.
