Khosta-2: Researchers discover new virus like SARS-CoV-2 in bats


a team led by Washington State University A recent discovery was made on two viruses found in Bat In Russia at the end of 2020, very similar SARS-CoV-2,

Researchers found that proteins from viruses called Khosta-2 In addition to showing resistance, can infect human cells Antibodies monoclonal And for the serum of those who have been Vaccination Against Covid-19.

Although the search Khosta-1 more Khosta-2 did not represent any danger to humans, and more research has been presented indicating that they can, in fact, infect humans. Cells human,

In this sense, Khosta-1 posed less risk to humans, however, Khosta-2 presented “some worrying features“, it was indicated in a statement of the said institution.

Concern in front of Khosta-2

According to a study published in the journal plos pathogensKhosta-2 is sarbecovirus which in this sense belongs to the same subcategory of SARS CoV-2, Michael letkoA virologist at Washington State University said that sarbecovirus “assumes” a global health threat and for vaccination campaigns”.

In this way, the researchers verified that this virus would use spike For infected cells. caused by an infection Federation with protein receiverWhich is angiotensin-converting enzyme 2 (ACE2).

After analyzing its potency with the serum of people vaccinated against COVID-19 and those infected with Omicron, it was found that None of the antibodies tested proved effectiveSince the viral pseudotype with a recombinant spike of SARS-CoV-2, which encodes the Khosta 2 RBD protein, is shown Tolerance,

However, the new virus still lacks some of the genes that may be involved in pathogenesis in humans, that is, despite the fact that hundreds of cerbecoviruses have been discovered. Bat of Asiamajority No Huh Appropriate of infected human cells. However, there is risk that new virus to unite with another, such as SARS-CoV-2.

However, it does put on the table the importance of working on the development of discovery. new universal vaccines who guarantees protection against sarbecovirus in general, beyond just focusing on Variants Already known about the Kovid-19 virus.
