An international team of molecular biologists conducted a comparative analysis of the genomes of close relatives of the coronavirus SARS-CoV-2, and found that his ancestor was separated from the total tree of evolution of viruses of bats of about 40-70 years ago, reported in the scientific journal Nature.
According to scientists, among podkovonos bats for several decades, circulating the virus, related to SARS-CoV-2. However, they are very versatile.
British researchers from the University of Edinburgh studied the genomes of six dozen modern relatives of SARS-CoV-2 among other coronaviruses. It was found that they all circulate among bats in southern China for 50 years.
Scientists hope that in the near future they will be able to analyze new samples of coronaviruses of bats who live in the Chinese provinces of Yunnan and Hubei.
Comparative analysis of the genomes of SARS-CoV-2 should help to clarify the time interval of appearance of the ancestor of the pathogen COVID-19, made by British researchers.
