Dr. Anan Chongkaewwatana, Director of Animal Health and Management Innovation Research Group The National Center for Genetic Engineering and Biotechnology (Biotech) posted on his personal Facebook page Anan Jongkaewwattana that a research team from Australia has developed a SARS-CoV-2 virus cell culture system capable of isolating the virus. A small quantity from the sample can come out. The research team used the cells to monitor the rapid changes in virus strains in the country. without having to spend time decoding virus genes which is expensive and time consuming The work was recently published in the journal Nature Microbiology.
After publication, the research team’s lead tweeted the results of the virus-checking system, saying: A domestically isolated BA.5 strain gives a delta-like infection character. But unlike Omikron, BA.1 simply means that without checking the genetic code, It might be confusing that Delta revived the epidemic once more.
The reason why BA.5 reinfects cells and has a delta-like shape is because BA.5 uses the same method of intracellular entry as delta, which is via an enzyme at the cell surface called TMPRSS2, while omic The other Ron, BA.1 and BA.2, did not use this enzyme. Such differences may therefore be one of the reasons why BA.1 and BA.2 do not infect lung cells as well as delta. Thus creating interest in the industry that Viruses may have non-violent properties, and since BA.4 has the same spike as BA.5 at every location, BA.4 is expected to use the same approach…it seems consistent with the results tested by the Japanese team. In hamsters, BA.4/BA.5 was more effective in rat lungs than BA.2.
