New tool enables study of SARS-CoV-2 mutant spectrum by ultrasequencing SARS-CoV-2 genome is three times larger than influenza genome. Both consist of NRA molecules that mutate when replicate. It is essential to know its mutant spectrum, in other words, its "fingerprints", to achieve an appropriate treatment that reduces its infectivity -the capacity of pathogens to invade organisms and cause infections-, since its composition of variants could determine how infection would develop in each patient. Researchers of the University of Malaga (UMA) will be able to examine the depth of these spectra by genetic ultrasequencing techniques thanks to the innovative system they have designed: "QuasiFlow", a tool that enables the analysis of variants present in each patient individually.
