Mutation typically refers to the property of a virus to undergo changes when it multiplies and the virus may develop some new strains after it replicates.
Emergency use for COVID-19 vaccine to depend on trial data; roll-out of FELUDA test expected soon: Vardhan
Presently COVID-19 vaccines are in various stages of phases 1, 2 and 3 of human clinical trials, the results of which are awaited, Vardhan said during an interaction with his social media followers.
The 'antisera' has been developed by the Indian Council of Medical Research (ICMR) in collaboration with a Hyderabad-based bio-pharmaceutical firm.
Named after Satyajit Ray's famed detective, the Feluda test, which is priced at Rs 500 and can deliver a result in 45 minutes, is able to differentiate SARS-CoV-2 from other coronaviruses.
The generated high-powered microscopic images show a large number of the virus particles on human respiratory surfaces, ready to spread infection across tissues, and to other people.
The only thing that can be said with any degree of uncertainty is that antibodies is a sign that the person has already been infected with the novel coronavirus, the scientists said.
According to the team of researchers, the novel coronavirus (SARS CoV-2) is composed of inner nucleic acid which is covered with surface spike glycoprotein.
Conducted between August 1 and August 7, the survey, second in the city, showed that 29.1 percent of the population in the national capital has now developed antibodies against SARS CoV-2.
Preliminary results from this research were used to facilitate the start of clinical trials of the vaccine in humans, the researchers noted.
The findings, published in the journal Nature Microbiology, suggest that the novel coronavirus, SARS-CoV-2, is likely to have evolved from its most closely related bat viruses decades ago.
No evidence for transmission from pet animals yet, researchers said.
In the current study, published in the journal Science, the scientists designed a new version of this protein which can be produced up to 10 times more in cells.
Seventeen virus cultures have been established from swab samples originating from different locations of the country with varying virus loads by the ILS.
The virus may then be exposed to the river water containing antiviral drugs, inducing antiviral selective pressures and mutations in the virus leading to antiviral drug resistance.
The SARS-CoV-2 virus that causes the dreadful infection is extremely resilient and can survive on surfaces much longer than expected.
