Health Desk: Sep 08, 2020: The existence of 5 different types of coronavirus have been identified in Bangladesh by monitoring Coronavirus (SARS-CoV-2) infections, mutation rates, genetic traits, non-synonymous mutations and genomic phylogeny. It’s really hard to believe that the existence was not found in any other countries across the globe.
BCSIR Chairman Professor Dr. Md. Aftab Ali Shaikh said this while addressing Covid-19 ‘Genome Sequencing Report Awareness Meeting’ of BCSIR Genomic Research Laboratory at Bangladesh Council of Scientific and Industrial Research (BCSIR) Auditorium on Sunday morning.
Among others, Architect Yeafesh Osman, Minister, Ministry of Science & Technology Division; and researchers from the Genomic Research Laboratory were present in the event.
Professor Dr. Md. Aftab Ali Shaikh said, ‘With an aim to observe genetic diversity of COVID-19, we analyzed sequencing of the 263 genome of SARS-CoV-2. The samples were collected from 7 May to 31 July this current year. The genomes of the samples were made sequenced and were published in an international database- Global Initiative on Sharing All Influenza Data (GISAID). It was mentioned in the report that in the collected samples presence of dominating variant G 414 was found in cent percent cases. Among the 263 SARS-CoV-2 viruses, 243 GR Clad, 16 G Clad and 1 O clad were found included.’
It was also mentioned that after analyzing 263 SARS-CoV-2 genomes, mutation occurred among 737 points. Of them 358 Non-Synonymous Amino Acid replacements occurred. So far, the rate of SARS-CoV-2 mutation in per sample, is 7.23 across the world. Which appeared 12.6 in Bangladesh. That means, compared to any other countries, SARS-CoV-2 is swiftly changing its shape in Bangladesh.
53 non-synonymous ammonia out of 103 nucleotide nutation, in the spike protein gene occurred much replacement, of them 5 is of different type. It was not held in any other countries across the globe. During the sample collection period, repetition of 4 mutations appeared in cent percent cases.
The BCSIR chairman said that besides SARS-CoV-2 virus’s source, nature of motion and spread, scientists across the globe have been researching on medicine and Covid-19 vaccine. Bangladesh also took a project to build SARS CoV-2 virus genome sequencing. Genome Sequencing Laboratories took a plan to establish a total of 300 virus sequencing projects under the 8 divisions in Bangladesh.
Research findings will be published in the research papers of international journals. At the same time, this report was sent to 50 Covid-19 vaccine makers across the world that includes, China, US, Oxford University.
