Extensive genetic diversity with novel mutations in spike glycoprotein of severe acute respiratory syndrome coronavirus 2, Bangladesh in late 2020.

ABSTRACT: In Bangladesh, coronavirus disease 2019 (COVID-19) has been highly prevalent during late 2020, with nearly 500 000 confirmed cases. In the present study, the spike (S) protein of severe acute respiratory coronavirus 2 (SARS-CoV-2) circulating in Bangladesh was genetically investigated to elucidate the diversity of mutations and their prevalence. The nucleotide sequence of the S protein gene was determined for 15 SARS-CoV-2 samples collected from eight divisions in Bangladesh, and analysed for mutations compared with the reference strain (hCoV-19/Wuhan/WIV04/2019). All the SARS-CoV-2 S genes were assigned to B.1 lineage in G clade, and individual S proteins had 1-25 mutations causing amino acid substitution/deletion. A total of 133 mutations were detected in 15 samples, with D614G being pre
