Main Article

Figure 2

Phylogenic analysis of bat reovirus detected from cases of acute respiratory disease and encephalitis in humans, Bangladesh, 2022–2023. Sequencing of the partial S1 segment showed that Pteropine orthoreovirus from patients in Bangladesh (bold) clustered with 99.3%–100.0% average nucleotide identity (ANI). Bangladesh PRV showed ≈96% ANI with the Indonesia/2010 strain detected from large flying-fox (Pteropus vampyrus) in Indonesia (GenBank accession no. KM279386.1) and ≈85% ANI with the Nachunsulwe-57 strain detected from an Egyptian fruit bat (Rousettus aegyptiacus) in Zambia (accession no. LC619335) in 2018. GenBank accession numbers are indicated for reference sequences. Scale bar indicates nucleotide substitutions per site.
