Genome sequence of <i>Escherichia coli</i> H1G2: a B1 lineage isolated from the gut of Hilsa shad (<i>Tenualosa ilisha</i>) of Bangladesh

We characterized the 4.8 Mbp genome of <i>Escherichia coli</i> H1G2, a B1 lineage isolated from the gut of Bangladesh's national fish, Hilsa (<i>Tenualosa ilisha</i>). The complete assembly reveals specialized genes for sugar metabolism and adhesion, facilitating niche-specific colonization, thereby providing insights into the microbial ecology of this commercially significant species' gastrointestinal tract.
