# Genome sequence of Bifidobacterium canis SY61, a sialidase-producing bacterium isolated from canine feces

## TL;DR

This paper presents the complete genome sequence of Bifidobacterium canis SY61, a sialidase-producing bacterium from dog feces, enhancing understanding of canine gut carbohydrate metabolism.

## Contribution

The study provides the first gap-free genome sequence of Bifidobacterium canis SY61, a sialidase-producing canine gut bacterium.

## Key findings

- Bifidobacterium canis SY61 produces sialidase, which helps in utilizing host mucin glycans and milk oligosaccharides.
- The genome sequence of SY61 is the first complete genomic resource for Bifidobacterium canis.
- The study advances understanding of carbohydrate metabolism in the canine intestinal microbiota.

## Abstract

Sialidase facilitates the utilization of host mucin glycans and milk oligosaccharides by intestinal bacteria. We identified Bifidobacterium canis SY61 as a sialidase-producing canine gut bacterium and sequenced its genome, providing the first gap-free genomic resource for this species and advancing our understanding of carbohydrate metabolism in the canine intestinal microbiota.
