Genome sequence of Bifidobacterium canis, a sialidase-producing bacterium isolated from dogs

Sialidase is a key enzyme enabling intestinal bacteria to utilize host-derived mucin glycans and milk oligosaccharides. While sialidase has been reported in several gut bacterial genera, including Bacteroides, Clostridium, Bifidobacterium, and Akkermansia, its distribution among canine gut microbiota remains poorly characterized. We identify Bifidobacterium canis SY61 as a sialidase-producing bacterium in dogs and present its genome sequence.
