Taxonomic analysis reveals a novel genus and species in human clinical samples, indicating a distinct bacterial lineage within the Bifidobacteriaceae family.

Key Points

To resolve the taxonomic position of 12 clinical bacterial isolates historically assigned to the genus Bifidobacterium.
Examined 12 clinical isolates collected between 1978 and 2005 from human sites (urine, blood, urethra, oral cavity, tonsil, and abscesses) across Belgium, Sweden, and Norway.
Performed repetitive DNA element-based PCR fingerprinting, 16S rRNA gene sequencing, partial hsp60 sequencing, and DNA-DNA hybridization.
Characterized phenotypic traits, including aerobic growth tolerance and acid production from various carbohydrates.
16S rRNA gene sequence similarities positioned the isolates closest to Parascardovia denticolens (93.0–93.2%) and Scardovia inopinata (92.9–93.1%), denoting a novel genus within Bifidobacteriaceae.
DNA-DNA binding among tested strains ranged from 89% to 100% with a DNA G+C content of 47.3–48.3 mol%, supporting classification as a single novel species named Alloscardovia omnicolens.
Isolates exhibited aerobic growth on agar and produced acid from L-arabinose, raffinose, salicin, and D-xylose, distinguishing them phenotypically from related taxa.
