Implication

Taxonomic analysis demonstrates the novel bacterial species Bacteroides intestinalis isolated from human faeces, highlighting the uncharacterized diversity of the human gut microbiota.

Key Points

  • To isolate and characterize novel anaerobic bacterial strains discovered in human faecal samples.
  • Cultured five strains of Gram-negative anaerobic rods from human faeces using a polyamine-deficient medium.
  • Performed 16S rRNA gene sequencing, DNA G+C content determination, fatty acid profiling, biochemical assays, and DNA-DNA hybridization on type strain 341T.
  • Strain 341T exhibited <95% 16S rRNA gene sequence similarity to recognized Bacteroides species, with 44 mol% DNA G+C content and 32.0% anteiso-C15:0 fatty acid.
  • DNA-DNA hybridization and biochemical tests distinguished strain 341T from its closest relatives, Bacteroides uniformis and Bacteroides helcogenes, defining Bacteroides intestinalis sp. nov.
