    A new bacterium, Corynebacterium appendicis, was identified from a human sample. This novel species is distinct from other Corynebacterium bacteria based on its unique biochemical properties and genetic makeup.

    Area of Science:

    • Microbiology
    • Bacteriology
    • Taxonomy

    Background:

    • Human clinical specimens can harbor diverse bacterial species.
    • The genus Corynebacterium includes various human and animal pathogens.
    • Accurate bacterial classification is crucial for diagnostics and treatment.

    Purpose of the Study:

    • To characterize a novel lipophilic, coryneform bacterium from a human clinical specimen.
    • To determine the phylogenetic and phenotypic distinctiveness of the isolate.
    • To propose a new species classification for the identified bacterium.

    Main Methods:

    • Phenotypic characterization including biochemical tests (urease, catalase, carbohydrate utilization).
    • Chemotaxonomic analysis of cell-wall components and mycolic acids.

    Related Experiment Videos

  • Molecular-taxonomic analysis using 16S rRNA gene sequencing.

    • Main Results:

    • The isolate exhibited a cell-wall chemotype IV and short-chain mycolic acids, consistent with Corynebacterium.
    • Distinct phenotypic features included positive urease and catalase tests and inability to produce acid from carbohydrates.
    • 16S rRNA gene sequencing revealed >3.0% divergence, indicating a distinct subline within the Corynebacterium genus.

    Conclusions:

    • The isolate represents a novel species, proposed as Corynebacterium appendicis sp. nov.
    • Both phenotypic and phylogenetic data support the classification of this distinct bacterial species.
    • Strain IMMIB R-3491T is designated as the type strain for Corynebacterium appendicis.
