Summary
Nineteen bacterial strains from pigs were analyzed, revealing two distinct groups. Six strains represent a novel species, Corynebacterium suicordis sp. nov., expanding the Corynebacterium genus classification.
Area of Science:
- Microbiology
- Bacterial Taxonomy
- Animal Health
Background:
- Bacterial isolates from animal sources require thorough taxonomic classification.
- The genus Corynebacterium encompasses diverse species with varying clinical and ecological relevance.
Purpose of the Study:
- To characterize and classify nineteen Gram-positive bacterial strains isolated from pigs.
- To determine the phylogenetic and phenotypic relationships of these isolates within the genus Corynebacterium.
Main Methods:
- Biochemical profiling using the API Coryne system.
- Molecular genetic analysis including 16S rRNA gene sequencing.
- Phenotypic characterization including colonial morphology and CAMP reactions.
Main Results:
- Two distinct groups were identified among the nineteen isolates.
- Thirteen strains showed similarities to Corynebacterium striatum and Corynebacterium amycolatum.
- Six strains formed a novel phylogenetic lineage, distinct from known species, leading to the proposal of Corynebacterium suicordis sp. nov.
Conclusions:
- The study successfully classified nineteen bacterial isolates from pigs.
- A novel species, Corynebacterium suicordis sp. nov., is proposed based on phenotypic and phylogenetic data.
- This classification contributes to a better understanding of bacterial diversity in swine.
