Flavobacterium macacae sp. nov., isolated from Macaca mulatta faeces

Area of Science:

• Microbiology
• Bacteriology
• Primate Microbiome Research

Background:

• The genus Flavobacterium comprises diverse bacteria found in various environments.
• Understanding bacterial diversity in animal hosts is crucial for ecological and health studies.

Purpose of the Study:

• To characterize and classify a novel bacterial strain isolated from Macaca mulatta feces.
• To determine the phylogenetic and genomic relationship of the novel strain within the Flavobacterium genus.

Main Methods:

• Isolation and cultivation of bacteria from Macaca mulatta feces.
• 16S rRNA gene sequencing for phylogenetic analysis.
• Phenotypic characterization including growth conditions, fatty acid profiles, and polar lipids.
• Genomic analysis including DNA G+C content and digital DNA-DNA hybridization.

Main Results:

• A yellow, Gram-negative, aerobic rod, strain YIM 102600T, was isolated.
• Phylogenetic analysis placed the strain within the genus Flavobacterium, closely related to F. qiangtangense and F. noncentrifugens.
• Distinct phenotypic characteristics and genomic data supported its classification as a new species.
• The DNA G+C content was 36.4 mol%, with specific major fatty acids and polar lipids identified.

Conclusions:

• Strain YIM 102600T represents a novel species, proposed as Flavobacterium macacae sp. nov.
• This finding contributes to the knowledge of bacterial species associated with Macaca mulatta.
• The study highlights the importance of polyphasic taxonomy in bacterial classification.
