Advanced Microbial Strain Typing Using Whole Genome Sequencing: Poster Presented at PDA Microbiology Conference 2025.

Area of Science:

• Microbiology
• Genomics
• Bioinformatics

Background:

• Microbial identification and strain typing are crucial for pharmaceutical product safety and regulatory compliance.
• Traditional methods like PFGE and MLST have limitations in scalability and resolution.
• Next-generation sequencing (NGS) and whole-genome data enable advanced analysis but often require species-specific optimization.

Purpose of the Study:

• To investigate the potential of conserved bacterial genes as universal markers for prokaryotic strain typing.
• To compare the efficacy of conserved gene typing with species-specific methods.

Main Methods:

• Analysis of conserved genes across multiple bacterial species.
• Comparison of strain typing results obtained using conserved genes versus species-specific housekeeping genes.
• Evaluation against species with no established typing methods.

Main Results:

• Conserved genes successfully distinguished bacterial strains.
• The universal gene approach demonstrated comparable performance to established species-specific schemes.
• This method proved effective even for species lacking prior strain typing protocols.

Conclusions:

• Conserved genes offer a viable strategy for universal prokaryotic strain typing.
• This research paves the way for a rapid, species-independent genomic solution for microbial typing.
• The developed method can enhance microbial characterization in pharmaceutical microbiology and beyond.
