Phageome Analysis of Bifidobacteria-Rich Samples

Area of Science:

• Microbiology
• Virology
• Metagenomics

Background:

• Bifidobacteria are key early colonizers of the infant gut microbiome.
• Bacteriophage activity is a significant factor influencing Bifidobacteria populations.
• Understanding host-virus interactions is crucial for gut health.

Purpose of the Study:

• To provide technical instructions for analyzing the virome of Bifidobacteria-rich samples.
• To facilitate metagenomic studies of bacteriophage-Bifidobacteria interactions.
• To aid researchers in characterizing the gut virome in specific contexts, such as infant fecal samples.

Main Methods:

• Metagenomic sequencing of viral DNA extracted from fecal samples.
• Bioinformatic analysis pipelines for virome assembly and taxonomic profiling.
• Focus on techniques applicable to Bifidobacteria-dominated environments.

Main Results:

• The chapter provides a framework for comprehensive virome analysis.
• It enables the identification and quantification of bacteriophages targeting Bifidobacteria.
• Methodology is presented for samples rich in Bifidobacteria, like those from infants.

Conclusions:

• Metagenomic analysis of the virome is essential for understanding Bifidobacteria ecology.
• This guide offers practical steps for researchers studying gut bacteriophages.
• Characterizing the virome aids in deciphering host-microbe-virus dynamics in the human gut.
