Bacteriophage functional genomics and its role in bacterial pathogen detection

Area of Science:

• Microbiology
• Genomics
• Public Health

Background:

• Bacterial infectious diseases pose significant global health risks.
• Bacteriophages contribute to bacterial pathogen emergence via horizontal gene transfer, as seen in the 2011 Escherichia coli O104:H4 outbreak.
• Advances in functional genomics are vital for understanding pathogen virulence and developing diagnostics/therapeutics.

Purpose of the Study:

• To review functional genomics of bacteriophages, focusing on genome sequencing, annotation, prophage identification, and the infection process.
• To highlight the importance of phage genomics in bacterial detection and diagnostics.
• To bridge the gap between increasing phage sequence data and limited functional studies.

Main Methods:

• Review of existing literature on bacteriophage functional genomics.
• Analysis of phage genome sequencing and annotation data.
• Examination of prophage identification in bacterial genomes.
• Discussion of genomic, transcriptomic, and proteomic approaches to study phage life cycles and host interactions.

Main Results:

• Despite numerous phage sequences, functional genomics studies remain limited.
• Phages encode virulence and adaptive traits, influencing bacterial pathogenicity.
• Genomic information from phages and prophages can be utilized for bacterial detection.

Conclusions:

• Functional genomics of bacteriophages is essential for understanding bacterial infectious diseases.
• Further research is needed to fully elucidate phage roles in virulence and host adaptation.
• Phage genomic data offers promising avenues for developing novel diagnostic tools.
