Infectious Diseases

Infectious disease microbiomics studies how microbial communities, pathogens, resistance genes, and host–microbe interactions shape infection risk, immune response, disease severity, and outbreak surveillance.

Research Overview

Infectious disease microbiomics examines how microbial ecosystems influence pathogen colonization, immune defense, antimicrobial resistance, and clinical outcomes. Rather than studying pathogens alone, microbiomics considers the broader community context in which infections emerge, spread, and resolve.

At PanorOmics, infectious diseases are presented as a core microbiomics research area: a bridge between pathogen biology, microbial ecology, host immunity, antimicrobial resistance, outbreak surveillance, and multi-omics infection research.

Core Research Areas

Pathogen–Microbiome Interactions

Studying how microbial communities influence pathogen colonization, infection risk, immune response, and disease severity.

Microbiome and Immune Defense

Analyzing how resident microbes shape mucosal immunity, inflammation, barrier function, and host resistance to infection.

Antimicrobial Resistance

Investigating resistance genes, microbial reservoirs, and community-level patterns that influence treatment failure and public health risk.

Infectious Disease Surveillance

Using microbiome and metagenomic data to monitor pathogens, outbreaks, transmission patterns, and microbial ecosystem disruption.

Infectious Disease Microbiomics Technologies

16S rRNA Sequencing

Amplicon sequencing used to profile microbial community shifts associated with infection, colonization, and dysbiosis.

Shotgun Metagenomics

Whole-community sequencing used to detect pathogens, resistance genes, virulence factors, and functional microbial pathways.

Metatranscriptomics

RNA-based profiling used to study active microbial gene expression during infection and host–pathogen interaction.

Pathogen Genomics

Sequencing-based analysis of pathogen genomes to support strain tracking, transmission analysis, and outbreak investigation.

AI-Assisted Infectious Disease Microbiomics

Computational approaches that support pathogen detection, resistance prediction, outbreak analysis, and microbiome-based risk modeling.

Infectious Disease Microbiomics Modalities

Gut Infection Microbiomics

Studies how gut microbial communities influence gastrointestinal infection, colonization resistance, inflammation, and recovery.

Respiratory Microbiomics

Profiles airway and lung microbial communities involved in respiratory infection, inflammation, and disease susceptibility.

Hospital and Clinical Microbiomics

Analyzes microbial communities in clinical environments, patient samples, and healthcare-associated infection risk.

Antimicrobial Resistance Surveillance

Uses metagenomic data to detect resistance genes and monitor antimicrobial resistance across microbial communities.

Viral–Bacterial Microbiome Interactions

Studies how viral infections alter bacterial communities and how microbiomes influence viral disease outcomes.

Multi-omics Infection Biology

Combines microbiomics with genomics, transcriptomics, proteomics, metabolomics, lipidomics, and immune profiling.

Related microbiomic approaches such as environmental science, human health, and precision medicine microbiomics are explored across the Microbiomics Research Center.
