The intestinal microbiota and viral susceptibility

Area of Science:

• Microbiology
• Immunology
• Virology

Background:

• Infections often begin with pathogen invasion of mucosal surfaces, where resident microbes reside.
• The resident microbiota, particularly in the gut, is known to impact susceptibility to bacterial pathogens.
• Significant knowledge gaps exist regarding how resident microbial communities affect pathogen invasion and host immune responses.

Purpose of the Study:

• To provide a perspective on the emerging field of how the intestinal microbiota influences host susceptibility to viruses.
• To highlight the potential impact of resident microbial communities on viral pathogenesis.

Main Methods:

• This work is a perspective, synthesizing existing literature and highlighting emerging research areas.
• Focuses on the interplay between the intestinal microbiota and viral infections.

Main Results:

• Growing evidence suggests the resident microbiota plays a crucial role in host defense against pathogens.
• The mechanisms by which the microbiota influences viral susceptibility are an active area of investigation.

Conclusions:

• The intestinal microbiota is a critical factor in determining host susceptibility to viral infections.
• Further research into microbiota-viral interactions is expected to elucidate diverse mechanisms of influence.
