Vibrio cholerae (V. cholerae) causes cholera by producing cholera toxin (CT). Understanding how V. cholerae alters gut metabolism is key to developing new cholera treatments and prevention strategies.
Area of Science:
- Microbiology
- Immunology
- Metabolomics
Background:
- Cholera, caused by Vibrio cholerae (V. cholerae) and its cholera toxin (CT), remains a major global health threat, particularly impacting children under five.
- Current vaccines have limited efficacy in children, necessitating alternative preventative and therapeutic approaches.
- Recent research highlights the crucial role of host-pathogen metabolic interactions in V. cholerae infections.
Purpose of the Study:
- To review current knowledge on host-pathogen interactions during V. cholerae infection.
- To explore how V. cholerae modulates intestinal metabolism during infection.
- To discuss the implications of metabolic modulation for host immunity, gut microbiota, and pathogen transmission.
Main Methods:
- Literature review of recent advances in V. cholerae research.
- Analysis of studies focusing on host-pathogen metabolism.
- Synthesis of findings on the impact of metabolic changes on host-pathogen dynamics.
Main Results:
- V. cholerae infection significantly alters the host's intestinal metabolic environment.
- These metabolic alterations influence host intestinal immunity and the gut microbiota composition.
- Metabolic modulation by V. cholerae is critical for successful pathogen transmission.
Conclusions:
- A deeper understanding of host-pathogen metabolic interplay is essential for combating cholera.
- Targeting metabolic pathways presents a promising avenue for novel cholera interventions.
- Further research is needed to fully elucidate the complex interactions driving V. cholerae pathogenesis and transmission.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
