Anaerobutyricum-An Emerging Butyrate-Producing Genus with Potential Relevance to Host Health

Area of Science:

• Microbiology
• Gut Microbiome Research
• Host-Microbe Interactions

Background:

• Anaerobutyricum is a Gram-positive, anaerobic gut bacterium known for producing butyrate, a key metabolite for host health.
• This genus, comprising two species, is found in humans and animals, with its abundance linked to various health conditions.
• Recent interest stems from its role in intestinal homeostasis, immune regulation, and energy metabolism.

Purpose of the Study:

• To review current knowledge on Anaerobutyricum, including taxonomy, physiology, genomics, and factors influencing its abundance.
• To discuss associations between Anaerobutyricum and human health (metabolic, inflammatory, neurodegenerative disorders).
• To explore the relevance of Anaerobutyricum in animal production, particularly in pigs, concerning growth, health, and reproduction.

Main Methods:

• Literature review synthesizing existing research on Anaerobutyricum.
• Analysis of studies linking Anaerobutyricum abundance to host health outcomes in humans and animals.
• Examination of genomic and metabolic data to understand the genus's functional potential.

Main Results:

• Anaerobutyricum abundance variations are associated with human metabolic, inflammatory, and neurodegenerative disorders.
• In livestock, particularly pigs, this genus may influence growth, intestinal health, and reproductive traits.
• Current evidence is largely associative, with limited understanding of causal mechanisms and strain-level functions.

Conclusions:

• Anaerobutyricum is a promising functional genus in the gut microbiome with implications for human and animal health.
• Further research is essential to validate its role, understand host interaction mechanisms, and explore its potential as a probiotic or biomarker.
• Strain-level studies and in vivo validation are crucial for realizing the therapeutic and production potential of Anaerobutyricum.
