Anaerostipes hadrus as Next Generation Probiotics

Since its original isolation, evidence is growing to support the significance of strains belonging to Anaerostipes hadrus (A. hadrus) within the human GI tract. Creative Biolabs is a CRO company focused on live biotherapeutic products (LBP) development, we offer our technical expertise and experience to provide traceable, customizable solutions.

Introduction of A. hadrus

A. hadrus has been estimated to represent 2% of the total microbiota in a healthy human colon. Anaerostipes hadrus is a Gram-positive bacterium from the genus of Anaerostipes which has been isolated from human faeces. The cells are rods, non-motile, and are approximately 3×0.5 μm in size. Endospores were not observed. Anaerostipes hadrus is a bacterium known for its ability to produce butyric acid. Butyrate has been shown to have a positive effect on gastrointestinal homeostasis because it promotes intestinal epithelial cell growth, increases tight junction protein expression, and acts as an anti-inflammatory agent. Therefore, butyrate-producing bacteria are generally considered to promote health.

The Benefit of A. hadrus

  • Reduce Metabolic Risk

Research on gut microbiota genomic structural variants (SVs) uncovered that a region in A. hadrus that encodes a composite inositol catabolism-butyrate biosynthesis pathway is associated with low host metabolic risk assessed by BMI, waist-to-hip ratio, etc.

  • Irritable Bowel Syndrome (IBS)

A. hadrus-like bacteria were found to be more abundant in the feces of healthy controls in our study concerning diarrhea-predominant IBS. The study was based on high-throughput 16S rRNA gene sequencing, and the health-associated phylotype was referred to as Ruminococcus torques phylotype 93%. A. hadrus-like bacteria were present also in IBS subjects but in significantly lower numbers than healthy controls.
