Anaerostipes caccae as Next Generation Probiotics
Background A. caccae for Health Services Products FAQs Resources
Introduction of A. caccae
Anaerostipes caccae (A. caccae) was originally one of the major bacteria that produced butyrate through lactic acid metabolism in the adult gut. It is now considered to have health effects on humans. Creative Biolabs is a multidisciplinary, qualified & experienced team. We are 100% dedicated to live biotherapeutic products (LBP) development. We will work with you as part of your team to provide timely and effective solutions.
Introduction of A. caccae
A. caccae is a member of the Clostridial cluster XIVa Firmicutes bacterial group. The organism was first described in 2002 after being isolated from human feces. A. caccae is an obligate anaerobe. Isolates are Gram variable, non-motile, and rod-shaped bacteria with the ability to produce butyrate from glucose metabolism. Individual cells are 0.5-0.6 µm in width×2.0-4.0 µm in length and occur in chains of up to 4 cells. On Colombian blood agar, it forms white-opaque colonies that are round, smooth, shiny, sticky, and no hemolysis. The strains are catalase and oxidase negative. Butyrate, acetate, and lactate are the main products of glucose metabolism. The DNA G+C content is 45.5-46.0 mol%.

Allergic Responses

Microbiome-based treatments can be considered a potential treatment for food allergies. Scientists colonized germ-free mice with feces from healthy or cow's milk allergic (CMA) infants. They found that germ-free mice colonized with bacteria from healthy, but not CMA, infants were protected against anaphylactic responses to a cow's milk allergen. Differences in bacterial composition in human donors and transplanted mice separate the healthy population from the CMA population. To further study the role of A. caccae in gene expression regulation, mice were then administered with A. caccae. A. caccae were able to reduce the expression of T2 dependent, antibodies, Acot12 expression as well as cytokine responses IL-13 and IL-4, which promoted oral tolerance towards cow's milk allergy. This opens new perspectives for the treatment of food allergies in humans.

Cancer

In recent years, intestinal flora has been found to play an important role in the regulation of anti-cancer immune and therapeutic responses. Scientists selected a mix of four Clostridiales species, namely Roseburia intestinalis, Eubacterium hallii (Anaerobutyricum hallii), Faecalibacterium prausnitzii, and A. caccae for investigations in murine models of colorectal cancer (CRC). Oral administration of a mixture in mice could prevent or even successfully treat CRC as an independent treatment. This effect depended on intratumoral infiltration and activation of CD8+ T cells. In a therapeutic setting, as well as R. intestinalis and A. caccae as individual single strains, were successful in decreasing the CRC tumor burden. Their findings provide a strong preclinical foundation for exploring gut bacteria as novel stand-alone therapy against solid tumors.

FAQs
What are the main metabolic products of A. caccae and their significance in human health?
A. caccae primarily metabolizes glucose to produce butyrate, acetate, and lactate. Butyrate is particularly notable for its potential benefits in regulating immune responses and protecting against colon cancer.
How is A. caccae isolated and identified for research purposes?
A. caccae is isolated from human feces and identified through a combination of phenotypic methods like colony morphology on blood agar and genotypic methods, including 16S rRNA sequencing. Advanced imaging techniques and biochemical assays are also employed to confirm its identity.
Can A. caccae be used in faecal microbiota transplants (FMT)?
While A. caccae is a component of the gut microbiota and contributes to butyrate production, its specific use in FMT is still under research. FMT typically involves a broader spectrum of microbial communities aimed at restoring gut microbiota balance.
What in vitro tests are conducted to assess the probiotic properties of A. caccae?
Several in vitro assays are utilized, including microbial aggregation and hydrophobicity assays to evaluate the adherence capability, survival assays under simulated gastrointestinal conditions, and antimicrobial activity assays to assess its efficacy against pathogens.
How does A. caccae interact with other gut microbiota in terms of cross-feeding?
A. caccae participates in cross-feeding interactions within the gut microbiome, particularly with other butyrate-producing bacteria. It can utilize intermediate metabolic products produced by other microbes, contributing to a complex butyrogenic network that supports gut health.
