Probiotic News and Research

RSS

Probiotics are live microorganisms thought to be healthy for the host organism. According to the currently adopted definition by FAO/WHO, probiotics are: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host".

Research Decodes How Gut Microbes Process Plant-Based Nutrients

Plant-based diets are good for you. They promote gut, immune, metabolic and cardiovascular health, in part by cultivating a diverse community of intestinal bacteria.

Engineered Probiotic Bacteria Deliver Immune Therapy Directly Into Pancreatic Tumors

Cancer immunotherapies have transformed treatment for many cancers, but pancreatic cancer remains especially difficult to treat. One major reason is that pancreatic tumors often create a "cold" tumor microenvironment, where the tumor prevents immune cells from mounting a strong attack.

Gut Microbiome Signatures Correlate With Clinical Efficacy in Immunotherapy Outcomes

Cancer remains notoriously difficult to treat, partly because tumors co‑opt their surrounding environment, including the resident microbiota, to evade immune surveillance and resist conventional therapies.

Research Links Bifidobacterium animalis Metabolites to Improved Anti-Tumor T Cell Immunity

Immune checkpoint inhibitors like anti-PD-1 have transformed melanoma treatment, yet more than half of patients fail to respond or eventually develop resistance. The tumor microenvironment and the gut microbiome are increasingly recognized as critical determinants of immunotherapy outcomes.

Scientists Reveal How Surface Acids Prevent Bacteria From Blobbing

Researchers have discovered how acids on the surface of bacteria give these microscopic organisms their characteristic "rod" shape-by keeping an enzyme at bay that would otherwise turn the cylindrical cells into shape-shifting blobs.

Microbes Switch Functional States Without Genetic Mutations to Withstand Stress

Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have discovered that many gut bacteria use a flexible survival strategy to withstand disruptions such as antibiotics and diet changes.

New MIND Tool Enables Precise Control of Complex Microbiomes

University of California San Diego researchers have developed a new tool for understanding and modifying any microbiome, including the human microbiome.

Engineered Bacteria Deliver Targeted Anticancer Therapy in Tumors

Every year, millions of people are diagnosed with cancer globally; however, current treatments are limited by disease complexity.

New Enzyme and Bacteria Unlock Efficient Production of Healthy Sweetener

From saccharin in the 19th century to stevia and monk fruit in the 21st, researchers and the food industry have long sought a sweetener that delivers the taste of sugar without its drawbacks-excess calories, tooth decay, and heightened risk for obesity, insulin resistance, and diabetes.

Kefir-Derived Bacteria Show Potential to Reverse Age-Related Immune Decline

The process of aging is associated with a decline in immune functions and persistent low-level inflammation.

Study Uncovers Hundreds of New Viruses Living Inside the Gut Bacteria

Hundreds of new viruses living inside bacteria within our gut have been discovered in an international study led by Professor Jeremy J. Barr from Monash University's School of Biological Sciences and Associate Professor Sam Forster from Hudson Institute of Medical Research.

Targeting the Oral Metagenome to Boost Healthy Bacteria

Professor Zhang, a chemical and biomolecular engineering professor at UC Berkeley, is working to distinguish between the healthy and unhealthy bacteria in the human mouth. Her goal is to promote a probiotic oral microbiome by increasing the population of beneficial bacteria.

Amino Acids as Key Mediators in the Tumor Immune Dialogue

The tumor microenvironment is not just a site of cancer growth—it is a high-stakes metabolic contest where tumor and immune cells vie for limited resources.

Gut Bacteria Breakthrough Could Help Fight Chronic Diseases

An international research team led by scientists from the University of Copenhagen has discovered a common gut bacterium that lowers body weight and blood sugar while increasing bone density.

Gut Bacteria Adapt to Local Diets Offering Hope for Personalized Probiotics

Probiotics are emerging tools used by neonatal intensive care units to promote healthy outcomes and prevent intestinal diseases such as necrotizing enterocolitis.

Gut Microbes May Help Remove Toxic Forever Chemicals from the Body

Scientists have discovered that certain species of microbe found in the human gut can absorb PFAS - the toxic and long-lasting 'forever chemicals.'

New Study Maps How Pesticides Alter Human Gut Bacteria

While emerging evidence suggests pesticides can be toxic to the mix of microorganisms in the digestive system, a new study is the first to map changes to specific gut bacteria based on interactions between human microbes and insect-killing chemicals observed in the lab and an animal model.
