Many trillions of microbes—too small to be seen by the naked eye--live in our guts and elsewhere on our bodies.  These microbes contribute to health by helping with digestion, guiding growth of our immune systems, and shouldering out invading pathogens.  People differ greatly in the composition of their microbiota, influencing us each in unique ways.  The human microbiota has been reported to influence risk of heart disease, cancer, autism, obesity, inflammatory bowel diseases, and many other disorders.

The PennCHOP Microbiome Program promotes research in this exciting area, and offers opportunities for public participation through philanthropy.


We are happy to announce three new services for microbial analysis
These include high throughput screening of microbial metabolites, proteomic analysis of microbiome samples, and long-read single-molecule sequencing to determine bacterial genome sequences.  Please click here for more information.

Grant Opportunity
"Advancing Translational and Clinical Probiotic/Prebiotic and Human Microbiome Research (R01 Clinical Trial Optional)"

Sponsored by: National Institutes for Health
The purpose of this funding opportunity announcement (FOA) is twofold: 1. to accelerate translational and clinical Phase I and II a/b safety and efficacy studies for substantiating measurable functional benefits of probiotic/prebiotic components and/or their combinations; and; 2. to understand the underlying mechanisms of their action(s), and variability in responses to these interventions.
