Gut Microbiome

Our intestine is populated by billions of beneficial organisms. Their number far outnumbers the cells in our entire body. These microbes can help us remain healthy. Dr. Michail’s past research contribution helped us understand the gut microbial profile in healthy children as well as describe the gut microbiome in several digestive disorders including inflammatory bowel disease, non-alcoholic fatty liver and irritable bowel syndrome. Knowledge gained can be used as building blocks for future therapeutic strategies. The Michail lab is charged with understanding how the gut microbiome can help prevent illness and treat pediatric disease and how to manipulate the microbiome to our advantage.

Fecal Microbial Transplant

Dr. Sonia Michail is leading a program for fecal microbial transplant to treat children with recurrent clostridium difficile infection and has research studies to offer this new therapy for children with inflammatory bowel disease. View Clinical Trial.

IBD Smartphone App

Through the generous gift from the Higgins Family Foundation, Dr. Michail has developed a smartphone application for children with inflammatory bowel disease that allows children to inform us of their status in a timely manner and receive information from the managing team about their overall success in controlling their disease.

ChiLDREN Liver Center

Dr. Michail is a co-investigator in the ChiLDREN Liver Research Center at Children’s Hospital of Los Angeles, a research effort to understand and treat infant and pediatric liver disease.


Probiotics are good bacteria that can be taken by individuals for health benefit. Dr. Michail’s research effort helps us understand how those probiotics can enhance the health of children with various digestive disorders.

Research Studies

To know if stool transplant from a healthy person into an ulcerative colitis patient can help treat the disease.

Safety of Fecal Microbiota Transplantation (FMT) in children with Crohn's disease in remission.

To evaluate the efficacy of tofacitinib based on remission in pediatric participants with moderately to severely active Ulcerative Colitis (UC).
