E-Mail During every instant of life, over a hundred trillion microbes, collectively known as the microbiome, reside on skin surfaces and course through the human body. In the human gut, vast colonies of bacteria, belonging to around 1000 different species, carry out duties ranging from the digestion of food and the management of body weight to effects on the brain and behavior, many of these still elusive to science. Recent studies in mice and humans have revealed intriguing links between the composition of gut microbiota and Autism Spectrum Disorder (ASD), a disease believed to affect one in 54 children, according to the Centers for Disease Control. Dr. Krajmalnik-Brown's lecture will propose linkages between gut bacteria and ASD, highlighting encouraging results of a microbiome-targeted, ASD open-label clinical trial.
