Raising babies and their microbes. Pregnancy : eating for two? : try eating for trillions ; Birth : welcome to the world of microbes ; Breast milk : liquid gold ; Solid foods : a growing diet for microbes ; Antibiotics : carpet bombing the microbiota ; Pets : a microbe's best friend ; Lifestyle : microbe deficit disorder

Collateral damage. Obesity : the world is getting heavier ; Diabetes : microbes have a sweet tooth ; Intestinal diseases : fire in the gut! ; Asthma and allergies : microbes keep us breathing easy ; Gut feelings : microbiota and the brain ; Vaccines work! ; Bugs as drugs.
