title: Environmental factors and their impact on the intestinal microbiota: a role for human disease?
abstract: The intestinal microbiota and its potential role in human health and disease have come into the focus of interest in recent years. An important prerequisite for the achieved advances with regard to a better characterization of its complex composition and influencing factors is the increasing availability and affordability of culture-independent methods, such as high-throughput sequencing technologies. We discuss some general aspects of the intestinal microbiota. Recent insights into its potential pathogenetic role in the metabolic syndrome and inflammatory bowel disease will also be discussed that imply an impact of smoking status and smoking cessation on intestinal microbial composition.
