In what ways does the microbiome affect exposure to toxic chemicals? Nature 449, 804810 (2007). Germ-free animals, both wild-type and genetically engineered, that have been colonized at various stages of their lives with simplified microbial communities composed of a few sequenced members, or with more complex consortia, should be useful because they provide the opportunity to constrain several variables, including host genotype, microbial diversity and environmental factors such as diet. There are also links to other parts of the work including: Objectives, microbial profiling, data analysis, and more. NIEHS provides many opportunities for funding to individual researchers, organizations, and businesses. J. Nutr. Tap here to review the details. Germ-free animals have a smaller heart as a proportion of body weight than their colonized counterparts54. 2015. The rationale behind FMT is simple: antibiotics and other factors disrupt the normal balance of colonic flora and reduce colonization resistance, allowing pathogenic C. difficile strains to grow, leading to the typical clinical presentations of diarrhea and pseudomembranous colitis; by reintroducing normal flora via donor feces, the imbalance can be corrected, the cycle interrupted, and normal bowel function re-established. Some microbes alter environmental substances in ways that make them more toxic, while others act as a buffer and make environmental substances less harmful. 0000020987 00000 n TETRA: a web-service and stand-alone program for the analysis and comparison of tetranucleotide usage patterns in DNA sequences.
