Description:
Undernourished children exhibit impaired development of their gut microbiota. Transplanting microbiota from 6- and 18-month-old healthy or undernourished Malawian donors into young germ-free mice that were fed a Malawian diet revealed that immature microbiota from undernourished infants and children transmit impaired growth phenotypes. The representation of several age-discriminatory taxa in recipient animals correlated with lean body mass gain; liver, muscle, and brain metabolism; and bone morphology. Mice were cohoused shortly after receiving microbiota from healthy or severely stunted and underweight infants; age- and growth-discriminatory taxa from the microbiota of the former were able to invade that of the latter, which prevented growth impairments in recipient animals. Adding two invasive species, Ruminococcus gnavus and Clostridium symbiosum, to the microbiota from undernourished donors also ameliorated growth and metabolic abnormalities in recipient animals. These results provide evidence that microbiota immaturity is causally related to undernutrition and reveal potential therapeutic targets and agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4787260/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4787260/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blanton, Laura V -- Charbonneau, Mark R -- Salih, Tarek -- Barratt, Michael J -- Venkatesh, Siddarth -- Ilkaveya, Olga -- Subramanian, Sathish -- Manary, Mark J -- Trehan, Indi -- Jorgensen, Josh M -- Fan, Yue-Mei -- Henrissat, Bernard -- Leyn, Semen A -- Rodionov, Dmitry A -- Osterman, Andrei L -- Maleta, Kenneth M -- Newgard, Christopher B -- Ashorn, Per -- Dewey, Kathryn G -- Gordon, Jeffrey I -- R37 DK030292/DK/NIDDK NIH HHS/ -- T32 AI007172/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 19;351(6275). pii: aad3311. doi: 10.1126/science.aad3311.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genome Sciences and Systems Biology and Center for Gut Microbiome and Nutrition Research, Washington University School of Medicine, St. Louis, MO 63108, USA. ; Sarah W.
