Respiration of Microbiota-Derived 1,2-propanediol Drives Salmonella Expansion during Colitis

Intestinal inflammation caused by Salmonella enterica serovar Typhimurium increases the availability of electron acceptors that fuel a respiratory growth of the pathogen in the intestinal lumen. Here we show that one of the carbon sources driving this respiratory expansion in the...

Intestinal inflammation caused by Salmonella enterica serovar Typhimurium increases the availability of electron acceptors that fuel a respiratory growth of the pathogen in the intestinal lumen. Here we show that one of the carbon sources driving this respiratory expansion in the mouse model is 1,2-propanediol, a microbial fermentation product. 1,2-propanediol utilization required intestinal inflammation induced by virulence factors of the pathogen. S. Typhimurium used both aerobic and anaerobic respiration to consume 1,2-propanediol and expand in the murine large intestine. 1,2-propanediol-utilization did not confer a benefit in germ-free mice, but the pdu genes conferred a fitness advantage upon S. Typhimurium in mice mono-associated with Bacteroides fragilis or Bacteroides thetaiotaomicron. Collectively, our data suggest that intestinal inflammation enables S. Typhimurium to sidestep nutritional competition by respiring a microbiota-derived fermentation product. 2018-04-25T06:55:31Z 2018-04-25T06:55:31Z 2017-01-01 Journal 15537374 15537366 2-s2.0-85011005490 10.1371/journal.ppat.1006129 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85011005490&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/46480 |
