Mouth Bacteria Can Change Its Diet, Supercomputers Reveal

RATE THIS! +28
Posted in Science on 13th Aug, 2014 02:19 AM by AlexMuller

Bacteria inside your mouth drastically change how they act when you're diseased, according to research at the Texas Advanced Computing Center. Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, diabetes, and Crohn's disease.

 
Marvin Whiteley, professor of molecular biosciences and director of the Center for Infectious Disease at The University of Texas at Austin, led the study published in April 2014 in the journal mBio. "What we were trying to figure out," said Whiteley, "is how do these bacteria act when you're healthy, and how do they act when they're in a diseased state. The really big finding is that they do act very differently." Bacteria share nutrients, and one species will even feed on another as they constantly interact. "The thing that we found in this paper," said Whiteley, "is that this sharing, and how they interact with each other changes quite drastically in disease than it does in health."
 
UT Austin researchers used shotgun metagenomic sequencing, a non-targeted way to study the all the genetic material of the bacterial communities. Whiteley and colleagues analyzed the RNA collected with the Lonestar and Stampede supercomputers at TACC. They were awarded computing allocations through the University of Texas System Research Cyberinfrastructure initiative. The research was funded by grants from the National Institutes of Health, administered by the National Institute of Dental and Craniofacial Research.

Interesting work that can help understand how microbes in human body behave - this is important as number of microbes outnumber the host cell. As someone put it- this is their world and we just live in it..... Reply
