Effects of Crude Oil-Dispersant Mixtures on the Human Microbiome
NCTR scientists showed that high concentrations of a mixture of crude oil and chemical dispersant can adversely affect intestinal microbiota in in vitro human fecal slurries; but crude oil or dispersants alone have no effect.  In this study, the effects of Deepwater Horizon crude oil and the dispersant, Corexit 9500, on bacterial communities and bacterial numbers in the cultures were analyzed using a combination of molecular techniques.  It is important to note that the low-level residue concentrations of these materials that could potentially contaminate seafood products are well below the higher concentrations that were shown to affect human intestinal microbiota in this study.  The results of this study have been published in mBio (http://dx.doi.org/10.1128/mBio.00376-12).
