1. New Insights Into Costly Destruction Of Subsurface Petroleum
   09-29-2006 · ScienceDaily
   Scientists are reporting an advance toward understanding and possibly combating a natural process that destroys billions of dollars worth of subsurface petroleum. Called biodegradation, it occurs as bacteria and other microbes metabolize, or feed on, organic compounds present in crude oil.

4. McBride shows DNA detective work with paper-eating bacteria that 'glide'
   01-02-2007 · EurekAlert!
   A professor at the University of Wisconsin-Milwaukee has been helping the Department of Energy analyze the genome of a "paper-eating" bacterium that could have uses in producing ethanol, but also shed light on how "gliding" bacteria move. The two functions could be related.

5. Prehistoric origins of stomach ulcers uncovered
   02-07-2007 · EurekAlert!
   Scientists have discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. They compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers and found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H.pylori.

9. Assumption of function not always correct
   05-01-2007 · EurekAlert!
   A protein called RecQ takes on a totally opposite function in the bacteria Escherichia coli to the one it fulfills in yeast and in humans, indicating that people seeking to understand the role of different forms in human cells and disease need to consider both possibilities, said researchers from Baylor College of Medicine in a report in the current issue of Molecular Cell.

10. Resistance genes in our food supply
    05-23-2007 · EurekAlert!
    Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria?
