Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron within a range that is healthy for them. Now Theresa D. Ho, PhD, and Craig D. Ellermeier, PhD shed new light on how the pathogen, Clostridium difficile, which is the most common cause of hospital-acquired infectious diarrhea, regulates iron. The research is published online ahead of print July 6 in the Journal of Bacteriology, a publication of the American Society for Microbiology.
