Scientists reveal quirky feature of Lyme disease bacteria
Date:3/21/2013

uperoxides so that the pathogens can continue to grow.

The discoveries open new possibilities for therapies, Culotta said. "The only therapy for Lyme Disease right now are antibiotics like penicillin, which are effective if the disease is detected early enough. It works by attacking the bacteria's cell walls. But certain forms of Borrelia, such as the L-form, can be resistant because they are deficient in cell walls."

"So we'd like to find targets inside pathogenic cell that could thwart their growth," she continued. "The best targets are enzymes that the pathogens have, but people do not, so they would kill the pathogens but not harm people." Borrelia's distinctive manganese-containing enzymes such as superoxide dismutase may have such attributes.

In search of new avenues of attack, the groups are planning to expand their collaborative efforts by mapping out all the metal-binding proteins that Borellia uses and investigating biochemical mechanisms that the bacteria use to acquire manganese and directs it into essential enzymes. Knowing details of how that happens offers ways to disrupt the process and deter Lyme Disease.
