New strain of Lyme disease produces different symptoms that could complicate diagnosis
Mayo researchers have discovered a new strain of Lyme disease that is raising concerns because it does not produce the bull’s-eye rash that typically alerts people to the condition.
The culprit is a new species of bacteria found in the Upper Midwest and reported in the online medical journal, the Lancet Infectious Diseases.
“It was a fortuitous discovery,” said Dr. Bobbi Pritt, director of the Clinical Parasitology Laboratory at Mayo Clinic in Rochester. “We weren’t setting out to find a new organism.”
