Rare Lyme Variant Emerges in New York, First Local Case of B.‑mayonii
Researchers confirm the first locally acquired case of Borrelia mayonii, a rarer Lyme-causing bacterium, in New York after a Central New York resident developed symptoms and was treated successfully with doxycycline; ticks collected on the patient’s property tested positive for B. mayonii, suggesting local tick transmission and possibly an established animal reservoir, signaling a need for ongoing surveillance as tick populations expand with climate change.
