Tick-borne borreliosis, or Lyme disease, is the most common disease transmitted through tick bites. Curiously, the animals themselves are not infected with Borrelia, although the beetles actively feed on large hoofed animals such as white-tailed deer. Scientists speculated that something in the deer’s body was killing the bacteria, preventing them from multiplying, but until now no one has conducted experiments to find out how.
Microbiologists decided to fill this gap and obtained blood serum from white-tailed deer. They grew borreliosis pathogens in the lab and exposed them to serum. This killed all the bacteria.
Researchers now need to learn exactly how the serum affects the Lyme disease-causing agent.
