It’s Arachnid World Week day #3! Here’s a behind the scenes look at Ticks: Dangerous Hitchhikers with author Sandra Markle:

Dr. Tom Mather has discovered that, somehow, 70 percent of all guinea pigs bitten by ticks carrying disease organisms don’t get sick. So he’s now studying what happens at the cellular level inside guinea pigs when they’re bitten by ticks that could be protecting them. His goal is to figure this out and then devise a way to develop a vaccine that will protect people from tick-borne diseases. Dig into this book to find out how the tick’s life cycle is part of the reason these arachnids spread diseases.
