Almost anyone spending time outdoors knows about the link between ticks and Lyme disease. But there may be far more lurking in tick bites than previously thought – a cocktail of bacteria and viruses that may uniquely affect each bite victim and inhibit the remedies meant to cure tick-borne diseases. “Climate change is expanding tick ranges, and we’re spending more time in tick habitats all the time,” said Catherine Hill, a Purdue professor of entomology and vector biology. “As we come into more contact with ticks, we increase the likelihood of being bitten and contracting a tick-borne disease. We’re finding that it’s not just one microbe these ticks could pass on to us. It’s like a little microbe party in there, and we need to figure out how their interplay can affect human health.”
