A Tick that Feeds on Birds May Increase the Range of Lyme Disease


Excerpt: "If you have lived in the northeastern United States any time in the last 25 years or so, you have almost certainly heard of Lyme disease. You may have scrutinized odd-looking insect bites, wondering if they are developing the disease’s tell-tale “bulls-eye” rash. And you may have become skilled at distinguishing blacklegged ticks (Ixodes scapularis), which can transmit the pathogen, from American dog ticks (Dermacentor variabilis), which cannot.

But, blacklegged ticks aren’t the only tick species that plays a role in the Lyme disease story. Researchers at Old Dominion University in Virginia are focusing on another tick, Ixodes affinis, that can also serve as a vector for Lyme disease. But don’t look for this tick on your pant legs; I. affinis doesn’t bite humans."

Migratory Songbirds Transport New Ticks & Pathogens Across the Gulf


Excerpt: "An invasion of 19 million ticks. It might sound like the plot of a horror movie, but it’s real, and it happens every spring as migratory songbirds transport ticks — and the pathogens they carry — into the United States.

As covered previously on Cool Green Science, researchers from The Smithsonian Migratory Bird Center (SMBC) and Texas A&M University are trying to figure out just how many ticks and tick-borne pathogens neotropical songbirds are transporting from Central and South America during their annual migration.

And now they have an answer. Their results, recently published in Applied and Environmental Microbiology, reveal that neotropical songbirds are transporting an estimate of more than 19 million non-native ticks species into the country each year."
