How many times have you been told by a dr not to worry about a tick bite because only deer ticks pass Lyme? Well now according to this research you also need to be worried about Lone Star ticks. And to top it off, Lone Star ticks were believed to live in Southern regions now are being found all the way up Wisconsin. So as the ticks spread across the states so does disease. Please read the following two articles.
UNF Researchers Make Big Discovery About Lyme Disease
By MELISSA ROSS
“Dr. Kerry Clark, University of North Florida associate professor of public health, and his colleagues have found two species of Lyme disease bacteria previously unknown to infect humans in patients.
“This study’s findings suggest that multiple Borrelia species may be causing Lyme disease in the Southeast, another tick species may also be transmitting it in the Southeast and that it may be much more common here than was previously thought,” says Clark. “Additional evidence presented suggests that some people may develop chronic infections, and the current antibody testing approach for Lyme disease may not identify the infections.”
The belief that only black-legged “deer ticks” can transmit Lyme disease has been widely publicized for decades. Lyme disease risk has been calculated largely based upon the prevalence and infection rate of these “deer ticks. Clark’s findings, together with past studies implicating lone star ticks associated with Lyme disease, suggest otherwise.
These two Lyme disease species, Borrelia americana and Borrelia andersonii, were found in symptomatic patients living in the Southeastern United States. The commonly found lone star tick, formerly believed by many to be incapable of transmitting Lyme disease, was implicated in some of these cases.”
Lone star tick showing up in Wisconsin
“MADISON — An aggressive tick that can cause a disease marked by fever, fatigue and possibly an allergy to meat is showing up this year in Wisconsin like never before, a UW-Madison entomologist said Monday.
One human case of the disease has been reported, in northwest Wisconsin’s Barron County, health officials said. It’s a type of ehrlichiosis that is relatively new to the state.
A dozen of the ticks, known as lone star ticks, have been reported this year despite no formal effort to find them, UW-Madison entomology professor Susan Paskewitz said.
“It says to me there actually must be thousands and thousands of them out there,” Paskewitz said. “I’m really suspicious now that we may have established populations that are capable of making it through some of our winters.”
The Barron County resident sickened in May is Wisconsin’s third confirmed case of a type of ehrlichiosis associated with lone star ticks, said Diep Hoang Johnson, vector-borne epidemiologist with the state Department of Health Services.”
