With deer hunting under way in Missouri, the Missouri Department of Conservation (MDC) and A.T. Still University in Kirksville are asking deer hunters to save ticks they find on harvested deer and mail them to the University. The ticks will be used for a scientific research study to help better understand the statewide distribution of tick species and the human pathogens they carry. Missouri! Send us ticks!
“During this time of year, we are asking the many Missouri deer hunters around the state to send us ticks they find on their harvested animals,” said MDC Ecological Health Unit Science Supervisor Matt Combes. “The University needs more samples – especially of deer ticks, also called blacklegged ticks, which are commonly found on deer this time of year.”
Ticks are large mites that drink the blood of humans and other mammals. Ticks can also carry and spread pathogens that cause illnesses in people. Missouri is home to three common species of ticks that bite humans: lone star tick, American dog tick, and deer tick (blacklegged tick). Deer ticks are the primary transmitters of a bacterial infection called Lyme disease. Adult ticks are about a quarter-inch long and grow to nearly double that when engorged with blood. Learn more about ticks from the MDC online Field Guide at nature.mdc.mo.gov/discover-nature/field-guide/ticks.
MDC and A.T. Still University are partnering on a two-year research study to determine the presence of tick species throughout Missouri as well as the pathogens they may harbor. The study began in April and concludes in September 2022. During that time, MDC and the University are asking Missourians mail ticks to A.T. Still University to be identified by species and life stage and tested for four species of bacterial pathogens.
To help with the research efforts, people are asked to place live ticks in a plastic zip-top bag with a piece of damp paper towel or moist cotton ball, then fold the bag and place it inside another plastic zip-top bag with a completed sample-submission form. The sample-submission form is available for printing from the University website at www.atsu.edu/missouri-ticks-and-tick-borne-pathogen-surveillance-research. Send us ticks!
People are then asked to place the bag and completed sample-submission form in an envelope and mail it to: A.T. Still University, ATTENTION: Deb Hudman — Dept. of Microbiology & Immunology, 800 W. Jefferson St., Kirksville MO 63501.
University Senior Research Associate Deb Hudman noted the research is not intended to provide clinical diagnosis of any illness someone may have, and study information should not be interpreted as a substitute for medical testing or consultation with a physician.
“The resulting research data will be used to determine at the county level what tick species and bacterial pathogens are present for the state of Missouri. This much-needed data will be shared with the Centers for Disease Control and Prevention (CDC) and the Missouri Department of Health and Senior Services,” said Hudman. “This data will also help guide outreach and education efforts about ticks in Missouri to help increase knowledge of tick-borne illnesses and precautions people should take when working or recreating in the outdoors.”
She added that distribution maps are provided and updated weekly on the A.T. Still University website at www.atsu.edu/missouri-ticks-and-tick-borne-pathogen-surveillance-research so people can actively follow the progress of the study over the next two years.
Combes added there is a pressing need to increase tick surveillance in Missouri, develop statewide distribution maps of tick species and tick-borne pathogens, and educate the public on reducing their risk of contracting a tick-borne illness based on that data. In addition, this research study could also help determine previously unknown or invasive tick species that are present in Missouri.
“There are tick-borne human pathogens in the state of Missouri and yet there is no comprehensive map of where tick species occur, or of the human pathogens those ticks are carrying,” Combes said. “According to the CDC, Missouri is considered a gap state for knowledge of tick-borne diseases. Many people — in Missouri and nationwide — lack a good understanding of tick-borne illnesses common to their area.” So, Missouri! Send us ticks!
