Tick Testing Available at UConn

Headed outdoors? Make sure you take precautions against ticks in October and November. Adult ticks are more active during this time of the year, creating a problem for both humans and animals.

These disease-carrying arachnids reside in moist areas, long grass and the leaf litter and will latch onto humans and animals alike. Although there are many different species of ticks, people generally think of one tick species in particular when worrying about illness: the deer tick. While the Deer tick is predominantly known for transmitting Lyme disease (caused by the corkscrew-shaped bacterium, Borrelia burgdorferi) it can also carry other disease causing agents such as Anaplasma phagocytophilum, Babesia microti and Borrelia miyamotoi. These are the causative agents of Granulocytic Anaplasmosis, Babesiosis and Borrelia miyamotoi respectively. A single tick has the potential to transmit one, two, or even all four of these illnesses simultaneously! Other species of ticks found in the Northeast such as the Dog tick (Dermacentor variablis), Brown Dog tick (Rhiphcephalus sanguineus) and Lonestar tick (Amblyomma americanum) can also be tested for different pathogens known to cause illness in humans and/or animals.

If you find a tick on yourself, your child, or your pet, remove it immediately but do not make any attempt to destroy it. The Connecticut Veterinary Medical Diagnostic Laboratory (CVMDL) at UConn can test the tick for all those pathogens. Ticks received at the CVMDL are first examined and identified by trained technicians using a dissection microscope. This identification process determines the species of tick, life stage, and degree of blood engorgement, all of which are factors that may impact transmission of pathogens to the person or animal (the host). Ticks may then be tested for the DNA of pathogens that are known to be transmitted by that tick species. Results are reported within 3-5 business days of receiving the sample. Next business day RUSH testing is available for an additional fee. The information obtained from testing your tick at UConn is very useful when consulting with your physician or veterinarian about further actions you may need to take.

Compared to 2016, this year, the CVMDL has seen a significant increase in the numbers of tick submissions to the laboratory. In the month of April the number of submissions increased 92% relative to the same month in 2016. The increases for other warm weather months were 104% in May, 70% in June and 60% in July. CVMDL speculates that changes in weather patterns this year may have affected changes in tick populations and with that, increased number of tick submissions to the lab.

CVMDL is the only laboratory in New England accredited by the American Association of Veterinary Laboratory Diagnosticians. The laboratory is located on the UConn-Storrs campus and provides diagnostic services, professional expertise, research and detection of newly emerging diseases, and collaborates with federal, state, and local agencies to detect and monitor diseases important to animal and human health.

How to send in ticks: Please send ticks in sealed, double zip lock bags accompanied by a small square of moist paper towel. The submission form and the “Do’s and Don’ts of tick testing” can be found on our website at http://s.uconn.edu/tickform. You can also watch a video produced by UConn Communications for the Science in Seconds series here.
