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.

Tick Testing at UConn

Summer in Connecticut is the perfect time to get outside and enjoy the sunshine. There are beautiful trails to hike, parks to visit with your children or dogs, and there is the simple joy of lying in the lush, green grass. Of course, the warm weather also comes with the New England outdoor enthusiast’s nemesis – the tick. These disease-carrying arachnids enjoy moist areas with long grass and will latch onto humans and animals alike. Although there are many different species of tick, 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 spirochetal bacterium, Borrelia burgdorferi) it can also carry other disease causing agents such as Anaplasma phagocytophilum and Babesia microti. These are the causative agents of Human Granulocytic Anaplasmosis and Babesiosis respectively. A single tick has the potential to transmit one, two, or even all three of these illnesses simultaneously!

If you find a tick on yourself, your child, or your pet, remove it immediately! The Connecticut Veterinary Medical Diagnostic Laboratory (CVMDL) can test the tick for pathogens. Ticks received at the CVMDL are first observed under a microscope by trained technicians to determine 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. Ticks may then be tested for the DNA of pathogens that are common to that tick species. Results are reported within 3-5 business days of receiving the sample, and next day testing is available for an additional fee.

Controlling Ticks

The Centers for Disease Control and Prevention (CDC) recommends creating a tick-safe zone. Ticks feed on blood of animals including humans. Tactics to reduce the attractiveness of animals traveling into your yard will keep the number of ticks dropping off of them reduced. Do not feed the birds as chipmunks, squirrels and many other animals visit to eat fallen seeds. Remove leaf litter as a hiding place for small animals and ticks. Clear tall grass and brush from edges of turf and around home. Keep lawn mowed. Keep any wood piles dry and neatly stacked to discourage rodents from using it as a home. Do not place patio or play areas near wooded areas where animals and ticks will be living. Use fencing to keep out deer and larger animals from the yard. Create a 3-foot wide barrier of gravel or wood chips between lawns and woods to stop ticks from entering the lawn. Ticks do not like to cross hot, dry expanses.

 

Chemical control includes the active ingredient bifenthrin or carbaryl or permethrin or pyrethrin. These are best applied when the ticks are in their small nymphal stage during the month of May and early June. See the CT Tick Management Handbook written by the CT Agricultural Experiment Station for much more detailed information.

Tick Testing for Lyme Disease and Other Pathogens

Ticks can transmit Lyme disease and other diseases to humans and animals

◦  CVMDL can test ticks for the infectious agents causing Lyme and other diseases using PCR technology

◦  Results of tick testing assists health care providers in offering the most appropriate treatment or avoid unnecessary treatment

All ticks submitted to CVMDL are identified morphologically by species, stage, and degree of engorgement prior to testing. Results are reported within 3-5 business days of receiving the sample.
