Haemaphysalis longicornis (Asian longhorned tick) identified in TN
The invasive Asian longhorned tick (Haemaphysalis longicornis) has been identified from dogs, cattle, and deer (1) in 8 counties in TN. Haemaphysalis longicornis is a known vector of significant human and animal pathogens in its home range, but its significance as a vector of disease in the United States requires further investigation. The tick feeds on a wide variety of hosts including humans and many other domestic and wild animals and can expand its population rapidly and establish an infestation parthenogenetically (without male fertilization). Ticks were noted on necropsy by UTCVM pathologists or submitted for identification by local veterinarians and identified by the UTCVM Diagnostic Parasitology Laboratory, Dr. Rebecca Trout-Fryxell (UTIA medical and veterinary entomologist), and confirmed by the NVSL. Collaborative monitoring efforts by UTIA, UTCVM, TWRA, and the USDA are ongoing to evaluate the extent of the tick’s range in Tennessee. Ticks may be submitted to the UTCVM Diagnostic Parasitology Laboratory for parasite external identification.
Please visit the Tennessee Department of Agriculture for further details on Haemaphysalis longicornis.

Toxoplasma gondii MAT testing

We are excited to announce that the MAT (Modified Agglutination Test) for the detection of anti-Toxoplasma gondii IgG antibodies in serum samples has returned to the UTCVM Diagnostic Parasitology Laboratory. We are able to offer this test through collaboration with Dr. Chunlei Su’s laboratory in the UT Microbiology Department.  Download the Toxoplasma TgMAT handout for more information.
