Laboratory of Vector-Borne Parasitic Infections

Laboratory research is focused on surveillance, natural history, transmission dynamics, disease processes, and novel treatment approaches of arthropod-borne protozoal agents including Hepatozoon americanum, Leishmania spp., and Trypanosoma cruzi in domestic animals in Oklahoma. Additionally, the lab is actively engaged in work characterizing filarid infections in dogs within the state.

What We Do

We are currently collecting kissing bugs from Oklahoma and surrounding areas. We test voluntarily submitted kissing bugs by PCR to detect DNA of Trypanosoma cruzi, the causative parasite of Chagas disease. Upon request, PCR is available to identify the animal species of the kissing bug's recent blood-meal.
