Summary

Dr. Sara Wyckoff, a wildlife veterinarian for Texas Parks and Wildlife, presents an update on several wildlife diseases affecting West Texas. She begins with Mycoplasma ovipneumoniae (M. ovi) in bighorn sheep, discussing ongoing surveillance, strain typing, and the importance of understanding strain diversity to prevent disease spread. Next, she covers infectious keratoconjunctivitis (pink eye) and nightshade toxicosis in desert bighorn sheep, describing a case where both conditions occurred simultaneously. She then provides updates on chronic wasting disease (CWD) monitoring projects, including collaring efforts and voluntary testing. The presentation also addresses Rabbit Hemorrhagic Disease Virus 2 (RHDV2), highlighting a vaccination efficacy study for the threatened Mount Davis cottontail. She briefly mentions epizootic hemorrhagic disease (EHD) and bluetongue, noting that mule deer and pronghorn are more resistant than whitetail deer. The main focus is on New World screwworm, a parasitic fly that infests living tissue of warm-blooded animals. She details the current outbreak in Texas, with 45 cases, and emphasizes the importance of early detection and reporting. She outlines the response efforts, including sterile fly releases and surveillance, and provides contact information for reporting suspected cases.

Critical Evaluation

Value of the Information & Strength of the Argument

The presentation provides valuable, up-to-date information on wildlife disease management in Texas, based on the speaker’s professional experience and departmental data. The argumentation is solid, as she supports her points with specific examples, such as the dual diagnosis of pink eye and nightshade toxicosis, and the ongoing research on RHDV2 vaccination. She effectively communicates the importance of surveillance and collaboration in disease control. However, the talk is primarily an expert opinion and lacks detailed scientific citations, which limits its depth for a research audience.
