About the Parasitology Section

​The parasitology section of the CSU Veterinary Diagnostic Laboratory provides full-service, diagnostic support for the detection of parasitic infections in domestic and wild animals. This service is provided in a timely and cost-efficient manner. Accurate detection of parasites benefits animals by helping to improve animal health. The section also serves to safeguard public health through the rapid and reliable detection of zoonotic parasites.

The section is overseen by Dr. Lora Ballweber, who has more than 18 years of experience in veterinary parasitology.
