Theileriosis, Anaplasmosis & Herd Health - Cattlemen & Veterinarians

In this episode of Cattlemen and Veterinarians: A Partnership in Bovine Health, hosts Kaid Panek and Dr. Shania Peterman, DVM, welcome Dr. Bob Gentry, DVM, Technical Services Veterinarian with MedGene, for an in-depth discussion on two emerging and economically significant cattle diseases: bovine theileriosis and anaplasmosis. As tick populations expand across the United States, understanding these diseases has become increasingly important for cattle producers looking to protect herd health and minimize production losses. Dr. Gentry explains the differences between anaplasmosis, a bacterial disease that has long been established throughout much of the country, and bovine theileriosis, an emerging disease caused by the Theileria orientalis Ikeda strain and spread primarily by the invasive Asian longhorned tick. Although the diseases share many clinical signs—including anemia, jaundice, lethargy, and reduced performance—accurate diagnosis through laboratory testing is essential because treatment and management strategies differ significantly. The conversation explores where these diseases are currently found, how they continue to spread, and the role ticks, biting insects, contaminated needles, and animal movement play in disease transmission. Dr. Gentry also discusses available diagnostic tools, treatment options for anaplasmosis, why no approved treatment currently exists for bovine theileriosis, and the exciting progress being made toward new vaccines designed to help producers better protect their herds. Throughout the episode, Kaid and Dr. Peterman emphasize the importance of proactive herd health management, biosecurity, and working closely with veterinarians to develop disease prevention strategies. Practical recommendations—including tick control, proper vaccination and injection practices, and monitoring cattle for early clinical signs—provide listeners with actionable steps they can implement on their own operations. Whether you're located in an area where these diseases are already established or simply want to stay ahead of emerging health challenges, this episode delivers valuable insights from one of the industry's leading veterinary experts. Tune in to learn how education, early detection, and sound management practices can help safeguard the health, productivity, and profitability of your cattle operation while preparing for the future of bovine disease prevention.
