A confirmed case of Theileria orientalis Ikeda, a protozoal organism affecting cattle, has been reported in Lawrence County. The disease infects red blood cells and displays symptoms similar to anaplasmosis but with key differences, experts say. Unlike anaplasmosis, Theileria orientalis Ikeda can also affect younger animals, including calves and pregnant heifers.
The disease is transmitted in two primary ways: through blood-contaminated equipment, such as needles or tagging tools, and through the Asian longhorned tick. Symptoms in infected animals may include anemia, jaundice, fever, lethargy, abortion, and in some cases, death.
Livestock owners are advised to contact a veterinarian immediately if their animals display any signs of the disease. The Lawrence County Extension Office is seeking community assistance in gathering information about the prevalence of the Asian longhorned tick in the area. Residents willing to participate in sampling efforts can contact the office at (870) 886-3741 for more details.
Theileria orientalis Ikeda poses significant health risks to cattle, making awareness and preventative measures essential as residents work livestock this fall.
