Protecting Cattle Health: University Products’ Vital Role in Fighting Bovine Anaplasmosis with Vaccines Amid South Dakota’s Outbreak

BATON ROUGE, La. , Jan. 17, 2024 /PRNewswire/ — University Products LLC, a pioneer in animal vaccine solutions, is helping to tackle the escalating threat of bovine anaplasmosis in South Dakota and beyond during recent unseasonable weather. The changing climate conditions have extended the lifespan of disease-spreading insects like ticks and biting flies, posing a significant risk to cattle herds. And a recent discovery of anaplasmosis near Woonsocket, South Dakota, highlights the urgent need to protect herds now from this costly endemic infection.

Unpredictable Weather, Unforeseen Challenges

Across the U.S., ranchers face a variety of unprecedented challenges due to severe vector shifts. But among the diseases posing the most serious threat to herds is bovine anaplasmosis, caused by the bacteria, Anaplasma marginale. The bacteria attack red blood cells, resulting in early signs such as fever, anemia, weakness, and loss of appetite.

As the disease progresses, it can lead to worse symptoms like jaundice, incoordination, and even death. Anaplasmosis can also increase the risk of abortions, while infecting whole herds – resulting in catastrophic costs to ranchers and the cattle industry.

Gene Luther, a researcher at University Products, emphasized the importance of intervention as key to winning the fight:

“Anaplasmosis devastates cattle herds quickly and quietly. Often, the disease spreads rapidly before ranchers are even aware. It’s sometimes challenging to diagnose, especially with other concurrent cattle diseases like Babesia, and Theileria, which share similar symptoms. So ranchers must recognize anaplasmosis signs immediately and involve their veterinarians to stay ahead of this.”

Combatting the Spread of Anaplasmosis: Pharmaceutical Stewardship

“Transmission primarily occurs through ticks, biting flies, and contaminated equipment like shared vaccine or antibiotic needles,” explained researchers. “Producers have to implement effective preventive strategies early, with proper management and vaccination, to reduce the risk of anaplasmosis. Our vaccine is a well-tested tool.”

With limited treatment options available for anaplasmosis, pharmaceutical use remains another key issue – especially with recent FDA crackdowns on the use of animal antibiotics. Researchers emphasizes the need for responsible antimicrobial use, ensuring the long-term effectiveness of these products:

“Veterinarians tell ranchers this often, but it’s absolutely worth repeating. You cannot rely on antibiotics over and over again to protect herds from these bacterial diseases. It just leads to more resistant strains down the road. And while judicious use of antimicrobials to combat active anaplasmosis outbreaks makes sense in the short term, prevention is much more cost effective overall.”

The major message to cattle producers is clear: “Diligence and vigilance are our best defenses against anaplasmosis. By working closely with your vets, implementing biosecurity measures like fly and tick prevention programs, and vaccinating bulls as a preventative, ranchers can better protect from this persistent threat.”

University Products produces the only vaccine (for experimental use) against anaplasmosis.
