We’re seeing some Tick Fever (Anaplasmosis) cases recently, and wanted to share this information to help keep our horse community aware, informed, and safe.

Tick Fever (Equine Anaplasmosis): What Horse Owners Need to Know

This disease is spread by Ixodes ticks (deer ticks) and often shows up 1–2 weeks after a tick bite.

Common signs include:
• High fever (often over 103°F)
• Lethargy, depression, and being “off feed”
• Limb swelling (edema) or swelling along the belly or sheath
• Yellow-tinged gums or eyes (jaundice)
• Small purple/red spots on the gums or eyes (petechiae)
• Stiffness, incoordination, or reluctance to move

Age matters:
• Younger horses may show only fever and mild depression
• Adult and senior horses tend to develop more severe, classic signs

How it is commonly diagnosed:
• Bloodwork and stall-side inflammatory markers (CBC, chemistry, SAA)
• PCR testing

What you can do (prevention is ideal):
• Check horses daily for ticks
• Remove ticks promptly
• Use tick control strategies on horses and property

📞 If your horse has a fever or sudden swelling, call us promptly 530-955-6556.

Early treatment makes a big difference and prognosis is excellent when caught early.

Dr. Corey is currently attending an advanced ultrasound imaging workshop in Arizona for a couple days!

As many of you know, ultrasound imaging is one of Dr. Corey's passions. He is constantly focused on providing more comprehensive evaluations, targeted treatments, and rehabilitation plans, from the bottom to the top of the horse, and everywhere in between!

Dr. Corey is using ultrasound here to evaluate the extent of a wound on the hock of this horse. We can use metallic probes to see exactly where a penetrating wound went on ultrasound and X-ray.
