Quality routine FECR testing is recommended in horses - A valuable reminder of the danger of importing anthelmintic resistance is given in a recent report. A case of macrocyclic lactone (ML) resistance in a group of Thoroughbred yearlings imported from Ireland to the United States is described by Martin K Nielsen, who is the Schlaikjer Professor of Equine Infectious Disease at the University of Kentucky’s Gluck Equine Research Center, and colleagues.

Persistent and large amounts of rainfall can create challenges for equine care and have negative effects on your horse’s overall health.

The Spring 2021 edition of Western College of Veterinary Medicine's Horse Health Lines is hot off the press and available for digital download. Take an inside look into the latest the scientific studies at the University of Saskatchewan's veterinary college, such as the link between caterpillars and cardiac disease in horses, and new treatment options for equine diseases and ailments.

Equine recurrent uveitis (ERU), also known as moon blindness, is the most common cause of blindness in horses worldwide. It affects 2 to 25 percent of horses globally, with 56 percent of affected horses eventually becoming blind. More than 60 percent of affected horses are unable to return to previous levels of work. ERU is most often characterized by repeated episodes of inflammation of the uveal tract of the eye (the middle layer), involving one or both eyes. A subclinical manifestation, known as insidious uveitis, does not present as outwardly painful episodes, and instead is consistent low grade inflammation (not episodic) that causes cumulative damage to the eye. Cumulative damage caused by ERU can lead to cataracts, glaucoma, and eventually blindness. Although not all horses that experience a single episode of uveitis will develop ERU, they are at risk for disease.
