Study Shows Equine Kidneys Have Unexplained Anomaly

A recent study investigating equine kidneys has found a curious anomaly between the left and right organs that they can’t explain. The study, led by Drs. Francesca Freccero, Marina Petrucelli, Mario Cipone, Irene Nocera and Micaela Sgorbini, used pulse-wave Doppler ultrasound on 33 healthy horses and donkeys to try to better understand their kidney function.

Best Practices For Equine Antibiotic Use

Horse owners and caretakers are again being warned about the overuse of prescribed antibiotics as the threat of antimicrobial resistance (AMR) escalates worldwide. Antimicrobials are used in both equine and human medicine; they are integral to the treatment of infections. However, excessive and inappropriate use of antimicrobials has led to the emergence of antibiotic resistant […]

Multiple Drug Resistance In Horses Has Reached ‘Concerning’ Levels

Over 3,000 equine antibiotic susceptibility test results reviewed by the University of Liverpool show that multiple drug resistance (MDR) has reached a concerning level. Dr. Cajsa Isgren presented her findings at the British Equine Veterinary Association conference. Using samples from six large equine diagnostic laboratories, the researchers found resistance to at least one class of […]

A Scientific Crystal Ball: The Future Of Dewormer Resistance

Drs. Martin Nielsen, Christian Sauermann and Dave Leathwick have used computer modeling to simulate small strongyle resistance to ivermectin over the next 40 years. Small strongyles are very common and infect almost every horse that grazes on pasture. The worms can trigger a disease called larval cyathostominosis, which occurs when encysted small strongyle larva emerge […]

Sable Island’s Feral Horses Perishing From Starvation And Worms

Horses have been found on Sable Island, off the coast of Nova Scotia, since the 18th century. Though hardy, the feral horses are dying; a team of researchers has been investigating the cause of the recent deaths. Dr. Emily Jenkins, one of the researchers, has discovered that the horses are perishing from starvation as well […]

Resistance To Common Dewormer May Endanger Foals

Large roundworms, a common parasite in foals, are becoming resistant to pyrantel, a type of dewormer, a Swedish study shows. Pyrantel is used to treat roundworm infestations, which can negatively effect and even kill young horses.┬áMature worms live in the small intestine; a heavy worm load can cause foals not to thrive and may cause […]

Human Health Innovations Can Be Used To Keep Horses Sound

Tendon injuries in horses can be difficult to rehabilitate, and should include monitoring of pain, heavy and slow loading, and progressive resistance. Equine veterinarians are turning to human medicine to offer horses additional tendon-healing strategies, which Dr. Seth O’Neill, PhD, MSc, PGCE, HE, MCSP, MMACP, of the University of Leicester’s College of Life Sciences, discussed […]
