Osteochondrosis: Oral Hyaluronic Acid Study in Spain

An oral hyaluronan product did not produce any improvement in clinical or biochemical parameters in horses diagnosed with osteochondrosis in a new study, researchers from the Universidad Autonoma de Barcelona in Spain, recently reported. The study authors concluded that the evaluated product likely resulted in no detectable effect due to the small nu...

Old Horse Colicking? Consider Surgery a Viable Option

Geriatric horses have lower survival rates than younger horses following exploratory colic surgery, but there's no significant difference in long term survival rates between age groups, report Florida equine veterinarians in a new study. Most horses discharged post-surgically were still alive one year later, regardless of their age.

Late Term Abortion in Mares Reviewed for World Equine Veterinarians

Failure to conceive and early embryonic death both negatively impact the equine breeding industry; however, late-term abortions also occur and should not be ignored, said Michelle M. LeBlanc, DMV, Dipl. ACT, from Rood & Riddle Equine Hospital in Lexington, Ky., during the 11th Congress of the World Equine Veterinary Association, which was held Sept. 2...

Equine Recurrent Uveitis Biomarker Research a Real Eye Opener

Equine recurrent uveitis (ERU) is the most common cause of blindness in horses and is believed to affect approximately 10% of the equine population. The exact cause of ERU remains unclear, although researchers have shown that recurrent bouts of inflammation involving activated T-cells (cells largely responsible for cell-mediated immunity) lead to ...

Osteoarthritis: Turmeric Spice Might Provide Natural Remedy

Curcumin, an extract of the spice turmeric, is a natural product with potent anti-inflammatory properties that also exerts beneficial effects on cartilage metabolism. Scientists believe curcumin inhibits degradative enzymes such as metalloproteinases and cyclooxygenase-2 (COX-2) and reduces cartilage cell apoptosis (programmed cell death).

Study: Throat Anatomy Differs in DDSP Horses

Horses with persistent dorsal displacement of the soft palate (DDSP), an important performance-limiting abnormality of the upper respiratory tract, have a different anatomic location of the larynx than horses with only intermittent DDSP, report Cornell University researchers.

DDSP affects approximately 10% to 20% of racehorses and is diagnosed by ...

Researchers Describe New Equine Respiratory Condition

The bacterium Stenotrophomonas maltophilia can be associated with chronic lower airway disease in horses, reports a group of Danish researchers.

S. maltophilia is a Gram-negative bacterium that is causing disease more often in humans, particularly among the immunocompromised population, but it is only rarely reported as cau...

Compost Horse Manure Appropriately to Reduce Disease Spread

Horse manure needs to be 'cooked' for a specific length of time and at high enough temperatures to result in sufficient reductions in viability of roundworm (Parascaris equorum) eggs and Rhodococcus equi populations, report French researchers.

Composting, a popular method of managing horse manure generated on both small and large...

Study: Single EHV-1 Mutation Can Cause Lethal Neurologic Disease

A single mutation in the genome of equine herpesvirus-1 (EHV-1) was "necessary and sufficient" to cause neurologic disease in horses in a new study, reported Cornell University researchers.

All strains of EHV-1 can cause respiratory disease and abortion, but only a subset of EHV-1 strains can cause neurologic disease said Nikolaus Osterrieder, DVM...

EHV-1 Neurologic Disease a Challenge for Researchers

Despite the remarkable advances in understanding neurologic disease in horses, including the identification of the single genetic mutation that gives rise to the neuropathogenic form of equine herpesvirus type-1 (EHV-1), virologists continue to experience frustrations when it comes to studying EHV-1 in the experimental setting.
