Equine Amnionitis and Foetal Loss (EAFL) was first described in 2004 following an outbreak of abortions in mares that had an unusual and consistent pattern of clinical and pathological signs. Examination of reports for all equine abortion cases that involved submission of diagnostic material to the Scone Veterinary Diagnostic Laboratory between March and October 2004 indicated that EAFL was the most common identified cause, responsible for 28 (37%) of 76 cases...
ABSTRACT We evaluated the efficacy and residual load of an antiparasitic oral in gel (doraQuest l.a.® ) based on doramectina composition is 1.75% (w/w) in riding horses, for the control of gastrointestinal nematodiasis, for a period of 70 days post- treatment. The study was conducted at the Army Equitation School of La Molina, Lima, Peru, between the months of January to March 2007. Twenty horses were selected, whose ages were an...

Zika virus disease or Zika is a disease caused by Zika virus that is spread to people primarily through the bite of an infected Aedes species mosquito. The most common or prominent symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting for several days to a week after being bitten by an infected mosquito. People usually don’t...
Wounds of the horses foot are common, and many are simple and heal without untoward consequences. Unfortunately, others may cause lasting changes in hoof function, and sometimes even be life threatening. The term foot describes the hoof and all structures contained within it. It is part of the appendicular skeleton and as such most of the same elements, i.e. bones, joints, tendons and ligaments encased by the integument. What makes the foot different is its integument the hoof because of its...
Performance horses compete in a wide variety of athletic events ranging from high speed racing to 100-mile endurance rides. These types of exercise are known to induce oxidative stress, leading to the generation of free radicals. An increased generation of free radicals may induce lipid peroxidation and tissue damage in both the respiratory system and working muscle. This is particularly true if the animal has a deficient or impaired antioxidant status. Reddy et al. (1998) studied...
A strong, well-conformed and developed musculoskeletal system is essential to provide structural support and limb soundness in exercising horses of all ages. These needs are greatest in the athletic horse to withstand the loading, strain and concussive forces imposed on bones and joint structures. Bone and joint injuries account for up to 70% of the downtime or lost training days in racing and equestrian event horses, with the type of musculo-skeletal injury changing during a horse’s...
Mycotoxins are toxic chemical compounds produced by some fungi as a defence system when they are threatened. Horses are highly exposed to mycotoxins due to the variety of feedstuffs included in their ration. Mycotoxicosis severity depends on duration of exposure, number of mycotoxins in presence, housing conditions and health status of the horses. Mycotoxicosis may lead to immunosuppression, reduction of the athletic performances, cancers, and sudden death. Horse stalls contain high quantity...
I am from Pakistan. There is a very common disease in horses called Glanders. It is a very dangerous disease leading to great economic losses and if a horse is affected it may cause problems to human beings. Is there any preventive measure to stop this disease in horse sheds and to completely cure it if this disease attacks any animal? Should the affected horse be separated from healthy horses? if someone could guide me more about this dangerous disease in horses, I wil be very...

ABSTRACT
This report describes the first Brazilian equine herpesvirus type 1 (EHV-1) isolation from a single fatal equine herpes myeloencephalopathy case in a mare. The isolation of EHV-1 was confirmed from the first passage of cerebrospinal fluid (CSF) sample in Vero cells by PCR and virus neutralization assay. As virus isolation from CSF is unlikely to be successful, as has been shown in several case reports, this circumstantial evidence suggests...
In April, the equine world was shocked when 21 elite polo horses at a Florida championship polo match died within minutes of each other. Initial reports are that the horses likely died from an overdose of selenium that came from a veterinary mineral supplement given to the horses a few hours before they died. Who is at fault is still being determined, and other causes of death are being discussed by some. Due to the widespread coverage of the tragedy, horse...
When a mare becomes pregnant, owners should discuss their mare's individual nutritional and exercise needs with their veterinarian. Typically, the first four months of a mare's pregnancy are not that demanding. At five, seven, and nine months of pregnancy, it is recommended mares in the US should receive a rhinopneumonitis (Equine Herpes virus) vaccine to help prevent abortion. At 30 days before giving birth, veterinarians recommend that mares in North America receive a standard...
Four clinical syndromes have been attributed to equine herpes virus-1 (EHV-1): respiratory disease in younger horses, abortion in pregnant mares, stillbirth or weakness in newborn foals and paralysis ( equine herpes virus myeloencephalopathy (EHM)).
EHM has been identified more frequently in recent years. Knowledge gained through dealing with outbreaks of the disease is now available in a 74 page report published by the USDA Animal and Plant Health Inspection Services, Centers for...
North America is free of the African horse sickness virus, yet this disease poses an important threat should an infected horse or a biting midge that harbors the virus be introduced.
African horse sickness (AHS) is the most lethal disease known to horses. Fortunately for American horses, AHS is currently enzootic, meaning only a limited number of cases occur each year, in sub-Saharan Africa. However incursions into southern Europe, the Middle East, and even the Indian subcontinent...
In recent years, there have been multiple incidences of major floods in the Midwest of the US as a result of hurricanes and large storms. These floods pose a major risk to humans and animals alike. Horses in pastures or barns that are flooded are at risk of injury or disease from many different sources Mud is a serious hazard for stranded horses. They can become trapped and fracture a limb or seriously injure themselves while struggling to free themselves...
1 Organize the clutter. • Clean your tack room and grooming supplies throwing out items that are worn or broken. • Clean up aisle ways and indoor arenas. • Put stall fans and light weight sheets in storage and replace sheets with winter blankets. Inspect blankets and repair if needed. 2 Inventory medicine and cleaning/grooming...
Potomac horse fever is a bacterial disease that is caused by Neorickettsia risticii (formerly Ehrilichia risticii). This disease has been known by a variety of other names including: equine monocytic ehrlichiosis, equine ehrlichial colitis, and acute equine diarrhea syndrome to name a few. The disease was first recognized in the late 1970’s in the Potomac River Valley of Maryland and has since been identified in most of the contiguous United States, parts...
Background
Fungal keratitis is a serious and painful corneal disease that is caused by fungal infection. Fungal keratitis in horses is a well-known and frustrating clinical problem and accounts for 31% of equine infectious keratitis. Under the best circumstances, the disease requires prolonged and expensive treatment; whereas under the worst circumstances, it can result in blindness or the need for enucleation.
Horses live in...
Neonatal isoerythrolysis (NI) is an uncommon, complex disorder of newborn foals that results from a blood group incompatibility that exists between the dam and the foal. NI occurs after the foal suckles and absorbs antibodies from the mare's colostrum, which then attack the foal's red blood cells. This results in destruction of the red blood cells of the foal and subsequent anemia (decrease in red blood cells).
Red blood cells (also known as erythrocytes) are crucial in the...
