Signs and symptoms of PHF include acute-onset fever, depression (sometimes profound), inappetence, mild colic-like symptoms, decreased manure production, profuse watery non-fetid diarrhea endotoxemia, edema due to protein imbalances, abortion by pregnant mares, and acute laminitis (20 to 40 percent of cases).
The most current theory is a result of a recent study that suggests it is caused by a pegivirus, referred to as Theiler's disease-associated virus (TDAV). [2] Eight horses that had received prophylactic botulinum antitoxin and developed subsequent signs of Theiler's disease were subjected to a test for a viral infection based on RNA sequencing techniques.
Diagnosing EPM can be challenging because the signs can vary significantly from horse to horse, and the symptoms can be similar to those of other CNS diseases. The only way to definitively diagnose EPM is through post-mortem testing, but there are ways to exclude other diseases and establish a basis for the EPM diagnosis.
A horse may be returned to work if symptoms have ceased and is no longer on NSAIDs or other prescribed drugs related to treatment of ER, this can otherwise can hide signs of another bout of ER. If NSAIDs or other treatment drugs are needed to keep the horse comfortable, or if the horse is reluctant to continue work, the animal is not yet ready ...
Equine viral arteritis (EVA) is a disease of horses caused by a virus of the species Alphaarterivirus equid, an RNA virus. [1] [2] It is the only species in the genus Alphaarterivirus, and that is the only genus in the Equarterivirinae subfamily. The virus which causes EVA was first isolated in 1953, but the disease has afflicted equine animals ...
Recurrent airway obstruction, also known as broken wind, heaves, wind-broke horse, or sometimes by the term usually reserved for humans, chronic obstructive pulmonary disease or disorder (COPD) – it is a respiratory disease or chronic condition of horses involving an allergic bronchitis characterised by wheezing, coughing and laboured breathing.
Horses are usually affected on the back, head, and neck where insects commonly bite, and the legs, which are commonly infected if the horse is kept in moist footing. [3] Initially, the horse will display a matted coat and bumps which will progress to crusty scabs and lesions. [4] The animal may also be pruritic and display signs of discomfort.
Lameness is a common veterinary problem in racehorses, sport horses, and pleasure horses. It is one of the most costly health problems for the equine industry, both monetarily for the cost of diagnosis and treatment, and for the cost of time off resulting in loss-of-use. [1]
