Topic:Diagnosis
Diagnosis in horses involves the systematic identification of diseases and conditions affecting equine health. This process relies on a combination of clinical evaluations, laboratory tests, imaging techniques, and other diagnostic tools to assess the health status of horses. Veterinarians utilize these methods to identify symptoms, determine the underlying causes of health issues, and formulate appropriate treatment plans. Diagnostic procedures in equine medicine can include blood tests, ultrasound, radiography, endoscopy, and more specialized tests such as genetic screening or advanced imaging modalities like MRI and CT scans. This page aggregates peer-reviewed research studies and scholarly articles that explore various diagnostic techniques, their applications, and advancements in the field of equine veterinary medicine.
Comparison of four horse herpesviruses. Four equine herpesviruses (equine abortion virus, equine herpesvirus types 2 and 3, and equine cytomegalovirus) were compared. The equine abortion virus did not cross-neutralize with any of the other viruses, but the other three did show varying degrees of cross-neutralization among themselves. Equine abortion virus grew more quickly in tissue cultures than did the others, and attained higher titers of infectivity in the culture fluid; it also formed plaques in a wider range of tissue culture species, although the other three were not specific for one tissue culture system only, in that they w...
A comparative study of the temporal patterns of cutaneous water vapour loss from some domesticated mammals with epitrichial sweat glands. 1. The temporal patterns of cutaneous water vapour loss from the skin of the sheep, goat, ox, horse, donkey and llama during exposure to 40°C Ta and during i.v. injections and infusions of adrenaline are examined.
2. It is concluded that there are marked species variations in the extent to which the discharge of sweat is affected by periodic contractions of the myoepithelium, or by simple displacement of fluid from the filled lumen as more fluid is secreted into it.
Equine isoerythrolysis–clinical pathological observations and transfusion of dam’s red blood cells to her foal. Clinical pathological investigations in a case of equine isoerythrolysis are reported. Plasma and milk from the dam strongly agglutinated the foal's red blood cells at fifth day post partum. Red blood cells from one liter of the mare's blood were separated from plasma and after three successive washings with saline were successfully transfused into the foal. Elevated plasma transaminase activity, hypoglycemia, hypogammaglobinemia, and renal embarrassment were observed in this foal. The changes in the various plasma constituents are discussed.
An equine intersex with unilateral gonadal agenesis. Cytogenetic and histological studies have been carried out on an intersex horse which was clinically diagnosed as a cryptorchid. The horse had the general conformation of a stallion but the external genitalia included a well developed vulva and a penis. The right testis which was descended was devoid of germ cells and the left "gonad" located in the cavum vaginale contained neither testicular nor ovarian tissue. The male duct system on both sides were relatively well developed despite the absence of a testis on the left side. Chromosome analysis on cultured cells from the descended testis reve...
Electron microscopy of equine infectious anemia virus. Equine infectious anemia (EIA) virus was observed in thin sections of infected cultured horse leukocytes by electron microscopy. The virus particles had a spherical shape and were between 80 and 120 nm in diameter. Most of them contained an electron-dense nucleoid 40 to 60 nm in diameter. They were observed to form by a process of budding from the plasma membrane and appeared to have thin surface projections. The particles described were not detected in uninfected cultured cells, and their appearance could be prevented by adding EIA immune serum to the inoculum. The implications of these findi...
