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.
Surgical treatment of osteomyelitis in the metacarpal and metatarsal bones of the horse. The case histories of four horses with osteomyelitis involving the metacarpal and metatarsal bones are reviewed and the surgical treatments discussed. The horses recovered after curettage of all infected tissue and post operative drainage. The role of antibiotics in treatment is considered and reference is made to the acute treatment of deep wounds to avoid osteomyelitis.
Equine grass sickness: serologic evidence of association with Clostridium perfringens type A enterotoxin. Clostridium perfringens type A enterotoxin seroneutralization was carried out on sera from 50 horses recovered from grass sickness and from 100 other horses with no record of having had the disease. Of the affected horses, 70% had seroneutralizating titers higher than 1:64, half of these being equal or higher than 1:128. More than 88% of the horses with no record of grass sickness had titers lower than 1:64. These data support the theory of association between C perfringens type A toxins and grass sickness.

Maintenance of foals with combined immunodeficiency: causes and control of secondary infections. Sixty-six cases of combined immunodeficiency (CID) in foals were studied to determine the most prevalent causes of infection and death. Lesions of the respiratory system were observed in 59 of the foals and were attributable to infection with equine adenovirus. Pneumocystis carinii, and bacteria. Significant lesions were also observed in liver, pancreas, intestines, heart, and kidneys. Maintenance of foals with CID for experimental purposes is directed at the prevention and control of these secondary infections. Adenovirus can be controlled by administration of horse plasma containing high tit...
Analysis of mechanisms regulating the expression of parental alleles at the GPD locus in mule erythrocytes. Erythrocyte glucose-6-phosphate dehydrogenase (G6PD) was examined by 13% starch gel electrophoresis in 74 mules (42 females and 32 males), 35 donkeys, and ten horses. The quantitative expression of the parental alleles at the Gpd locus varies greatly in female mules from the hemizygous expression of the maternal allele to that of the paternal. The data obtained indicate that the X chromosomes are randomly inactivated in females mules. No selective advantage of a cell population with a maternally (or paternally) derived X active was found in female mule erythrocytes. It is suggested that the ph...
Failure to propagate equine infectious anemia virus in mosquitoes and Culicoides variipennis. Laboratory-colonized mosquitoes, Culex tarsalis, aedes aegypti, Culiseta inornata, and Anopheles free-borni, and the biting gnat, Culicoides variipennis, were exposed to equine infectious anemia virus. Exposure to the virus was by intrathoracic inoculation for mosquitoes and by oral ingestion of an infective blood meal through a membrane for C variipennis. After various intervals, groups of 15 to 20 insects were homogenized and inoculated into susceptible ponies. Positive immunodiffusion test results were used as criterion for equine infectious anemia infection in ponies. Virus was not detecte...
