Disease etiology in horses refers to the study of the causes and development of diseases within equine populations. It encompasses various factors, including genetic predisposition, environmental influences, infectious agents, and nutritional imbalances, that contribute to the onset and progression of diseases in horses. Understanding disease etiology is essential for identifying risk factors and implementing preventative measures in equine health management. This topic includes research on pathogen-host interactions, the impact of management practices on disease incidence, and the role of genetic and environmental factors in disease susceptibility. This page compiles peer-reviewed research studies and scholarly articles that explore the mechanisms, contributing factors, and implications of disease etiology in horses.
Lowe JE, Baldwin BH, Foote RH, Hillman RB, Kallfelz FA.Surgical thyroidectomies (Thx) were per-formed in 6 yearling grade horse colts, (3 males, 3 females). Five control colts (3 males, 2 females) were included and comparative studies were carried out for 67 weeks. The comparative measurements included rectal temperature, heart rate, feed consumption, packed cell volume, serum cholesterol, serum calcium, serum phosphorus, serum TO height, heart girth, body weight, epiphyseal plate closure and tooth eruption times. A thyroprotein supplement was fed to the Thx males during weeks 46 to 53. The Thx animals failed to grow in height, were sensi-tive to ...
Johnston KG, Henderson AW.Under the title “Equine Granuloma in the
Northern Territory of Australia” Lewis (1914)
gave an account of a disease of horses otherwise
known as “swamp cancer”. A variety of superficial sites are affected but these are rarely above
the level of the shoulder joint and principally
involve the lower legs and the ventral aspect of the
thoracoabdominal wall. The lesions on the legs are
granulating ulcers, those on the body are subcutaneous swellings and both are characterised by
the presence of conspicuous necrotic cores or
“kunkers” in the inflammatory tissue.

Wensvoort P, Steenbergen-Botterweg WA.When adipose tissues of horses and ponies affected with generalized steatitis were extracted by acetone, methanol and chloroform, non-extractable lipids were found to be present, which had become insoluble as a result of peroxidation and polymerization and had acquired autofluorescent characteristics. The origin of these lipids varies. Peroxidation occurs in three different lipid compartments, namely in the cytoplasm of the necrotized adipose cells, in the macrophagess and in the fat globules present in stroma.
Yamout SZ, Magdesian KG, Tokarz DA, le Jeune SS.This is a report of a 12-year-old Swedish Warmblood gelding with a ruptured esophageal pulsion diverticulum associated with atypical clinical signs of colic and septic peritonitis on presentation. The location of this diverticulum at the hiatus was unique and was most likely responsible for the unusual presentation of this horse. Diverticule de Zenker intrathoracique chez un cheval. Ceci est un rapport d’un hongre de race Swedish Warmblood âgé de 12 ans présentant un diverticule de Zenker perforé associé à des signes cliniques atypiques de coliques et de péritonite septique à la pré...
Ginther OJ, Almamun M, Shahiduzzaman AK, Beg MA.The mechanism for a reported temporal association between ovulation and a transient disruption in the periovulatory increase in LH concentrations was studied in nine mares treated with human chorionic gonadotropin when the preovulatory follicle was >/=32mm. Examinations for ovulation detection and blood collection were done at 2-h intervals and the results were retrospectively centralized to ovulation (Hour 0). Concentrations of LH began to increase (P<0.03) rapidly at Hour -18, decreased (P<0.04) between Hours 0 and 6, and again increased (P<0.0001) after Hour 12. A progressive de...
Schatzmann U, Girard P.This paper summarizes causes of cardiovascular complications. Treatment of drug related hypotension as well as etiology and therapy of cardiac arrest are discussed.
Kita J.Epidemiological observations on the course and spread of equine influenza in Poland during the 1969 epizootic were carried out. The dynamics of the spread of the disease in the country are shown graphically by voivodship. The disease incidence and mortality rates for the entire country are also shown. The highest incidence of disease and mortality rates were found to be in November 1969. A/equi-2/Warsaw/69 was identified as the causal virus. It caused the largest epizootic in the country since 1954.
Ullrich E, Selbitz HJ, Schieck R, Friedrich U, Schulz J.Clinical, bacteriological and serological examinations on a 6 years old pony mare were performed. Cytological alterations in the genital tract were also recorded. A cellular reaction was seen after infection with T. equigenitalis. This reaction is an evidence for infection but it is not specific for this organism. Cytological studies should be performed on mares especially in cases of latent infections to complete bacteriological examination and to prevent false positive or negative results.
