Topic:Clinical Symptoms
Clinical symptoms in horses encompass a range of observable signs that may indicate underlying health issues, such as disease, injury, or physiological stress. These symptoms can vary widely depending on the condition and may include changes in behavior, appetite, respiratory patterns, or physical appearance. Common clinical symptoms in horses include lameness, colic, coughing, nasal discharge, and changes in body temperature or heart rate. Identifying and interpreting these symptoms is an essential aspect of equine veterinary practice, as they provide critical information for diagnosis and management of health conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, assessment, and implications of clinical symptoms in equine health management.
Phycomycotic granuloma in horses in the Northern Territory. 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.

[Interstitial cell adenoma of the hypophysis with Cushing-like symptomatology in the horse]. A trabecular adenoma of the pars intermedia of the hypophysis was seen in a 13-year-old half-bred mare that presented symptoms corresponding to Cushing's disease of man. The spindle-shaped tumor cells were for the most part ‘light’, seldom ‘dark’. Both of them were characterized by well-developed rough endoplasmic reticulum, small Golgi apparatus, and typical secretory granules with a diameter of about 200 μm. The pituitary tumor and the symptoms were accompanied by increased plasma adenocorticotrophic hormone (ACTH) and by bilateral hyperplasia of the adrenal cortex. The tumor cells ...
Tyzzer’s disease in a foal. Light- and electron-microscopic observations. Tyzzer's disease was diagnosed in a 17-day-old foa l after the demonstra tion
of mu ltip le foci of hepat ic necro sis and organisms morphologically compatible with
Bacillus piliformis in hepa tocytes at the margins of the necrotic foci. Th e bac illi were
300 to 500 nm in diameter with occa sional giant bacilli 1000 nm in d iameter. Ma ny intranuclear organisms were seen, and a n a pparent sequence of nuclear penetration by these
organisms was demonstrated . There was hem orrhage in the hear t a nd inflamma tory
cha nges in the mesenteric lymph node . Enteritis was no t pre sent in the j...
