Disease outbreaks in horses refer to the occurrence and spread of infectious diseases within equine populations. These outbreaks can be caused by various pathogens, including bacteria, viruses, and parasites, and can lead to significant health issues in affected horses. Common diseases that may result in outbreaks include equine influenza, equine herpesvirus, strangles, and equine infectious anemia. The transmission of these diseases can occur through direct contact, environmental exposure, or vectors such as insects. Disease outbreaks can have substantial impacts on horse health, welfare, and the equine industry as a whole. This page compiles peer-reviewed research studies and scholarly articles that explore the epidemiology, transmission dynamics, and management strategies associated with disease outbreaks in equine populations.
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.

Pauli BU, Rossi Straub R.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 ...
Neuvonen E, Estola T.A serological survey on the occurrence of group-specific chlamydial antibodies in random sera of Finnish sheep, cattle and horses was performed. The whole material consisted of 1347 serum samples, including 432 ovine, 454 bovine and 461 equine sera. The sera were sent to the laboratory for various serological tests during 1968–1972. Of the ovine sera 9.5%, bovine 12.8 % and equine 7.1 % showed a titer ≥ 1:16 in the complement fixation test. No definite geographic differences could be found in the distribution of the herds which showed positive results. The ubiquity of chlamydial infections...
Terpstra C.The aetiology, symptoms, diagnosis and control of African horse sickness are described. Special attention is paid to the introduction and epizootiology of the disease in Spain and its consequences in respect to the international trade of horses.
