Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
Horses that develop purpura haemorrhagica usually have a recent history of strangles (infection with Streptococcus equi subsp. equi) or vaccination (intramuscular or intranasal) for strangles. It is thought to be caused by an auto-immune reaction where antibodies against the S. equi M- or R-protein cross-react with proteins on endothelial cells .
The first is Immune-Mediated Myositis (IMM). It may occur in response to a vaccine or infectious agent, where the immune system misinterprets the muscle cells as foreign and rapidly attacks them. Horses initially experience stiffness, weakness, and a decreased appetite followed by the rapid loss of 40% of muscle mass within 72 hours.
Glanders was a significant problem for civilian use of horses, as well. In the 18th-century veterinary hospital at the École Nationale Vétérinaire d'Alfort, glanders was the most common disease among their equine patients and the one most likely to cause death. [10]

[3] [4] Vaccines are categorised into conventional and next generation vaccines. [5] [6] Animal vaccines have been found to be the most cost effective and sustainable methods of controlling infectious veterinary diseases. [6] In 2017, the veterinary vaccine industry was valued at US$7 billion and it is predicted to reach US$9 billion in 2024. [7]
Vaccine for horses. In November 2012, a vaccine became available for horses. The vaccine is to be used in horses only, since, according to CSIRO veterinary pathologist Deborah Middleton, breaking the transmission cycle from flying foxes to horses prevents it from passing to humans, as well as, "a vaccine for people would take many more years."
