In addition, most horse shows and events require a negative Coggins test. Most countries require a negative test result before allowing an imported horse into the country. Horse owners should verify that all the horses at a breeding farm and or boarding facility have a negative Coggins test before using the services of the facility. [citation ...
Equine influenza is characterized by a very high rate of transmission among horses, and has a relatively short incubation time of one to three days. [6] Clinical signs of equine influenza include fever (up to 106 °F [41 °C]), nasal discharge, have a dry, hacking cough, depression, loss of appetite and weakness. [6]
Equid alphaherpesvirus 1, also called Equine herpesvirus 1 (EHV-1), is a virus of the family Herpesviridae that causes abortion, respiratory disease and occasionally neonatal mortality in horses. Initial spread of EHV-1 by a newly introduced horse through direct and indirect contact can lead to abortion and perinatal infection in up to 70 ...
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 ]
The unusual pericarditis cases and the unique single-eye uveitis cases were observed in horses of all ages, breeds, and sexes, were independent of any state of pregnancy, and that they occurred at the same time as the early and late fetal loss syndromes. From the first, therefore, MRLS was clearly not simply a pregnancy-related syndrome.
Among domesticated horses, colic is the leading cause of premature death. [3] The incidence of colic in the general horse population has been estimated between 4 [3] and 10 [4] percent over the course of the average lifespan. Clinical signs of colic generally require treatment by a veterinarian.
However, his markings are caused by a type of sabino patterning and he has been DNA-tested negative for the OLWS gene. Horses heterozygous for the Ile118Lys mutation on the equine EDNRB gene—carriers of lethal white syndrome—usually exhibit a white-spotting pattern called "frame", or "frame overo".
The most current theory is a result of a recent study that suggests it is caused by a pegivirus, referred to as Theiler's disease-associated virus (TDAV). [2] Eight horses that had received prophylactic botulinum antitoxin and developed subsequent signs of Theiler's disease were subjected to a test for a viral infection based on RNA sequencing techniques.
