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.
Morgante O, Vance HN, Shemanchuk JA, Windsor R.The epizootic of equine encephalomyelitis in 1965 in Alberta was proved to be due to Western Encephalomyelitis virus infection by serological findings and virus isolations.Sixty-three horses of 88 tested, showed a diagnostic rise of CF antibodies to Western Encephalomyelitis virus. Western Encephalomyelitis virus was isolated from 5 brains of horses. Homologous antibodies were shown in 3 of these animals, the only ones from which blood specimens were received. For the first time virological evidence is given that Western Encephalomyelitis virus infection in horses is found in more areas of Alb...
Rossdale PD, Pattle RE, Mahaffey LW.A SYNDROME in newborn thoroughbred foals, characterized by irregular respiration, convulsions, and lung pathology, has been described already1, and its resemblance to the respiratory distress syndrome of the newborn human noted. This latter condition is associated with the absence of the surface active lung lining complex, or lung surfactant2; this absence can be investigated by observation of bubbles obtained from the lung3. From normal lungs bubbles of very low surface tension which show great stability in air-saturated water can be obtained4,5. The present case demonstrates the common facto...
Ludwig EK, Byron CR, Lahmers KK, Santos MP.An adult horse was diagnosed with a frontal and caudal maxillary sinus lipoma, which was surgically removed. This is the first known report of a sinus lipoma in a horse. Lipomas should be considered in the differential diagnoses of equine sinus masses; complete surgical excision appears to be curative. Un cheval adulte a été diagnostiqué avec un lipome du sinus maxillaire frontal et caudal qui a été enlevé par chirurgie. Il s’agit du premier rapport d’un lipome de sinus chez un cheval. Les lipomes devraient être considérés dans les diagnostics différentiels des masses des sinus ...
Puotunen-Reinert A, Huskamp B.A retrospective study on surgical cases of colic in horses (n = 216) revealed that 42 (19.4%) developed post-surgical diarrhoea. Salmonella spp. were isolated in 6 (16.2%) of the cases (n = 37) exhibiting diarrhoea. In 35.7% of the cases (n = 42) recovery from surgery was disturbed by other complications; 23.8% (10/42) died, 2 of which from primary acute diarrhoea due to salmonellosis. Most of the outbreaks of diarrhoea occurred in winter and spring. From the associated variables examined, the duration of colic signs revealed a significant difference between the cases which developed acute pos...
Farchati H, Merlin A, Saussac M, Dornier X, Dhollande M, Garon D, Tapprest J, Sala C.Identifying and tracking equines are key activities in equine health prevention. France is one of the few European countries with an operational centralized database that records information on equines, owners, and keepers but not on the location and keeping conditions of equines. The objective of our study was to collect information on keeping habits of equines and the relative location of a wide range of equines, owners, and keepers and discuss their implication for surveillance and control of outbreak improvement. A national email survey was conducted among the 1.9% of people registered as ...
