Equine encephalosis virus (EEV) is a species of virus the Orbivirus genus, and a member of the Reoviridae family, related to African horse sickness virus (AHSV) and Bluetongue virus (BTV). [ 1 ] First described in South Africa over a hundred years ago by Arnold Theiler , EEV is the causative agent of equine encephalosis ( EE ), an arthropod ...
Obstetric ultrasonography of twins at a gestational age of almost 9 weeks. The mother’s and the twins’ bodies have a higher echogenicity than the amniotic fluid around them. The standard representation is brighter color for higher echogenicity, giving the almost anechoic fluid an almost black appearance.
Eastern equine encephalitis (EEE), also called triple E and sleeping sickness, is a viral disease caused mainly by the Eastern equine encephalitis virus (EEEV). Most infections in humans are asymptomatic, but about 5% of the time the infection progresses to severe neuroinvasive disease.
Chronic: The horse tires easily and is unsuitable for work. The horse may have a recurrent fever and anemia, and may relapse to the subacute or acute form even several years after the original attack. [citation needed] A horse may also not appear to have any symptoms, yet still tests positive for EIA antibodies.
Ideally, horses that are showing symptoms should be completely quarantined. The recommended quarantined period is at least 21 days. [ 11 ] Another facet of EHV-1 control is to be aware of the potential for spreading the virus via equipment, and transmission, via human contact, between horses.
Horses very rarely conceive twins or carry them to full term. The odds for this occurrence are only 1 in 10,000, the organization said. A mustang gave birth to rare twin colts at Banditas Wild ...
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". [5] [7] [9] [13] Frame is characterized by jagged, sharply defined, horizontally oriented white patches that run along the horse's neck, shoulder, flank, and ...
Equine viral arteritis (EVA) is a disease of horses caused by a virus of the species Alphaarterivirus equid, an RNA virus. [1] [2] It is the only species in the genus Alphaarterivirus, and that is the only genus in the Equarterivirinae subfamily. The virus which causes EVA was first isolated in 1953, but the disease has afflicted equine animals ...
