Wesselsbron Disease Virus Associated with Abortions in Goats in Botswana

Historical and Epidemiological Aspects of Some Human Diseases Just to Zika Virus, a Short Review

“…The virus was isolated in 1989 for the first time in Madagascar from Aedes including A. caballus and A. circumluteolus (Mushi et al 1998, CDC 2016, Wesselsbron 2007. Serological studies in man have been investigated by haemagglutination inhibition assay (Morvan et al1990).…”

Theriogenology of Sheep and Goats

“…Although the primary vector are mosquitoes of Aedes genus transmission from aerosols produced from infected tissues may occur. 6,172 Family Reoviridae: Bluetongue Virus Bluetongue virus, genus Orbivirus, family Reoviridae, has at least 25 serotypes and occurs throughout tropical, subtropical, and some temperate regions of the world, where it causes disease in fine-wooled and mutton breeds of sheep. 172 Sick lambs may have neurologic signs and the placenta may have hydrops amnion.…”

Epidemiology and Emergence of Schmallenberg Virus Part 1: Origin, Transmission and Differential Diagnosis

“…Newborn lambs and kids are most susceptible, and it is often accompanied by a high mortality rate [112,115]. Outbreaks of congenital abnormalities in foetal or newborn ruminants, musculoskeletal deformities, neonatal deaths [112], abortion in adult animals [31,50,112] as well as hydropsamnii [116] in ewes, stillbirths and mummified foetuses [31] have been related. The main lesions found in foetuses are arthrogryposis, brachygnathia inferior, hydranencephaly, hydranencephaly, porencephaly, cerebellar hypoplasia [31], hypoplasia or segmental aplasia of the spinal cord and neurogenic muscular atrophy [116].…”

“…This virus affects sheep, goats and sporadically cattle [50,111]. Infection in adult animals and calves is usually subclinical or inapparent [112][113][114], although in sheep with preexisting liver disease clinical findings can be more expressive and severe. Newborn lambs and kids are most susceptible, and it is often accompanied by a high mortality rate [112,115].…”
