Development of a toolkit for African horse sickness : identification of Culicoides vectors from Namibia and detection of African horse sickness virus
(North-West University (South Africa), Potchefstroom Campus, 2016)African horse sickness (AHS) is a non-contagious, viral, insect-borne disease of equids and this disease is caused by the African horse sickness virus (AHSV). The virus is part of the family Reoviridae of the genus Orbivirus. ... -
Development of real-time RT-PCR assays for detection and typing of epizootic haemorrhagic disease virus
(Wiley, 2017)Epizootic haemorrhagic disease virus (EHDV) is an emerging arboviral pathogen of wild and domestic ruminants worldwide. It is closely related to bluetongue virus (BTV) and is transmitted by adult females of competent ... -
A historical perspective on the prevalence, distribution and influence of African Horse Sickness in Namibia
(School for Basic Sciences, Vaal Triangle Campus, North-West University, 2017)African Horse Sickness (AHS) is a devastating, non-contagious, infectious, insect-borne disease of equids. AHS is endemic to sub-Saharan Africa. Culicoides midges (Diptera: Ceratopogonidae) act as vectors for the transmission ... -
A multidisciplinary assessment of the distribution of African horse sickness in Namibia
(North-West University (South Africa), Potchefstroom Campus, 2015)African horse sickness (AHS) is the most lethal infectious, non-contagious, vector-borne disease of equids and accordingly has been declared notifiable by the OIE – World Animal Health Organisation. African horse sickness ... -
Non-structural protein NS3/NS3a is required for propagation of bluetongue virus in Culicoides sonorensis
(BioMed Central, 2015)Background: Bluetongue virus (BTV) causes non-contagious haemorrhagic disease in ruminants and is transmitted by Culicoides spp. biting midges. BTV encodes four non-structural proteins of which NS3/NS3a is functional in ... -
The occurrence of African horse sickness in Hartmann's mountain zebra and its Culicoides vector in the south–western Khomas Region, Namibia
(North-West University, 2011)African horse sickness (AHS) was reported in the south-western Khomas Region, central Namibia (22° 24.063´ S, 17° 01.791´ E; 23° 32.617´ S, 15° 53.870´ E), contrary to expectations that the arid conditions in the area ... -
Occurrence of Culicoides species (Diptera: Ceratopogonidae) in the Khomas region of Namibia during the winter months
(Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise G. Caporale, 2012)Although African horse sickness (AHS) is considered to be endemic in Namibia, limited data on its Culicoides midge vector (Diptera: Ceratopogonidae) are available. The principal study objective was to determine the presence, ... -
A review of knowledge gaps and tools for orbivirus research
(Mary Ann Liebert, Inc, 2015)Although recognized as causing emerging and re-emerging disease outbreaks worldwide since the late 1800s, there has been growing interest in the United States and Europe in recent years in orbiviruses, their insect vectors, ... -
Vector competence is strongly affected by a small deletion or point mutations in bluetongue virus
(BMC, 2019)Background Transmission of vector-borne virus by insects is a complex mechanism consisting of many different processes; viremia in the host, uptake, infection and dissemination in the vector, and delivery of virus during ...
