-
(University of Pretoria, 2005-12-01)Factors that determine the molecular basis of African horsesickness virus (AHSV) virulence are unclear. Several proteins and different events in the viral replication cycle together with different environmental factors are ...
-
(University of Pretoria, 2022)Viral genome segments are often under strong selective pressure to enhance the coding capacity of the genome, allowing expression of multiple proteins from a single mRNA. A second additional open reading frame, ORF2, was ...
-
(University of Pretoria, 2006-04-07)African horsesickness virus (AHSV) is a member of the Orbivirus genus and part of the family Reoviridae. It is a double stranded RNA virus with ten genome segments that encode seven structural and four nonstructural proteins. ...
-
(University of Pretoria, 2014-07)The highly infectious vector-borne disease African horse sickness (AHS) is caused by African horse sickness virus (AHSV), a non-enveloped dsRNA virus of major economic importance in South Africa. The AHSV virion has a ...
-
(University of Pretoria, 2017)Currently orbiviruses are recognised as causing worldwide emerging and re-emerging disease outbreaks including African horsesickness (AHS), a devastating disease of equids. AHS is endemic to sub-Saharan Africa, and of great ...
-
(University of Pretoria, 2009-04-16)African horsesickness (AHS), caused by the African horsesickness virus (AHSV) (Coetzer&Erasmus, 1994), has 10 segments of double stranded RNA (Verwoerd et al., 1970). These encode seven structural proteins, namely VP1, ...
-
(University of Pretoria, 2021)African horse sickness (AHS) is a non-contagious disease causing severe illness and mortality in infected horses, and is listed as a notifiable disease by the World Organisation for Animal Health. The orbivirus African ...
-
(University of Pretoria, 2007)African horsesickness virus (AHSV) is a dsRNA virus that belongs to the Orbivirus genus within the Reoviridae family. Each of the ten viral dsRNA segments encodes one virus-specific protein. During its life cycle AHSV ...
-
(University of Pretoria, 2014)African horsesickness virus (AHSV) is a member of the Orbivirus genus within the Reoviridae family and causes an acute disease in horses. AHSV encodes four non-structural proteins (NS1, NS2, NS3/NS3A), whose functions in ...
-
(University of Pretoria, 2019)African horse sickness virus (AHSV) is an arbovirus in the genus Orbivirus and the family Reoviridae known to successfully propagate in different species, such as mammalian hosts and insect vectors. In mammalian cells, ...
-
(University of Pretoria, 2013)African horse sickness is an equid disease caused by African horse sickness virus (AHSV). AHSV produces seven structural proteins that form the virion and four non-structural proteins with various roles during replication. ...
-
(University of Pretoria, 2006-11-30)The aims of this investigation were to compare the nonstructural proteins, NS3 and NS3A, of African horse sickness virus (AHSV) and to further characterize the cytotoxic properties of these proteins. NS3 and NS3A are encoded ...
-
(University of Pretoria, 2009-07-15)African horsesickness virus (AHSV) is a double-stranded RNA virus belonging to the Orbivirus genus in the Reoviridae family (Bremer et al., 1990; Calisher and Mertens, 1998). The virus is highly pathogenic and its mortality ...
-
(University of Pretoria, 2011-09-23)African horsesickness virus (AHSV), a member of the Orbivirus genus within the Reoviridae family, has a ten-segment double-stranded (ds)RNA genome that is encapsidated within a single non-enveloped virus particle. In ...
-
(University of Pretoria, 2010-10-25)African horsesickness (AHS), caused by African horsesickness virus (AHSV), is an infectious, non-contagious, insect-borne viral disease that affects members of the Equidae family. AHSV is a non-enveloped virus, consisting ...
-
The role of African horse sickness virus non-structural protein NS4 in virulence and host immunity (University of Pretoria, 2022)African horse sickness virus (AHSV) causes African horse sickness (AHS), a highly infectious vector-borne disease that impacts significantly on animal health. A live-attenuated vaccine is currently used to control AHS but ...
-
(University of Pretoria, 2011-09-23)The viral determinants of African horsesickness virus (AHSV) cytopathology are not well understood. Several AHSV proteins may play a role, including non-structural protein NS3, a cytotoxic membrane protein that localises ...
-
(University of Pretoria, 2011-09-08)The role of the non-structural protein NS3 in the viral life cycle of African horsesickness virus (AHSV) is an active area of research. It has been shown to be involved in the lytic and nonlytic mechanisms of viral release. ...
-
(University of Pretoria, 2020-04-02)African horse sickness is an economically important equid disease caused by African horse sickness virus (AHSV). Upon infection, the virus produces seven structural proteins that constitute the virus particle, and four ...
-
(University of Pretoria, 2022-06-29)A VND7 induction system in Arabidopsis was used to study plastid morphology at different time points during secondary cell wall deposition. We analyzed published transcriptomic and metabolic data to contextualize these ...
