    An outbreak of African horse sickness (AHS) caused by AHS virus type 1 occurred within the South African AHS surveillance zone during April and May 2016. The index case was detected by a private veterinarian through passive ...
  • Phylogenetic characterization of the Palyam serogroup orbiviruses 
    Ebersohn, Karen; Coetzee, Peter; Snyman, Louwrens Pieter; Swanepoel, Robert; Venter, Estelle Hildegard (MDPI Publishing, 2019-05)
    The Palyam serogroup orbiviruses are associated with abortion and teratogenesis in cattle and other ruminants. Of the 13 different serotypes that have been identified, the full genome sequence of only one, Kasba, has been ...
