Influenza A strains emerging from wild birds are a constant threat to South Africa's valuable ostrich industry. In 2004 and again in 2006, low pathogenicity avian influenza H5N2 strains introduced from a wild bird reservoir mutated in ostriches to hi

The origin of bluetongue (BT) is probably African and the disease was first recognised in South Africa in Merino sheep in the late 18th Century. Diagnostic and research findings for a number of years have been summarised to obtain data relevant to th

Field-collected Culicoides were fed on sheep blood-virus mixtures, each containing one of four live-attenuated vaccine strains of bluetongue virus (BTV), namely: BTV-1, BTV-4, BTV-9, and BTV-16. A South African field isolate of BTV-1 was used as the

Pigeon paramyxovirus type 1 (PPMV-1), a variant of Newcastle disease virus that primarily affects doves and pigeons has been isolated in South Africa since the mid-1980s. Phylogenetic evidence indicates that pigeon paramyxovirus type 1 viruses were i

In an intensive ostrich farming area in South Africa with a history of ostrich influenza outbreaks, we conducted a survey of avian influenza virus (AIV) and Newcastle disease virus (NDV) in wild aquatic birds. During late autumn and winter 1998, the

During 1995/1996 parts of South Africa experienced exceptionally high rainfall. Large numbers of Culicoides midges were seen and an outbreak of African horsesickness (AHS) followed. In the Onderstepoort area, near Pretoria in Gauteng, a number of hor

The presence of virulent Newcastle disease virus (NDV) since the 1993-94 epidemic in southern Africa holds major implications for the export of ostrich products from this region. A challenge experiment with this field strain was conducted in open-air

In December 1995 to March 1996 and the early summer of 1997 South Africa experienced above average rainfall which favoured the occurrence of Culicoides transmitted diseases. During this period several outbreaks of an uncommon disease of cattle occurr
