Preliminary studies on the use of solid-phase immunosorbent techniques for the rapid detection of Wesselsbron virus
(WSLV) IgM by haemagglutination-inhibition.
Differential diagnosis for flaviviruses, WNV, Wesselsbron virus
, SHUV, and equine encephalosis viruses was performed on all specimens, which were sent to other laboratories for testing for AHSV, equine herpes viruses, and rabies (5,6).
Studies on an outbreak of Wesselsbron virus
in the Free State Province, South Africa.
Comparative testing with Wesselsbron virus
, a closely related flavivirus, did not show cross-reactivity within the parameters of what we considered positive.
During the same period, 4.7 million doses of newly developed inactivated RVF vaccine and [approximately equal to]14 million doses of Wesselsbron virus
vaccine were sold (27,28,35).
The Wesselsbron virus
, a new arbovirus for Madagascar [in French].
Serum specimens were tested for immunoglobulin M (IgM) and IgG antibodies specific for DENV, West Nile virus (WNV), Wesselsbron virus
, Rift Valley fever virus, Bunyamwera virus, and CHIKV by IgM-antibody capture (MAC-ELISA) and IgG sandwich ELISA, respectively (11).
The first sample (November 3, 2004) contained no antibodies (OD ratio <2) to dengue viruses, West Nile virus, Wesselsbron virus
, Rift Valley fever virus, Bunyamwera virus, or Chikungunya virus (CHIKV).
All blood spot samples tested negative by enzyme-linked immunosorbent assay (ELISA) for certain antigens (i.e., dengue virus, West Nile virus, Chikungunya virus, and Wesselsbron virus
Three isolates obtained by the Onderstepoort Veterinary Institute, Pretoria, included the horse and ostrich isolates, which originated from the Regional Veterinary Laboratory, Stellenbosch, Western Cape Province, and a dog isolate, which originated from the Veterinary Investigation and Research Laboratory, Gaborone, Botswana, and was initially described as Wesselsbron virus
(WESSV) but was later found to be WNV (34; BJH Barnard, pers.
