the prevalence of different african horsesickness virus serotypes in the onderstepoort area near pretoria, during an outbreak of african horsesickness in south africa in 1995/1996.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 horses died of suspected ahs. virus isolation and typing was done from blood and/or organ samples of 21 suspected cases as well as from five zebra which were kept in the area. virus was isolated from 14 of the 21 suspected cases but not from the zebra. ...200010843324
the first reported case of equine nocardioform placentitis in south africa.since the late 1980s a distinct form of focally-extensive mucoid to mucopurulent uterine body chronic placentitis,caused by nocardioform organisms, hasbeen recognised in horses in the usa state of kentucky and possibly in other areas. this disease has led to increasing numbers of foal losses from late abortions, still-births, prematurity, or early neonatal deaths. the foals are usually not infected, but may be small or emaciated. modes of infection and transmission are as yet unknown. nocardia s ...200112219921
lateral transmission of equine arteritis virus among lipizzaner stallions in south africa.a serological study conducted in 1995 revealed that 7 stallions at the lipizzaner centre, gauteng, south africa, were seropositive for antibody to equine arteritis virus (eav). a lipizzaner stallion imported into south africa from yugoslavia in 1981 had previously (1988) been confirmed to be an eav carrier. despite being placed under life-long breeding quarantine, eav had been transmitted between stallions at the lipizzaner centre.200314515961
molecular epidemiology of the african horse sickness virus s10 gene.between 2004 and 2006, 145 african horse sickness viruses (ahsv) were isolated from blood and organ samples submitted from south africa to the faculty of veterinary science, university of pretoria. all nine serotypes were represented, with a range of 3-60 isolates per serotype. the rna small segment 10 (s10) nucleotide sequences of these isolates were determined and the phylogeny investigated. ahsv, bluetongue virus (btv) and equine encephalosis virus (eev) all formed monophyletic groups and btv ...200818420793
