| investigations on outbreaks of african horse sickness in the surveillance zone in south africa. | confirmed outbreaks of african horse sickness (ahs) occurred in the surveillance zone of the western cape in 1999 and 2004, both of which led to a two-year suspension on the export of horses. light trap surveys in the outbreak areas showed that known vector competent culicoides species, notably c. imicola, were abundant and present in numbers equal to those in the traditional ahs endemic areas. isolations of ahs virus serotypes 1 and 7, equine encephalosis virus, and bluetongue virus from field- ... | 2006 | 17361773 |
| 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 ... | 2008 | 18420793 |
| natural bluetongue virus infection in alpacas in south africa. | bluetongue virus (btv) was sporadically isolated over a four year period (2010-2014) from several alpaca carcasses that were presented for necropsy at the western cape provincial veterinary laboratory, south africa. typically, the a ected animals had a history of acute dyspnoea and progressive weakness before death. consistent hydrothorax and severe lung oedema in all lead to a preliminary diagnosis of bluetongue, despite the absence of ulceration and hyperaemia of the oral mucosa which is chara ... | 2016 | 27723038 |
