| simulation studies of african horse sickness and culicoides imicola (diptera:ceratopogonidae). | a simulation model of african horse sickness in spain was developed to investigate what factors affect the likelihood of an epidemic after the introduction of the virus. the model included 2 host species (horses and donkeys) and 1 vector species (culicoides imicola kieffer). latin hypercube sampling was used for sensitivity analysis of the model, to include uncertainty in parameter estimates. in general, if an epidemic occurred most hosts were infected. the peak prevalence in midges was low, and ... | 1996 | 8667377 |
| simulation studies of vaccination strategies in african horse sickness. | a simulation model including two hosts (horses and donkeys) and one vector (culicoides imicola) for african horse sickness in spain is extended to consider vaccination strategies. if hosts were protected prior to virus introduction, elimination of simulated epidemics was related nonlinearly to the fraction protected. protecting donkeys as well as horses increased the effectiveness of vaccination. prevention of 50% of epidemics required 75% coverage of horses and donkeys or 90% coverage of horses ... | 1997 | 9160519 |
| simulation studies of african horse sickness in spain. | factors affecting epidemics of african horse sickness in spain were studied using a mathematical model. the model examined the likelihood of an epidemic after the introduction of the virus, and the effectiveness of vaccination strategies. two host species (horses and donkeys) and one vector species (the biting midge culicoides imicola) were included. a stratified random sampling method (latin hypercube sampling) was used for sensitivity analysis of the likelihood of an epidemic. systematic varia ... | 1998 | 9785500 |
| risk of introducing african horse sickness virus into the netherlands by international equine movements. | african horse sickness (ahs) is a vector-borne viral disease of equines that is transmitted by culicoides spp. and can have severe consequences for the horse industry in affected territories. a study was performed to assess the risk of introducing ahs virus (ahsv) into the netherlands (p_ahs) by international equine movements. the goal of this study was to provide more insight into (a) the regions and equine species that contribute most to this risk, (b) the seasonal variation in this risk, and ... | 2012 | 22341773 |
| bloodmeal analysis in culicoides midges collected near horses, donkeys and zebras in the eastern cape, south africa. | an upsurge in african horse sickness (ahs) in the eastern cape, south africa, from 2006 led to an epidemiological reassessment of the disease there. light trapping surveys carried out near horses, donkeys and zebras in 2014-2016 collected 39 species of culicoides midge (diptera: ceratopogonidae) that are potential vectors of ahs. to establish if these midges fed on equids, dna sequences were obtained from the gut contents of 52 female midges (35 freshly blood-fed, 13 gravid and four parous), rep ... | 2019 | 31099060 |
