VIROLOGY JOURNAL 02/07/16 Requirements and comparative analysis of reverse genetics for bluetongue virus (BTV) and African horse sickness virus (AHSV)

These viruses are spread by specific species of Culicoides biting midges. Outbreaks and geographic expansion of affected areas are associated to various factors, including climate change [1, 2], and the presence of competent biting Culicoides midges [3]. Culicoides species in countries with a moderate climate are competent insect vectors for BTV [4, 5, 6]. This implies that countries historically free of disease are probably at risk for BT and other midge borne diseases [7]. The prototype bluetongue virus (BTV) and African horse sickness virus (AHSV) are the best studied orbiviruses, reviewed in [8]. For a long time, research on orbiviruses has been hampered by the lack of reverse genetics systems.

RG has also been used to develop very promising novel vaccines for orbiviruses.

This study is the first to utilise WHO cone bioassays to investigate the mortality rate in Culicoides caused by exposure to insecticide treated nets (ITNs).

PLOS 12/11/14 Worldwide Niche and Future Potential Distribution of Culicoides imicola, a Major Vector of Bluetongue and African Horse Sickness Viruses. Abstract We modelled the ecoclimatic niche of Culicoides imicola, a major arthropod vector of midge-borne viral pathogens affecting ruminants and equids, at fine scale and on a global extent, so as to provide insight into current and future risks of disease epizootics, and increase current knowledge of the species' ecology.

PLOS 12/11/14 Worldwide Niche and Future Potential Distribution of Culicoides imicola, a Major Vector of Bluetongue and African Horse Sickness Viruses

Based on the known distribution and ecology of C. imicola, the species' response to monthly climatic conditions was characterised using CLIMEX with 10′ spatial resolution climatic datasets. The species' climatic niche was projected worldwide and under future climatic scenarios. The validated model highlights the role of irrigation in supporting the occurrence of C. imicola in arid regions. In Europe, the modelled potential distribution of C. imicola extended further West than its reported distribution, raising questions regarding ongoing process of colonization and non-climatic habitat factors.

MERCK VETERINARY MANUAL - African Horse Sickness: Introduction

It is characterized by clinical signs and lesions associated with respiratory and circulatory impairment. Etiology and Epidemiology AHS is caused by an orbivirus, 55–70 nm in diameter, of the family Reoviridae. There are 9 immunologically distinct types. The virus is inactivated at a pH of <6 or ≥12, or by formalin, β-propiolactone, acetylethyleneimine derivatives, or radiation. Appearance of AHS may be preceded by seasons of heavy rain that alternate with hot and dry climatic conditions, which favor transmission. Transmission Culicoides spp are the principal vectors of all 9 serotypes of AHS virus, with C imicola being the most important. Clinical Findings and Lesions Mortality depends on virulence of the viral strain and susceptibility of the host.

AFSCA 29/05/13 La Belgique obtient le statut «officiellement indemne de peste équine» Le 28 mai 2013, l’Organisation Mondiale de la Santé animale a reconnu officiellement le statut historiquement indemne de peste équine de la Belgique.

AFSCA 29/05/13 La Belgique obtient le statut «officiellement indemne de peste équine»

L’obtention de ce statut est le fruit d’un travail conjoint entre l’AFSCA et le secteur équin. Ce statut constitue un atout important pour la Belgique, il facilitera le commerce de chevaux vers les pays tiers ainsi que la participation des chevaux belges aux compétitions internationales organisées hors Europe. La peste équine est une maladie virale qui peut infecter toutes les espèces d’équidés, leurs croisements ainsi que certaines autres espèces animales.

Il ne s’agit pas d’une zoonose, l’homme n’est pas infecté sauf accidentellement (personnel de laboratoires). Le virus est endémique en Afrique.

PLOS 05/08/11 Transmission and Control of African Horse Sickness in The Netherlands: A Model Analysis

Since the closely related disease bluetongue established itself in The Netherlands in 2006, AHS is considered a potential threat for the Dutch horse population. A vector-host model that incorporates the current knowledge of the infection biology is used to explore the effect of different parameters on whether and how the disease will spread, and to assess the effect of control measures. The time of introduction is an important determinant whether and how the disease will spread, depending on temperature and vector season. Given an introduction in the most favourable and constant circumstances, our results identify the vector-to-host ratio as the most important factor, because of its high variability over the country.

Furthermore, a higher temperature accelerates the epidemic, while a higher horse density increases the extent of the epidemic. Figures Copyright: © 2011 Backer, Nodelijk.

Fièvre aphteuse, influenza aviaire ou encore fièvre catarrhale ovine, comme l'ont montré les crises sanitaires de la dernière décennie, il est essentiel de disposer de systèmes de lutte organisés et réactifs contre les agents pathogènes exotiques.

ANSES 22/05/12 Introduction de maladies animales exotiques en France : des recommandations pour améliorer la surveillance et la prévention

Afin d'identifier les maladies exotiques les plus à risque d'introduction en France et de préciser les modalités de lutte et de surveillance les plus adaptées contre ces agents, l'Anses s'est auto-saisie. Elle publie aujourd'hui les résultats de ses travaux et les recommandations qu'elle en tire. La santé des animaux est susceptible d'être menacée par divers agents pathogènes (bactéries, virus, parasites) dont certains peuvent également affecter la santé humaine (agents zoonotiques). Parmi ces agents pathogènes, un certain nombre sont présents sur le territoire métropolitain, d'autres circulent hors du territoire et sont dits "exotiques". Dans ce contexte, l'Anses a souhaité s'autosaisir.
