Abstract
Bluetongue (BT) causes an economic loss of $3 billion every year in the world. After two serious occurrences of BT (bluetongue virus [BTV] occurrence in 2006 and 2015), France has been controlling for decades, but it has not been eradicated. As the largest live cattle export market in the world, France is also one of the major exporters of breeding animals and genetic materials in the world. The biosafety of its exported cattle and products has always been a concern. The scenario tree quantitative model was used to analyze the risk of BTV release from French exported live cattle and bovine semen. The results showed that with the increase in vaccination coverage rates, the risk decreased. If the vaccine coverage is 0%, the areas with the highest average risk probability of BTV-4 and BTV-8 release from exported live cattle were Haute-Savoie and Puy-de-Dôme, and the risk was 2.96 × 10-4 and 4.25 × 10-4 , respectively. When the vaccine coverage was 90%, the risk probability of BTV-4 and BTV-8 release from exported live cattle was 2.96 × 10-5 and 4.24 × 10-5 , respectively. The average probability of BTV-8 release from bovine semen was 1.09 × 10-10 . Sensitivity analysis showed that the probability of false negative polymerase chain reaction (PCR) test and the probability of BT infection in the bull breeding station had an impact on the model. The identification of high-risk areas and the discovery of key control measures provide a reference for decision makers to assess the risk of French exports of live cattle and bovine semen.

Molecular epidemiology of bluetongue virus serotype 1 circulating in Italy and its connection with northern Africa. INFECTION GENETICS AND EVOLUTION 2014; 28:144-9. [PMID: 25239524 DOI: 10.1016/j.meegid.2014.09.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2014] [Revised: 09/02/2014] [Accepted: 09/10/2014] [Indexed: 10/24/2022]
Abstract
Western BTV-1 emerged in the Mediterranean basin in 2006 and it has since been isolated in southern and northern European countries. Six BTV-1 strains isolated from infected sheep in Italy between 2006 and 2013 and a BTV-1 strain isolated from an infected sheep in Tunisia in 2011 were fully sequenced. The seven strains were shown to be nearly identical in each gene segment. The Seg-2 sequences of the BTV-1 strains group according to the year of isolation reflecting the time of BTV incursions in Italy. Combined results suggest that BTV-1 strains isolated in Sardinia, Sicily and mainland Italy in 2012 and 2013 have a direct northern African origin. The Italian strains originated from a strain closely related to a BTV-1 strain isolated in Tunisia in 2011. Better surveillance programs with northern and sub-Saharan African countries should be implemented making the control of spread of BTV easier and effective.
