“…Such phenomenon has already been identified in the USA where the reassortment between a EHDV-6 strain of unknown origin and a endemic strain of EHDV-2 generated a reassortant virus able to cause severe outbreaks in deer (Allison et al, 2010). More recently, the OIE Reference Laboratory for Bluetongue in Italy (Lorusso et al, 2013) identified a reassortant strain BTV-4/1 during outbreaks in sheep (Sardinia-2012) caused by BTV-1 and BTV-4.…”

“…Long distance spread of BTV from endemic regions to adjacent uninfected areas can occur via the wind‐borne dissemination of virus‐infected midges, especially over water (Sedda et al., ; Burgin et al., ). Thus, novel strains of BTV regularly are introduced by windborne midges from Indonesia to the ‘Top End’ of Australia, and into Mediterranean Europe from North Africa (Calistri et al., ; Lorusso et al., ; Eagles et al., ). Infected midges were likely responsible for the spread of BTV‐16 from Italy to Croatia (Listeš et al., ), from Sardinia to Corsica (BTV‐2 in 2000, BTV‐4 in 2003, BTV‐16 in 2004, BTV‐1 in 2013) and BTV‐8 from mainland Europe to the UK in 2007 (Gloster et al., ; Szmaragd et al., ).…”

A specific concept of strain was developed in order to classify the BTV serotypes ever reported in Europe based on their properties of animal health impact: the genotype, morbidity, mortality, speed of spread, period and geographical area of occurrence were considered as classification parameters. According to this methodology the strain groups identified were (i) the BTV strains belonging to serotypes BTV-1-24, (ii) some strains of serotypes BTV-16 and (iii) small ruminant-adapted strains belonging to serotypes BTV-25, -27, -30. Those strain groups were assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7, Article 5 on the eligibility of bluetongue to be listed, Article 9 for the categorisation according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species related to bluetongue. The assessment has been performed following a methodology composed of information collection, expert judgement at individual and collective level. The output is composed of the categorical answer, and for the questions where no consensus was reached, the different supporting views are reported. The strain group BTV (1-24) can be considered eligible to be listed for Union intervention as laid down in Article 5(3) of the AHL, while the strain group BTV-25-30 and BTV-16 cannot. The strain group BTV-1-24 meets the criteria as in Sections 2 and 5 of Annex IV of the AHL, for the application of the disease prevention and control rules referred to in points (b) and (e) of Article 9(1) of the AHL. The animal species that can be considered to be listed for BTV-1-24 according to Article 8(3) are several species of Bovidae, Cervidae and Camelidae as susceptible species; domestic cattle, sheep and red deer as reservoir hosts, midges insect of genus Culicoides spp. as vector species.

“…The analysis of all genome segments is crucial when a novel BT outbreak occurs in a given area, even more so when multiple serotypes circulate at the same time or when modified live vaccines have been used in the past in the outbreak area. BTV serotype 1 (BTV-1) reoccurred in Sardinia, Italy, in 2012 (3) and 2013. Unlike in 2012, in 2013, BTV-1 moved toward Corsica, Sicily, and mainland Italy.…”
