Associated Data Supplementary Materials viruses-12-00096-s001.zip (264K) GUID: 77E20961-D895-4ECB-AB21-E2CC9545B311 Abstract In September 2016, clinical signs, indicative of bluetongue, were observed in sheep in Cyprus. Bluetongue virus serotype 8 (BTV-8) was detected in sheep, indicating the first incursion of this serotype into Cyprus. Following virus propagation, Nextera XT DNA libraries were sequenced on the MiSeq instrument. Based on the available sequencing data, the incursion BTV-8 into Cyprus most likely occurred from the neighbouring countries (e.g.

, Israel, Lebanon, Syria, or Jordan), where multiple BTV serotypes were co-circulating rather than from Europe (e.g., France) where a single BTV-8 serotype was dominant. The severity of BT varies between species and can cause high mortality, weight loss and disruption of wool growth in sheep, which are the most vulnerable species. In contrast, BT in cattle is usually asymptomatic but, due to the prolonged viremia, cattle play an important role in virus transmission. BT is a notifiable disease by the World Organisation for Animal Health (OIE) and suspicion of disease needs to be reported to government authorities due to its high impact on domestic ruminants. BTV belongs to the Orbivirus genus within the family Reoviridae and, as with other members of this genus, it has a linear double-stranded (ds) RNA genome consisting of 10 segments (Seg-1 to Seg-10). Since the 2000s, the global distribution of BTV has changed and several classical BTV serotypes (BTV-1, -2, -3, -4, -6, -8, -9, -11, and -16) have entered European countries leading to widespread disease and economic losses. Presently, the whole territory of Cyprus is classified as an animal movement restriction zone for these two serotypes. In 2006, BTV-8 emerged in the Netherlands and spread across Belgium, Germany, northern France and Luxemburg. After the winter season, BTV-8 re-emerged and spread to other countries such as Denmark, Switzerland, the Czech Republic and the United Kingdom in 2007. Full-genome sequence analysis indicated a high sequence similarity (99.9%) between a French BTV-8 strain isolated in 2008 and in the re-emerged French 2015 BTV-8 strain. In September 2016, BTV-8 was identified for the first time in Cyprus. The aim of this study was to identify the source of the Cypriot BTV-8 outbreak through full-genome sequencing.

The relationship between the Cypriot BTV-8 strain with historic and the most-recent BTV-8 strains circulating in Europe and neighbouring countries was investigated here by two independent approaches: phylogenetic analysis of segment-specific trees and construction of the phylogenetic network. 2. Materials and Methods 2.1. Epidemiological Investigation The first three suspected cases of BT in sheep were reported simultaneously on 19 September 2016 by the same private veterinarian in three different locations in Cyprus. Tracings confirmed that these cases were not epidemiologically linked. The observed clinical signs included fever, mouth and lip oedema (swelling), nasal discharge, lameness, abortions and increased mortality. EDTA blood samples from affected ewes were collected and sent to the National Reference Laboratory for Bluetongue virus (NRL-BTV) in Nicosia, Cyprus. The NRL-BTV confirmed the presence of BTV by serogroup-specific real-time RT-PCR on 20 September 2016. During the BTV-8 outbreak in Cyprus, the farms in Larnaca District were foremost affected and suffered economic losses. An initial epidemiological investigation showed that the clinical signs were observed between 8 and 12 September 2016, indicating that the BTV incursion probably occurred in late August 2016. BT control measures were imposed, including the establishment of surveillance and protection zones and animal movement restrictions. In addition, farmers were advised on the use of insecticides and general biosecurity measures with the aim of containing the disease. Moreover, veterinary advice and guidance on the proper supportive care for the ill animals was given in order to reduce the case fatality rate. The last case of BTV-8 was detected in the middle of December 2016. A mass vaccination campaign to vaccinate all sheep, goats and cattle commenced in February 2017 and no further cases of BTV-8 have been reported in Cyprus since. 2.2.

Clinical Manifestation Although most of the sheep showed a degree of illness, mortality occurred in pregnant ewes, ewes after lambing and newborns. Two or three of these listed symptoms were found in most of the infected sheep. In addition, an increase in abortion, stillbirth, or delivery of weak or malformed newborn lambs was recorded. Mild cases which received prompt and proper supportive treatment and care recovered rapidly and completely. However, practitioners later revealed that fertility had been impaired and that milk production had been suboptimal in sheep. In contrast, clinical signs were not observed in cattle and were rare in goats. Cattle and goats were found to harbour the virus (viraemia was confirmed by molecular testing) and animal movement restrictions were put in place. 2.3. Diagnostics and Sample Selection for Virus Isolation 2.3.1. The NRL-BTV in Nicosia, Cyprus The ID Screen Bluetongue Competition ELISA (ID VET, Montpellier, France) was used for the detection of antibodies against the BTV VP7 protein in 992 serum samples (537 sheep; 244 goats; 211 cattle) according to the manufacturer’s instructions. Table 1 BTV isolates sequenced during this study and associated Genbank accession number for the genome segments. DsRNA was purified using the RNA clean and concentrator kit (Zymo, Irvine, CA, USA) according to the manufacturer’s recommendations. Double stranded cDNA was purified using the Illustra GFX PCR DNA and Gel Band Purification kit (GE Healthcare, London, UK) and quantified with the Qubit dsDNA HS Assay kit (Life Technologies). If the consensus sequence contained any gaps, a BLAST search was performed in order to find a more suitable reference sequence. Finally, the consensus sequence was used as a reference sequence to increase the number of BTV reads mapped to the reference, and the final consensus sequence was saved and used for further analysis.

Full genome sequencing data of the BTV isolates from Cyprus and Israel were submitted to Genbank ( Table 1 ) along with the historic BTV reference strains ( Table S1 ). 2.6. Phylogenetic Analysis BTV reference sequences were retrieved from Genbank to represent all BTV genotypes that have been proposed by a BTV genome sequence data resource (BTV-GLUE, ). The BTV nomenclature proposed by BTV-GLUE was used throughout this manuscript. All phylogenetic trees were visualised and rooted on the midpoint in the MEGA6 software. NAME is a Lagrangian particle dispersion model that simulates the release, transport, mixing and removal of material in the atmosphere. NAME calculates the trajectories of a large number of model particles through the time-varying, three-dimensional wind field provided by a Numerical Weather Prediction (NWP) model, with an additional stochastic velocity component included to represent turbulent mixing processes that are unresolved by the driving NWP. The trajectory of each model particle was calculated backwards in time from its origin, and at each model timestep the trajectories that were located within the lowest 200 m of the atmosphere were aggregated onto a regular horizontal grid, of approximately 5 km spacing. The resulting trajectory densities represent the near-surface footprint of air parcels that subsequently passed over Larnaca. Source 1 covered northern Syria, Source 2 covered southern Syria and northern Lebanon, Source 3 covered central Lebanon, Source 4 covered southern Lebanon and northern Israel, Source 5 covered central Israel, and Source 6 covered southern Israel and Gaza. Simulations were initiated twice a day throughout the period 20 July to 17 September 2016, with model particles being released over the 3-h period around local sunrise and the 3-h period around local sunset, respectively, to represent the diel activity of Culicoides.

As with the air history simulations, trajectories for each midge dispersal simulation were aggregated onto a 5-km horizontal grid whenever they were within 200 m of the surface, resulting in twice-daily near-surface footprints of midge density from each potential source. Two genotypes such as BTV-8 and BTV-16B were detected in the isolates originating from Cyprus and five different genotypes (BTV-2A, BTV-5, BTV-8, BTV-12, and BTV-24) in the isolates from Israel. In addition, all sequences analysed were classified into eleven genogroups (designated from A to K) and this grouping was statistically supported ( Figure 1 a). Atypical BTV sequences were not classified with either western or eastern viruses possibly indicating their unique origin. The Neighbor-Net network shows the split between the BTV strains belonging to the western and eastern topotype in addition to the formation of separate genogroup K containing the atypical BTV strains ( Figure 2 ). Nomenclature used in-line with that proposed by the BTV-GLUE resource for the BTV Segment 2. Solid coloured lines were added manually to indicate the genogroup while the dashed blue lines were added manually to indicate the distinct differences between the western and eastern topotypes, and genogroup K which contains the atypical BTV strains. 3.4. Atmospheric Dispersion Modelling Aggregated NAME air history maps ( Figure 3 ) show that the most common origin of air that reached the Larnaca region over the period under consideration was between the west and north west of Cyprus, around the area of Crete and Rhodes. However, against this background of a dominant westerly origin of air reaching Larnaca, there is also an eastward extension of the air history towards the coastlines of Syria, Lebanon and Israel. Some of the air that reached Larnaca within 24 h had origins along the central Lebanon coastline, and potentially from coasts of northern Israel and central Syria.

Extending the timeframe to consider air that took up to 36 h to reach Larnaca, the potential area of origin can be extended to include most of the coastline of Syria and Israel. None of the 12-h air histories extended far enough east to reach any of these coastlines (not shown). Open in a separate window Figure 3 Maps of the near-surface history of air passing over the Larnaca region, aggregated over the period 21 July to 18 September 2016. Air parcels with a lifetime of ( a ) 24 h and ( b ) 36 h are shown. The NAME midge dispersal simulations are summarised as a list of potential incursions in Table 2, constructed from manual inspection of the aggregated trajectory densities from each source in each of the twice-daily simulations, examples of which are shown in Figure S2. Potential incursions with a 24-h flight time would have likely only come from between southern Syria and southern central Lebanon. It is unlikely that the source in southern Israel or Gaza was responsible for any incursions. None of the 12-h midge dispersal simulation sources had potential incursions into the Larnaca region. Table 2 Date and time of NAME midge dispersal simulations that suggested potential incursions into the Larnaca region from Syria, Lebanon or Israel. Event Date and Time 24-h Midge Sources 1 36-h Midge Sources 1 (a) 11 September 2016 SS 3 3 However, the phylogenetic trees constructed for the individual segments of BTV provide evidence of reassortment occurring in individual Segments 4, 7, 9 and 10. Since the closest relative for each of ten BTV segments originated from Israel, this provides enough evidence to rule out the importation of BTV-8 infected animals from central Europe (e.g., France) as a potential source of the BTV-8 outbreak in Cyprus. It is highly likely that the Cypriot BTV-8 strain emerged in an area where multiple BTV strains were co-circulating allowing for the exchange of segments.

Countries such as Israel, Lebanon, Syria and Jordan are considered the most likely donor of new BTV serotypes to Cyprus based on the available epidemiological data (reported circulation of BTV-8) and their proximity to the island. In contrast, no clinical signs were reported in cattle during the 2016 BTV-8 outbreak in Cyprus, indicating the possibility that the different genome constellation of BTV-8 CYP2016 affects pathogenicity in cattle. Although there are limited data on the presence of BT in Jordan and Syria, due to lack of systematic surveillance, it is likely that several BTV serotypes are also co-circulating in these countries. Unfortunately, no full-genome sequencing data of the BTV-8 Lebanon strain are available. Two routes of BT incursion into Cyprus are possible, either through importation of BTV-8 positive animals or via long-distance wind dispersion (LDWD) of Culicoides vectors. Considering that first BT cases occurred in three different locations in Cyprus that were not epidemiologically linked, the importation of BTV-8 through animal movement is less likely to have happened. Nevertheless, the “air history” simulations support the hypothesis that BTV-8 infected midges could be blown across the Mediterranean Sea from the central Lebanon coastline to the Larnaca district. Moreover, several events of potential midge incursion were identified between 1 August and 11 September 2016 using the NAME midge dispersal simulations. Due to frequent reassortment, the evolutionary history of complete BTV genomes cannot be represented by a single phylogenetic tree. The bifurcating tree assumes that, once two strains diverge, they do not interact with one another in the future. Such an assumption is incorrect for BTV as the exchange of segments between different strains occurs frequently during co-infection of the host.

To accommodate for this feature of BTV evolution, the use of a phylogenetic network was investigated to provide a simple visualisation of the epidemiological relationship between strains and display the patterns which a tree representation might overlook. Several different methods to construct the phylogenetic network from sequence alignments are available including split decomposition, Neighbor-net, parsimony split or median networks. Here, we used the Neighbor-Net distance-based method as it allows for the generation of a network comprising a hundred taxa which can be scaled up if required. Although the construction of ten individual phylogenetic trees is an accurate way to analyse the sequencing data, it is also time consuming and maybe unwieldy to present the data to non-scientific audiences during disease outbreaks. In the absence of other investigative techniques such as meteorological modelling, the use of phylogenetic networks can be used to determine the origins of BTV strains. 5. Conclusions In this study, we demonstrated that the full genome sequencing data can be successfully used in tracing the source of BT outbreaks. The phylogenetic analysis of all individual BTV segments provides more valuable genetic information than the Segment 2 sequence alone. The analysis of ten separate phylogenetic trees may be impractical to present to non-scientific audiences during BT outbreak. We demonstrated that a single phylogenetic network can be used to visualise evolutionary relationships between the whole genome sequences of different BTV strains (e.g., belonging to the same serotype).

To this aim, sheep were challenged at different time points shortly after the first vaccine injection. Twenty-four Sarda sheep were divided into four groups vaccinated two weeks before challenge (Group A), one week before challenge (Group B) and concurrently with challenge (Group C). A second vaccine was performed twenty-eight days later with respect the first vaccine administration in each experimental group. The last group consisted of six non vaccinated-infected animals (NVIA). Virological and serological examinations were performed before and after challenge up to 42 and 77 days post challenge, respectively. The results of the study show that vaccination commenced as little as two weeks before challenge (Group A) prevented viremia and RNAemia in challenged sheep altogether. Conversely, Group B was partially protected from challenge and Group C showed viraemia and RNAemia similar to NVIA. This study indicates that the first administration of inactivated vaccine performed two weeks before challenge was able to prevent viraemia. Overall, our findings may have direct consequences for the management of an unexpected BTV-8 outbreak in sheep and for the legislation on sheep trade from BTV restriction areas.

In this study, pregnant ewes (6 per group) were inoculated with either field or rescued strains of BTV-2 and BTV-8 in order to determine the ability of these viruses to cross the placental barrier. The field BTV-2 and BTV-8 strains was passaged once in Culicoides KC cells and once in mammalian cells. All virus inoculated sheep became infected and seroconverted against the different BTV strains used in this study. BTV RNA was detectable in the blood of all but two ewes for over 28 days but infectious virus could only be detected in the blood for a much shorter period. Interestingly, transplacental transmission of BTV-2 (both field and rescued strains) was demonstrated at high efficiency (6 out of 13 lambs born to BTV-2 infected ewes) while only 1 lamb of 12 born to BTV-8 infected ewes showed evidence of in utero infection. In addition, evidence for horizontal transmission of BTV-2 between ewes was observed. As expected, the parental BTV-2 and BTV-8 viruses and the viruses rescued by reverse genetics showed very similar properties to each other. This study showed, for the first time, that transplacental transmission of BTV-2, which had been minimally passaged in cell culture, can occur; hence such transmission might be more frequent than previously thought. The virus particles consist of a multi-layered protein capsid enclosing the dsRNA segments. The virus can infect a variety of ruminant hosts including cattle, sheep and goats. Initial replication of BTV in ruminants occurs within lymph nodes from where it is disseminated throughout the body. Under certain circumstances, additional routes of virus transmission can be observed.

The particular features of the European BTV-8 virus which are responsible for transplacental transmission are not known. However, this property of the virus and the subsequent birth of viremic offspring may contribute towards its ability to be maintained from one year to the next (overwintering), within Northern Europe, in the absence of an active vector population during the winter months. The primary objective of this study was to characterize the properties, in sheep, of BTV-2 and BTV-8 (field strains) alongside the rescued BTV-2 and BTV-8 viruses derived from cloned cDNA. This should also determine whether the parental viruses (grown once in Culicoides cells (KC) and once in sheep choroid plexus (CP-TERT) cells) and the rescued viruses (inevitably involving further growth of the viruses in cell culture), displayed the same growth and transmission properties. In this study, pregnant ewes were inoculated with the selected BTV at about 1 month pre-term. All the inoculated ewes became viremic and seroconverted against BTV prior to parturition. The transplacental transmission of the viruses to the lambs was analyzed in each case. Materials and methods Viruses BTV-2 wt was isolated from the spleen of an adult sheep infected during the 2001 Sardinian outbreak of bluetongue. This BTV-2 virus was isolated before the first vaccination campaign, with modified live vaccines (MLV), was initiated in 2002 (within Sardinia). The BTV-2 strain rescued by reverse genetics (termed BTV-2 rg) was derived from an Italian strain isolated from an Italian sheep infected during the Sardinian outbreak in 2000. Prior to the experiment, all animals were tested and found to be negative for anti-BTV antibodies and virus. Each ewe was confirmed by ultrasound scanning to be carrying a single foetus. Animals in the four groups were inoculated sub-cutaneously on the inside of the thigh with 1 mL, containing approx. 10 6.
