Schmallenbergvirus widespread along the coast of southern Norway

Published: 11/27/2012

Examination of milk samples for Scmallenbervirus shows that many herds in southern Norway have been infected by the virus.

Fisheries and Veterinary Institute has conducted a survey of bulk milk samples for antibodies against Schmallenbergvirus from herds in southern Norway. By ca. 2400 herds that have been examined have more than 400 herds antibodies against the virus, most infected situated along the coast and rivers. There are large regional differences regarding the proportion of positive herds, with more than 50% positive in the counties of Østfold, Vestfold, Aust-Agder, while it is less than 2% positive herds in Rogaland.

Schmallenbergvirus transmitted by biting midges and can infect cattle, sheep, goats and wild ruminants and cause serious birth defects when infection in the first half of gestation. Surveys in Europe in 2011 and 2012 has proven Schmallenbergvirus approx. 4% bovine herd and about 7% of sheep farms.

FSA monitors the situation and follow up with further studies in 2013.

New virus in sheep and cattle in Sweden

For the first time, the proliferation of Schmallenbergvirus confirmed in Sweden and studies show that the infection is widespread in the country.

Viruses have also been demonstrated in the midges that spread the disease. Infection with the virus can lead to malformed fetuses in sheep, goats and cattle. The infection will not lead to any restrictions imposed by the Board of Agriculture and the keepers will be able to move their animals as usual.

In late 2011 found a new virus in ruminants in Germany, Holland and Belgium. In 2012 it spread to many more countries in Europe. The virus is named after the place where it was first discovered, Schmallenberg. The virus does not spread to humans and it is not dangerous to drink milk or eat meat from animals that have had the infection. Agriculture and the National Veterinary Institute (SVA) has conducted a national survey of cow's milk from many farms investigated because antibodies to the virus is excreted in the milk . A large proportion of the samples indicates that there are antibodies. SVA also demonstrated virus in samples from three midges, the insect that spreads the disease. - In view of the reports of contamination levels we have received from the neighboring countries in recent times, the results are not unexpected. Since the infection is spread by midges, no contamination during the winter, says Erika Chenais, epidemiologist at SVA.

The pregnancy of ruminants affected by the virus

The virus has affected pregnancy in ruminants in Sweden suspected of including in a sheep herd in south-eastern Sweden. Several of the animals that did not become pregnant also had antibodies to the virus. This implies a relationship but is no definitive evidence that virus infection has caused the symptoms, which may also have other causes. Earlier this year found evidence of infection in Sweden last autumn, but it is not until now has anyone seen a proliferation and possible links between the infection and the symptoms of ruminants in the country. A major outbreak involving cattle and sheep in early pregnancy can cause serious production losses.

SBV all over France

Emerging Infectious Disease Journal

Acute Schmallenberg Virus Infections, France, 2012

To the Editor: After unexpected emergence of bluetongue virus serotype 8 in northern Europe in 2006 (1), another arbovirus, Schmallenberg virus (SBV), which is transmitted by Culicoides spp. biting midges, emerged in Europe in 2011 and caused disease outbreaks among ruminants (2). Nonspecific clinical signs such as fever, decreased milk production, and diarrhea were associated with acute infection in cattle, and late abortions and birth defects in newborns were associated with infection of pregnant cows, ewes, and goats (2,3).

SBV, which belongs to the family Bunyaviridae and genus Orthobunyavirus, was detected in Germany, the Netherlands, and Belgium in 2011. This virus was later detected in the United Kingdom, France, Italy, Luxembourg, Spain, Denmark, and Switzerland (4). As of August 1, 2012, a total of 5,701 infected farms were reported in Europe (2,498 sheep farms, 3,124 cattle farms, and 79 goats farms) (www.survepi.org/cerepi/). France has been the country most affected: it had 2,650 SBV-infected farms (5), (i.e., in which >1 malformed offspring was positive for SBV by real-time reverse transcription PCR [RT-PCR] on 1,128 sheep farms, 1,505 cattle farms, and 17 goat farms).
Abnormalities detected in offspring in 2011 and in early 2012 were caused by infections acquired in 2011 (4). At that time, it was unclear whether SBV could survive the 2011–2012 winter and remain a threat to Europe. We report data suggesting that SBV overwintered or was reintroduced in France.
Figure

On May 16, 2012, a herd of 75 dairy cows in southwestern France (Pyrénées-Atlantiques) had hyperthermia and decreased milk production. Of 18 cows tested by the Agence Nationale de Sécurité Sanitaire (Maisons-Alfort, France), 9 were positive for SBV by PCR (6) (cycle threshold [Ct] range 17–36.5) and negative for SBV by ELISA (IDVet, Montpellier, France), 1 was positive by PCR and ELISA, and 8 were negative by PCR and ELISA (Figure).

On May 23, a week after the first samples were collected, all cows tested were positive by ELISA and only 1/18 cows were positive by RT-PCR. On June 29, all 18 cows tested were negative by RT-PCR. Detection of SBV-neutralizing antibodies by virus neutralization assay in serum samples obtained on May 23 confirmed SBV ELISA results and showed that a commercial IgG ELISA is suitable for detection of acute cases of SBV.

Viremia, as measured by RT-PCR, occurs during the first 5 days after acute infection (2). Antibody response against SBV, as measured by ELISA, is detected during or after the first 10 days after experimental infection (C. Sailleau et al., unpub. data). Accordingly, serologic and molecular data showed that acute SBV infection occurred in cattle in southwestern France in May 2012, suggesting that SBV overwintered or was reintroduced.

Moreover, in July 2012, another case of acute SBV infection was identified in Finistère (Brittany). A cow with hyperthermia and diarrhea was SBV positive by RT-PCR (Ct 31) and negative by ELISA, which indicated a recent SBV infection.

Three blood samples (each 170 µL) from RT-PCR–positive cows (Ct range 15–21) (1 from the Finistère and 2 from Pyrénées-Atlantiques) were injected into 3 adult IFNAR−/− mice. Seventy microliters of each sample was injected intraperitoneally and 100 μL was injected into the neck scruff of the same mice. After 4 days, the mice showed no clinical signs and their weights were unchanged. Blood samples were collected and tested for SBV by RT-PCR. All mice were positive for SBV RNA (Ct range 15–21). These data showed that blood samples from cows contained virus RNA and confirmed that SBV reemerged in 2012.

On July 25, 2012, SBV infection was identified in a cow in Jura Canton in the northwestern, French-speaking region of Switzerland (Romandie) (7). A serologic study conducted in the United Kingdom showed that several cattle and sheep seroconverted for SBV in 2012 (8). However, our data show that SBV survived the winter, when midge numbers decreased. The precise mechanisms of SBV overwintering are not known and need to be explored.

The consequences of SBV recirculation should be investigated, particularly in pregnant cows, ewes, and goats. The 2 SBV-positive farms described in this report are located in a previously SBV-free area (Finistère-Brittany) or an area in which the infection rate was low (Pyrénées-Atlantiques) in the winter of 2011–2012, during which seroprevalence for most herds was probably weak (C. Sailleau et al., unpub. data). Therefore, reemergence of cases of congenital forms of SBV infection in France and others areas of Europe can be expected.

Norway: antibodies to Schmallenberg virus detected in milk

Published: 11/14/2012

The Veterinary Institute found antibodies against Schmallenberg virus in milk samples from cattle herds in eastern Norway. Detection of antibodies means that the animal has been infected by the virus at one time or another. Schmallenberg virus is not contagious to humans. It is not dangerous to drink milk or eat meat from animals that are infected.

25. October this year, the National Veterinary Institute that Schmallenberg virus was detected in Norway for the first time. The virus was found in biting midges. When biting midges sucking blood from infected animals can transmit the virus to other animals they suck blood from. The virus can cause brief illness in cattle and sheep. Animals that are infected early in pregnancy may have babies that are stillborn or who have severe deformities.

Not dangerous to drink milk or eat meat

Now, antibodies against the virus detected in samples of milk from Norway. The samples are examined as part of a monitoring program that FSA and Veterinary Institute collaborate. It is not dangerous to drink milk or eat meat from animals in the herds milk comes from ..

Mapping the extent

Schmallenberg is not considered a dangerous disease, but may have implications for those engaged in livestock. Veterinary Institute and the FSA are now working to examine milk from throughout southern Norway to get a picture of the spread. Currently there are 532 milk samples examined, and of these 72 samples were positive. Veterinary Institute, believes the results from the remaining 1700 samples have been received will be ready within the next week. FSA is now underway to probe into some of the herds who delivered milk that contains antibodies against the virus.

Mystery surrounds calf and lamb losses

Rhian Price

Friday 16 November 2012

Mystery surrounds pregnancy scanning results, which show potentially devastating numbers of calf and lamb losses on UK farms.

Livestock producers face early lambing losses as high as two-thirds on some farms, suggest initial results. Many scanners are reporting barren ewes, failed pregnancies or dead foetuses. Cattle losses are almost as bad in some places.

There is a "strong suspicion" that the Schmallenberg virus could be to blame, say some vets. But other causes, such as poor nutrition following a year of extreme wet weather, have been cited by other vets and animal health experts.

John Barnes, a scanner in the north east of England, told Farmers Weekly he had recorded problems in about two-thirds of 10,000 ewes across 80 flocks. One farm later tested positive with the Schmallenberg virus, which can cause death and deformity in unborn livestock.

Cattle scans revealed up to 50% of 4,000 cows scanned were showing either empty or with dead calves.


Other operators have begun to report similar problems as scanning gets into full swing ahead of next spring's lambing season.

In the West Midlands, scanner Phil Preece reported anomalies in about a third of 8,000 early lambing ewes examined so far this year. Mr Preece said it was a "real one-off" and he had not experienced results like it in 14 years of scanning.

Both men said they had spoken to other scanners who reported similar issues.

It is not known if these cases are linked to the Schmallenberg virus, but flocks at highest risk from the virus would have been those tupped in late summer or early autumn when midge activity was at its highest.

Ireland: second case of livestock virus found

ALISON HEALY

A second case of a newly discovered livestock disease has been confirmed.

The first Schmallenberg virus case was confirmed by the Department of Agriculture last week following tests on a bovine foetus which came from a farm in Co Cork. This latest case was discovered on another Cork farm. A cow had aborted a foetus and a postmortem confirmed the presence of the virus.

The Schmallenberg virus does not pose a risk to human health or have food safety implications, but if cows, sheep or goats come in contact with the virus during the early stages of pregnancy, they may subsequently abort or give birth to malformed offspring.

The disease is thought to be spread by midges.
