Virus Schmallenberg

Depuis le 1er décembre, de nombreux cas de mortinatalité et de malformation chez des agneaux (mort-nés avec cou tordu, hydrocéphalie, membres déformés,…) ont été enregistrés aux Pays-Bas et Allemagne. Quelques veaux présentant des symptômes similaires ont également été signalés.

Finalement le 23 décembre, le premier cas en Belgique a été détecté sur des agneaux nouveau-né présentant des malformations et/ou mort-né.

Jusqu'aujourd'hui le virus Schmallenberg a été révélé dans 95 exploitations ovines, 7 exploitations bovines, et 1 exploitation caprines. Il est attendu que d’autre cas vont être mis en évidence et ce notamment dans la mesure où la période de gestation, principalement chez les ovins et les caprins, va prochainement débuter.


Exploitations où le virus a été mis en évidence:

Exploitations bovines - 7

Exploitations ovines - 95

Exploitations caprines - 1

From the excellent and frequently updated website Warmwell, by Mary Critchley

February 10th 2012 ~ Reactions of the virologist, Ruth Watkins, after the online discussions

Dr Ruth Watkins, formerly Head of Diagnostic Virology at St Mary's Hospital where she was an Honorary Consultant and Senior Lecturer in the Department of Virology at St Mary's Hospital Medical School, Imperial College School of Medicine, London, is currently a sheep farmer in Wales. With her expertise in virology and first hand knowledge of farming, her views are very valuable. Her summary of points:

All those farms on which there has been an outbreak should keep those ewes to breed next year. From experience with Akabane and the use of vaccines it is clear that immunity from the acute and short lasting infection in the adult ewe is strong and likely to provide protection against reinfection. I am not sure if sufficient ewe lambs from this summer will also have been infected on these farms but this may well be so. So these ewe lambs as yearlings put to the ram next year if infected in 2011 or early in the summer of 2012 should not have affected lambs as they will be protected against having the infection whilst pregnant.

The concept of the susceptible period of the foetus during which a primary infection of the mother ewe will cause death or deformities was not mentioned. It should be.The farmer with her question about lambing ewes in May should have no cause for concern. Even if infected in May there should not be a problem with her lambs. (There is a possibility of meningo-encaphalitis in calves and cattle but we don't know if this will occur with Schmallenberg virus and it only seems to occur with certain strains of the Shamondo viruses, and no comment can be made on this yet. I don't think there is a need to mention it).

It is clear that lambing in April May would be advisable next year. May would be preferable. It was very mild this year and I am not sure when midges were no longer active but they could certainly have been through November at least. I believe that Pirbirght should be able to answer this. This would mean putting rams in at the start of December. This is such an important point that I am surprised the BVA man has not grasped it. I put my rams in in November but I am going to wait until December next year if the Schmallenberg virus is shown to be active next summer in the UK.

The best date for cattle pregnancies is going to be a problem. The period of susceptibility of calves in utero is longer than for sheep. Also dairying and so on require Spring and Autumn calving. Probably Autumn calving will be safer than Spring calving.

There should have been absolute clarity in the answer that no product has been shown to repel midges sufficiently to prevent biting and infection. Again the BVA vet should have been absolutely clear on this- he was corrected by the Belgian farmer. (Where was he during the BTV8 outbreak?)

Re: Schmallenbergvirus : new Akabane-like virus in cattle, sheep and goats in Europe

Cows infected after eating from infected afterbirth?

In an article from 2008 about "bluetongue", a number of possibilities are mentioned, how the virus can survive wintertime.

A researcher says:

There is also circumstantial evidence that cattle could become infected orally if they eat the afterbirth of an infected offspring from another cow.

http://www.sciencedaily.com/releases/2008/08/080825203916.htm

Eating from an afterbirth is normal, natural behavior of cows.

May be something to take into account , in relation to "Schmallenberg".

Re: Schmallenbergvirus : new Akabane-like virus in cattle, sheep and goats in Europe

Note: at this moment it is hard to confirm "Schmallenberg" in cattle. In a few weeks a serological test will be available. Than we can know the true extent of the spread of Schmallenberg.

In the Netherlands malformed calves outnumber malformed lambs.


From DEFRA

Schmallenberg virus: updated 14 february 2012

Schmallenberg virus (SBV) has now been identified in samples submitted from 40 farms in the south and east of England, across the counties of Norfolk, Suffolk, Essex, Kent, East Sussex, West Sussex and Hertfordshire.

All of the counties where SBV infection has been identified are in the zones recognised as potentially at risk from infected midges being blown across last summer from affected areas in northern mainland Europe.

With the exception of one SBV positive cattle sample from a farm in West Sussex, all of the GB cases of SBV infection have been diagnosed in sheep to date.

Figures correct as at 13 February 2012

County Submissions with confirm infection
(based on clinical signs and virus identification)

Norfolk - 10

Suffolk - 11

Essex - 3

Kent - 6

East Sussex - 6

Hertfordshire - 1

West Sussex - Sheep(2) - Cattle (1)

Schmallenberg virus

Information for farmers and vets in Great Britain

Excerpt:

Risk to humans

According to an initial risk assessment carried out by public
health authorities in the Netherlands and a follow-up risk
assessment by the European Centre for Disease Prevention and
Control, there is unlikely to be a risk to human health from
Schmallenberg virus; but this is not yet certain.

Farmers and veterinary surgeons are advised to take sensible
hygiene precautions when working with livestock and abortion
material. Although several members of the group of related
viruses can affect humans, the ability to do so is thought to be due
to a gene sequence which is not present in Schmallenberg virus.

Pregnant women should not have contact with sheep and goats
at lambing/kidding time due to risks of exposure to other
disease causing organisms.
