In horses, two forms of generalised steatitis have been described: one subcutaneous nodular form and one diffuse systemic form. Three cases of the second form are described in this paper. The clinical signs included depression, anorexia, diarrhoea, abdominal pain, fever, subcutaneous oedema, tachycardia and tachypnea. Blood analyses showed anemia, neutrophilia, hypoalbuminemia, increased muscular enzymes activities, and low level of vitamine E concentration. Abdominal ultrasound demonstrated an irregular hyperechoic band of peritoneal fat tissue. Ante mortem diagnosis was achieved in 2 horses, one on the basis of rectal biopsies and one on the basis of biopsies of the nuchal ligament. Despite a corticoids therapy and vitamin E supplementation, the 3 horses died or were euthanized. Those cases confirm that, in horses, diagnosis of systemic diffuse generalised steatitis is difficult and that the prognosis is poor. [less ▲]

Schmallenberg virus, a novel orthobunyavirus, is spreading among ruminants, especially sheep and cattle throughout Europe. To determine the risk for domestic dog infection, we conducted a survey among cases referred to the university Companion Animal Clinic to assess possible seroconversion. No evidence of transmission to dogs was detected. [less ▲]

Field and laboratory observations suggest that Schmallenberg virus was circulating in Belgium during the summer 2012 despite a very high herd immunity. Further studies will be conducted to determine whether we are observing the last cases of this epizootic or if the above calves announce a transition to endemicity. [less ▲]

The Schmallenberg virus emerged in summer-fall 2011 in North-West Europe. Nine months later, 91% of adult cattle living about 250 km from the emergence location tested positive for IgGs targeting the new virus nucleoprotein. Further, the risk of infection of the fetus in an immunologically naive herd is 28%. [less ▲]

In the summer-fall of 2011, a nonspecific febrile syndrome characterized by hyperthermia, drop in milk production and watery diarrhea was reported in adult dairy cows from a series of farms located in North-West Europe. Further, in November 2011, an enzootic outbreak of abortion, stillbirth and birth at term of lambs, kids and calves with neurologic signs and/or head, spine or limb malformations emerged throughout several European countries. Both syndromes were associated with the presence in the blood (adults) or in the central nervous system (newborns) of the genome of a new Shamonda-like orthobunyavirus provisionally named Schmallenberg virus after the place where the first positive samples were collected. The clinical, pathological, virological and epidemiological facts that were made publicly available during the first 6 months after the emergence are presented here. Current knowledge of the epidemiology of the phylogenetically closest relatives of the newcomer (Shamonda, Aino and Akabane viruses) is not exhaustive enough to predict whether the current outbreak of Schmallenberg virus is the prelude to endemicity or to a 2 years long outbreak before the infection burns out when serologically naïve animals are no longer available. In the future, cyclic epizootic reemergences are a possibility too, either synchronized with a global decrease of herd immunity or due to antigenic variants escaping the immunity acquired against their predecessors. The latter hypothesis seems unlikely because of the wide array of biologic constraints acting on the genome of viruses whose life cycle requires transmission by a vector, which represses genetic drift. The remarkable stability of the Shamonda virus genome over the last forty years is reassuring in this regard. [less ▲]

For several decades, the bovine was subject to various hemorrhagic syndromes which causes have historically been found. Since the mid-2000s, a new hemorrhagic syndrome seems to emerge with a significant epidemiological consistency, suggesting a common etiology, although unknown at present. The affected animals were calves of less than 30 days, of all races born to mothers without specific parity. We noticed a very sporadic disease (1/10.000) but lethal to 99%. The characteristic lesions are multifocal hemorrhages, hyperthermia, melena, we noted medullar aplasia systematically. These calves are vironegative for BTV, enzootic bovine leukosis and BVDV. No viral or bacterial agent could be isolated. It seems that most of these calves were born from dams vaccinated against BVDV. The track of an immune dysfunction is the most serious for the moment.
