DBA/2J and C57BL/6J represent two opposite ends in terms of sensitivity and resistance to influenza A virus between the Mx-negative mouse lines. Several research teams focused on the factors explaining this difference, mainly by genetic approaches using Recombinant Inbred Lines between those two strains. Several candidate-genes have been proposed, but it was not possible to determine their importance. To help to define the factors involved in the susceptibility of DBA/2J mice to influenza infection, we adopted a phenotypic approach to identify the critical steps of the infection process accounting for this extreme susceptibility. Overall, the data presented here support the role of a dysfunction of alveolar macrophages, to influenza infection in the higher susceptibility of DBA/2J mice to this virus. [less ▲]

During the last decades, metagenomic studies expanded the numbers of newly described, often unclassified, viruses within the Circoviridae family. Using broad-spectrum circo-/cyclovirus PCRs, we characterized a novel circo-like virus in Aedes vexans mosquitoes from Germany whose main putative open reading frames (ORFs) shared very low amino acid identity with those of previously characterized circo-/cycloviruses. Phylogenetic and genetic distance analysis revealed that this new virus species defines, with previously described mosquito- and bat feces-derived circo-like viruses, a different genus, tentatively called "krikovirus", within Circoviridae. We further demonstrated that viruses of the putative krikovirus genus all share a genomic organization which is unique among Circoviridae. Further investigations are needed to determine the host range, tissue tropism and transmission route(s). This report increases the current knowledge of the genetic diversity and evolution of the members of the Circoviridae family. [less ▲]

Non-suppurative encephalitis and mild degeneration and necrosis were identified in the brain and cerebellum, and Usutu virus antigen and RNA were detected by immunohistochemistry and real-time reverse transcriptase PCR, respectively. The two cases reported here represent the most western distribution of clinical disease in birds due to Usutu virus. [less ▲]

Schmallenberg virus (SBV) is a recently discovered vector-borne Orthobunyavirus targeting ruminants. It is transmitted by Culicoides biting midges and caused a large outbreak in European sheep and cattle populations in 2011 and 2012. The infection of adults was associated with a drop in milk production, fever and diarrhea. But the virus was further shown to cross the placental barrier and to be responsible for a hydrocephaly/arthrogryposis syndrome in calves and lambs. After its occurrence in 2011 in Germany, SBV quickly spread across Europe and in spring 2012 more than 90% of Belgian domestic cattle had seroconverted. To assess the susceptibility of wild ruminants to the infection, a total number of 547 and 494 sera, from red (Cervus elaphus) and roe deer (Capreolus capreolus), respectively, were collected during the hunting seasons 2010 to 2012 and tested for the presence of anti-SBV antibodies. While no samples from 2010 revealed to be positive, about two-thirds of red deer and half of roe deer sampled in 2011 were seropositive. In 2012, the seroprevalence dropped to 33% in red deer and remained stable in roe deer. The high seroprevalence rates found in both species in Belgium shows that wild ruminants are susceptible to the infection by SBV. If the infection of deer was associated to a hydrocephaly/arthrogryposis syndrome similar to that observed in domestic ruminants is still unknown. There is currently no evidence of such a transplacental passage in red or roe deer. The decrease in the seroprevalence observed in red deer in 2012 might be the result of the turn-over in the red deer population and reflect an absence of virus circulation in 2012. Further investigations in the upcoming years will help to enlighten this point. [less ▲]

In the summer/fall of 2011, a nonspecific febrile syndrome characterized by hyperthermia and drop in milk production with occasional reports of watery diarrhea and abortion was reported among dairy cows on farms in northwestern Europe. Further, in November 2011, an enzootic outbreak of malformed neonates emerged in several European countries, with stillbirth and birth at term of lambs, kids and calves with neurological signs or malformations of the head, spine, or limbs. Both syndromes were associated with the presence in the blood (adults) or in the central nervous system (newborns) of a new Shamonda/Sathuperi-like orthobunyavirus, provisionally named Schmallenberg virus (SBV) after the town in Germany where the first positive clinical samples were identified. Defining as precisely as possible the host range of the newcomer is a key point to predict the outcome of the emergence of SBV disease in Europe. In this respect, it must be pointed out that orthobunyaviruses infect more animal species than those in which the foetus is damaged. Recently, serological evidence for SBV infection in wild ruminant species (Cervus elaphus and Capreolus capreolus) was reported (Linden et al., 2012). In the present study, the objective was to seek after serological evidence of SBV infection among wild boars living in a geographical area where exposure to infected insect vectors was high in 2011, as judged from the very high seroprevalence reported among cattle in that region. About 700 animals were sampled during the 2010-2012 hunting seasons. All serum samples collected during the fall of 2010 were seronegative. On the contrary, apparent seroprevalence among wild boars in 2011 was ~27% and started to decline in 2012 (~11%). Acquired immunity against the new virus was thus already very high in the wild boar populations sampled in the fall 2011, suggesting that the new virus had quickly spread throughout the region since its emergence about 250 km northeast in the late summer 2011. The drop in seroprevalence recorded in 2012 suggests that the virus was no more circulating in the region. [less ▲]

Bluetongue virus serotype 8 (BTV-8) was responsible for a large outbreak among European ruminant populations in 2006-2009. In spring 2008, a massive vaccination campaign was undertaken, leading to the progressive disappearance of the virus. During surveillance programmes in Western Europe in 2010-2011, a low but significant number of animals were found weakly positive using BTV-specific real-time RT-PCR, raising questions about a possible low level of virus circulation. An interference of the BTV-8 inactivated vaccine on the result of the real-time RT-PCR was also hypothesized. Several studies specifically addressed the potential association between a recent vaccination and BTV-8 RNA detection in the blood of sheep. Results were contradictory and cattles were not investigated. To enlighten this point, a large study was performed to determine the risks of detection of bluetongue vaccine-associated RNA in the blood and spleen of cattle using real-time RT-PCR. Overall, the results presented clearly demonstrate that vaccine viral RNA can reach the blood circulation in sufficient amounts to be detected by real-time RT-PCR in cattle. This BTV-8 vaccine RNA carriage appears as short lasting. [less ▲]

Objectives Murine norovirus (MuNoV) belongs to the family Caliciviridae, genus Norovirus and is currently used as study model for human noroviruses, major aetiologic agents of gastroenteritis worldwide. Myxovirus (Mx) protein is an interferon-induced protein that host cell can oppose virus infection and was detected in several species including human being. In mice, two genes encoding Mx1 and 2 proteins are present but it was evidenced that these genes were inactivated by deletions in several laboratory mouse strains. Mx antiviral activity was detected on several negative stranded RNA viruses but information are still lacking for most of positive stranded RNA viruses. In this study, the susceptibility of the MuNoV to specific and interspecific Mx proteins was investigated. Methods RAW264.7 cells (murine macrophages) were first tested for constitutive expression of Mx1 proteins. Plasmids containing the murine Mx1, bovine Mx1 and human MxA genes under the CMV immediate early promotor were then used to transfect RAW264.7 cells for transient Mx expression. Negative control consisted in a plasmid expressing eGFP. Four hours after transfection, cells were infected at low MOI with the CW1 MuNoV strain. Cells and supernatants were harvested 24h post infection. RNA was extracted and viral genomic copies were measured by real time RT-PCR. Results An effect was confirmed on CW1 replication for both specific and interspecific Mx proteins. The highest effect was obtained with the bovine Mx1 protein. Conclusion In conclusion, we showed in these preliminary in vitro studies the MuNoV susceptibility to specific and interspecific Mx proteins. Bovine Mx1 protein was already demonstrated to have important antiviral activity on negative stranded RNA viruses (influenza- and paramyxoviruses) and co-evolution with the host could explain a higher susceptibility to interspecific Mx proteins. Important implications of this adaptation could be expected on zoonotic concerns associated to NoV. Moreover, even if several control studies are still be conducted to validate these preliminary results, they could drive several pertaining questions on the MuNoV model used with laboratory mice. Perspectives of this work consist to validate the susceptibility in vivo and also to test the murine Mx2 antiviral activity on MuNoV. [less ▲]
