We report the first full-length genomic sequences for European bat lyssavirus type-1 (EBLV-1) and type-2 (EBLV-2). The EBLV-1 genomic sequence was derived from a virus isolated from a serotine bat in Hamburg, Germany, in 1968 and the EBLV-2 sequence was derived from a virus isolate from a human case of rabies that occurred in Scotland in 2002. A long-distance PCR strategy was used to amplify the open reading frames (ORFs), followed by standard and modified RACE (rapid amplification of cDNA ends) techniques to amplify the 3′ and 5′ ends. The lengths of each complete viral genome for EBLV-1 and EBLV-2 were 11 966 and 11 930 base pairs, respectively, and follow the standard rhabdovirus genome organization of five viral proteins. Comparison with other lyssavirus sequences demonstrates variation in degrees of homology, with the genomic termini showing a high degree of complementarity. The nucleoprotein was the most conserved, both intra- and intergenotypically, followed by the polymerase (L), matrix and

The death from rabies of a bat conservationist in Dundee last year was the first fatality since 1902 from rabies acquired in the United Kingdom. The lethal virus, isolated from brain tissue at autopsy, was not the classical rabies virus but a closely related negative stranded RNA virus, the European bat lyssavirus type 2.1 The genus lyssavirus, named after the Greek for frenzy, includes the classic rabies virus, two European bat lyssaviruses, an Australian bat lyssavirus, and the African Duvenhage virus, all of which produce a similar fatal encephalomyelitis in humans-rabies.. Rabies is mainly transmitted in saliva during a bite from an infected animal. In the United Kingdom classic rabies … ...

In the frame of active lyssavirus surveillance in bats [1], oropharyngeal swabs from 2297 German bats (sampled during May 2010 and September 2013) and 134 Danish bats (sampled during August to September 2013) were investigated, using a novel generic pan-lyssavirus real-time reverse transcriptase PCR (RT-qPCR) [2]. While all of those were previously tested negative by specific real-time RT-PCRs for the detection of European bat lyssavirus type 1 and 2 as well as Bokeloh bat lyssavirus, in total, 15 swabs from bats originating from the Northeast of Germany (12) and Central Jutland in Denmark (3) had Cq values between 33.5 and 44.6 when using the assay targeting a conserved region on the polymerase (L) gene [2].. Sequencing of those amplicons revealed nine distinct rhabdovirus-related sequences (GenBank accession numbers: KJ614421 - KJ614427, KJ873057, KJ873058) outside of the lyssavirus genus. The remaining six amplicons were identical to one of the nine sequences. Nucleotide BLAST [3] analysis ...

This algorithm is represented as a flow chart. Potential exposure to lyssaviruses from a bat (either in Australia or overseas) can be separated into one of three categories. Category 1 exposures involve touching or feeding of bats, licks on intact skin, or exposure to blood, urine or faeces. These do not require any prophylaxis if the contact history is reliable.. Category 2 and 3 exposures are both treated using the same protocol. Exposures in these categories include nibbling of uncovered skin, any scratches or abrasions with or without bleeding, single or multiple transdermal bites or scratches, contamination of mucous membrane with saliva from licks, or licks on broken skin. If a person suffering a category 2 or 3 exposure has been previously immunised*†, they should be vaccinated again after exposure; both immunocompetent and immunocompromised persons should receive 2 doses delivered intramuscularly on days 0 and 3. Human rabies immunoglobulin is not indicated. If the person is at risk of ...

The boy was bitten or scratched by a bat two months ago in north Queensland, and became ill three weeks ago.. This morning Queensland Healths chief health officer, Jeannette Young, told a media conference the boy is critically ill but is in a stable condition.. Dr Young says the boy is in a coma with encephalitis type symptoms.. This is an extraordinarily difficult and distressing time for the family and I really do ask that you take that into consideration, she said.. Dr Young says as a precaution, post-exposure drugs have been given to the family and those who have been in close contact with the boy.. Australian bat lyssavirus, which is closely related but not identical to the rabies virus, was first discovered in 1996.. It is only the third confirmed case of Australian bat Lyssavirus, with the previous two being fatal.. One was a woman who was bitten on the finger while trying to remove a flying fox from a child.. The other was an animal carer.. There is no treatment for bat lyssavirus, ...

Health officials warn people not to approach or handle injured bats and flying foxes to avoid exposure to the potentially fatal Australian Bat lyssavirus, which is closely related to the rabies virus.. So far this year, more than 400 NSW residents have been given rabies post exposure prophylaxis (PEP) following high-risk exposures to potentially infected animals. About one-quarter had been bitten or scratched by a bat in Australia, while the others had come into contact with potentially rabies-infected animals overseas.. Dr Vicky Sheppeard, Director of NSW Healths Communicable Diseases Branch, said five bats had been confirmed as having lyssavirus in NSW this year.. We are concerned that with the start of the bat birthing season people may pick up or attempt to rescue young and miscarried pups that may be on the ground, Dr Sheppeard said.. Evidence of infection in several bats this year highlights the importance of avoiding bat bites and scratches. Lyssavirus infection can result in a ...

Innate immune activation is essential to mount an effective antiviral response and to prime adaptive immunity. Although a crucial role of CD169+ cells during vesicular stomatitis virus (VSV) infections is increasingly recognized, factors regulating CD169+ cells during viral infections remain unclear. Here we show that tumor necrosis factor is produced by CD11b+ Ly6C+Ly6G+ cells following infection with VSV. The absence of TNF or TNF receptor 1 (TNFR1) resulted in reduced numbers of CD169+ cells and in reduced IFN-I production during VSV infection, with a severe disease outcome. Specifically, TNF triggered RelA translocation into the nucleus of CD169+ cells; this translocation was inhibited when paracaspase MALT-1 was absent. Consequently, MALT1 deficiency resulted in reduced VSV replication, defective innate immune activation, and severe disease development. These findings indicate that TNF mediates the maintenance of CD169+ cells and innate and adaptive immune activation during VSV ...

Our findings demonstrate an important role for PERK in VSV infection. We show that PERK-mediated eIF2α phosphorylation is induced in VSV-infected cells and that this is accompanied by an inhibition of virus replication and apoptosis. PERK also plays an essential role in UPR (31) and, as such, its activation in VSV infection initially indicated an ability of the virus to elicit a UPR. This was consistent with the notion that viruses that use the ER as an integral part of their replication strategy are likely able to induce an ER stress response (1). In fact, previous studies showed that the VSV glycoprotein (VSV-G) oligomerizes in the ER prior to its transport to the cell surface (41). Misfolded and unassembled VSV-G is retained in the ER (8), whereas the interactions of the viral protein with two chaperones, BiP and calnexin, are essential for efficient folding and for retention of partially folded G protein forms in the ER (12). Thus, an overload of VSV-G in the ER during virus replication ...

La rage, due à deux génotypes de lyssavirus différents et indépendants - European bat lyssaviruses (EBLV) type 1 et type 2 - est présente dans de nombreux pays dEurope. Linfection concerne généralement les chauve-souris qui constituent le réservoir primaire des virus, mais quelques rares infections ont été observées dans dautres espèces : martres, moutons et homme. A lexception des deux cas humains, ces infections étaient toutes dues à EBLV-1. Aucun cas dérivé de EBLV-2 na été rapporté chez les animaux terrestres. La maladie, fatale chez lhomme, a été décrite en Europe suite à une morsure par une chauve-souris. Cet article fait le point sur les cas documentés de rage par EBLV en Europe chez lhomme et les chiroptères, et sur les recommandations en matière de prévention et de traitement de la rage chez lhomme. La vaccination anti-rabique pré-exposition et le traitement post-exposition sont recommandés pour les personnes exposées professionnellement. Certains pays d

TY - JOUR. T1 - First evidence of infectious hematopoietic necrosis virus (IHNV) in the Netherlands. AU - Haenen, Olga. AU - Schuetze, H.. AU - Cieslak, M.. AU - S., Oldenburg. AU - Spierenburg, M.. AU - Roozenburg-Hengst, R.E.M.. AU - Voorbergen-Laarman, H.A.. AU - Engelsma, M.Y.. AU - Olesen, N.. PY - 2016. Y1 - 2016. N2 - In spring 2008, infectious hematopoietic necrosis virus (IHNV) was detected for the first time in the Netherlands. The virus was isolated from rainbow trout, Oncorhynchus mykiss (Walbaum), from a put-and-take fishery with angling ponds. IHNV is the causative agent of a serious fish disease, infectious hematopoietic necrosis (IHN). From 2008 to 2011, we diagnosed eight IHNV infections in rainbow trout originating from six put-and-take fisheries (symptomatic and asymptomatic fish), and four IHNV infections from three rainbow trout farms (of which two were co-infected by infectious pancreatic necrosis virus, IPNV), at water temperatures between 5 and 15 °C. At least one farm ...

Infectious haematopoietic necrosis virus (IHNV) is one of the most important viral pathogens of salmonids. In rainbow trout, IHNV isolates in the M genogroup are highly pathogenic, while U genogroup isolates are significantly less pathogenic. We show here that, at a multiplicity of infection (MOI) of 1, a representative U type strain yielded 42-fold less infectious virus than an M type strain in the rainbow trout-derived RTG-2 cell line at 24 h post-infection (p.i.). However, at an MOI of 10, there was only fivefold difference in the yield of infectious virus between the U and M strains. Quantification of extracellular viral genomic RNA suggested that the number of virus particles released from cells infected with the U strain at a MOI of 1 was 47-fold lower than from M-infected cells, but U and M virions were equally infectious by particle to infectivity ratios. At an MOI of 1, U strain...

We have tested whether immunity can be transferred from a mother fish to its fry. Rainbow trout mother fish were inoculated against infectious haematopoietic necrosis virus (IHNV) by intraperitoneal injection of a fragment of the IHNV glycoprotein spanning amino acids 31 to 310. This protein fragment was obtained by isolating the specific cDNA from Japanese IHNV strain HV7601 and expressing it in Escherichia coli. Fry from immunized and control fish were exposed to IHNV at various intervals after hatching, and their mortality monitored. Survival of the fry of immunized fish was significantly greater when exposure to virus occurred 7 days after hatching, and some immunity appeared to persist until at least 25 days after hatching.

To study the molecular basis of virulence of viral haemorrhagic septicaemia virus (VHSV), we used a cross-reactive neutralizing MAb to select MAb-resistant (MAR) mutants with reduced pathogenicity for fish. From sequence determination of the G gene of MAR mutants, attenuated laboratory variant and avirulent field strains, we identified two distant regions of the glycoprotein associated with virulence: region I (aa 135-161), homologous to the putative fusion peptide of both rabies virus (RV) and vesicular stomatitis virus (VSV), and region II (surrounding aa 431-433), homologous to RV and VSV domains controlling the conformational changes necessary for the fusion process to take place. Simultaneous mutations in both regions resulted in the most attenuated phenotype and we obtained genetic evidence that regions I and II may be structurally linked. As the MAR mutants had mutations in or near domains involved in fusion, the fusion properties of VHSV and its variants were analysed. This work allowed us to

Surveillance records of the acute RNA pathogen of Pacific salmonid fish infectious hematopoietic necrosis virus are combined for the first time to enable landscape-level ecological analyses and modeling. The study area is the freshwater ecosystems of the large Columbia River watershed in the U.S. states of Washington, Oregon, and Idaho, as well as coastal rivers in Washington and Oregon. The study period is 2000-2012, and records were contributed by all five resource management agencies that operate conservation hatcheries in the study area. Additional records from wild fish were collected from the National Wild Fish Health Survey, operated by the U.S. Fish and Wildlife Survey. After curation and normalization, the data set consists of 6766 records, representing 1146 sample sites and 15 different fish hosts. The virus was found in an average of 12.4% of records, and of these 66.2% also have viral genetic analysis available. This data set is used to conduct univariate ecological and ...

AU - Racey, Paul Adrian. AU - Fooks, A. R.. PY - 2006. Y1 - 2006. N2 - Worldwide, there are more than 1100 species of the Order Chiroptera, 45 of which are present in Europe, and 16 in the UK. Bats are reservoirs of, or can be infected by, several viral diseases, including rabies virus strains (in the Lyssavirus genus). Within this genus are bat variants that have been recorded in Europe; European bat lyssavirus 1 (EBLV-1), European bat lyssavirus 2 (EBLV-2) and, four currently unclassified isolates. Since 1977, 783 cases of EBLVs (by isolation of viral RNA) have been recorded in Europe. EBLV-1 or EBLV-2 has been identified in 12 bat species, with over 95% of EBLV-1 infections identified in Eptesicus serotinus.

Bat rabies cases in Europe are mainly attributed to two lyssaviruses, namely European Bat Lyssavirus 1 (EBLV-1) and European Bat Lyssavirus 2 (EBLV-2). Prior to the death of a bat worker in Finland in 1985, very few bat rabies cases were reported. Enhanced surveillance in the two subsequent years (1986-1987) identified 263 cases (more than a fifth of all reported cases to date). Between 1977 and 2016, 1183 cases of bat rabies were reported, with the vast majority (,97%) being attributed to EBLV-1. In contrast, there have been only 39 suspected cases of EBLV-2, of which 34 have been confirmed by virus typing and presently restricted to just two bat species; Myotis daubentonii and Myotis dasycneme ...

We found antibodies against LBV in healthy E. helvum bats in Ghana. Previous studies have suggested that healthy bats develop antibodies to other lyssavirus infections (7,10,11), which may reflect past exposure, rather than survival from clinical disease. LBV likely co-evolved with its natural megachiropteran host until a genetic stasis had been reached in which the virus-host relationship was in equilibrium. This situation would result in high seroprevalence rates after a wave of virus circulation in a colony. Nine seropositive bats (8 E. helvum, 1 E. buettikoferi) were apparently healthy pregnant females. These results support theories that lyssaviruses are endemic within specific bat populations, that they may not cause high mortality rates, that exposure rates of LBV between megachiroptera in Old World African bats are high, and that bats may breed successfully after LBV exposure (7,8). The number of high reciprocal titers against LBV (Figure 1) and the history of LBV isolation in E. helvum ...

To investigate the presence of Lagos bat virus (LBV)-specific antibodies in megachiroptera from West Africa, we conducted fluorescent antibody virus neutralization tests. Neutralizing antibodies were detected in Eidolon helvum (37%), Epomophorus gambianus (3%), and Epomops buettikoferi (33%, 2/6) from Ghana. These findings confirm the presence of LBV in West Africa ...

Little is known about the factors that drive the high levels of between-host variation in pathogen burden that are frequently observed in viral infections. Here, two factors thought to impact viral load variability, host genetic diversity and stochastic processes linked with viral entry into the host, were examined. This work was conducted with the aquatic vertebrate virus, Infectious hematopoietic necrosis virus (IHNV), in its natural host, rainbow trout. It was found that in controlled in vivo infections of IHNV, a suggestive trend of reduced between-fish viral load variation was observed in a clonal population of isogenic trout compared to a genetically diverse population of out-bred trout. However, this trend was not statistically significant for any of the four viral genotypes examined, and high levels of fish-to-fish variation persisted even in the isogenic trout population. A decrease in fish-to-fish viral load variation was also observed in virus injection challenges that bypassed...

The viral haemorrhagic septicaemia virus (VHSV) comprises 4 major genotypes and a number of subtypes with, in most cases, distinct geographical distribution. A quick and simple detection method that can discriminate the different genotypes is desirable for a quick and more efficient prevention of the spread of genotypes to new geographical CX-6258 areas. A monoclonal antibody (MAb) against VHSV genotype IVa was produced, with the aim of providing a simple method of discriminating this genotype from the other VHSV genotypes (I, II, III and IVb). Balb/c mice were injected with purified VHSV-JF00Ehil (genotype IVa) from, diseased farmed Japanese flounder. Ten hybridoma clones secreting monoclonal antibodies (MAbs) against VHSV were established. One of these, MAb VHS-10, reacted only with genotype IVa in indirect fluorescent antibody technique (IFAT) and ELISA. Using cell cultures that were transfected with each of the viral protein genes, it was shown that the MAb VHS-10 recognizes a nonlinear ...

Ease of imaging and abundance of genetic tools make the zebrafish an attractive model host to understand host-pathogen interactions. However, basic knowledge regarding the identity of genes involved in antiviral immune responses is still lagging in this species. We conducted a microarray analysis of the larval zebrafish response to two models of RNA virus infections with very different outcomes. Chikungunya virus (CHIKV) induces a rapid and protective IFN response. Infection with infectious hematopoietic necrosis virus is lethal and is associated with a delayed and inefficient IFN response. A typical signature of IFN-stimulated genes (ISGs) was observed with both viruses, but was stronger for CHIKV. We further compared the zebrafish and human ISG repertoires and made a genomic and phylogenic characterization of the main gene families. We describe a core set of well-induced ISGs conserved across vertebrates, as well as multigenic families diversified independently in each taxon. The conservation ...

In 2013, Tony Goldberg, a UW-Madison professor of epidemiology, and Kathy Toohey-Kurth, a virologist at the Wisconsin Veterinary Diagnostic Laboratory, used funding from Wisconsin Sea Grant to lead a team that created a quick and accurate test for viral hemorrhagic septicemia virus (VHSV), a deadly disease that attacks the internal organs of fish, leading to bloody and large-scale fish kills. Over the past year-again with support from Wisconsin Sea Grant--Goldberg and his research team have ventured into the rivers and streams of Wisconsin, from the Apostle Islands to Janesville and the Wisconsin-Illinois border, working with the Wisconsin Department of Natural Resources to collecting fish samples to test and track the viruss current locations and movement among fish populations ...

The virulence of selected isolants of infectious hematopoietic necrosis virus (IHNV) were differentiated and correlated with electrophoretic mobilities of virion structural proteins by sodium dodecylsulfate polyacrylamide gel electrophoresis. A type 1 electropherotype of IHNV was more virulent for kokanee salmon (Oncorhynchus nerka) and a type 2 strain more virulent for rainbow trout (Oncorhynchus mykiss). Viruses from the Columbia River basin (electropherotypes 2 and 3) were more virulent for steelhead trout (Oncorhynchus mykiss) and IHNV electropherotypes from southern Oregon and California (type 3) were most virulent for chinook salmon (Oncorhynchus tshawytscha). Microscopic pathology induced by type 1 and 3 strains of IHNV in rainbow trout was less severe and involved fewer tissues than that caused by a type 2 providing further evidence that type 2 strains are more pathogenic for rainbow trout. A fluorescent antibody test (FAT) was developed for the rapid detection of IHNV. The FAT was used ...

Viral hemorrhagic septicemia (VHS), a systemic infection of various salmonid and a few nonsalmonid fishes, is caused by a rhabdovirus designated as the viral hemorrhagic septicemia virus (Office International des Epizooties 1963). The virus infection occurs in salmonids and certain other fishes of any age and may result in significant cumulative mortality. Fish that survive may become carriers. Viral hemorrhagic septicemia has been reported under various names, of which Egtved disease and Infektiose Nierenschwellung und Leberdegeneration are the best known. The viral etiology of the disease was established by Jensen (1965), and several serotypes of the virus (also known as Egtved virus) are currently recognized. Comprehensive reviews of the disease and the virus have been published by de Kinkelin (1983), McAllister (1979), Pilcher and Fryer (1980), Roberts (1978), and Wolf (1988).

Several systems were examined for the production and delivery of recombinant vaccines for fish. C. crescentus was employed to produce a fragment of the IHNV glycoprotein. When administered by injection to 0.5 gram rainbow trout (Oncorhynchus mykiss), one of the fusion proteins (184 amino acids of the IHNV glycoprotein fused to 242 amino acids of the C-terminus of the Caulobacter crescentus) protected the fish against lethal challenge with IHNV. Attenuated strains of Yersinia ruckeri were generated using allelic exchange mutagenesis. These strains were characterized in terms of in vitro growth characteristics and invasiveness. Attenuated E. coli and Y. ruckeri were exploited to deliver plasmid DNA to fish cells in vitro; attenuated Y. ruckeri bacteria were examined in vivo as bivalent vaccine delivery vehicles, either through the expression of a fragment of the IHNV glycoprotein or by carrying a plasmid DNA vaccine encoding the complete IHNV glycoprotein. A cell wall deficient strain (11.29Δdap) ...

Megabats are the reservoirs of several viruses that can affect humans and cause disease. They can carry filoviruses, including the Ebola virus (EBOV) and Marburgvirus. Species that have tested positive for the presence of EBOV include Franquets epauletted fruit bat, the hammer-headed fruit bat, and the little collared fruit bat. Additionally, antibodies against EBOV have been found in the straw-coloured fruit bat, Gambian epauletted fruit bat, Peterss dwarf epauletted fruit bat, Veldkamps dwarf epauletted fruit bat, Leschenaults rousette, and the Egyptian fruit bat. Marburgvirus has been confirmed in one species, the Egyptian fruit bat.[113][114][115] Other megabats implicated as disease reservoirs are primarily Pteropus species. Notably, flying foxes can transmit lyssaviruses, which cause rabies. In Australia the rabies virus is not naturally present; Australian bat lyssavirus is the only lyssavirus present. Australian bat lyssavirus was first identified in 1996; it is very rarely ...

Detached leeches were tentatively identified as M. lugubris in the field and were stored in one liter bottles containing lake water. Overall, 456 leeches were removed and divided into 91 pools of ~five leeches. Leeches remained alive until returned to the laboratory, where their identity was confirmed as M. lugubris according to the accepted morphological criteria [9, 10]. Each leech was briefly immersed into absolute ethanol for surface disinfection, rinsed several times in sterile water, and then sectioned into ~100 μg pieces. Samples were homogenized using a Biomaster Stomacher (Wolf Laboratories Ltd, Pocklington, York, UK) at the high speed setting for 2 min and then diluted with Earles salt-based minimal essential medium (MEM, Invitrogen, Carlsbad, CA) to produce a 1:4 dilution (w/v) of original tissues. Homogenized leech contents were removed with a sterile transfer pipette, dispensed into a sterile 15 ml centrifuge tube, and centrifuged at 5500 rcf for 20 min in the IEC Multi RF ...

Rabies and Australian bat lyssavirus (ABLV) are acute viral encephalomyelitis caused by a lyssavirus. Animals in Australia do not have rabies link. Outside Australia, rabies occurs in dogs, cats, monkeys and foxes. ABLV does occur in Australian bats. Rabies can be transmitted from rabid bats and rabid animals to humans via a bite or scratch. Animals…

A novel lyssavirus was isolated from brains of Indian flying foxes (Pteropus medius) in Sri Lanka. Phylogenetic analysis of complete virus genome sequences, and geographic location and host species, provides strong evidence that this virus is a putative new lyssavirus species, designated as Gannoruwa bat lyssavirus.

During fish disease surveys for marine rhabdoviruses in 1993 and 1995, the cod ulcus syndrome was seen widely in all ages of cod, especially the 2 to 5+ year classes. Viral Haemorrhagic Septicaemia Virus (VHSV) was isolated from a small proportion of the lesion-positive fish and these isolates were identified by immunofluorescence or ELISA. A serendipitous observation of dermal petechiae on haddock was made. VHSV was isolated from this lesion for the first time indicating a new host species for VHSV ...

Gene knock down by the use of small interfering RNAs (siRNAs) is widely used as a method for reducing the expression of specific genes in eukaryotic cells via the RNA interference pathway. But, the effectivity of siRNA induced gene knock down in cells from fish has in several studies been questioned and the specificity seems to be a general problem in cells originating from both lower and higher vertebrates. Here we show that we are able to reduce the level of viral gene expression and replication specifically in fish cells in vitro. We do so by using 27/25-mer DsiRNAs acting as substrates for dicer for the generation of siRNAs targeting the nucleoprotein N gene of viral hemorrhagic septicemia virus (VHSV). This rhabdovirus infects salmonid fish and is responsible for large yearly losses in aquaculture production. Specificity of the DsiRNA is assured in two ways: first, by using the conventional method of testing a control DsiRNA which should not target the gene of interest. Second, by assuring ...

Viral haemorrhagic septicaemia virus (VHSV) was isolated from cultured turbot fry and broodstock samples in the Trabzon coastal area of the Black Sea, Turkey in 2004. The virus was isolated in EPC and RTG-2 cell lines and identified by immunoperoxidase test, immunofluorescence test and enzyme linked immunosorbent assay. The results of applied immunological identification tests confirmed each other. This is the first report on the isolation of VHSV from cultured turbot in Turkey ...

Despite being the initial country to register confirmed cases of Mokola and Lagos bat lyssaviruses (two very distant lyssaviruses), knowledge gaps, particularly around the molecular epidemiology of lyssaviruses, still exist in Nigeria. key event, given that one of the RABV sequences (type:entrez-nucleotide,attrs:text:MN196576″,term_id:1807903095″,term_text:MN196576″MN196576) clustered with rabies variants from neighboring Niger Republic. Furthermore, three RABVs from dogs from Anambra State clustered separately forming a novel and distinctive group. Our results exhibited that transboundary transmission of RABLVs is usually a key driver in the spread of rabies in West Africa. In order for the successful control of this zoonotic disease, a multinational stepwise surveillance and removal of rabies in Africa by Anamorelin kinase activity assay 2030 is probably the answer for regional removal. genus [3,4]. Apart from RABV, which is mainly dog-mediated through bites but also ...

N2 - Viral haemorrhagic septicaemia (VHS), caused by the novirhabdovirus VHSV, often leads to significant economic losses to European rainbow trout production. The virus isolates are divided into 4 distinct genotypes with additional subgroups including sublineage Ia, isolates of which are the main source of outbreaks in European rainbow trout farming. A significant portion of Danish rainbow trout farms have been considered endemically infected with VHSV since the first disease outbreak was observed in the 1950s. However, following a series of sanitary programs starting in 1965, VHSV has not been detected in Denmark since January 2009. ...

Bats, the second largest order of mammals worldwide, harbor specific characteristics such as sustaining flight, a special immune system, unique habits, and ecological niches. In addition, they are the natural reservoirs of a variety of emerging or re-emerging zoonotic pathogens. Rhabdoviridae is one of the most diverse families of RNA viruses, which consists of 20 ecologically diverse genera, infecting plants, mammals, birds, reptiles, and fish. To date, three bat-related genera are described, named Lyssavirus, Vesiculovirus, and Ledantevirus. However, the prevalence and the distribution of these bat-related rhabdoviruses remain largely unknown, especially in China. To fill this gap, we performed a large molecular retrospective study based on the real-time reverse transcription polymerase chain reaction (RT-qPCR) detection of lyssavirus in bat samples (1044 brain and 3532 saliva samples, from 63 different bat species) originating from 21 provinces of China during 2006–2018. None of them were

Vesiculoviruses enter cells by membrane fusion, driven by a large, low‐pH‐induced, conformational change in the fusion glycoprotein G that involves transition from a trimeric pre‐fusion toward a trimeric post‐fusion state via monomeric intermediates. Here, we present the structure of the G fusion protein at intermediate pH for two vesiculoviruses, vesicular stomatitis virus (VSV) and Chandipura virus (CHAV), which is responsible for deadly encephalopathies. First, a CHAV G crystal structure shows two intermediate conformations forming a flat dimer of heterodimers. On virions, electron microscopy (EM) and tomography reveal monomeric spikes similar to one of the crystal conformations. In solution, mass spectrometry shows dimers of G. Finally, mutations at a dimer interface, involving fusion domains associated in an antiparallel manner to form an intermolecular β‐sheet, affect G fusion properties. The location of the compensatory mutations restoring fusion activity strongly suggests that ...

BOISE, Idaho -- Federal fish managers say a potentially deadly virus has prompted them to kill tens of thousands of juvenile steelhead at the Dworshak National Fish Hatchery. Hatchery manager Larry Peltz says staff found a viral disease called Infectious Haematopoietic Necrosis that infects salmon and trout and can be fatal. The Idaho Statesman reports the fish were killed on Tuesday to reduce the threat of the disease spreading to other holding ponds at the hatchery. ...

Bats are the ancestral reservoir of lyssaviruses including RABV and a remarkable diversity of species perpetuate distinct lyssavirus lineages across the world (see Classification). Unfortunately, much less is known regarding transmission of lyssaviruses in bat reservoirs (see Bats and Conservation). Sympatric bat species may contribute to lyssavirus circulation within one or more reservoir hosts.

Annual Review Of Entomology. 54:447-468. Interpretive Summary: Technical Abstract: The rhabdoviruses form a large family (Rhabdoviridae) whose host ranges include humans, other vertebrates, invertebrates, and plants. There are about 75 plant-infecting rhabdoviruses described, several of which are economically important pathogens that are persistently transmitted to their plant hosts only by insect vectors, particularly aphids, leafhoppers and planthoppers. Additionally, many vertebrate-infecting rhabdoviruses are biologically transmitted by hematophagous insects. Rhabdoviruses replicate in their insect hosts, and each virus is normally transmitted only by one or a few related vector species. In this review, we provide an overview of propagative transmission of plant rhabdoviruses, as compared to ...

These strains can be classified in three groups the European strains, the American strains plus the African buffalo strains. It is estimated that the taurine and buffalo strains diverged about 730,000 years in the past and the Eur opean and North American clades diverged all-around 260,000 many years in the past. The genome with the BoHV four 66 p 347 North American strain has totally been sequenced. Nevertheless, the BAC cloned reference strain V. check belongs for the European clade. Past stu dies advised the BoHV four V test strain is made up of regions of high dissimilarity in contrast to your BoHV 4 66 p 347 strain. Without a doubt, the nucleotide identity involving the two strains continues to be previously measured for being as very low as 88% to the BORFB2 region. Having said that, the lack of a total genomic sequence for that V.. check strain prevents from drawing a standard see regarding this divergence level. Thus, the very low excellent of the genomic informa tion hampers the use of ...
