| structure of the nucleocapsid protein gene of sonchus yellow net virus. | the structure of the gene adjacent to the "leader rna" gene of sonchus yellow net virus (synv), a plant rhabdovirus, was deduced by dideoxyribonucleotide sequence analysis of synv genomic (g) rna and a series of plasmids constructed from synv grna or polyadenylated [poly(a)+] rna from synv-infected plants. evidence that this gene encodes the nucleocapsid (n) protein was obtained by reaction of synv n protein with polyclonal antibodies raised against recombinant proteins derived from the cloned g ... | 1987 | 18644572 |
| active monitoring of eblv infection in natural colonies of the mouse-eared bat (myotis myotis). | bats are important reservoir hosts of rna viruses, including lyssaviruses, which can cross the species barrier to infect humans and other domestic and wild non-flying mammals. six of the seven lyssavirus genotypes described to date infect bats. in europe, two genotypes of lyssavirus, european bat lyssavirus types 1 and 2 (eblv-1 and eblv-2), circulate among several bat species and numerous bats are found infected every year. to provide epidemiologists and public health officials with data to eff ... | 2008 | 18634518 |
| use of rabies virus as a transneuronal tracer of neuronal connections: implications for the understanding of rabies pathogenesis. | in neurosciences, rabies virus (cvs strain) has become a very powerful tool for studying multisynaptic neuronal connections, due to its ability to function as a self-replicating marker and to propagate exclusively between connected neurons by transneuronal transfer, which is strictly time-dependent. in this laboratory, transneuronal tracing studies of rabies virus propagation in primates and rodent models during the asymptomatic period have provided valuable information on rabies pathogenesis. w ... | 2008 | 18634512 |
| genetically engineered colorimetric single-chain antibody fusion protein for rapid diagnosis of rabies virus. | the most widely used test for rabies diagnostics is the fluorescent antibody test, which is recommended by both the world health organization and the world organisation for animal health (oie). this test may be used directly on a smear, and can also be used to confirm the presence of rabies antigen in cell culture or in brain tissue for diagnosis. the colorimetric enzymes are usually coupled to an antibody by chemical means using cross-linking reagents. however, such non-specific procedures lead ... | 2008 | 18634511 |
| development of an edible rabies vaccine in maize using the vnukovo strain. | the objective of this study was to obtain transgenic maize expressing the rabies virus glycoprotein (g) of the vnukovo strain and to evaluate its immunogenicity in mice, by the oral route. the ubiquitin maize promoter fused to the whole coding region of the rabies virus g gene, and a constitutive promoter from cauliflowermosaic virus (camv)were used. maize embryogenic callus were transformed with the above construct by biolistics. regenerated maize plants were recovered and grown in a greenhouse ... | 2008 | 18634510 |
| canine adenovirus based rabies vaccines. | adenovirus based vectors are very attractive candidates for vaccination purposes as they induce in mammalian hosts potent humoral, mucosal and cellular immune responses to antigens encoded by the inserted genes. we have generated e1-deleted and replication-competent recombinant canine type-2 adenoviruses expressing the rabies virus glycoprotein (g). the effectiveness of both vectors to express a native g protein has been characterized in vitro in permissive cell lines. we compared the humoral an ... | 2008 | 18634509 |
| immunogenicity of the era g 333 rabies virus strain in foxes and raccoon dogs. | the immunogenic properties of era g 333 attenuated rabies virus strain in foxes and raccoon dogs by the oral route of administration were examined. this strain is a proposed candidate for oral rabies vaccine in russia. as was previously demonstrated, the advantage of this virus, provided by the us centers for disease control and prevention in the framework of the biotechnology engagement program, is apathogenicity for 3-week old and adult mice, as well as for other target and non-target species, ... | 2008 | 18634508 |
| intake and stability of a rabies vaccine. | the intake and stability of rabies vaccine baits were studied over a two week period under field conditions. high intake of vaccine baits was observed in the spring and autumn. in the spring, the intake of vaccine baits lasted almost two weeks while in the autumn vaccine baits were consumed over the first days following distribution. differences in bait stability were observed after exposure to ambient temperatures. baits were more stable in a forest environment than on the edge of a forest. def ... | 2008 | 18634507 |
| factors influencing the antibody response to vaccination against rabies. | preventive vaccination against rabies virus is a highly effective method for preventing rabies in humans and animals. for travel purposes, vaccination of domestic carnivores is obligatory. in addition, some countries require testing for neutralizing antibodies against rabies. the minimal threshold level accepted by who/oie is 0.5 iu/ml. despite proper vaccination some animals do not reach the threshold. the objective of this study was to identify specific risk factors in dogs and cats for post-v ... | 2008 | 18634505 |
| bhk-21 cell culture rabies vaccine: immunogenicity of a candidate vaccine for humans. | veterinary rabies vaccines produced in bhk-21/c13 permanent cell cultures have been used for a long period of time and have been proven as efficacious and safe. a candidate vaccine for human use (yu bhk rabivak) was developed at the pasteur institute, novi sad, serbia on the basis of the fixed rabies virus strain "l. pasteur 2061/vero 15 pas" using bhk 21/c13 as a cell substrate for vaccine production. to test the vaccine immunogenicity, a clinical trial was conducted involving 164 subjects betw ... | 2008 | 18634504 |
| immune evasion, a critical strategy for rabies virus. | it is intriguing to note that rabv progression is interrupted neither by destruction of the infected neuron nor by the immune response. thus, it is likely that rabv has developed a subversive strategy to avoid functional neuron impairment, which compromises the infectious cycle. rabies virus neuroinvasiveness results from two factors: not only does neurotropic rabies virus avoid inducing neuronal cell death, but also 'protective' t cells that migrate into the infected nervous system are killed b ... | 2008 | 18634503 |
| one or three intradermal injections within one week for rabies pre-exposure immunization. | pre-exposure rabies vaccination is recommended fortravellers to endemic countries and forselected populations in highly endemic regions. it consists of three injections administered over 3-4 weeks. travellers often ignore or do not have enough time to receive a complete course prior to departure or leave with only one or two injections. in this study, the secondary antibody response in volunteers who received one or three injections within one week is evaluated. results are compared to the recom ... | 2008 | 18634501 |
| human rabies therapy: lessons learned from experimental studies in mouse models. | ketamine was one of the therapeutic agents used as a therapy for a human rabies survivor who did not receive rabies vaccine. ketamine therapy is re-examined here in infected mouse primary neuron cultures and in adult icr mice using the cvs strain with both intracerebral and peripheral routes of inoculation with ketamine vs. vehicle given intraperitoneally. no significant beneficial therapeutic effects of ketamine in the cultures or mouse model were observed. this team does not recommend further ... | 2008 | 18634499 |
| generalised cranial artery spasm in human rabies. | in 2004, a teenager survived bat-associated rabies through the milwaukee protocol (mp). this survivor and another patient with dog-associated rabies were found to have developed deficiencies of tetrahydrobiopterin (bh4) and associated neurotransmitters. bh4 is also essential for neuronal nitric oxide synthase (nnos), so rabies is predicted to cause constriction of cerebral arteries. we assume that rabies virus, which almost exclusively targets neurons, would disproportionately affect cerebral ov ... | 2008 | 18634498 |
| experimental infection of foxes with european bat lyssaviruses type-1 and -2. | experimental studies have been undertaken to assess the susceptibility of silver foxes to bat variants of rabies virus, namely european bat lyssaviruses (eblvs). both eblv-1 and eblv-2 have been isolated in european bats since 1954, in eptesicus serotinus and myotis species, respectively. since 2000, the number of reported cases has increased largely due to the improvement of the surveillance of bat rabies virus throughout europe. although over >800 eblvs cases have been reported in bats in euro ... | 2008 | 18634496 |
| epidemiology and pathogenicity of african bat lyssaviruses. | lyssaviruses belonging to all four known african lyssavirus genotypes (gts) have been reported and isolated from southafrica over the past few decades. these are: (1) duvenhage virus (gt4), isolated again in 2006 from a human fatality; (2) mokola virus (gt3), isolated irregularly, mostly from cats; (3) lagos bat virus (gt2) continually isolated over the past four years from epomophorus fruit bats and from incidental terrestrial animals and (4) rabies virus (gt1) - with two virus biotypes endemic ... | 2008 | 18634494 |
| a random grid based molecular epidemiological study on eblv isolates from germany. | germany has reported one of the highest levels of eblv cases in bats in europe. so far, all isolates originating from germany have been identified as eblv-1, using monoclonal antibodies, and a preliminary epidemiological study has indicated that there is a distinct geographical distribution of eblv-1 in germany. to further investigate the spatial and temporal distribution of eblv-1 variants in germany and their impact on molecular epidemiology, isolates were selected using a random grid sampling ... | 2008 | 18634492 |
| efficacy of a square presentation of v-rg vaccine baits in red fox, domestic dog and raccoon dog. | oral vaccination programmes conducted in rabies infected countries from eastern europe and eurasia should not be restricted to foxes but should target other major rabies vectors such as dogs and raccoon dogs as well. the objective of this experimental trial was to assess the protection induced by the vaccine by challenging these different species, which had been previously vaccinated intramuscularly with the square v-rg baits (produced in the us). different parameters were evaluated such as attr ... | 2008 | 18634487 |
| finnish-russian programme for the control of rabies (2005-2010). | the finnish-russian collaboration on rabies control began in 2000. this data summarizes the results of the scientific part of the programme, including rabies monitoring in russia and the molecular epidemiological studies with field viruses. | 2008 | 18634484 |
| rabies in the mongolian steppes. | historically, rabies in mongolia has been connected to the specific steppe and forest-steppe landscapes, known as the mongolian steppes. the main reservoirs of the rabies virus (rabv) are the wolf, red fox and corsac fox. fox rabies has been reported in mongolia since the early 1960s. eleven human rabies cases (0.4 per million inhabitants) were reported in mongolia from 1994-2004. wild animals predominated as a source of human infection: five people died following wolf bites, two were exposed to ... | 2008 | 18634480 |
| epidemiology of rabies in southeast europe. | rabies remains endemic within a number of countries in southeast europe including romania, bulgaria and turkey. with the probable expansion of the european union eastwards, it is likely that rabies elimination programs will be increased to reduce the burden of disease in new accession countries. a clear understanding of the epidemiology of the virus in this area of europe is vital before such programs are introduced. with the exception of turkey, the red fox (vulpes vulpes) is the principal dise ... | 2008 | 18634479 |
| rabies control in mexico. | rabies in dogs was unknown in the americas before the arrival of the spanish "conquistadores". until the mid-1980s rabies in animals and, in turn in humans, changed little from year to year, with the number of dog vaccinations reported annually rarely reaching one million. in mexico, the national rabies control programme using mass parenteral vaccination of dogs started in 1990 with about seven million dogs vaccinated the same year. the number of vaccinated dogs exceeded 10 and 15 million in 199 ... | 2008 | 18634477 |
| stray dogs in bangkok, thailand: rabies virus infection and rabies antibody prevalence. | in thailand, the animal most reported rabid is the stray dog. dog bite related rabies cases in humans account for 70-95% of rabies related deaths. the reported incidence of dog bites is highest in the central part of the country, especially in bangkok. this epidemiological survey shows that at least five different canine rabies virus types are present in bangkok. rabies antigen and antibody prevalence in stray dogs in bangkok was also investigated. saliva and serum samples were taken from 3,314 ... | 2008 | 18634473 |
| molecular epidemiology of lyssaviruses in eurasia. | the lyssavirus genus, a member of the rhabdoviridae family, consists of seven established related viruses (genotypes 1-7). rabies cases in eurasia are principally attributed to three of these genotypes, namely genotype 1 (rabv, classical rabies) and to a lesser extent genotypes 5 and 6 (european bat lyssaviruses type-1 and -2). in addition, four newly identified divergent lyssaviruses have been isolated from insectivorous bats. the molecular diversity of classical rabies viruses (genotype 1, rab ... | 2008 | 18634471 |
| pathogenic rabies virus alters host protein expression in the central nervous system: implications for neuronal dysfunction. | proteomics technology was employed to profile host responses to rabies virus (rabv) infection in order to understand how rabv infection results in neuronal dysfunction. in mice infected with wild-type (wt) rabv, the expression of proteins involved in ion homeostasis was altered. h+ atpase and na+/k+ atpase were up-regulated while ca2+ atpase was downregulated, which resulted in reduction of intracellular na+ and ca2+ concentrations. furthermore, infection with wt rabv resulted in down-regulation ... | 2008 | 18634469 |
| role of virus-induced neuropeptides in the brain in the pathogenesis of rabies. | rabies virus (rabv) infection is characterized by the rapid neuronal spread of rabv into the cns before a protective immune response is raised. therefore, a typical feature of rabv infection is the paucity of inflammatory reactions in the brain. here we examined whether the induction of immunosuppressive neuropeptides, in particular cgrp, may contribute to the ability of rabv to evade immune responses. rabv infection of mice caused a strong induction of calcitonin gene-related peptide (cgrp) in ... | 2008 | 18634468 |
| inflammatory responses in the nervous system of mice infected with a street isolate of rabies virus. | rabies virus causes severe encephalitis that is invariably fatal for the victim. however, the contribution of the virus and the host to damage of the cns is unclear. in order to investigate this we studied the neuropathology and cns gene expression patterns in a murine model of rabies using a 'street' isolate rv61. this virus was derived from a human case of disease. in this model, infection of the cns progresses rapidly following inoculation in the periphery, leading to extensive virus replicat ... | 2008 | 18634467 |
| efficacy and bait acceptance of vaccinia vectored rabies glycoprotein vaccine in captive foxes (vulpes vulpes), raccoon dogs (nyctereutes procyonoides) and dogs (canis familiaris). | the red fox, dog, and raccoon dog are known to play a major role in the global epidemiology of rabies. these three canid species were used to compare the appetency and efficacy of two commercial bait formats, each containing a single dose of vaccinia-rabies glycoprotein (v-rg) vaccine. square and rectangular raboral v-rg baits were fed to individual caged animal, and results were evaluated using three parameters: bait consumption, induction of rabies virus neutralizing antibodies and protection ... | 2008 | 18620017 |
| optimal control of vaccine distribution in a rabies metapopulation model. | we consider an sir metapopulation model for the spread of rabies in raccoons. this system of ordinary differential equations considers subpopulations connected by movement. vaccine for raccoons is distributed through food baits. we apply optimal control theory to find the best timing for distribution of vaccine in each of the linked subpopulations across the landscape. this strategy is chosen to limit the disease optimally by making the number of infections as small as possible while accounting ... | 2008 | 18613731 |
| amino acid at position 95 of the matrix protein is a cytopathic determinant of rabies virus. | the molecular mechanism involved in cytopathogenicity of rabies virus has not been fully elucidated yet. a fixed rabies virus nishigahara strain does not induce clear cytopathic effect (cpe) in mouse neuroblastoma (na) cells, whereas ni-ce strain, which was established after 100 passages of nishigahara strain in chicken embryo fibroblast cells, induces cpe that is characterized by rounding, shrinkage and detachment of the cells. in this study, to identify which viral gene is associated with the ... | 2008 | 18602710 |

| lyssaviruses: current trends. | various technological developments have revitalized the approaches employed to study the disease of rabies. in particular, reverse genetics has facilitated the generation of novel viruses used to improve our understanding of the fundamental aspects of rabies virus (rabv) biology and pathogenicity and yielded novel constructs potentially useful as vaccines against rabies and other diseases. other techniques such as high throughput methods to examine the impact of rabies virus infection on host ce ... | 2008 | 18585530 |
| development of a taqman real-time rt-pcr assay for the detection of rabies virus. | diagnosis of rabies relies on the fluorescent antibody test (fat) from brain impression smears. the mouse brain inoculation test is used to confirm fat but requires weeks until the result is known. taqman real-time pcr has been described for rabies viral rna detection; however, this is burdened by primer and probe binding site mismatches. the purpose of this study was to develop a taqman real-time rt-pcr assay as an adjunct to fat, based on national data of 239 rabies nucleoprotein sequences fro ... | 2008 | 18572257 |
| up-regulation of chemokine gene transcripts and t-cell infiltration into the central nervous system and dorsal root ganglia are characteristics of experimental european bat lyssavirus type 2 infection of mice. | european bat lyssaviruses (eblv) types 1 and 2 are closely related to classical rabies virus (rabv), and are capable of causing rabies in terrestrial mammals, including humans. the authors have investigated the murine host innate immune response in the brain, salivary gland, spinal cord, and blood, following peripheral inoculation with eblv-2. in the brain, increases in toll-like receptor-3 (tlr-3) transcript preceded overt disease, with a range of inflammatory gene transcripts increasing during ... | 2008 | 18569456 |
| high-resolution neuroanatomical tract-tracing for the analysis of striatal microcircuits. | although currently available retrograde tracers are useful tools for identifying striatal projection neurons, transported tracers often remained restricted within the neuronal somata and the thickest, main dendrites. indeed, thin dendrites located far away from the cell soma as well as post-synaptic elements such as dendritic spines cannot be labeled unless performing intracellular injections. in this regard, the subsequent use of anterograde tracers for the labeling of striatal afferents often ... | 2008 | 18561898 |
| complete genome sequence of a raccoon rabies virus isolate. | the entire genome of a mid-atlantic raccoon strain rabies virus (rrv) isolated in canada was sequenced; this is the second north american wildlife rabies virus isolate to be fully characterized. the overall organization and length of the genome was similar to that of other lyssaviruses. the nucleotide sequence identity of the raccoon strain ranged between 32.7% and 85.0% when compared to other lyssaviruses, while the deduced amino acid sequence identity ranged between 22.9% and 94.2% with the nu ... | 2008 | 18554740 |
| rabies in estonia: situation before and after the first campaigns of oral vaccination of wildlife with sag2 vaccine bait. | despite the extermination of stray animals and the compulsory vaccination of companion animals, rabies has been widely distributed over estonia for more than 30 years. the red fox and the raccoon dog are the rabies virus reservoirs. through a phare project, successive oral vaccination campaigns, using rabidog sag2 baits, were implemented in the autumn of 2005 in north estonia, and in the spring and autumn 2006 throughout the whole territory. after the autumn 2005 campaign, 73.5% of the raccoon d ... | 2008 | 18524435 |
