completion of the rabies virus genome sequence determination: highly conserved domains among the l (polymerase) proteins of unsegmented negative-strand rna viruses.we have now completed the rabies genome structure by the cloning and the sequencing of the entire l gene and the 5' untranscribed region. the l gene encodes a single open reading frame 2142 amino acids in length (244,206 da) that corresponds to the viral rna-dependent rna polymerase. in contrast with other isofunctional proteins, the rabies polymerase exhibits a high degree of homology with the vesicular stomatitis virus polymerase, and a lesser degree, although significant, with those of sendai ...19883407152
[biological properties of variants of the rabies street virus].experiments in dogs inoculated intracerebrally with biological variants of paralytic (prv) and convulsive (crv) rabies virus isolated from the yak strain population of street rabies virus demonstrated distinct differences in the biological properties of the variants prv induced in dogs paralytic rabies with a short incubation period (average 6.4 days) and crv induced an atypical convulsive form characterized by attacks of tonic convulsions of the body, legs, and head twitching, and a longer incu ...19883414067
[the phenomenon of "early and stimulated death" in mice infected and then vaccinated against rabies].live (diluted) and inactivated rabies vaccines of low antigen content induce early and enhanced death in mice, inoculated before vaccination with a wild type of rabies virus. such vaccines, which neither induce interferon nor protect, produce a low level of antibodies which appear later than with vaccines of higher antigenicity. it is recommended to examine rabies vaccines not only by the usual (pre-exposure) potency test-nih test or modified nih test (one vaccination), but also by a post-exposu ...19883415193
interaction of rabies vaccine with human rabies immunoglobulin and reliability of a 2-1-1 schedule application for postexposure treatment.five commercially available rabies vaccines (hdcv, fbkc vaccine, pcec vaccine, pvrv and pdev) applied alone or combined with human rabies immunoglobulin (hrig) were administered, by random allocation, to 161 volunteer vaccinees, using the abbreviated 2-1-1 postexposure immunization schedule. protective levels of rabies antibody were demonstrated in all vaccinees by day 14, and in all but one vaccinee from day 21 to day 90. partial inhibition of the antibody response due to hrig was observed for ...19883420976

synthetic peptides in the study of the interaction of rabies virus and the acetylcholine receptor.the neurotropism of some viruses may be explained in part by the attachment of these viruses to host cell receptors that are present on or even largely restricted to neurons. rabies virus is an rna virus that, after a period of replication in muscle, gains access to the central nervous system, where it selectively infects certain neuronal populations. the nicotinic acetylcholine receptor occurs in high density at the neuromuscular junction and is present in the central nervous system. although s ...19883041753
immunization of arctic foxes (alopex lagopus) with oral rabies vaccine.arctic foxes (alopex lagopus) were successfully immunized against rabies using an orally-administered, liquid sad-bhk21 live virus vaccine in a sausage bait. immunization was determined by serologic response and by resistance to challenge with an arctic rabies virus strain. virus was not shed in saliva following oral vaccination, indicating that arctic foxes would not infect other foxes after ingesting this vaccine. high antibody levels were present in all experimental foxes 2 wk following initi ...19883045347
history of rabies: advances in research towards rabies prevention during the last 30 years.the great amount of basic research on rabies virus in the last 30 years has led to important improvements in the methods used for the prevention of rabies--methods that include rapid laboratory diagnosis, production of cell culture vaccine, and the means for controlling wildlife rabies. these advances are briefly reviewed.19883060952
ecology and epidemiology of fox rabies.although fox rabies has been reported in every country that has foxes, current foci of fox rabies are limited to europe and north america. the fox rabies virus has unique characteristics that seem to be the result of adaptation through successive passages, i.e., high pathogenicity for the fox, excretion in saliva of a high proportion of infected animals, and low frequency of postinfection immunity. the spread of fox rabies is greatly favored by the characteristics of the genus vulpes--ubiquity, ...19883060953
human rabies and its prevention: an overview.human rabies is underreported, but it clearly is still a frequent medical problem that is virtually confined to tropical countries. rabies encephalitis remains essentially incurable, and most patients die at home, their terrible symptoms unpalliated by sedatives or analgesics. recent attempts to cure rabies in well-equipped intensive care units have failed, a situation reemphasizing the importance of preventive measures. the great advances that have been made in understanding the rabies virus an ...19883060958
rabies virus infection of myotubes and neurons as elements of the neuromuscular junction.the neuromuscular junction represents a site of transit for both fixed and street rabies viruses. infection of cultured rat myotubes by fixed rabies virus was found to be restrictive, and although fluorescence observations showed that cells were infected, there were no infectious virus particles in the supernatant of infected myotubes. in contrast, infection of myotubes with street rabies virus produced infectious virus particles, and kinetic studies noted a growth cycle in these cells. neurons ...19883060959
animal models in the pathogenesis and treatment of rabies.various animal models have been developed for the study of the pathogenesis of rabies and of methods for halting its spread. the long incubation period and the relatively low mortality observed in human rabies can be mimicked by injecting mice in the footpad with rabies virus. to relate the immune response and efficacy of treatment to the situation in humans, however, it is necessary to corroborate the results in rodents with those in subhuman primates. methods effective and safe in subhuman pri ...19883060960
antipeptide monoclonal antibodies inhibit the binding of rabies virus glycoprotein and alpha-bungarotoxin to the nicotinic acetylcholine receptor.it has been reported that binding to muscle nicotinic acetylcholine receptor at the post-synaptic membrane is an important event of the rabies virus neurotropism. the binding site can be located within the 190-203 region of the virus glycoprotein sharing a high degree of homology with the "toxic loop" of the curare-mimetic snake neurotoxins. we have synthesized a tetradecapeptide corresponding to this glycoprotein region and used it, following conjugation with an immunogenic carrier to raise mab ...19883062388
[diagnosis of rabies by cell culture].mouse inoculation test (mit) is a highly sensitive test for rabies diagnosis but slow and expensive. to detect rabies virus an in vitro technique using neuro 2a cell culture (cc) was compared with mit in two laboratories. in one laboratory, cc appeared to be on the whole more sensitive than mit, nevertheless mit was the only one to detect some positive samples. in the other laboratory, mit was more sensitive. these results justify the use of cc for epidemiological diagnosis but emphasize the int ...19883064966
monoclonal antibodies to mokola virus for identification of rabies and rabies-related viruses.rabies and rabies-related virus strains were studied by using a panel of monoclonal antibodies directed against either nucleocapsid proteins or cell surface antigens of mokola virus (mok-3). each strain was used in parallel to infect cultured cells and mice. then, the patterns of reactivity of the different monoclonal antibodies were determined by the immunofluorescent-antibody staining procedure. on cells, the monoclonal antibodies differentiated fixed rabies virus strains (serotype 1) from rab ...19883068246
the present status of rabies vaccine development and clinical experience with rabies vaccine.attempts to control human rabies have a long history: animal and human vaccines provide efficient weapons for prevention. in this presentation, we would like to consider the different rabies vaccines available for human use, and particularly the modern vaccines produced in cell culture. rabies virus is considered as an unique virus, but in fact, 5 groups of rabies fixed strains are used throughout the world to produce human rabies vaccines: pasteur, beijing, flury, fuenzalida and sad strains. th ...19883070767

[new research on the oral vaccination of wild animals].successful oral immunization of wildlife against rabies has strongly stimulated research in the past decade. new approaches have been developed for vaccine production (e.g.: use of recombinant vaccines) as well as for better potency or safety testing procedures. it appears that man should also consider two important phenomena which already existed in nature before his research. the first one is an adaptation of the rabies virus, by serial passages, which favours the spreading of the disease amon ...19883077440
epidemiology and diagnosis of rabies in greece.during the decade 1951-1960, 8626 rabies cases were reported among domestic animals in greece and 53 deaths in humans. during the decades 1961-1970, 1971-1980 cases were reduced to 3009 and 242, respectively, while no more cases in man occurred since 1970. vaccination campaigns of dogs, besides the low prevalence of rabies among wild animals, resulted in its eradication from the country. immunofluorescence is the method used for diagnosis.19883077442
morphologic appearance of inclusion bodies and their association with the antigenic composition of naturally occurring rabies viruses.a total of 112 rabies virus-infected skunk brain samples from naturally occurring cases (64 from missouri, 48 from kentucky) were code labeled and grouped into two morphologic categories according to the appearance and size of the discrete particles observed by immunofluorescent-antibody staining. the reactivity of the blind-labeled samples was then determined using a panel of 23 antinucleocapsid monoclonal antibodies to test whether morphologic appearance was associated with antigenicity. two c ...19883277995
studies of era/bhk-21 rabies vaccine in skunks and mice.era rabies vaccine virus grown in bhk-21 13s cells (era/bhk-21) and street rabies virus were titrated in mice by intracerebral, intranasal and intramuscular inoculation. mice were also given undiluted era/bhk-21 in baits. skunks were given undiluted era/bhk-21 in baits and by intramuscular, intranasal and intestinal inoculation. virus neutralizing antibody titers against rabies virus were measured over a three month observation period. the surviving skunks were challenged by intramuscular inocul ...19883280109
use of the avidin-biotin peroxidase system to detect rabies antigen in formalin-fixed paraffin-embedded tissues.we stained rabies-infected nervous and salivary-gland tissues fixed in formalin or acetone and embedded in paraffin with the avidin-biotin peroxidase system. with this system, rabies-virus antigen was detected in neurons, glandular acinar cells, and vascular endothelial cells more effectively than by immunofluorescence, especially when tissues were enzyme-digested with pronase before immunoperoxidase staining. the avidin-biotin peroxidase system should be useful for routine diagnosis, retrospect ...19883284894
measurement of rabies-specific antibodies in carnivores by an enzyme-linked immunosorbent assay.we describe an indirect enzyme-linked immunosorbent assay (elisa) that utilizes anticanine immunoglobulin for the measurement of rabies-specific antibody in the sera of the major domestic and wildlife reservoirs of rabies in north america. sufficient cross-reactivity was found to exist between anticanine igg and serum antibody from all carnivores tested, including dogs, cats, foxes (vulpes vulpes), skunks (mephitis sp.) and raccoons (procyon lotor). with sera of most species, good correlation wa ...19883286905
serological survey for rabies antibodies in raptors from california.fifty-three newly captive birds of prey were tested serologically for neutralizing antibodies against rabies virus, using a fluorescent focus inhibition test. no significant antibody titers were detected with this sensitive and specific technique in any of these birds. this study supports the contention that free-ranging birds of prey are of limited importance in the epidemiology of rabies.19883286906
successful oral rabies vaccination of raccoons with raccoon poxvirus recombinants expressing rabies virus glycoprotein.two infectious raccoon poxvirus (rcn) recombinants for expressing rabies virus surface spike glycoprotein (g) were produced by homologous recombination between raccoon poxvirus dna and chimeric plasmids previously used for production of vaccinia virus recombinants. expression of g protein was controlled by vaccinia virus promoter p7.5 (early/late class) or by p11 (late class). immunoprecipitation of infected cell extracts indicated that both of the rcn recombinants directed faithful expression o ...19883291388

controlled organization of multimolecular complexes of enveloped virus glycoproteins: study of immunogenicity.some technological and immunological problems facing the preparation of subunit viral vaccines are discussed. solubilization of enveloped virus glycoproteins with various detergents has been studied. it has been demonstrated that a novel non-ionic detergent, mesk, can be used to prepare the glycoproteins of enveloped viruses in defined supramolecular forms: monomers, micelles, liposomes and multimeric complexes. these preparations have been tested for immunogenicity. it has been shown that the i ...19882848380
fowlpox virus as a vector in non-avian species.examination of the members of the poxvirus family reveals a large and diverse group with members infecting almost every animal species. to a large extent, members of the individual genera have a broad host range and infect a number of animal species, although, as baxby has pointed out, successful experimental inoculation of a species does not necessarily mean that this species provides a natural host for that virus. avipox viruses, together with swinepox virus occupy a somewhat unique position i ...19882854335
recombinant fowlpox virus inducing protective immunity in non-avian species.the natural host of fowlpox virus is limited to avian species. when inoculated into non-avian tissue culture cells, however, fowlpox virus can initiate an abortive infection. a fowlpox virus was engineered to express rabies virus glycoprotein. on inoculation of the recombinant virus into either avian (permissive) or non-avian (non-permissive) cells, the rabies glycoprotein was expressed as a membrane-associated antigen. inoculation of the fowlpox virus recombinant into six different species of m ...19882854338

recognition of rabies and rabies-related viruses by t cells derived from human vaccine recipients.human peripheral blood mononuclear cells and t-cell lines and clones from individuals immunized with rabies pm vaccine were tested for the ability to recognize antigenic determinants in rabies and rabies-related viruses in an antigen-induced proliferation assay. some, but not all, of the t cells from these individuals cross-reacted with various laboratory strains of rabies virus with rabies-related viruses such as duvenhage and mokola. in addition, these t cells were shown to react with epitopes ...19882457112
genetic restriction and fine specificity of human t cell clones reactive with rabies virus.rabies virus-specific t cell clones isolated from a human vaccine recipient were studied for their fine specificity and genetic restriction using synthetic peptides of the viral ag and mouse fibroblasts transfected with human mhc genes. two clones were found to react with an epitope present in the rabies glycoprotein, which was presented by the hla-dr7 molecule. other t cell clones recognized synthetic epitopes corresponding to the rabies nucleoprotein in association with the hla-dr7 or hla-dqw3 ...19882459225
interleukin-2 production in vitro: a new approach to the study of rabies vaccine immunogenicity as appraised by testing different glycoprotein presentations.when injected as an immunosome presentation (molecules anchored to preformed liposome), rabies glycoprotein (gp) is capable of protecting animals against rabies either before or after viral infection. the presentation of the gp molecules in the correct form seems to be essential for the induction of antirabies protection. this condition must be taken in account in the making-up of a rabies subunit vaccine. in order to study the relationship between the immune responses induced by the rabies gp a ...19882461004
immunity against the european bat rabies (duvenhage) virus induced by rabies vaccines: an experimental study in mice.protection experiments were performed in mice with different inactivated vaccines prepared with the fixed rabies virus strains: pm (pitman-moore), pv4 (pasteur virus) and lep (flury lep) against an intracerebral challenge with a european bat virus (duvenhage, strain hamburg, duv3). all vaccines protected mice against challenge with cvs (challenge virus standard). vaccines prepared with pv4 protected mice against a duv3 challenge. on the contrary, pm or lep vaccines did not protect mice against a ...19882461007
the molecular biology of rabies viruses.comparative nucleotide and deduced amino acid sequence analyses of the rna and proteins of several fixed rabies virus strains have allowed detailed characterization of structural-functional relations of individual virus components. several unique features of rabies viruses have been deduced from the complete nucleotide sequences of four of the five genes and the four intergenic regions of the genome. the most extensively analyzed rabies virus gene has been that of the surface glycoprotein. direc ...19882462742
[effect of daily immunization and antirabies gamma-globulin on the development of immune t-killers in inbred mice infected with the street rabies virus].daily administration of vaccine as well as combined use of antirabies gamma-globulin and vaccine were shown not to induce the production of immune t-killers possessing protective properties in adoptive transfer in mice pre-infected with street rabies virus in contrast to a single administration of a shock dose of antigen. immune splenocytes protected 31-43% of mice infected with street rabies virus in a dose of 2-4 im ld50 and did not protect the animals infected with a dose of 12 im-ld50. after ...19882464240

a rabies agglutination test (rat) for rabies antibody detection.an agglutination test has been developed for the detection of rabies antibodies after human vaccination. the rabies agglutination test (rat) is based on the capability of specific antibody to agglutinate sensitized polystyrene (or latex) beads. in the rat, latex beads were coated, in a first step, with inactivated and purified rabies virus (pv strain adapted and propagated on bhk-21 cells) and, in a second step, with bovine serum albumin. negative control beads were coated with bovine serum albu ...19883198658
immunization of foxes against rabies with a vaccinia recombinant virus expressing the rabies glycoprotein.foxes were vaccinated orally (by bait), gastrically (by stomach tube) and by scarification with a vaccinia recombinant virus expressing the rabies glycoprotein. neutralizing antibodies against rabies virus were detected at two weeks postvaccination in 8/8 foxes in the bait-fed group, in 3/6 foxes inoculated by stomach tube and in 2/2 of the scarified foxes. after challenge at three months postvaccination with street rabies virus, all foxes that had developed antibodies were protected. the high r ...19883202696
skunk rabies.in north america, the number of cases of rabies diagnosed in skunks generally exceeds that in either raccoons or foxes. enzootic skunk rabies occurs mainly in four geographic regions: (1) southern ontario and quebec and upper new york state; (2) the north central united states and the canadian provinces of manitoba, saskatchewan, and alberta; (3) california; and (4) south central united states (texas and several adjacent states). rabies in these areas (in skunks and, to a large extent, in other ...19883206070
monoclonal antibody studies of rabies in insectivorous bats of the united states.isolates of rabies virus from terrestrial animals in six geographically separate rabies enzootic areas of the united states were examined with a panel of monoclonal antibodies to the viral n protein. characteristic differences in immunofluorescence reactions permitted the formation of five antigenically distinct reaction groups from the 328 isolates tested. distinctive reaction patterns were also identified for isolates from four species of bats. these observations were used to determine the rol ...19883206073
oral rabies vaccination: an overview.the vaccination of wild animals against rabies was first attempted in 1962 after the repeated failure of poisoning or trapping to control the movement of the disease in these species. the initial requirements of such a vaccine were that it be efficacious and inexpensive, that it allow animals to immunize themselves, and that it not cause vaccine rabies in the target species. foxes were chosen for research purposes because they are a problem species and are exquisitely susceptible to rabies. the ...19883206074
pathogenesis of rabies virus infection in dogs.most dogs experimentally infected with street rabies virus showed clinical signs of rabies before death, but up to 18% of the dogs died without showing detectable signs of illness. in dogs showing signs, rabies was not invariably fatal. up to 20% of dogs recovered without any supportive treatment. some dogs inoculated with american (southern texas) or ethiopian canine street virus excreted virus in their saliva up to 14 days before signs appeared. there was no relation between the time of excret ...19883206080
mass vaccination campaign against rabies: are dogs correctly protected? the peruvian experience.in a mass vaccination campaign conducted in peru in march 1985, 270,000 dogs (65% of the estimated dog population) were vaccinated over the course of 1 month with an inactivated tissue culture vaccine. since that time no human rabies cases have been reported; in addition, the number of animal rabies cases has declined to only three from a previous mean of 292 cases per year since 1980. a serologic survey was also done to determine the immune response among randomly selected vaccinated dogs, with ...19883206083
failure to thrive, wasting syndrome, and immunodeficiency in rabies: a hypophyseal/hypothalamic/thymic axis effect of rabies virus.studies of rabies virus in several animal models consistently showed hypothalamic infection, hypophyseal infection, dramatic growth impairment (in the form of failure to thrive), wasting syndrome, and immune depletion. rabies virus infection was studied through routine monoclonal antinucleocapsid antibody immunofluorescence and through a peroxidase-antiperoxidase immunoperoxidase method. the latter was modified to detect the in situ production of growth hormone by uninfected and rabies virus-inf ...19883206086
antigenic diversity of the glycoprotein and nucleocapsid proteins of rabies and rabies-related viruses: implications for epidemiology and control of rabies.rabies virus-specific monoclonal antibodies (mabs) have served to describe operationally the topography of the antigenic structure of the glycoprotein and nucleocapsid proteins of rabies virus. with the use of nucleocapsid protein-specific mabs and cleavage fragments of the nucleoprotein and phosphoprotein, it has been possible to identify the chemical structure of two antigenic sites of the nucleoprotein and one antigenic site of the phosphoprotein. antisera produced to synthetic peptides that ...19883206089
development of animal recombinant dna vaccine and its efficacy in foxes.rabies is prevalent in most parts of the world. an extensive reservoir of the disease is present in the population of wild animals. the fox in particular is a major vector of the disease in north america and europe. although attempts to control rabies by vaccination of wild carnivores with attenuated rabies virus have met with some success, this approach remains controversial. the potential of a recombinant vaccinia virus expressing the rabies glycoprotein for the protection of foxes against rab ...19883206090
efficacy of a vaccinia-rabies glycoprotein recombinant virus vaccine in raccoons (procyon lotor).raccoon rabies exists in epizootic proportions in the southeastern and mid-atlantic regions of the united states, but efficacious oral vaccines for control of rabies in this important vector have not been previously demonstrated. alternatively, a vaccinia recombinant virus vaccine (v-rg) expressing the era (evelyn-rokitnicki-abelseth) rabies virus glycoprotein was highly immunogenic for laboratory animals and raccoons by the intradermal, intramuscular, and oral routes. raccoons that ate a synthe ...19883206091
glimpses into the future of rabies research.much is now known about the chemical composition of the rabies virus but little is known of its pathogenesis. techniques used commonly in molecular biology research can and should be applied to questions about the behavior of the rabies virus and the responses of the challenged host so that new generations of vaccines may be produced. the vaccinia-rabies glycoprotein recombinant vaccine acts by inducing neutralizing antibody to rabies virus and completely protects various species of vaccinated a ...19883206092

the epidemiology of the human rabies threat in the grand duchy of luxembourg.epidemiological data were recorded and blood samples were obtained from a group of 297 individuals from luxembourg who had been in contact with rabies-infected or -suspected animals from 1979 to 1985, and who had been vaccinated with a complete course of hdcs rabies vaccine. the majority of the subjects were farmers aged between 30 and 59. the most frequent source of infection was cattle, followed by foxes, sheep and cats. dogs were in the fifth position only, probably as a direct result of obli ...19883207500
immunological relationships between rabies virus and rabies-related viruses studied with monoclonal antibodies to mokola virus.specific monoclonal antibodies (mab) were prepared against a rabies-related lyssavirus, mokola virus. a strain isolated in the central african republic, mok-3, was used as immunogen. after 3 fusions more than 90 hybridoma cultures secreting mab were identified. according to their different patterns of reactivity against rabies and rabies-related viruses, 61 ascites fluids were obtained. the antibody class was igm for 2 of them and igg for 59. they were specific for one of the 4 major viral prote ...19883207504
fatal encephalitis caused by a bat-borne rabies-related virus. clinical findings.the clinical findings are described in the first reported european case of fatal encephalitis of bat origin caused by a rabies-related virus. a bat zoologist developed the symptoms of rabies 51 days after his last exposure to a bat bite. the clinical disease of 23 days duration was a combination of the paralytic and 'furious' forms of rabies. serial baep and eeg recordings, ct and mr scans of the brain, as well as csf findings, demonstrated severe ascending destruction of the brain. an unusual p ...19883208067
comparison of spongiform lesions in experimental scrapie and rabies in skunks.striped skunks were inoculated intracerebrally with the scrapie agent (suspension of brain from a naturally infected suffolk sheep) or intramuscularly with street rabies virus (suspension of salivary glands from naturally infected skunks). those given the scrapie agent developed clinical signs of weakness, posterior ataxia, and emaciation after incubated periods of 8 to 23 months. those inoculated with rabies virus developed clinical signs of rabies (aggressive behavior, hyperexcitability, ataxi ...19883213430
a field trial in belgium to control fox rabies by oral immunisation.campaigns of fox vaccination against rabies were carried out in belgium in september 1986 and june and september 1987. the sad b19 attenuated strain of rabies virus was inserted into baits which were distributed over an area of 2100 km2 at a density of 11 baits/km2. as recommended by the world health organisation, the efficacy and the innocuity of the method were controlled in the field and in the laboratory. samples of blood and brain and jaw were taken from foxes which were shot or found dead ...19883218039
