immunogenicity, efficacy and safety of an oral rabies vaccine (sag-2) in dogs.	a study of immunogenicity and efficacy of street alabama gif (sag-2) attenuated rabies virus vaccine in laboratory beagles was conducted. four groups of ten dogs each received either 1.0 ml of sag-2 orally on the tongue or 1.5 ml in baits. on day 180 postvaccination, all dogs were challenged with a street rabies virus. the antibody response in groups that received the vaccine directly on the tongue was higher than in those vaccinated with baits, but the difference between groups was not statisti ...	1996	8782341
rabies vaccine potency control: comparison of elisa systems for antigenicity testing.	potency control of inactivated rabies vaccines for human and veterinary application is usually undertaken by vaccination-challenge tests (e.g. the mouse potency test). for practical and ethical reasons there is an urgent need to replace in vivo potency control procedures, at least in part, by reliable methods of in vitro potency testing. quantitative elisa systems for potency control were developed using monoclonal antibodies (mabs) directed to the glycoprotein (gp) and to the nucleoprotein (np) ...	1996	8783156
induction of immunoreactive interleukin-1 beta and tumor necrosis factor-alpha in the brains of rabies virus infected rats.	interleukin-1 beta (il-1 beta) and tumor necrosis factor-alpha (tnf alpha) are important cytokines in the development of brain inflammation during pathological process. during rabies virus infection, the level of these proinflammatory cytokines are enhanced in the brain. in the present study we determined the cellular localization of these two cytokines by immunocytochemistry in brains of rats infected with rabies virus, at different time-intervals of the disease (day 1, 3, 4, 5 and at final sta ...	1996	8784259
development and evaluation of alternative testing methods for the in vivo nih potency test used for the quality control of inactivated rabies vaccines.	the potency control of rabies vaccines is routinely performed in a vaccination-challenge test (nih test), which induces substantial distress and suffering in laboratory mice. although, according to the recommendations by the who, partial replacement of this in vivo potency test by in vitro antigenicity testing is permitted, no internationally accepted alternative testing method is yet available. in the present study, we focussed on the use of monoclonal antibody-based elisa systems for the quant ...	1996	8785943
rabies: interactions between neurons and viruses. a review of the history of negri inclusion bodies.	the first clear-cut description of a virus-nerve cell interaction was made by adelchi negri in 1903 with the detection of cytoplasmic bodies (negri bodies) in subsets of neurons in the brain from rabies-infected animals. a biographical sketch of negri is given here; he was born in perugia, italy, in 1875 and died in pavia in 1912. in 1900 negri became assistant to camillo golgi, who encouraged him to study rabies-infected brains with histological techniques. the report of intraneuronal bodies de ...	1996	8804019
the glycoprotein genes and gene junctions of the fish rhabdoviruses spring viremia of carp virus and hirame rhabdovirus: analysis of relationships with other rhabdoviruses.	the nucleotide sequences of the glycoprotein genes and all of the internal gene junctions of the fish pathogenic rhabdoviruses spring viremia of carp virus (svcv) and hirame rhabdovirus (hirrv) have been determined from cdna clones generated from viral genomic rna. the svcv glycoprotein gene sequence is 1588 nucleotides (nt) long and encodes a 509 amino acid (aa) protein. the hirrv glycoprotein gene sequence comprises 1612 nt, coding for a 508 aa protein. in sequence comparisons of 15 rhabdoviru ...	1996	8806175
studies on unusual cytoplasmic structures which contain rabies virus envelope proteins.	we investigated unusual structures produced in bhk-21 cells infected with rabies virus (hep-flury strain). sellers' staining of the cells revealed, in addition to negri body-like structures (inclusion bodies), production of a fuchsin-stained cytoplasmic structure (fcps) which encircled the nucleus. the frequency of the fcps-forming cells increased as replication progressed. the fcps was different from the inclusion body because the former contained the viral glycoprotein (g) and matrix protein ( ...	1996	8811013
purification of a secreted form of recombinant rabies virus glycoprotein: comparison of two affinity tags.	expression of recombinant eukaryotic proteins in transfected mammalian cell lines has become an important approach for the characterization of the structure and function of these proteins. however, it is often difficult to recover and purify the recombinant proteins. therefore, the use of fusion proteins incorporating epitope or affinity tags has become more widespread. in this paper, we directly compare two affinity tags, the hexahistidyl tag and the biotin peptide mimetic, strep-tag, for use i ...	1996	8812859
budding of rabies virus particles in the absence of the spike glycoprotein.	budding of enveloped viruses from cellular membranes is believed to de pend on the presence of transmembrane spike proteins interacting with cytoplasmic virus components. to address the mechanism of rhabdovirus budding, we generated rabies virus mutants deficient for the glycoprotein g or the g cytoplasmic tail. we found that spikeless rhabdovirus particles were released from cells infected with the g-deficient mutant, demonstrating that a viral surface protein is not required to drive the buddi ...	1996	8601317

rabies postexposure prophylaxis--connecticut, 1990-1994.	in connecticut, the first case of animal rabies associated with the ongoing raccoon rabies epizootic was identified in march 1991; since then, cases of animal rabies have been confirmed in all eight counties of the state. because of heightened awareness of the potential for rabies and the nearly always fatal outcome of this disease, the numbers of persons in connecticut receiving rabies postexposure prophylaxis (pep) was suspected to have increased substantially during 1990-1994. in connecticut, ...	1996	8606682
human rabies--connecticut, 1995.	on october 3, 1995, a 13-year-old girl who resided in greenwich, connecticut, died from rabies virus infection. this was the first case of human rabies reported in a connecticut resident since 1932. this report summarizes the investigation of this case which indicated a bat as the probable source of her exposure.	1996	8609874
a replication-defective human adenovirus recombinant serves as a highly efficacious vaccine carrier.	in this manuscript, an e1 and e3 deleted adenoviral recombinant expressing the rabies virus glycoprotein (g protein) under the control of the cytomegalovirus early promoter was tested for induction of a rabies virus-specific immune response in mice. the construct was found to induce neutralizing antibodies and cytolytic t cells to rabies virus. mice vaccinated with the adenoviral construct either by the systemic route or by application into the airways were protected against a subsequent infecti ...	1996	8623532
the amino acid at the x position of an asn-x-ser sequon is an important determinant of n-linked core-glycosylation efficiency.	n-linked glycosylation is a common form of protein processing that can profoundly affect protein expression, structure, and function. n-linked glycosylation generally occurs at the sequon asn-x-ser/thr, where x is any amino acid except pro. to assess the impact of the x amino acid on core glycosylation, rabies virus glycoprotein variants were generated by site-directed mutagenesis with each of the 20 common amino acids substituted at the x position of an asn-x-ser sequon. the efficiency of core ...	1996	8626433
immunodominant epitopes defined by a yeast-expressed library of random fragments of the rabies virus glycoprotein map outside major antigenic sites.	nineteen yeast colonies secreting rabies virus glycoprotein (g) peptides immunoreactive with polyclonal anti-rabies virus sera were selected from a random expression library. the peptides, around 80 amino acids long, spanned amino acids 54-494 of the g protein. these peptides, together with two constructions including, respectively, immunodominant sites ii and iii, were analysed for their immunoreactivity with 40 anti-g protein monoclonal antibodies (mabs) composed of 12 mabs that reacted with s ...	1996	8627238
rabies and mortality in ethiopian wolves (canis simensis).	between october 1991 and february 1992, 41 of 53 known adult and subadult ethiopian wolves (canis simensis) in five adjacent packs in the bale mountains national park, ethiopia, died or disappeared. brain smears from two carcasses were positive for rabies by the immunofluorescence test, and rabies virus was isolated from the brains by mouse inoculation. based on monoclonal antibody tests on the mouse brains, we identified the virus as a minor variant of the serotype 1 rabies viruses found in dom ...	1996	8627941
characterization of a unique variant of bat rabies virus responsible for newly emerging human cases in north america.	the silver-haired bat variant of rabies virus (shbrv) has been identified as the etiological agent of a number of recent human rabies cases in the united states that are unusual in not having been associated with any known history of conventional exposure. comparison of the different biological and biochemical properties of isolates of this virus with those of a coyote street rabies virus (cosrv) revealed that there are unique features associated with shbrv. in vitro studies showed that, while t ...	1996	8643632
alteration of interleukin-1 alpha production and interleukin-1 alpha binding sites in mouse brain during rabies infection.	we have evaluated the effect of rabies virus infection on interleukin-1 alpha (il-1 alpha) production and its receptors in mouse brain. study of virus dissemination in the central nervous system (cns) showed a massive infection of main brain structures from day 4 post infection (p.i.) up to the agony stage on day 6 p.i. at the same time, il-1 alpha concentrations increased in cortical and hippocampal homogenates, whereas no change was detected in serum. in non-infected mice, il-1 alpha binding s ...	1996	8645096
rabies virus m protein expressed in escherichia coli and its regulatory role in virion-associated transcriptase activity.	rabies virus m protein was expressed in escherichia coli in the form of a fusion protein with maltose binding protein (mbp) and purified by amylose affinity column chromatography after extraction. in order to investigate the possible regulatory role of m protein in viral transcription, an assay system for rabies virion-associated transcriptase activity was established by using the ribonucleoprotein (rnp) cores prepared from purified virions. analysis of the products of the transcription assay sy ...	1996	8645103

medical microbiology	the family rhabdoviridae consists of more than 100 single-stranded, negative-sense, nonsegmented viruses that infect a wide variety of hosts, including vertebrates, invertebrates, and plants. common to all members of the family is a distinctive rod- or bullet-shaped morphology. human pathogens of medical importance are found in the genera lyssavirus and vesiculovirus.only rabies virus, medically the most significant member of the genus lyssavirus, is reviewed in this chapter.	1996	21413354
engineered virus targets hiv-infected cells: interview with garry nolan, ph.d. interview by john s. james.	a yale independent research team and a research team at the federal research center for virus diseases of animals in tubingen, germany have engineered viruses that will target and destroy hiv-infected cells while leaving uninfected cells intact. the yale team has genetically engineered the vesicular stomatitis virus and the german team has engineered the rabies virus to enter human cd4 cells in the same way hiv does, that is, by recognizing the hiv protein gp120 that appears on the surface of in ...	1997	11364688
[cloning and sequencing of nucleoprotein gene of chinese rabies virus vaccine strain (5ag)].	rabies virus 5ag strain (5agrv) is used to produce primary hamster kidney tissue culture vaccine against rabies in china. nucleoprotein (np), an important constituent of rabies virus, can intrigue th cell and induce b cell to produce antibody. in order to study the molecular and biological characteristics of 5ag np, we have cloned and sequenced the nucleoprotein gene. first, total rna was extracted from infected mouse brain by guanidine isothiocyanate one-step method, then the first strand cdna ...	1997	15619894
antibody responses to the hepatitis c virus e2 protein: relationship to viraemia and prevalence in anti-hcv seronegative subjects.	a small proportion of patients with chronic hepatitis c virus (hcv) infection show no serological responses to the hcv polypeptides incorporated in commercial iii generation immunoassays. to determine whether sera from these subjects contain antibodies to the highly immunoreactive second envelope polypeptide e2, which is not included in current anti-hcv assays, we studied 59 anti-hcv negative subjects who were found consistently to be hcv rna positive by polymerase chain reaction (pcr). controls ...	1997	8986942
canine distemper virus (cdv) infection of ferrets as a model for testing morbillivirus vaccine strategies: nyvac- and alvac-based cdv recombinants protect against symptomatic infection.	canine distemper virus (cdv) infection of ferrets causes an acute systemic disease involving multiple organ systems, including the respiratory tract, lymphoid system, and central nervous system (cns). we have tested candidate cdv vaccines incorporating the fusion (f) and hemagglutinin (ha) proteins in the highly attenuated nyvac strain of vaccinia virus and in the alvac strain of canarypox virus, which does not productively replicate in mammalian hosts. juvenile ferrets were vaccinated twice wit ...	1997	8995676
australian bat lyssavirus infection in three fruit bats from north queensland.	we report the case findings of australian bat lyssavirus infection in two black flying foxes (pteropus alecto) and one little red flying fox (pteropus scapulatus) from north queensland between january 1995 and august 1996. although the p. alecto case in january 1995 is the first recognised case of australian bat lyssavirus infection in australia, this was a retrospective diagnosis made after identification of the index case at ballina in may 1996. eight persons had exposure to the three bats. se ...	1997	9145563
[isolation and identification of lyssavirus strains from an area of slovakia where oral antirabies vaccine was administered].	the study was aimed at isolation and subsequent identification of strains of rabies virus by means of monoclonal antibodies from foxes killed in the vaccination zone within the complex preliminary monitoring of oral antirabies vaccination. the results obtained indicate that the vaccines for oral antirabies vaccination used in slovakia did not contain any vaccination strain pathogenic to the extremely sensitive target species-the fox (vulpes vulpes).	1997	9148571
antigens produced in plants by infection with chimeric plant viruses immunize against rabies virus and hiv-1.	the coat protein (cp) of alfalfa mosaic virus was used as a carrier molecule to express antigenic peptides from rabies virus and hiv. the antigens were separately cloned into the reading frame of alfalfa mosaic virus cp and placed under the control of the subgenomic promoter of tobacco mosaic virus cp in the 30brz vector. the in vitro transcripts of recombinant virus with sequences encoding the antigenic peptides were synthesized from dna constructs and used to inoculate tobacco plants. the plan ...	1997	9159151
regulation of n-linked core glycosylation: use of a site-directed mutagenesis approach to identify asn-xaa-ser/thr sequons that are poor oligosaccharide acceptors.	n-linked glycosylation can profoundly affect protein expression and function. n-linked glycosylation usually occurs at the sequon asn-xaa-ser/thr, where xaa is any amino acid residue except pro. however, many asn-xaa-ser/thr sequons are glycosylated inefficiently or not at all for reasons that are poorly understood. we have used a site-directed mutagenesis approach to examine how the xaa and hydroxy (ser/thr) amino acid residues in sequons influence core-glycosylation efficiency. we recently dem ...	1997	9163332
[a patient with rabies in the netherlands].	a 49-year-old moroccan man was admitted to hospital with chest pain and dyspnoea. the next day he had paresis of the left arm and because of respiratory arrest he was transferred to the intensive care unit. a fast-progressive neurological illness developed with flaccid tetraparesis, areflexia and a lowered level of consciousness. he died 11 days after admission. the strong clinical suspicion of rabies was confirmed by very high antibody titres in serum and csf and by positive immunofluorescence ...	1997	9173305

apoptosis plays an important role in experimental rabies virus infection.	cultured rat prostatic adenocarcinoma (at3) cells infected with the challenge virus standard (cvs) strain of fixed rabies virus showed characteristic morphologic features of apoptosis, evidence of oligonucleosomal dna fragmentation, and expression of the bax protein. cvs-infected bcl-2-transfected at3 cells did not demonstrate these features. adult icr mice inoculated intracerebrally with cvs showed morphologic changes of apoptosis, dna fragmentation, and increased bax expression in neurons, wit ...	1997	9188634
polymorphism of rabies viruses within the phosphoprotein and matrix protein genes.	although the rabies virus p and m genes, encoding the viral phosphoprotein and matrix protein respectively, have been characterised for a few laboratory-adapted strains, there is essentially no information on the variability of these two genes in wild-type rabies viruses. in this study rabies viruses, responsible for epizootics in different wildlife species in three geographically distinct areas of north america, have been characterised at the p and m gene loci. these data reveal that the m gene ...	1997	9191862
rabies viruses infect primary cultures of murine, feline, and human microglia and astrocytes.	recent studies have reported the detection of rabies viral antigens and virions in astrocytes and microglia of rabies-infected animals. as a first step toward understanding whether these glial cells may be involved in rabies virus replication, persistence, and/or pathogenesis, we explored their potential to be infected in vitro. primary cultures of murine, feline, and human microglia and astrocytes were infected with several different rabies viruses: two unpassaged street virus isolates, a cell ...	1997	9191865
an indirect immunofluorescent test for detection of rabies virus antibodies in foxes.	the blood-containing fluids in the thoracic cavity or blood from the heart from 177 red foxes (vulpes vulpes) in slovenia were evaluated for rabies antibodies by rapid fluorescent focus inhibition test (rffit) and an adapted indirect immunofluorescent test (iif) in 1994. we evaluated the usefulness of anti-dog fluorescein-isothiocyanate (fitc) conjugate instead of anti-fox fitc conjugate in detection of antibodies against rabies virus in fox sera. in the rffit test, 92 (52%) of the fox samples w ...	1997	9027703
an outbreak of vampire bat-transmitted rabies in cattle in northeastern mexico.	an outbreak of bovine rabies occurred on a ranch when cattle were bitten by vampire bats. microscopic lesions showed a nonsuppurative encephalitis with intracytoplasmic inclusion bodies. immunohistochemistry demonstrated viral antigen in the brain, and monoclonal antibodies identified a serotype 1 (vampire strain) of the rabies virus.	1997	9056070
a recombinant vaccinia-rabies virus in the immunocompromised host: oral innocuity, progressive parenteral infection, and therapeutics.	with the emergence of raccoons (procyon lotor) as the primary rabies reservoir in the united states of america, a recombinant vaccinia-rabies glycoprotein (v-rg) virus vaccine was developed that protected raccoons by the oral route from rabies infection. despite extensive laboratory evaluation, vaccine safety concerns remained about free-choice distribution for wildlife rabies control. in this study, the oral innocuity of v-rg virus was demonstrated in immunodeficient mice but parenteral exposur ...	1997	9066030
monoclonal antibody #5-2-26 recognizes the phosphatase-sensitive epitope of rabies virus nucleoprotein.	we prepared monoclonal antibodies (mabs) against the rabies virus n protein, among which one antibody (mab 5-2-26) was shown to lack reactivity with the phosphatase-treated n protein. the mab was able to recognize the sodium dodecyl sulfate (sds)-denatured n protein. the mab did not recognize the n-protein analogues produced in escherichia coli (e. coli), indicating that the n-gene products were not normally processed in e. coli after translation. on the other hand, the mab reacted normally with ...	1997	9087966

immune response to neonatal genetic immunization.	the effect of genetic immunization of neonatal mice was tested with a plasmid vector expressing the rabies virus glycoprotein. mice inoculated within 24 hr after birth with the plasmid dna developed antibodies as well as t helper cells to the rabies virus glycoprotein. the response could not be distinguished from that seen upon vaccination of adult mice. taken together, these data clearly show that the immune system, known to be prone to induction of immunological tolerance to some antigens appl ...	1997	9123835
identification of a phosphatase-sensitive epitope of rabies virus nucleoprotein which is recognized by a monoclonal antibody 5-2-26.	we have investigated a phosphatase-sensitive sequential epitope of the nucleoprotein (n), one of the phosphoproteins of rabies virus, which is recognized by the monoclonal antibody (mab) #5-2-26. the epitope was shared in common by all of the rabies virus strains we tested, including the hep, era, cvs and japanese strains (nishigahara and komatsukawa). thin layer chromatography of the acid hydrolyzates of 32p-labeled n protein showed that the protein contained phosphoserine and phosphothreonine ...	1997	9130235
occurrence of rabies in wolves of alaska.	we describe a rabies epizootic in northwest alaska (usa) during 1989 and 1990 which resulted in mortality to several different wolf (canis lupus) packs. four radio-collared wolves were confirmed to have rabies while evidence for seven others was strongly suggestive but not confirmed. the wolf population declined during the rabies epizootic; thus rabies may have been a significant limiting factor.	1997	9131553
mapping of monoclonal antibody epitopes of the rabies virus p protein.	thirty-six monoclonal antibodies (mabs) specific for the rabies virus p phosphoprotein were obtained from mice immunized with recombinant p (pv strain) produced in e. coli. all mabs reacted against the corresponding rabies virus protein by elisa and by western blot analysis and revealed the presence of cytoplasmic inclusions in rabies virus infected cells. the epitopes of seven mabs were mapped by testing their reactivity with protein fragments expressed from deletion mutants in transfected cell ...	1997	9010294
duration of immunity in foxes vaccinated orally with era vaccine in a bait.	red foxes (vulpes vulpes) vaccinated orally with the era strain of rabies vaccine in a bait were challenged after 83 mo. ten of 11 foxes that had seroconverted following vaccination resisted challenge with a virulent rabies virus which produced clinical signs of rabies in 6 of 6 unvaccinated foxes. five of 11 vaccinated animals retained titers of rabies virus neutralizing antibody throughout the period. although 6 of 11 had no detectable antibody at the time of challenge, 5 of these 6 resisted c ...	1997	9008799
molecular epidemiology of animal virus diseases.	in this review the application of methods of molecular epidemiology, particularly the combined approach of amplifying defined fragments of viral genomes using the polymerase chain reaction and subsequent nucleotide sequencing analysis, is described. emphasis is put on examples of a few important diseases (e.g. those caused by morbilliviruses, rhabdoviruses, pestiviruses and aphthoviruses) to demonstrate the impact of this methodology. molecular epidemiology is already an important and very sensi ...	1997	9270348
human rabies--montana and washington, 1997.	on january 5 and january 18, 1997, respectively, a man in montana and a man in washington died of neurologic illnesses initially suspected to be creutzfeldt-jakob disease (cjd) but diagnosed as rabies encephalitis during subsequent histologic examination on autopsy. the cases were not linked epidemiologically, and no secondary cases occurred. postexposure prophylaxis (pep) was administered to 113 potential contacts. this report summarizes the clinical presentations of the cases and the epidemiol ...	1997	9272584
procedures for reproducible detection of rabies virus antigen mrna and genome in situ in formalin-fixed tissues.	procedures allowing the reproducible in situ detection of rabies virus antigen and rnas (both genome and message) in formalin-fixed tissue are described. these procedures can be used on sequential tissue sections and thereby permit comparison of results from tests detecting both antigen and rna in the same tissue. this antigen-detecting procedure has also been used to identify both the phylogenetically distant rabies viruses from silver-haired bat and vampire bat and the rabies-related viruses m ...	1997	9274812
a cxcr4/cd4 pseudotype rhabdovirus that selectively infects hiv-1 envelope protein-expressing cells.	we show that a cellular virus receptor functions in the envelope of a virus, allowing selective infection of cells displaying the receptor ligand. a g-deficient rabies virus (rv) pseudotyped with cd4- and cxcr4-derived proteins selectively infected cells expressing hiv-1 envelope protein. envelope protein or cd4 antibodies blocked virus entry. pseudotype virus formation was most efficient with chimeric receptor proteins possessing the cytoplasmic tail of the rv g spike protein (cxcr4-rv and cd4- ...	1997	9298896
phage-displayed and soluble mouse scfv fragments neutralize rabies virus.	a phage-display technology was used to produce a single-chain fv antibody fragment (scfv) from the 30aa5 hybridoma secreting anti-glycoprotein monoclonal antibody (mab) that neutralizes rabies virus. scfv was constructed and then cloned for expression as a protein fusion with the g3p minor coat protein of filamentous phage. the display of antibody fragment on the phage surface allows its selection by affinity using an enzyme-linked immunosorbent assay (elisa); the selected scfv fragment was prod ...	1997	9300387

the current state of rabies prevention in europe.	in europe, from the late 1970s, the main reservoirs of rabies virus have been wild animals, mainly foxes, except in turkey, where dog rabies account for almost all cases. between 1977 and 1994, 198 human rabies cases were reported in europe. in most of these cases vaccination had not been performed. in europe, both tissue culture and nerve tissue vaccines are used with or without rabies immunoglobulin or serum, though the tissue culture vaccines have largely replaced the nerve tissue vaccines. i ...	1997	9218286
rabies and rabies research: past, present and future.	rabies is probably the oldest recorded infection of mankind. the development of the first rabies vaccine by pasteur surely had been hoped to eliminate or at least drastically reduce its incidence. however, this goal has not been achieved because rabies is maintained in many animal reservoirs, including both domestic and wild. there are still many aspects of the pathogenicity of rabies that are unknown. for example, we have no explanation for the long incubation period (up to 6 years). furthermor ...	1997	9218287
