| preliminary studies on an unusual poxvirus of the western grey squirrel (sciurus griseus griseus) of north america. | particles of a poxvirus found in californian western grey squirrels have overall dimensions indistinguishable from those of the poxviruses of the genera orthopoxvirus and leporipoxvirus, but have surface structures somewhat reminiscent of virions of members of the genus parapoxvirus. extracts of tissues infected with the squirrel poxvirus cross-react in gel-diffusion tests with extracts of tissues infected with californian myxoma virus, but not with a similar preparation infected with a south am ... | 1975 | 181346 |
| myxomatosis: the transmission of a highly virulent strain of myxoma virus by the european rabbit flea sphilopsyllus cuniculi (dale) in the mallee region of victoria. | the european rabbit flea spilopsyllus cuniculi (daley was introduced into australia to act as a vector of myxoma virus. it was first released in the semi-arid mallee region of victoria in 1970 where epizootics cuased by field strains of myxoma virus occur each summer. introductions of the readily identified lausanne strain were made annually following the release of the flea. the introductions were successful and the strain persisted for up to 16 weeks despite competition from field strains. the ... | 1977 | 270525 |
| innate resistance to myxomatosis in wild rabbits in england. | wild rabbits (oryctolagus cuniculus) from one study area in england have been used over a period of 11 years to investigate the possible appearance of innate resistance to myxomatosis. rabbits of 4-6 weeks old were captured alive, retained in the laboratory until at least 4 months old, and then infected with a type of myxoma virus which kills 90-95% of laboratory rabbits. observations were made of symptoms, mortality rate and survival times.in the first 4 years of the study (1966-9), mortality r ... | 1977 | 270526 |
| myxomatosis: changes in the epidemiology of myxomatosis coincident with the establishment of the european rabbit flea spilopsyllus cuniculi (dale) in the mallee region of victoria. | outbreaks of myxomatosis during the winter or spring have coincided with the establishment of the european rabbit flea in the mallee region. the severity of these outbreaks has varied from causing complete suppression of the normal spring increase in rabbit numbers to being completely ineffective in a year in which late spring rains allowed rabbit breeding to extend into the early summer.in 1973 and 1974 effective spring myxomatosis caused heavy mortality in kittens before they emerged from the ... | 1978 | 569676 |
| myxomatosis in the mallee region of victoria, australia. | sharp reductions in the wild rabbit (oryctolagus cuniculus (l.)) population in the mallee are associated with annual myxomatosis epizootics. the extent to which the population reductions are the direct result of the epizootics varies with time of epizootic occurrence. all grazing animals in the mallee are under nutritional stress each summer and autumn. when the epizootic occurs during the early summer heavy losses occur in a previously healthy population. similar losses which occur in the late ... | 1978 | 701787 |
| myxomatosis: the occurrence of antibody to a soluble antigen of myxoma virus in wild rabbits, oryctolagus cuniculus (l.), in victoria, australia. | the occurrence of antibody of myxoma virus in wild rabbits following epizootics is highest in the semi-arid north-west of victoria and lowest in temperate southern victoria. occurrence ranges up to about 90% in the north-west and to about 70% in the south except on the western plains where epizootics are rare and antibody occurrence seldom exceeds 30%. the establishment of the european rabbit flea may be changing the pattern of occurrence of antibody in the north-west by causing spring outbreaks ... | 1978 | 701788 |
| myxomatosis: passive immunity in the offspring of immune rabbits (oryctolagus cuniculus) infested with fleas (spilopsyllus cuniculi dale) and exposed to myxoma virus. | kittens with maternal antibodies to myxoma virus, the offspring of rabbits which had recovered from myxomatosis, were exposed to fleas contaminated with myxoma virus and/or contact with infected rabbits from birth. all kittens died or became infected before 8 weeks of age. when compared with adult animals similarly infected the kittens showed no advantage in terms of survival time or recovery rate attributable to maternal antibodies. flea transmission of virus was found more effective than conta ... | 1975 | 1054058 |
| myxomatosis: the virulence of field strains of myxoma virus in a population of wild rabbits (oryctolagus cuniculus l.) with high resistance to myxomatosis. | the virulence of field strains of myxoma virus is increasing in the mallee region of victoria where the resistance of the rabbit to myxomatosis is high. this suggests that the climax association will be a moderately severe disease. | 1975 | 1056963 |
| the differential transmissibility of myxoma virus strains of differing virulence grades by the rabbit flea spilopsyllus cuniculi (dale). | laboratory studies showed that few rabbit fleas (spilopsyllus cuniculi (dale)) transmitted myxomatosis after removal from wild rabbits (oryctolagus cuniculus (l) that had been infected for fever than 10-12 days, irrespective of the virulence of the myxoma virus strain involved. rabbits infected with fully virulent (grade i) strains died within 10-15 days and few fleas from these hosts became infective; averaging all the samples takem. 12% of the fleas were infective. also, few fleas acquired inf ... | 1975 | 1058245 |
| myxomatosis: population dynamics of rabbits (oryctolagus cuniculus linnaeus, 1758) and ecological effects in the united kingdom. | in 1953-1955, myxomatosis spread among rabbits (oryctolagus cuniculus) in the united kingdom, causing 99% mortality. subsequently, there was a gradual increase in rabbit numbers. by 1955, the ministry of agriculture, fisheries and food (maff) had already found attenuated strains of myxoma virus. by 1970, genetic resistance had appeared. in the 1970s, mortality declined to 47-69% with only approximately 25% of rabbits infected, giving a field mortality of 12-19%. however, myxomatosis is persisten ... | 1992 | 1305856 |
| deletion of the growth factor gene related to egf and tgf alpha reduces virulence of malignant rabbit fibroma virus. | the role of the epidermal growth factor homologue in malignant rabbit fibroma virus (mrv) pathogenicity was investigated by constructing a viral growth factor deletion mutant (mrv-gf-). since mrv is a recombinant virus with a myxoma virus background but possesses some terminal sequences derived from shope fibroma virus, the growth factor gene in mrv is in fact identical to shope fibroma growth factor (sfgf). although no significant differences were detected in the in vitro characteristics of mrv ... | 1992 | 1309274 |
| virus-induced loss of class i mhc antigens from the surface of cells infected with myxoma virus and malignant rabbit fibroma virus. | shope fibroma virus (sfv) is a leporipoxvirus that causes localized benign fibromas in immunocompetent adult rabbits that spontaneously regress due, in part, to a cell-mediated immune response. myxoma virus (myx) and malignant rabbit fibroma virus (mrv) are related leporipoxviruses that induce rapidly lethal generalized infections accompanied by tumors and immunosuppression. because only these latter two viruses are known to compromise cell-mediated antiviral responses, cell surface levels of cl ... | 1992 | 1309843 |
| myxoma virus m11l orf encodes a protein for which cell surface localization is critical in manifestation of viral virulence. | myxoma virus (myx) induces extensive immunosuppression in infected rabbits and is associated with high levels of mortality. the virus encodes multiple gene products designed to circumvent the cellular immune response to the viral infection. deletion analysis has shown that the m11l open reading frame (orf) is an important virulence factor which downregulates leukocyte infiltration of myx-induced tumors. to investigate the role of the m11l protein in viral pathogenesis, we sequenced the myx m11l ... | 1992 | 1413498 |
| encoding of a homolog of the ifn-gamma receptor by myxoma virus. | many poxvirus-encoded virulence factors have been identified as proteins that are secreted from infected cells. the major secreted protein (37 kilodaltons) from cells infected with myxoma virus is encoded by the m-t7 open reading frame. this protein has significant sequence similarity to the human and mouse receptors for interferon-gamma (ifn-gamma). furthermore, the myxoma m-t7 protein specifically binds rabbit ifn-gamma and inhibits the biological activity of extracellular ifn-gamma, one of th ... | 1992 | 1455233 |
| a myxoma virus intergenic transient dominant selection vector. | the purpose of this study was to construct an intergenic transfer vector which can be used for the generation of recombinant myxoma viruses (mvs) expressing a foreign gene insert. recombinant mvs expressing the escherichia coli lacz gene were constructed in vitro by transfection of mv-infected rabbit cells with a transfer expression vector, and isolated under growth conditions selecting for transient expression of the e. coli gpt gene. the effect of inserting foreign dna sequences between the vi ... | 1992 | 1469364 |
| the myxoma virus thymidine kinase gene: sequence and transcriptional mapping. | the myxoma virus thymidine kinase (tk) gene is encoded on a 1.6 kb saci-sali restriction fragment located between 57.7 and 59.3 kb on the 163 kb genomic map. the nucleotide sequence of this fragment as well as 228 bp from the adjacent sali-aa2 fragment was determined and found to encode four major open reading frames (orfs). three of these orfs are similar in nucleotide sequence to orfs l5r and j1r, and the tk gene of vaccinia virus (vv). the fourth orf, mf8a, shows similarity to the orfs found ... | 1992 | 1538190 |

| deletion analysis of two tandemly arranged virulence genes in myxoma virus, m11l and myxoma growth factor. | myxoma virus (myx) is a leporipoxvirus of rabbits that induces a lethal syndrome characterized by disseminated tumorlike lesions, generalized immunosuppression, and secondary gram-negative bacterial infection. a myx deletion mutant (vmyx-gf- delta m11l) was constructed to remove the entire myxoma growth factor (mgf) coding sequence and that for the c-terminal five amino acids of the partially overlapping upstream gene, m11l. unexpectedly, this deletion completely abrogates the capacity of myx to ... | 1992 | 1629952 |
| myxoma virus expresses a secreted protein with homology to the tumor necrosis factor receptor gene family that contributes to viral virulence. | poxviruses are known to contain a large number of open reading frames, particularly near the termini of the viral genome, that are not required for growth in tissue culture. however, many of these gene products are believed to play important roles in determining the virulence of the virus by modulating the host immune response to the infection. recently it has been shown that shope fibroma virus encodes, within the terminal inverted repeats, a protein (t2) related to the cellular tumor necrosis ... | 1991 | 1651597 |
| synthesis and structure-activity study of myxoma virus growth factor. | myxoma virus growth factor (mgf) is an 85-residue peptide derived from the gene product of a dna tumor virus that infects rabbits. the carboxyl domain of mgf possesses about 40% sequence homology with the epidermal growth factor (egf). this egf-like domain covering residues 30-83 was synthesized and found to possess putative activities of egf. it was, however, about 200-fold less active than egf in the competitive binding of egf receptor in a431 cells and the stimulation of [3h]-thymidine uptake ... | 1991 | 2009268 |
| molecular analysis of immunosuppression induced by virus replication in lymphocytes. | the relationship between immunosuppression and oncogenesis can be determined by studying the molecular interactions between tumor-inducing viruses and lymphocytes. we approached this study by using a unique system of two genetically related leporipoxviruses, malignant fibroma virus (mv), and shope fibroma virus (sfv). mv induces a syndrome of a highly lethal, disseminated myxosarcoma, severe immune suppression, and replicates in lymphocytes both in vivo and in vitro. in contrast, sfv causes a be ... | 1990 | 2159037 |

| the group selection of variola minor in the americas: an anthroponootic analogue for the myxomatosis epizootic in australia. | it is an axiom of many parasitology texts that host-parasite systems coevolve toward a state approximating commensalism. while this hypothesis has an apriori intuitive appeal there is little empirical evidence to support it. the only documented case of a parasite evolving toward avirulence is the group selection of less virulent strains of the myxoma virus in the australian rabbit population. it is hypothesized here that group selection also accounted for the appearance of variola minor in the a ... | 1986 | 2423858 |
| isolation and plaque purification of a syncytial forming component of myxoma virus. | using the endpoint dilution and plaque purification technique performed on rabbit kidney cells, two stable syncytial clones of myxoma virus have been isolated. no eosinophilic intracytoplasmic inclusion bodies nor intranuclear granulations could be detected in cells infected with these clones. traditional plaques with the central area of detached cells surrounded by round cells also could not be recognized. however, when enough virus was added, one large complete syncytium developed in 24 on the ... | 1989 | 2582742 |

| possible windborne spread of myxomatosis to england in 1953. | an analysis of the meterological conditions showed that the first outbreaks of myxomatosis in s.e. england in 1953 could have resulted from wind carriage of insects infected with myxoma virus from northern france. south-easterly winds on the night 11-12 august would have carried the insects 120-160 km from the départements of nord, pas de calais and somme across the english channel to near edenbridge, kent. the flight would have taken 6.5-8.5 h at wind speeds of 15-22 km h-1. on the night 11-12 ... | 1987 | 2881798 |
| tumorigenic poxviruses: genomic organization of malignant rabbit virus, a recombinant between shope fibroma virus and myxoma virus. | the genome of malignant rabbit virus (mrv), a newly discovered tumorigenic poxvirus of rabbits, has been analyzed using cloned dna probes from shope fibroma virus (sfv) and myxoma virus. under high stringency conditions for southern blotting such that sfv probes do not cross-hybridize with myxoma virus dna, it is demonstrated that greater than 90% of the mrv genome has been derived from myxoma virus, and that approximately 10 kb of sfv-derived sequences have substituted for a similar amount of m ... | 1985 | 2981446 |
| characterization, molecular cloning, and physical mapping of the shope fibroma virus genome. | five strains of shope fibroma virus (sfv), a strain of rabbit myxoma virus, and a strain of vaccinia virus were compared by restriction endonuclease digestion of their viral dnas. restriction digest patterns revealed that sfv and rabbit myxoma, both members of the leporipoxvirus genus, were distinct from vaccinia, an orthopoxvirus. all strains of sfv examined had a high degree of nucleotide sequence homology as shown by conservation of restriction sites within their genomes. however, restriction ... | 1985 | 2998033 |
| transcriptional mapping of early rna from regions of the shope fibroma and malignant rabbit fibroma virus genomes. | malignant rabbit fibroma virus (mv) is a recombinant poxvirus derived from shope fibroma virus (sfv) and rabbit myxoma virus (d. s. strayer, e. skaletsky, g. f. cabirac, p. a. sharp, l. b. corbeil, s. sell, and j. l. leibowitz, 1983a, j. immunol. 130, 399-404; w. block, c. upton, and g. mcfadden, 1984, virology 140, 113-124). we report here the transcriptional mapping of early rnas transcribed from the sfv sequences within mv and from the corresponding regions in sfv. hybridization analysis and ... | 1986 | 3016986 |

| myxomatosis. the effect of age upon survival of wild and domestic rabbits (oryctolagus cuniculus) with a degree of genetic resistance and unselected domestic rabbits infected with myxoma virus. | the response of wild and domestic rabbits with a degree of genetic resistance to myxomatosis has been shown to be markedly affected by the age at which they were infected with a virulent strain of the virus. the response, in terms of mean survival time and percentage survival, fell with increasing age from 10 to 30 weeks with little change thereafter. | 1970 | 5267123 |
| myxomatosis: the introduction of the european rabbit flea spilopsyllus cuniculi (dale) into wild rabbit populations in australia. | 1. the european rabbit flea spilopsyllus cuniculi (dale) bred successfully in wild rabbits on three properties in new south wales and, within two breeding seasons, almost every rabbit shot within a quarter of a mile of a release site was infested.2. it was demonstrated that the flea transmitted myxoma virus in the field.3. in areas where more than 75% of the rabbits shot at the beginning of the breeding season were flea-infested and myxoma virus was present, populations failed to show the expect ... | 1971 | 5285938 |
