| development and distribution of rinderpest virus antigen in experimentally infected goats. | three goats, experimentally infected with rinderpest virus were examined for the development and distribution of precipitating antigens in various tissues and secretions using the agar gel immunodiffusion test. virus antigens were detected in ocular secretions and lymph node biopsies from the second to the fourth and fifth days of pyrexia, respectively, but were not detected in nasal secretions. precipitating antigens were demonstrated in various lymphoid organs, the lung and abomasum of a goat ... | 1988 | 3140470 |
| characterization of antinuclear antibodies induced in rabbits by rinderpest virus infection. | rabbits infected with the l strain of rinderpest virus (rv) produced high titres of antinuclear antibodies (ana) which reached a maximum two weeks after inoculation but rapidly disappeared by 6-8 weeks. these anas reacted with hela cells by indirect immunofluorescence test resulting in a homogeneous nuclear fluorescence. in order to investigate the target antigens of anas, the effects on the nuclear fluorescence pattern of pretreating hela cells were examined: dnase 1 treatment resulted in a dec ... | 1988 | 3058091 |
| [an immunoenzyme test used for the detection of antibodies to rinderpest: the advantage of using a purified virus cultivated in a cell line]. | two types of in vitro assays (enzyme immunoassay and sero-neutralization test) were compared for their ability to detect antibodies to rinderpest virus in field sera from west african bovines. purified virus grown on vero cells (ag/vero) or bovine kidney cells (ag/bk), were tested as antigen in enzyme-linked immunoassays (eia). the results of the comparative evaluation of the two antigens by eia, prove that ag/vero did enhance the sensitivity and the specificity of the test in comparison to ag/b ... | 1988 | 3053021 |
| use of the caprinised strain of rinderpest virus for potency testing an attenuated cell culture rinderpest vaccine. | the caprinised strain of rinderpest virus was inoculated into goats to produce a challenge stock. these goats were kept with control animals (goats, sheep, calves). in this trial the caprinised strain was shown to have a mild pathogenicity for goats and it spread to one of two contact goats but not from goats to other species. the caprinised strain was then tested on cattle where a febrile reaction was observed. the caprinised strain also did not spread between cattle. the cattle vaccinated with ... | 1988 | 3041655 |
| detection of rinderpest antigen by latex agglutination test. | a slightly modified latex agglutination test was applied for detection of rinderpest antigen. the antigen was added to sensitized latex particles in the presence of hyperimmune antiserum to facilitate agglutination. out of 129 samples tested by latex agglutination (la), solid phase aggregation of coated erythrocytes (space), reverse phase passive haemagglutination (rpha) and counter immunoelectrophoresis (cie) test, 86.0, 86.8, 84.4 and 79.8 per cent, respectively, were found positive. | 1988 | 2902777 |

| differentiation of rinderpest and peste des petits ruminants viruses using specific cdna clones. | the morbilliviruses which infect ruminants, rinderpest (rpv) and peste des petits ruminants (pprv), are difficult to distinguish serologically. they can be distinguished by differential neutralisation tests and by the migration of the major virus structural protein, the nucleocapsid protein, on polyacrylamide gels. both these methods are time consuming and require the isolation of live virus for identification; they are not suitable for analysis of material directly from post-mortem specimens. w ... | 1989 | 2723018 |
| immunization with a vaccinia recombinant expressing the f protein protects rabbits from challenge with a lethal dose of rinderpest virus. | a cdna clone containing the complete coding sequence of the rinderpest fusion protein (f) gene was inserted into the thymidine kinase gene of vaccinia virus (wr strain) under the control of the 7.5k early/late vaccinia virus promoter. all forms of the f protein, i.e., the glycosylated f0 precursor, the unglycosylated f1 protein, and the glycosylated f2 protein, were detected in cells infected with the recombinant virus. vaccination of rabbits with the recombinant virus induced antibodies which r ... | 1989 | 2718375 |
| an epidemiological model of rinderpest. ii. simulations of the behaviour of rinderpest virus in populations. | fixed parameters for different hypothetical strains of rinderpest virus (rv) and different susceptible populations are described together with details of their derivation. simulations were then carried out in a computer model to determine the effects that varying these parameters would have on the behaviour of rv in the different populations. the results indicated that virulent strains of rv are more likely to behave in epidemic fashion whereas milder strains tend towards persistence and the est ... | 1989 | 2711465 |
| an epidemiological model of rinderpest. i. description of the model. | the development of an epidemiological model of rinderpest in cattle and wildlife populations is described. the model uses a state-transition structure, incorporating a stochastic element through the use of monte-carlo methods modified to allow large populations to be simulated. the potential applications include the estimation of "safe" host population immunity rates and the design of cost-effective rinderpest vaccination programmes. | 1989 | 2711464 |
