| serological studies with the virus of peste des petits ruminants in nigeria. | it was possible to distinguish separate serological responses when experimental goats were inoculated with either rinderpest virus or peste des petits ruminants virus. examination of field samples established that peste des petits ruminants occur commonly in nigerian sheep and goats although some villages have escaped recent infection. there was no evidence of infection with rinderpest in these animals. | 1979 | 262608 |
| antiviral effects of double-stranded rna from rice dwarf virus on infection of mice with western equine encephalitis virus. | a single administration (1 to 10 mg/kg) of rice dwarf virus rna (rdv-rna) prior to virus challenge reduced the mortality of mice infected with western equine encephalitis (wee) virus. the protective effect of rdv-rna was significantly higher than that of polyinosinic-polycytidylic acid. however, when these rnas were given after virus infection, the protective effect was negligible. the titer of circulating interferon in mice reached a peak about 5 hr after injection of these rnas and remained at ... | 1977 | 333233 |
| [effect of estrogens on infection of rabbits with cattle plague virus previously administered to rabbits]. | the rabbit bovipest virus selectively destroys the lymphoid b line in the rabbit. estrogens inhibit this destruction when they are administered before the infection which leads are to think that they act on membrane sites of the lymphocytes. | 1977 | 408043 |
| studies on the methods of preparation of rinderpest hyperimmune sera in rabbits. | the procedures for the preparation of the rinderpest hyperimmune sera in rabbits were studied by comparing the sera from rabbits immunised by three different schedules of inoculations. the best sera for use in immunodiffusion tests were obtained from rabbits inoculated first with rinderpest hyperimmune serum and lapinised virus, and then with lapinised virus mixed with oil adjuvant twice at weekly intervals. those rabbits which received additional one or two intravenous inoculations with lapinis ... | 1977 | 410129 |

| classification of peste des petits ruminants virus as the fourth member of the genus morbillivirus. | peste des petits ruminants (ppr) is a virus disease of sheep and goats in west africa. when first described, the virus was considered a variant of rinderpest virus. the biological and physicochemical characteristics of the virus indicate that it is closely related to measles, rinderpest and canine distemper viruses. these three viruses form the genus morbillivirus of the paramyxoviridae. ppr virus is sufficiently distinct from these 3 viruses to justify considering it as the fourth member of the ... | 1979 | 457363 |
| experimental infection of domestic pigs with the virus of peste des petits ruminants. | pigs could be subclinically infected with pprv by inoculation or contact with infected goats. there was no evidence that the virus could spread to uninfected pigs or goats and pigs are not considered important in the epidemiology of pprv. | 1979 | 462558 |
| the isolation of peste des petits ruminants virus from nigerian sheep and goats. | four isolates of peste des petits ruminants virus were obtained from sick nigerian sheep and goats. one was identical antigenically with the prototype senegalese strain. a cross relationship was found between peste des petits ruminants virus and rinderpest virus based on neutralisation in vitro. | 1979 | 472495 |

| development of a diploid cell line from fetal calf lung for virus vaccine production. | details of isolation and replication of a fetal calf diploid cell (fcdc) is given. from the karyological point of view, the fairly large number of chromosomes existing in metaphase spreads made counting rather tedious. lack of practical classification was another problem which made reference to individual chromosomes difficult. by increasing the population doubling of this cell, a tendency of telocentric chromosomes to undergo centric fusion was observed. susceptibility of fcdc to different viru ... | 1976 | 1036404 |
| studies on recovery mechanism from rinderpest virus infection in rabbits. i. effect of anti-thymocyte serum and thymectomy. | the role of cell-mediated immunity in recovery from rinderpest virus infection in rabbits was investigated by application of immunosuppressive procedures, i.e., treatment with anti-thymocyte serum and combined treatment with thymectomy and anti-thymocyte serum, both of which were confirmed to depress significantly cell-mediated immunity in rabbits. the immunosuppressed animals recovered in almost the normal fashion in terms of clinical signs, of virus clearance from the blood and lymphoid tissue ... | 1976 | 1087650 |
| a study of immunoglobulin m antibody to measles, canine distemper, and rinderpest viruses in sera of patients with subacute sclerosing panencephalitis. | seven boys were studied who had the clinical features of subacute sclerosing panencephalitis (sspe) and whose brain histology was consistent with sspe. measles antigen was detected in the seven brains by the direct fluorescent antibody method. three out of the seven boys had in their sera measles specific immunoglobulin m (igm) which was detected by the indirect fluorescent antibody method, and the cell receptors for it were acetone stable. a prozone effect was noted in the sera of two patients. ... | 1975 | 1097472 |
| diminished antibody response to rinderpest vaccination in cattle undergoing experimental east coast fever. | the immunocompetence of cattle undergoing east coast fever (ecf) reactions of varying degrees of intensity was evaluated using the neutralising antibody response of these cattle to the vaccine response was found in animals undergoing severe ecf reactions. the results suggest that the massive lymphoid cell involvement of such severe ecf reactions diminishes the immune responsiveness of cattle to rinderpest vaccine. | 1975 | 1166127 |
| experimental infection of white-tailed deer with rinderpest virus. | white-tailed deer (odocoileus virginianus) succumbed to experimental infection with virulent rinderpest (rp) virus that was also lethal to cattle and goats. the deer developed clinical signs typical of rp and died 5 and 6 days post-inoculation. infection was confirmed by recovery of virus from blood before death, from lymph node tissue after necropsy, and demonstration of specific complement fixing antigen in those tissues. electron micrographs of infected vero cell cultures revealed extracellul ... | 1975 | 1195493 |

| observations on rinderpest in kenya, 1986-1989. | rinderpest was confirmed in kenya in 1986, 1987, 1988 and 1989. three epidemiologically distinct events appear to have occurred: repeated outbreaks in west pokot district related to cross-border movement of stock, an outbreak in marsabit district in 1987 (thought to have been caused by illegal movement of cattle, possibly in vehicles, from countries further north) and a series of related outbreaks in and near nairobi between 1988 and 1989 due to the unauthorized movement from abattoirs and holdi ... | 1992 | 1472724 |
| round table on morbilliviruses in marine mammals. | since 1988 morbilliviruses have been increasingly recognized and held responsible for mass mortality amongst harbour seals (phoca vitulina) and other seal species. virus isolations and characterization proved that morbilliviruses from seals in northwest europe were genetically distinct from other known members of this group including canine distemper virus (cdv), rinderpest virus, peste des petits ruminants virus and measles virus. an epidemic in baikal seals in 1987 was apparently caused by a m ... | 1992 | 1481361 |
| sequence analysis and editing of the phosphoprotein (p) gene of rinderpest virus. | we have cloned the cdna of the phosphoprotein (p) gene of the virulent (kabete "o") strain of rinderpest virus and provided a comparative analysis of its sequence with that of the p genes of measles, canine distemper, and phocid distemper viruses. the gene encodes two overlapping open reading frames of 1521 and 531 nucleotides. use of the first atg would produce a p polypeptide of 507 amino acids with a calculated molecular weight of 54,344. the second atg would produce a c polypeptide of 177 re ... | 1992 | 1529555 |
| the genes encoding the phospho- and matrix proteins of phocine distemper virus. | the nucleotide sequences of the phosphoprotein (p)/v/c and matrix (m) protein genes of phocine distemper virus (pdv) have been determined and the deduced amino acid sequences of the proteins derived from these genes compared with those of the other morbilliviruses. the 1655 nucleotides of the p gene encode a phosphoprotein of 507 amino acid residues (from nucleotide numbers 60 to 1583) which is 75% identical to that of canine distemper virus (cdv). the c proteins of the two viruses are 73% ident ... | 1992 | 1535099 |
| molecular characterization of phocine distemper virus: gene order and sequence of the gene encoding the attachment (h) protein. | generation of a set of cdna clones covering the n, p/v/c, m, f, h and part of the l gene of phocine distemper virus (pdv) has been described. the gene order of pdv determined from a physical as well as a transcriptional map, was identical to that of the other morbilliviruses so far studied. the h gene sequence (1951 nucleotides) contains one large open reading frame which encodes a protein of 607 amino acids, identical in length to that of the h protein of the convac strain of canine distemper v ... | 1992 | 1588321 |
| phocine distemper virus, the agent responsible for the 1988 mass mortality of seals. | the biochemical characterisation of phocine distemper virus (pdv) has shown that pdv is related to but clearly distinct from canine distemper virus (cdv) and relative to its relationship with cdv is only remotely related to the other morbilliviruses, namely measles virus (mv) or rinderpest virus (rpv) and peste-des-petits-ruminants virus (pprv). comparative studies with monoclonal antibodies indicate that the virus is serologically closely related to cdv with many conserved epitopes, particularl ... | 1992 | 1594934 |
| the nucleotide and deduced amino acid sequence of the m gene of phocid distemper virus (pdv). the most conserved protein of morbilliviruses shows a uniquely close relationship between pdv and canine distemper virus. | the nucleotide sequence of the matrix gene (m) of a recently identified morbillivirus, phocid distemper virus (pdv), was determined and the amino acid composition deduced. the m gene of pdv shared many characteristics with the corresponding gene in other morbilliviruses. the nucleotide homology with the closely related canine distemper virus (cdv) was maximum at 67% followed by measles virus (mv) (58%) and rinderpest virus (rpv) (56%). the length of the 5' long untranslated region of pdv (408) w ... | 1992 | 1604930 |
| a competitive elisa using anti-n monoclonal antibodies for specific detection of rinderpest antibodies in cattle and small ruminants. | a competitive elisa (c-elisa) using monoclonal antibodies (mabs) which bind to the nucleo-protein (np) of rinderpest virus (rpv) for detection of rpv antibodies in cattle and small ruminant sera is described. unlike virus neutralisation test (vnt), this test using mab ivb2-4, can detect specific rpv antibodies without showing a cross-reaction with antibodies to peste-des-petits ruminants-virus (pprv); by contrast, when mab ve4-1 is used the test detects both rpv and pprv antibodies, including lo ... | 1992 | 1626365 |

| sequence analysis of the genes encoding the nucleocapsid protein and phosphoprotein (p) of phocid distemper virus, and editing of the p gene transcript. | the nucleotide and deduced amino acid sequences of two genes of phocid distemper virus (pdv) were determined by cdna cloning and sequencing. the long open reading frame of the gene encoding the nucleocapsid (n) protein is presented. as with other morbilliviruses, the phosphoprotein (p) gene of pdv was found to be located after the 5' end of the n gene and before the 3' end of the matrix protein gene. the p gene was shown to have the capacity to encode three distinct proteins, p, v and c, in anal ... | 1992 | 1634877 |
| identification of epitope(s) on the internal virion proteins of rinderpest virus which are absent from peste des petits ruminants virus. | monoclonal antibodies (mab) raised against the rbok vaccine strain of rinderpest virus were characterized by radio-immunoprecipitation (ripa) and in the indirect elisa using measles (mv), distemper (cdv), rinderpest (rpv) and peste des petits ruminants viruses (pprv). those found to be specific for the matrix (m) protein and the nucleocapsid (n) protein could be classified into different groups on the basis of the anti-morbillivirus mab classification scheme; a number of these mab showed a selec ... | 1991 | 1709543 |
| antigenic and functional characterization of rinderpest virus envelope proteins using monoclonal antibodies. | a total of 24 monoclonal antibodies (mabs) against the haemagglutinin (h) and the fusion protein (f) of rinderpest virus (rpv) were used to characterize their antigenic structure and biological properties, and to analyse natural variation in the envelope proteins of morbilliviruses. the anti-h and anti-f mabs defined seven and three distinct antigenic sites, respectively. the mabs to six sites on h were able to neutralize the infectivity of rpv. the addition of guinea-pig complement or anti-mous ... | 1991 | 1714940 |
| analyses of baseline survey data on rinderpest in bahr el ghazal province, with proposal of an improved vaccination strategy against rinderpest for southern sudan. | results from analyses of baseline surveillance data on rinderpest are used for proposing an improved vaccination strategy against rinderpest in southern sudan. sera from 4,074 (47%) of the total sample of 8,565 cattle collected in a series of cross-sectional surveys in 400 cattle camps in the bahr el ghazal province of southern sudan were tested for rinderpest antibodies using the standard virus neutralisation test (vnt) technique: 77.4% were positive while 22.6% gave negative results. the data ... | 1991 | 1763441 |
| viruses in the phytoreovirus genus of the reoviridae family have the same conserved terminal sequences. | the 5'- and 3'-terminal nucleotide sequences of the dsrna genome segments of rice dwarf virus (rdv) and rice gall dwarf virus (rgdv), members of the phytoreovirus genus of the reoviridae family, were determined and compared with those of wound tumour virus (wtv). the 3' tetranucleotides of the plus strand of all genome segments of rdv and rgdv were found to be the same (---ugau 3'), except for segment 9 of rdv which had the 3'-terminal sequence---cgau 3'. the conserved 3'-terminal sequence (---u ... | 1991 | 1765764 |
| the nucleotide sequence and deduced amino acid composition of the haemagglutinin and fusion proteins of the morbillivirus phocid distemper virus. | the amino acid composition of the two surface proteins of the recently isolated morbillivirus phocid distemper virus (pdv) were deduced from the nucleotide sequence. the fusion (f) protein of pdv exhibited characteristics similar to those of other morbillivirus f proteins. the overall amino acid similarity with its closest homologue, canine distemper virus (cdv), was 72%. from the context of the starting codons and the requirement for a hydrophobic signal peptide, it is likely that translation o ... | 1991 | 1765768 |
