The aim of this study was to develop a highly sensitive and specific one-step multiplex reverse transcriptase PCR assay for the simultaneous and differential detection of Rift Valley Fever virus (RVFV), bluetongue virus (BTV), rinderpest virus (RPV), and Peste des petits ruminants virus (PPRV).
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
The currently used vaccine strain of Rinderpest virus was derived by serial passage of the highly virulent Kabete 'O' strain (KO). A full-length cDNA copy of the KO strain was made from which a virus identical in pathogenicity to the wild-type virus was rescued. A series of chimeric viruses was
Rinderpest virus (RPV) is a member of the genus Morbillivirus in the family Paramyxoviridae which causes an acute and often fatal disease in large ruminants. To examine the immune response to the virus nucleocapsid (N) protein, a recombinant vaccinia virus expressing RPV nucleocapsid protein
A Kabete 'O' strain of rinderpest virus enhanced in virulence was inoculated subcutaneously into four cows which were between six and eight months pregnant. All the cows developed clinical signs of rinderpest from the third day after inoculation and shed high titres of virus in their ocular and
Starting from the clinical symptoms and the pathological-anatomical changes hints are given on the diagnosis of the rinderpest and how to distinguish it from other diseases. The paper discusses the differential diagnosis of the rinderpest with respect to mucosal disease, malignent catarrhal fever,
Diffusible rinderpest virus antigens were demonstrated in increasing quantities in ocular and lymph node biopsies from rinderpest-infected cattle using agar gel immunodiffusion (AGID) and counterimmunoelectrophoresis (CIEP) tests. Positive samples were detected from the second day of pyrexia to two
Rabbits were intravenously inoculated with an attenuated rinderpest virus (L strain), and general patterns of the disease were investigated. The rabbits developed fever with concomitant occurrence of diarrhea and lymphopenia. Early production of interferon was followed by a rise of neutralizing
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
Six Freesian steers were subcutaneously inoculated with the virulent rinderpest virus strain Kabete "0" and sacrificed at the height of fever. Sections of formalin-fixed, paraffin-embedded tissues were stained according to the peroxidase anti-peroxidase (PAP) technique. Labelling of viral antigen,
East Coast fever (ECF) is the most important tick-borne disease in eastern, central and southern Africa and caused an estimated loss of US $186 million in 1989 in the 11 countries where it occurs. It was brought to southern Africa with cattle from Tanzania in 1901 and, over the next 3 years,
Five Holstein heifers (approximately 8 months of age and weighing 225-275 kg) were inoculated subcutaneously with 1,000 TCID50 of rinderpest virus, virulent Kabete O strain. They become clinically ill 2 to 5 days post-inoculation, with fever (40 C to 41.5 C), conjunctivitis, and diarrhea. All were
