Pathogen Characteristics

Top of page

The virus is a member of the family Bunyaviridae, genus Phlebotomus. The virus is 90-110 nm in diameter, with an internal core of single stranded RNA surrounded by an envelope. It is inactivated by lipid solvents, sodium deoxycholate and formalin. Major polypeptides are G1,G2 and N. Other members of the Phlebotomus fever group show cross relationships with RVF virus on complement fixation, haemagglutination, ELISA or indirect fluorescent antibody tests, and pose potential problems in diagnosis. The virus serum neutralisation tests are specific. One Phlebovirus, which presents a practical diagnostic problem, is sandfly fever, which may overlap in its range with RVF in North Africa. The other related viruses, which exist in South America and elsewhere, should not pose diagnostic problems.

Strain variation

All the strains of RVF virus thus far isolated have been shown to be immunologically and serologically identical. An analysis of strains isolated during epizootics in many parts of Africa and in Egypt has shown few differences when analysed with some 59 monoclonal antibodies and by electrophoretic migration patterns of the structural and non structural proteins. They were all remarkably similar. Fingerprinting and sequencing of isolates have demonstrated some differences, which may be of value in epidemiological mapping. All the isolates identified in Kenya over 30 years have shown similar pathogenicity.

Most strains of pantropic RVF, that have been isolated from many parts of Africa have shown similar levels of virulence when expressed in the same host genotype. Some variation in the pathogenicity of the viscerotropic RVF virus strains has, however, been reported, but this may reflect their passage history and the genotype of the host species exposed in the field and in the laboratory. The Wistar–Furth strain of inbred rats shows differences in the pathogenicity of the Egyptian isolates compared with others from sub-Saharan Africa. The Egyptian isolates are highly pathogenic for these rats, all die within 48 h. The susceptibility was associated with the presence or absence of a particular gene. When other inbred strains of rats (LEW & MAXX) were inoculated with the same virus strains, they were comparatively resistant to the fatal liver disease, but some developed a necrotizing encephalitis. Strains such as the Lunyo from Uganda and Smithburn (SNS), and several other cell or mouse adapted isolates, show differences in pathogenicity compared with field isolates. The SNS has been neuro-adapted by passage in infant mouse brain, which has resulted in a loss in pathogenicity for the disease hosts. Similar loss of pathogenicity has been demonstrated by cell passage and by exposure of the virus to mutant inducers. The MP 12 strain shows a mutagen-induced reduction in virulence with great potential as a modified live virus vaccine. The C-13 strain (74HB59) has been described as a naturally occurring low virulence strain of RVF, originally classified as Zinga virus, but subsequently shown to be RVF.

Disease(s) associated with this pathogen is/are on the list of diseases notifiable to the World Organisation for Animal Health (OIE). The distribution section contains data from OIE's Handistatus database on disease occurrence.
