13. Serological tests for detecting Rift Valley fever viral antibodies in sheep from the Nile Delta.
To determine the accuracy of serological methods in detecting Rift Valley fever (RVF) viral antibodies, we examined serum samples obtained from 418 sheep in the Nile Delta by using five tests. The plaque reduction neutralization test (PRNT) was considered the standard serological method against which the four other tests were compared. Twenty-four serum samp

14. Characterization of the Golgi Retention Motif of Rift Valley Fever Virus GN Glycoprotein
As Rift Valley fever (RVF) virus, and probably all members of the family Bunyaviridae, matures in the Golgi apparatus, the targeting of the virus glycoproteins to the Golgi apparatus plays a pivotal role in the virus replication cycle. No consensus Golgi localization motif appears to be shared among the glycoproteins of these viruses. The viruses of the fami

15. The Carboxy-Terminal Acidic Domain of Rift Valley Fever Virus NSs Protein Is Essential for the Formation of Filamentous Structures but Not for the Nuclear Localization of the Protein
The ambisense S segment of Rift Valley fever (RVF) virus (a phlebovirus in the Bunyaviridae family) codes for two proteins: the viral complementary-sense RNA for the N nucleoprotein and the genomic-sense RNA for the nonstructural protein NSs. Except for the fact that the NSs protein is phosphorylated and forms filamentous structures in the nuclei of infected

16. Growth of Pathogenic Virus in a Large-Scale Tissue Culture System
A model system is described for the mass propagation of Rift Valley fever (RVF) virus, utilizing large-volume fermentor units for suspension culture of tissue cells and the subsequent production of virus. Comparisons between laboratory- and fermentor-scale operations of tissue cell growth gave equivalent results. Cell viability dropped 24 to 30 hr postinfect

17. Immunological responses of mice and cattle to baculovirus-expressed F and H proteins of rinderpest virus: lack of protection in the presence of neutralizing antibody.
Rinderpest is a highly contagious viral disease of ruminants and has greater than 95% morbidity and mortality. The etiological agent, rinderpest virus (RPV), is a member of the family Paramyxoviridae and the genus Morbillivirus. Immune responses to both the hemagglutinin (H) and the fusion (F) antigens of morbilliviruses play an important role in the prevent

18. Identification of a distinct soluble subunit of an intermediate filament protein: tetrameric vimentin from living cells.
Intermediate-sized filaments (IF) are among the most insoluble intracellular protein polymer structures. We have analyzed the small amounts of soluble vimentin, an IF protein, present in cytosol fractions obtained from lysis of cultured cells [rat RVF-SM cells, simian virus 40-transformed human fibroblasts, and human rhabdomyosarcoma (RD line) cells]. The mo
