Tissue Tropism and Target Cells of NSs-Deleted Rift Valley Fever Virus in Live Immunodeficient Mice
Rift Valley fever, caused by a member of the Bunyaviridae family, has spread during recent years to most sub-Saharan African countries, in Egypt and in the Arabian peninsula. The virus can be transmitted by insect vectors or by direct contacts with infectious tissues. The analysis of virus replication and dissemination in laboratory animals has been hampered by the need to euthanize sufficient numbers of animals and to assay appropriate organs at various time points after infection to evaluate the viral replication. By following the bioluminescence and fluorescence of Rift Valley fever viruses expressing light reporters, we were able to track the real-time dissemination of the viruses in live immunodeficient mice. We showed that the first infected organs were the thymus, spleen and liver, but the liver rapidly became the main location of viral replication. Phagocytes also appeared as important targets, and their systemic depletion by use of clodronate liposomes decreased the number of viruses in the blood, delayed the viral dissemination and prolonged the survival of the infected mice
A Purity Monitoring System for the H1 Liquid Argon Calorimeter
The ionization probes used for monitoring the liquid argon purity in the H1
calorimeter are described and results of their operation in tests at CERN and
during the period 1992 to the end of 1998 at HERA are given. The high
sensitivity of the charge measurements leads to refined charge collection
models, and to the observation of a variation of the ionization yield of our
electron sources with temperature.Comment: 26 pages, 14 figure
