ABSTRACT Transmission of Tomato spotted wilt virus (TSWV) is dependent on virus uptake in the midgut prior to virus movement to the salivary glands. Replication of TSWV in the alimentary canal of tobacco thrips (TT, Frankliniella fusca) and western flower thrips (WFT, F. occidentalis) was investigated by immunolocalization of the nonstructural protein (NSs) encoded by the small RNA of TSWV and ...

Compound A3 was identified in a high-throughput screen for inhibitors of influenza virus replication. It displays broad-spectrum antiviral activity, and at noncytotoxic concentrations it is shown to inhibit the replication of negative-sense RNA viruses (influenza viruses A and B, Newcastle disease virus, and vesicular stomatitis virus), positive-sense RNA viruses (Sindbis virus, hepatitis C vir...

CD8+ (suppressor/cytotoxic) lymphocytes block replication of HIV-1 or the simian immunodeficiency virus of macaques (SIVmac) in PBL of infected individuals. We now show that these CD8+ lymphocytes undergo clonal expansion in vivo after AIDS virus infection of the individual, suggesting they may be antigen-specific T cells. These CD8+ cells block replication of virus in autologous but not MHC cl...

background previous studies using cell culture systems for the replication of hepatitis c virus have opened new research dimensions, and paved the ways for further and detailed studies of the virus in vitro. objectives the purpose of the present study was to cultivate hepatitis c virus in a cell culture system and evaluate viral amplification. materials and methods in order to propagate hepatit...

In this study, the immunogenicity of a rabies vaccine that was used in one of the Isfahan cattle farms is reported. This vaccine was produced by replication of the Pasteur virus (PV) strain on BHK-21 monolayer cell culture. The virus suspension was inactivated by ß-propiolactone treatment and the harvested pool showed sterility and safety. Thus, the obtained vaccine was tested on mice and a sat...
