    Abstract: The invention relates to a process for generating infectious Newcastle disease virus (NDV) entirely from cloned full-length cDNA and to the use of vaccines and diagnostic assays generated with and derived from the process. The process offers the possibility to modify the NDV genome by means of genetic modification and allows for the introduction of mutations, deletions and/or insertions. The process can be used to modify the virulence of NDV, thus generating new attenuated live vaccines with enhanced properties. The process can be used to modify the antigenic make-up of NDV, to allow the generation of live NDV marker vaccines that can be serologically distinguished from NDV field strains.

    Abstract: This invention relates to a method for producing virus RNA polymerases of RNA viruses, more specifically, virus RNA polymerases of RNA viruses free of virus genomic RNA. The methods described in this invention includes the procedures for preparation of cDNAs for the genes for the component proteins of RNA polymerase of an RNA virus, incorporation of the cDNA into baculovirus genome to construct recombinant virus, and the infection of insect cells with the recombinant virus to express RNA polymerase. In this method, it is recommended that all species of the recombinant viruses, each of which is designed for expressing each of the above-mentioned component protein genes of RNA polymerase, are coinfected into insect cells. Thus, cDNA is prepared for each of the component proteins of RNA polymerase and incorporated into baculovirus genome to construct recombinant virus for independently expressing the corresponding protein. In addition, the RNA viruses described above include influenza virus especially. In this method, RNA polymerase may be tagged to facilitate the subsequent purification. Furthermore, the tagged RNA polymerase described above may be purified using an adsorbent to trap the RNA polymerase at the tag. Another subject matter of this invention is to artificially prepare a complex of the component proteins of RNA polymerase of an RNA virus, or, in other words, to prepare RNA polymerase free from RNA virus genomic RNA. The RNA viruses described here include influenza virus, and the component proteins of RNA polymerase include PA, PB1 and PB2.

    Abstract: The invention provides a process for the selection of HIV-1 subtype (clade) C isolates, selected HIV-1 subtype C isolates, their genes and modifications and derivatives thereof for use in prophylactic and therapeutic vaccines to produce proteins and polypeptides for the purpose of eliciting protection against HIV infection or disease. The process for the selection of HIV subtype isolates comprises the steps of isolating viruses from recently infected subjects; generating a consensus sequence for at least part of at least one HIV gene by identifying the most common codon or amino acid among the isolated viruses; and selecting the isolated virus or viruses with a high sequence identity to the consensus sequence. HIV-1 subtype C isolates, designated Du422, Du 151 and Du 179 (assigned Accession Numbers 01032114, 00072724 and 00072725, respectively, by the European Collection of Cell Cultures) are also provided.
