Abstract: A novel immunodeficiency virus is disclosed which has the designation MVP-5180/91 (SEQ ID NO:56) and which has been deposited with the European Collection of Animal Cell Cultures (ECACC) under No. V 920 92 318. The characteristic antigens which can be obtained from it and which can be employed for detecting antibodies against retroviruses which are associated with immuno-deficiency diseases are also disclosed, as are the DNA and amino acid sequences of the virus.

Abstract: A novel HIV type O immunodeficiency virus is disclosed which has the designation MVP-2901/94 and which has been deposited with the European Collection of Animal Cell Cultures (ECACC) under No. V 95012601. The characteristic antigens which can be obtained from the virus and which can be employed for detecting antibodies against retroviruses which are associated with immunodeficiency diseases are also disclosed, as are the partial DNA and amino acid sequences of the virus.

Abstract: A lighting and flash device comprises a flash tube with a corresponding ignition device and at least two energy storage device units. The voltage of the energy storage device units is independently adjustable. When the voltage of the energy storage device units is accordingly divided, the resulting color temperature, in practice, is held relatively constant within allowable limits.

Abstract: A lighting fixture which comprises a light reflecting fixture case having a transparent wall disposed next to an opening to provide light outflow, a light source disposed in the fixture case, and a diffuser wall covering the light outflow providing opening of the case and which is attached to the transparent wall and which reaches to at least the outer face of the transparent case wall. Thus the face of the diffuser wall can completely be used as light providing surface. Preferably, the transparent case wall is covered with a thin layer of reflecting and opaque material.
