The invention concerns a process for diagnosis of an HIV infection by means of an immunoassay using the specific detection of the p24 antigen of HIV1, HIV1-Sub0 and/or the p26 antigen of HIV2, at least one antibody against the env region of HIV1, HIV1-Sub0 and/or of HIV2 and at least one antibody against the pol and/or gag region of HIV1, HIV1-Sub0 and/or HIV2, reagent kits and test strips suitable for diagnostic procedure as well as monoclonal antibodies against p24 and their use.

Method for simultaneous detection of HIV antigens and HIV antibodies

The claimed invention relates to an HIV-1 group O envelope antigen comprising SEQ ID NO: 100, and the use of said antigen as a reagent in the diagnosis of HIV-1 group O infection, and a kit therefore.

HIV-1 group O antigens and uses thereof

The present invention relates to an isolated 17-kDa Brucclla antigen characterized by an amino acid sequence having at least 60% homology, preferably at least 70% homology, more preferably having at least 80% homology to the amino acid sequence as shown in SEQ ID No. 1 or 2, with said antigen being specifically recognized by sera from Brucella field infected individuals, more particulary an antigen characterized by the amino acid sequence as shown in SEQ ID No. 1 or 2. The invention also relates to recombinantly produced 17 kDa Brucella antigen, nucleic acids coding for the same and the use thereof in diagnostic and prophylactic methods and kits.

17-KDA Brucella abortus antigen, recombinant polypeptides, nucleic acids coding for the same and use thereof in diagnostic and prophylactic methods and kits

Described is a new variety of retrovirus designated HIV-3, also known as HIV-1 subtype O, samples of which are deposited in the European Collection of Animal Cell Cultures (ECACC) under V88060301. Further described are variants of the virus.

HIV-3 retrovirus and its use

The present invention relates to isolated and pure,antigenic fragments, recombinant polypeptides, nucleic acids encoding them, primers and probes derived from the same, as well as the use of these polypeptides, nucleic acids, primers and probes in methods and kits for the diagnosis and prevention of,infection in mammals (humans and animals).

Toxoplasma gondii antigen Tg20

Described is a new variety of retrovirus designated HIV-3, samples of which are deposited in the European Collection of Animal Cell Cultures (ECACC) under V88060301. Further described are antigens obtained from the virus, particularly proteins p12, p16, p25 and glycoproteins gp41 and gp120 to be used in the diagnosis of ARC or AIDS caused by HIV-3. Immunogenic compositions to be used as vaccines contain an envelope glycoprotein of HIV-3 such as gp41 or gp120.

Further described are antigens obtained from the virus, particularly proteins p12, p16, p25 and glycoproteins gp41 and gp120 to be used in the diagnosis of ARC or AIDS caused by HIV-3. The methods to detect antibodies against HIV-3 retrovirus in a biological fluid involve contacting the suspect body fluid with a composition containing one or more of the proteins or glycoproteins of HIV-3 or with a lysate of the virus, or with an antigen possessing epitopes common to HIV-3, and detecting the immunological conjugate formed between the anti-HIV-3 antibodies and the antigen(s) used.
