Abstract: A method for discriminating between live and dead microbes in a sample, by discriminating between transcriptionally-active and inert microbial nucleic acid sequences in the sample. In particular, the method is based on the comparison of levels of nucleotide substitution in a sample cultured in presence of an RNA-labelling agent. Also, a diagnosis method of microbial infections in a subject; and methods of assessing the risk of contamination of a sample, implementing the method for discriminating between live and dead microbes in a sample.

Abstract: The present invention provides compositions, kits, and method for determining the levels of expression of human polyoma or papillomavirus species and RNA transcripts. These levels can be used for the prognosis of risk of developing virally-induced cancers. The ratio (R) between early and late transcripts is indicative of HPV infections associated with higher risk of developing genital neoplasia and cancer.

Abstract: The present invention relates to the use of the measure of anelloviral load for the determination of immunosuppression. More precisely, the present invention provides a method for characterizing the immunosuppressed or non-immunosuppressed status of a subject, comprising the steps of determining the anelloviral load from a biological sample of the said subject, and determining from the said comparison the immunosuppressed or non-immunosuppressed status. The determination of the immunosuppressed status of the subject can then be used to design or adapt a therapeutic treatment.

Abstract: The present invention relates to HGyV, a human gyrovirus related to the chicken anemia virus (CAV). The present invention also relates to a new proteins encoded by HGyV, which proteins display some homology to CAV proteins. Among these new proteins, H-apoptin is of particular interest as it is herein found for the first time in a human virus and can be used for treating cancer. Also provided are methods for detecting the HGyV virus in a subject.
