Abstract:
Provided herein is a method of purification of non-enveloped or pseudo-enveloped virus produced in vitro using a composition with at least one detergent. Also provided are a method of purification can use multiple detergents, and a method of determining the presence and/or level of a non-enveloped or pseudo-enveloped virus in a sample.
Abstract:
The present invention provides an in vitro method for concentrating infectious pathogens found in a biological sample obtained from an individual who is suspected of being infected with the pathogens. Provided herein is also an in vitro method for reducing or eliminating blood cells from a sample obtained from an individual suspected to being infected with an infectious pathogen. The present invention also provides a method for diagnosing malaria and a method for determining if an individual is infected with a pathogen. Provided herein is also a concentrator and a kit for use with the methods.
Abstract:
The invention relates to an in vitro method for determining in an isolated sample of a subject the presence of one or more Human Hepatitis C Virus (HCV) sequence variants comprising reverse transcription and amplifying HCV RNAs molecules using specific sets of primers allowing the amplification of the HCV regions named 5'-UTR-Core and NS5B. The method includes an step for purifying the amplified regions and a sequencing step of the amplified fragments. The invention also includes specific oligonucleotides than are used as primers in the method, as well as kits including one or more of these oligonucleotides as sets of primers.
Abstract:
Disclosed are methods for detecting a minority genotype of a target nucleic acid. The disclosed method generally includes the steps of (a) deep sequencing at least a portion of the target nucleic acid; (b) using the deep sequencing results of (a) to detect the presence of variant nucleobases at one or more nucleotide reference positions within the target nucleic acid; (c) using the variant detection results generated in step (b) to perform a statistical analysis of whether the variants are significant; and (d) using the variant detection and variant significance results generated in steps (b) and (c) to perform a statistical analysis of whether a subset of sequences together exhibit a common set of significant variants.
Abstract:
The present invention relates to molecular approaches to the production of nucleic acid sequences, which comprises the genome of infectious hepatitis C virus. In particular, invention provides nucleic acid sequences which comprise the genomes of infectious hepatitis C viruses of either genotype 3a (strain S52) or genotype 4a (strain ED43). The invention therefore relates to the use of the nucleic acid sequences and polypeptides encoded by all or part of the sequences in the development of vaccines and diagnostic assays for HCV and in the development of screening assays for the identification of antiviral agents for HCV. The invention therefore also relates to the use of viral particles derived from laboratory animals infected with S52 and ED43 viruses.
Abstract:
The present invention relates to nucleic acid sequences that encode hepatitis C viruses (HCV) of genotype 2b that are useful in the fundamental research of HCV as well as in the search of a vaccine against HCV. In particular the present invention relates to nucleic acid sequences that comprises HCVs, which are capable of expressing said virus when transfected into cells and are capable of infectivity in vivo.
