Abstract: DNA probes for detecting the presence of Helicobacter pylori are provided. These isolated, purified oligonucleotide probes are useful in assays for the specific detection of Helicobacter pylori because they specifically hybridize to the DNA of H. pylori.
Abstract: The invention relates to a process for genotyping any HCV isolate present in a biological sample, previously identified as being HCV positive, and for classifying said isolate according to the percentage of homology with other HCV isolates, comprising the steps of:
contacting said sample in which the ribonucleotides or deoxyribonucleotides have been made accessible, if need be, under suitable denaturation, with at least one probe from about 10 to about 40 nucleotides, with said probe being liable to hybridize to a region being in the domain extending from nucleotide at position −291 to nucleotide at position −66 of the 5′ untranslated region of one of the HCV isolates represented by their cDNA sequences, with said numbering of position beginning with the first ATG codon of the open reading frame encoding the HCV polyprotein, or with said probe being complementary to the above-defined probes,
detecting the complexes possibly formed between said probe and the nucleotide sequence of the HCV i

Abstract: A novel gene encoding a 37 kDa outer membrane protein from Campylobacter coli M275 has been cloned and sequenced. This protein has been named CadF and is expressed in a large number of clinical isolates of Campylobacter species. The invention also provides assays for detecting the presence of pathogenic Campylobacter species based on the antibody-based detection of CadF, or the polymerase chain reaction (PCR)-based amplification of a segment of the C. coli cadF gene.

Abstract: Methods for identifying novel secreted mammalian proteins in mammalian host cells are described. Reporter polypeptides which allow detection of signal sequences by growth selection or by enzymatic activity are also described.
Abstract: The present invention relates to methods for detecting a predisposition or susceptibility to prostate cancer in an individual using microsatellite markers. These markers are located on chromosomes 1, 2, 4, 5, 11 and 13.
Abstract: The invention provides a method and materials for analyzing the frequency of sequences in a population of polynucleotides, such as a cDNA library. A population of restriction fragments is formed which is inserted into vectors which allow segments to be removed from each end of the inserted fragments. The segments from each restriction fragment are ligated together to form a pair of segments which serves as a tag for the restriction fragment, and the polynucleotide from which the fragment is derived. Pairs of segments are excised from the vectors and ligated to form concatemers which are cloned and sequenced. A tabulation of the sequences of pairs provides a frequency distribution of sequences in the population.
Abstract: The present invention is directed to methods of detecting the presence of a bipolar mood disorder susceptibility locus in an individual, comprising analyzing a sample of DNA for the presence of a DNA polymorphism on the long arm of chromosome 18 between markers D18S469 and D18S554, wherein the DNA polymorphism is associated with a form of bipolar mood disorder. The invention for the first time provides strong evidence of a susceptibility gene for bipolar mood disorder that is located in the 18q22-q23 region of the long arm of chromosome 18. The disclosure describes the use of linkage analysis and genetic markers in this 18q22-q23 region to fine map the region and the use of genetic markers to genetically diagnose (genotype) bipolar mood disorder in individuals, to confirm phenotypic diagnoses of bipolar mood disorder, to determine appropriate treatments for patients with particular genotypic subtypes.

Abstract: Methods of diagnosing primary congenital glaucoma, by detecting particular mutations in a human cytochrome P4501B1 (CYP1B1) gene, are disclosed. Methods include hybridization analysis, such as Southern or Northern analysis, which use hybridization of a mutant nucleic acid probe to the CYP1B1 gene; direct mutation analysis by restriction digest; sequencing of the CYP1B1 gene; hybridization of an allele-specific oligonucleotide with amplified genomic DNA; or identification of the presence of mutant proteins encoded by the CYP1B1 gene.
