  • Patent number: 9023602
    Abstract: The present invention relates to a method for determining the presence of a cyst nematode in a sample comprising the steps of: providing a pair of bidirectional oligonucleotide primers or an oligonucleotide probe that hybridizes specifically, under stringent hybridization conditions, to a nucleic acid sequence encoding the SSU rRNA or LSU rRNA, or the complement or transcript thereof, of a sub genus-cluster of nematodes, said subgenus-cluster comprising cyst nematodes belonging to at least one species of nematode, and wherein said primers or probe do not hybridize to a nucleic acid sequence encoding the LSU rRNA, or the complement or transcript thereof, of cyst nematodes not part of said subgenus-cluster of cyst nematodes; providing a sample in which the presence of the cyst nematode is to be detected, and performing a nucleic acid detection assay on said sample using said pair of bidirectional oligonucleotide primers or said oligonucleotide probe.

  • Patent number: 7857126
    Abstract: The invention relates to a guide for supporting a displaceable object, comprising: a plastic guide profile (1, 7, 16, 30) and a support structure (6, 12, 18, 32) supporting the guide profile, characterized in that the guide profile is engaged at least at two spaced-apart positions by the support structure, at least one engaging position of which consists of a free support (4, 5, 10, 11, 13, 14, 33, 34) of the guide profile on the support structure such that the freely supporting side of the guide profile is displaceable relative to the support structure. The invention also relates to a device (21) for conditioning products displaceable along a guide track (22).

  • Publication number: 20100081133
    Abstract: The present invention relates to a method of testing a sample for the presence of a Meloidogyne nematode, said method comprising the step of analyzing the nucleic acid in said sample for the presence of an rRNA gene of a Meloidogyne nematode, or the transcription product thereof, or a fragment thereof, comprising at least one single nucleotide polymorphism (SNP) and/or at least one oligonucleotide polymorphism (OP) that is essentially unique on phylum level to a specific group of Meloidogyne nematode species of which said Meloidogyne nematode is a member, wherein said step of analyzing said nucleic acid involves a nucleic acid hybridization assay, and wherein said group comprises (a) the species M. chitwoodi, M. fallax and M. minor; (b) the species M. naasi, M. oryzae and M. graminicola; (c) the species M. hapla, M. microtyla, M. ardenensis, M. maritime and M. duytsi; and/or (d) the species M. incognita, M. arenaria and M. jaυanica.
