Abstract: The present invention provides improved tests for the detection of methicillin-resistant Staphylococcus aureus. The tests are particularly useful for eliminating false positive results due to the presence of a mixed bacterial population in patient samples.

Abstract: A method for lysing prokaryotic or eukaryotic cells, or for simultaneous lysis of both, which includes at least three of the following: a mass of active, small-diameter beads corresponding to 50% or less than a mass of active, larger-diameter beads, and/or a total mass of lysing beads (consisting of a single type of bead or a mixture of smaller and larger beads) corresponding to between 50 and 100% of the total mass of the processed biological sample, and/or a lysis time of from 10 to 20 minutes, and/or seven or less non-lysing glass beads to drive the movement of the lysing beads, and/or from five to fifteen non-lysing iron beads to drive the movement of the lysing beads, depending on whether sonication, mechanical vortex centrifugation or magnetic vortex centrifugation is used.

Abstract: The present invention relates to a method for detecting and/or identifying bacteria of the genus Staphylococcus, comprising the following steps: A. the nucleic acid material of the bacteria of the genus Staphylococcus is extracted, B. at least one target sequence of the nucleic acid material of the bacteria of the genus Staphylococcus is amplified using at least one amplification primer comprising at least 10 nucleotide motifs of SEQ ID No. 1 and/or at least one amplification primer comprising at least 10 nucleotide motifs of SEQ ID No. 2, in order to obtain amplicons of the target sequence, C. the presence of bacteria of the genus Staphylococcus is determined by detecting said amplicons.

Abstract: The invention concerns a lysis method for a biological sample comprising at least one micro-organism of the bacteria type, for releasing a nucleic material of interest belonging to said micro-organism, which consists in: providing in a container a biological sample in liquid medium; providing in said container at least one particulate material, relatively hard, and substantially inert with respect to the nucleic material; submitting the biological sample and particulate material mixture to a movement. The invention is characterised in that in combination, the selected movement is of the vortex type, and satisfies the following conditions: the particulate material consists of beads with diameter between 90 and 150 &mgr;m; and the apparent volume of the beads (Vb) and the volume of the liquid sample (Ve) are linked by the relationship Ve=&agr;. Vb, with &agr; ranging between 1.4 and 10 when the container is tubular in shape, and &agr; is not more than 2.
