Abstract: A method that enables handling whole blood for assays where the whole blood is directly taken from a patient without any prior treatment and being put in a collection tube or other container ready to use for further analysis. The method can enable simple processing of the whole blood while avoiding any clots or aggregates and without damaging white cells in a reproducible and automatable way. The method can furthermore enable an automatic and reproducible pipetting of whole blood cells inside several wells to be tested.

Abstract: A computer-implemented method for detecting a genome sequence in digital form in a genome of a microorganism in digital form, including:—storing, in a computer memory, a set of digital genome sequences of constant length k, or ‘k-mers’, the set being obtained by sliding, at a constant pitch, a window of length k over the genome sequence;—for each k-mer, determining its absence or presence in the genome;—determining that the genome sequence is present in the genome if the percentage of k-mers detected as present in the genome is higher than a predetermined threshold.

Abstract: A method for determining the integrity of at least one complex based on at least one biological sample and at least one matrix, including at least the following steps:—acquiring at least one image,—analyzing the image sent by extracting light intensity values representative of at least one spectral band,—relating the light intensity values to one another to obtain representative spectral data,—determining a state of integrity of the complex by comparing each of the representative spectral data by similarity grouping with a determined similarity threshold,—triggering at least one first alert, by the analysis unit, when the representative data are similar to the first state of integrity or to the second state of integrity.

Abstract: The method for detecting and monitoring a bacterial outbreak includes predicting that a collected bacterial strain and a bacterial strain from a database belong to the bacterial outbreak if their genomic distance is less than a first predetermined threshold, do not belong to the bacterial outbreak if their genomic distance is greater than a second predetermined threshold strictly greater than the first threshold, or may belong to the bacterial outbreak if their genetic distance is in-between. The first threshold is greater than or equal to a third threshold, such that a prediction that two bacterial strains with a genomic distance less than the third threshold belong to the outbreak has maximum specificity. The second threshold is less than or equal to a fourth threshold, such that a prediction that two bacterial strains with a genomic distance greater than the fourth threshold do not belong to the outbreak has maximum sensitivity.
