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.

Method for determining the integrity of a deposit of a complex based on a biological sample and system for carrying out said method

The invention relates to a method for detecting the Gram type and the fermenting character of a bacterial strain, said method comprising: illuminating, in the wavelength range of 390 nm to 900 nm, at least one bacterium from said strain which has a natural electromagnetic response within said range; acquiring, within said range, a light intensity reflected by, or transmitted through, said illuminated bacterium; and determining the Gram type and the fermenting character of the bacterial strain according to the light intensity acquired within said range.

Method and system for identifying the gram type of a bacterium

Method for characterising a microorganism, comprising: —illuminating, in the wavelength range of 390 nm-900 nm, the microorganism having a natural electromagnetic response in said range; —acquiring, in said range, a light intensity reflected by said (or transmitted through said) illuminated microorganism; and —determining the microorganism as being a yeast or a bacterial strain according to the light intensity acquired in said range.

Method for identifying yeast or bacteria from a luminous intensity reflected by, or transmitted through, an illuminated microorganism

A detection of the Gram type of a bacterial strain includes: illumination, in the wavelength range 415 nm-440 nm, of at least one bacterium of said strain having a natural electromagnetic response in said range; acquisition, in the range 415 nm-440 nm, of a light intensity reflected by, or transmitted through, said illuminated bacterium; and determination of the Gram type of the bacterial strain as a function of the light intensity acquired in the range 415 nm-440 nm.
