Abstract: Method for determining the sensitivity of a bacterial strain of interest to a viral strain of bacteriophages, the method comprising: a) preparing a sample, this comprising bringing bacteria, belonging to the bacterial strain of interest, into contact with bacteriophages, each bacteriophage belonging to the same viral strain, the bacteria being either in a liquid medium, or in an agar medium; b) placing the sample between a light source and an image sensor, the light source emitting a light wave in an emission spectral band comprised between 500 nm and 600 nm; c) illuminating the sample using the light source and acquiring at least one image of the sample, with the image sensor, in the emission spectral band, no image-forming optic being placed between the sample and the image sensor; d) on the basis of the acquired images, determining a sensitivity of the bacterial strain of interest to the viral strain.

Abstract: A method for detecting a lytic activity of one or more types of phages or of the activity of one or more antibiotics with respect to a bacterial strain, the method including using a first multiwell plate, each well receiving a sample containing phages or antibiotics, making at least one deposit on a transparent area of a support, the deposit containing bacteria of the bacterial strain, applying the first plate against the support so that each sample in each well comes into contact with the deposit, for each well, determining, using the detection means, the activity or absence of activity of the phage or antibiotic with respect to the bacterial strain, taking into account the intensity of light signals transmitted through each well and/or the variation thereof over time.

Abstract: A method for obtaining an image of a sample includes illuminating the sample using a light source; acquiring, using an image sensor, a first image of the sample, the image being formed in the detection plane, the first image being representative of an exposure light wave propagating, from the sample, to the image sensor, along a first optical path; modifying an optical refractive index, between the image sensor and the sample; acquiring a second image of the sample, the image being representative of the exposure light wave along a second optical path; and implementing an iterative algorithm that combines the first and second images so as to obtain an image of the sample.
