With the rise of antibiotic resistance, phage therapy is seen as a promising alternative to cure infection to multiresistant bacteria strains. However, phage susceptibility tests currently carried out are time-consuming and are not compliant with the automated environment of hospital laboratories. In this work, we present a method for phage susceptibility testing through optical density measurement with the use of lensless imaging technique. Using a 3.3 cm2 area CANON sensor and a custom test card, we are able to simultaneously monitor the bacterial growth or inhibition of multiple bacterial/phage samples and to provide reliable results in less than 4 hour.
