Zusammenfassung:	A bacteriological investigation method for identifying a bacterial load and selecting the most effective antibiotic for therapeutic treatment, comprising, measuring a light scattering reading of a suspension formed from a liquid culture medium or eugonic medium in which a biological sample is inoculated, determining a turbidity according to the McFarland standard based on the light scattering reading, wherein the turbidity is repeatedly determined directly from a suspension of the sample that is analyzed during an exponential growth phase of a bacteria in the sample until a desired McFarland standard threshold is reached. La présente invention concerne un procédé de recherche de bactéries dans un échantillon biologique consistant à effectuer une mesure de la diffusion de la lumière afin de déterminer la turbidité selon la norme McFarland d'une suspension formée à partir d'un moyen de culture liquide ou d'un milieu eugonique dans lequel l'échantillon biologique a été inoculé, et dans lequel la turbidité est mesurée en continu directement à partir de la suspension de l'échantillon analysé durant l'étape de croissance des bactéries, jusqu'à ce qu'un seuil de turbidité déterminé soit atteint, exprimé selon la norme McFarland.
