The present invention provides devices and methods for determining the presence or absence of pathogens in a biological sample and for the concurrent determination of the antimicrobial susceptibility of pathogens present. The devices and methods of the present invention are able to make the determinations without pre-selection of target bacteria. Instead, all organisms from the sample are applied to the device. In wells where one or more antimicrobial agents are present only pathogens resistant to the antimicrobial agent grow. This allows the user to determine the presence of target pathogens and concurrently determine the resistance patterns of the organisms without the need to subculture the organisms. The present invention also provides methods of performing a business service of performing the determinations described above, and kits containing the devices and descriptions of the methods.

La présente invention concerne des dispositifs et des méthodes qui permettent de déterminer la présence ou l'absence d'agents pathogènes dans un prélèvement biologique, et de déterminer de façon concurrente la sensibilité aux antimicrobiens des agents pathogènes présents. Les dispositifs et méthodes de l'invention permettent d'effectuer ces déterminations sans présélection des bactéries cibles. Au lieu de cela, tous les organismes du prélèvement sont pris en compte dans le dispositif. Dans des cupules où un ou plusieurs agents antimicrobiens sont présents, seuls les agents pathogènes résistants aux agents antimicrobiens se développent. Cela permet à l'usager de déterminer la présence d'agents pathogènes cibles et de déterminer de façon concurrente les profils de résistance des organismes, sans nécessité de repiquer les organismes. L'invention concerne en outre des méthodes d'accomplissement d'un service commercial destiné à effectuer les déterminations ci-décrites, des trousses contenant les dispositifs, et des descriptions des méthodes de l'invention.
