Abstract: An object is to obtain not only information indicating whether or not a drug is effective against bacteria but also additional information about an effective drug. An examination method includes a sample preparation step of obtaining a plurality of samples by bringing drugs of a plurality of types into contact with bacteria, and an image capturing step of capturing an image of each sample. The examination method includes a step of determining efficacy of the drug based on each sample image obtained in the image capturing step, and a step of obtaining drug susceptibility information by comparing a plurality of sample images including the drug determined as being effective, in accordance with a prescribed criterion.

Abstract: One object is to reduce the time required for focusing. When an image capturing condition is not stored (when image capturing of an observation area is performed for the first time), an examination device performs an autofocus process, obtains a focus position where a microscope camera is in focus on the observation area, and stores the obtained focus position in a storage device. In contrast, when the image capturing condition is stored (when image capturing of the observation area is performed for the second and subsequent times), the examination device captures an image of the observation area by reading out the focus position from the storage device and setting a focal point of the microscope camera at the read-out focus position.

Abstract: A testing method using a micro flow path device configured for a test liquid containing a specimen to be brought into contact with a drug therein and for a test on an action of the drug on the specimen includes: preparing the micro flow path device including: a plurality of micro flow paths, first and second openings which are disposed at both ends of each of the plurality of micro flow paths and communicate with an outside, a storage unit which is provided in each of the plurality of micro flow paths and stores the drug, and a gas-permeable membrane covering the first opening; applying a fluid pressure higher than an external pressure to the test liquid through the second opening from a syringe pump connected to the second opening to pressure-feed the test liquid to the storage unit; and observing a target region set in the micro flow path.
