Provided is a test apparatus in which a test for bacterial identification or antimicrobial susceptibility can be promptly determined. A division state of bacteria is monitored by performing microscopic observation of shapes and the number of the bacteria in each of wells in a culture plate for bacterial identification culture or an antimicrobial susceptibility test, and it is determined whether or not the bacteria grow in a stage shifted from an induction phase to a logarithmic phase, with reference to an image obtained through microscopic observation. In addition, determination performed based on turbidity in the related art may be combined with determination performed based on microscopic observation in which change and the like in the shapes of the bacteria are monitored. Accordingly, it is possible to realize a highly accurate test result.

Systems and methods for assessing a microbial characteristic within a growing medium. Such a system assesses one or more microbial characteristics, such as biomass and/or microbial activity, within a growing medium, such as soil. Electrical properties of a microbially degradable material in contact with the growing medium are measured. The measurements are used to determine the microbial characteristic(s) based at least partly on degradation of the microbially degradable material.

According to one embodiment, a monitoring device includes a detector unit including an image transfer element comprising an incident surface which allows light to enter from a light-transmissive base material on which a microbody is placed and an emission surface which emits the light entering from the incident surface, which transfers two-dimensional image data of the microbody to a semiconductor optical sensor, and the semiconductor optical sensor which receives light from the emission surface.

An apparatus, that relates to the field of in vitro fertilization, is provided for the combined incubation and vitrification of a biological material. The apparatus can be configured to allow for automatic incubation and vitrification of a viable biological material. Thereby predetermined protocols for handling the biological material can be performed precisely and accurately thus avoiding errors and deviations from the intended protocol, as caused by manual human intervention.

The invention relates to a method, to a device, and to a system for the automated determination of optical densities or of the change in optical densities of reaction mixtures in shaken reactors during shaking operation. Methods and devices currently used therefor are often unreliable, are susceptible to environmental and process factors, or require interruptions to the shaking operation that impair the process control. The problem addressed by the invention is that of specifying a method and a device for the automated determination of optical densities or of the change in optical densities of reaction mixtures in shaken reactors during shaking operation that operate reliably under various environmental and process conditions. This problem is solved by means of a new measurement method, wherein the reaction mixture distribution, which periodically fluctuates because of the shaking action, is used to record measurement points (20/21) of transmission/scattered-light measurements, which measurement points fluctuate periodically as a result of shaking. All measurement points (20/21) of a measurement operation are combined into a measurement series (34), from which the optical density and/or the change in the optical density, and other process parameters, can be determined with high reliability by means of suitable mathematical methods. The invention is suitable in particular for biotechnological, pharmaceutical, chemical, and biochemical screening and optimization and process-monitoring applications.

The invention provides a technology for promptly determining bacterial identification or an antimicrobial susceptibility testing. In the invention, first, a state where the bacteria are divided is monitored by performing microscopic observation with respect to the shape or the number of bacteria in each of wells of a culture plate for bacterial identification culture or the antimicrobial susceptibility testing. In addition, the shape, the number or the area of the bacteria are interpreted from the image obtained by the microscopic observation whether or not the bacteria proliferate at a stage from an induction phase to a logarithmic phase, and the time-dependent changes thereof are made into a graph. From the graph, it is determined whether or not the bacteria proliferate for each measurement, the determination results are displayed on the screen, and accordingly, the result of the antimicrobial susceptibility is provided every time when the measurement is performed (FIG. 12).

Among other things, motility of at least one individual microorganism or a change in motility of at least one individual microorganism or both is or are characterized. The characterized motility or change in motility is used to detect the presence or count of the at least one individual microorganism, or determine the identity of a species or strain of the at least one individual microorganism, or determine a susceptibility of the at least one individual microorganism to one or more antibiotics or other antimicrobials.
