Device for bacteria classification and pretreatment device for bacteria test

Abstract

When automatically classified results are different from judgment of a laboratory technician, the laboratory technician has to reselect the bacterial colonies one-by-one to be a pickup colony through watching the displayed image. To get rid of the inconvenience, provided is a pretreatment device for a bacteria test comprising: a specification unit by which an operator instructs to specify the number of bacterial colonies and the increased / decreased number of the bacterial colonies to be displayed; and a display unit for displaying classification results obtained following the operator's instruction. The pretreatment device for a bacteria test facilitates the automatically classified results to be brought close to the judgment of the laboratory technician, resulting in the saving of the time required for checking the appropriate bacterial colonies for the pickup colony.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a device for imaging multiple species of bacterial colonies, mixedly cultivated on a culture medium, especially, in a petri dish, and classifying the bacterial colonies into a pickup colony based on the image of the bacterial colonies. The device is applied to a pretreatment of a diagnostic sample for a bacteria test such as infection or antibacterial sensitivity test diagnoses.BACKGROUND OF THE INVENTION[0002]In the infection therapy, the processes of identifying infecting bacteria, rapidly measuring sensitivity of a patient against antibiotics, and determining an antibiotic to make a treatment plan, are important for the appropriate antibiotics treatment.[0003]In a general procedure, the following flow is performed including the processes of: applying a submitted sample to a culture medium and cultivating bacteria; preparing a bacterial suspension by picking up bacterial colonies thus formed and suspending the bacterial ...

Benefits of technology

[0022]The devices of the present invention facilitate the automatically classified results of the bacterial colonies in the petri dish for picking up a colony or the like to be brought close to the judgment of the laboratory technician, thereby allowing the operation of checking the appropriate pickup colony to be easily performed. Particularly, when the bacteria species in the petri dish are almost determined, the number of the bacteria species may be specified in advance. This enables a laboratory technician to reduce a load of the checking operation for the pickup colony, thereby to improve the throughput of the pretreatment for a bacteria test. Further, under the condition of the same classification number, the number of the bacterial colonies to be a candidate of the pickup colony may be increased or decreased. This allows a collection of sufficient amounts of bacteria or a collection of only absolute bacteria to be easily instructed. Therefore, it becomes possible to omit the time for increasing the number of the bacterial colonies consumed by recultivating the colonies again, and improve the reliability of the bacterial colonies to be collected. Moreover, the combinational storage of both classification results in bacterial colonies modulated by the aforementioned operation and classification conditions may secure the traceability of the identification / drug sensitivity test.

Problems solved by technology

When the addition of the bacterial colonies is needed, it is necessary to put the sample in the incubator again and wait for the growth of the bacteria, resulting in the requirement of a complicated operation and time.
