Résumé dans la langue de publication, traduction non disponible An object of the present invention is to offer a microorganism-detecting apparatus where the microorganism causing a food poisoning can be detected/identified by a simple operation and also a disposal treatment can be conducted safely and surely. Means for achieving the object is as follows: Thus, the apparatus for detecting microorganism as mentioned below is portable and enables us to selectively incubate and detect the microorganism (particularly those which are a cause of food poisoning) without skillfulness and the detecting apparatus containing pathogenic microorganism (such as that which is a cause of food poisoning) can be safely and surely disposed. Said apparatus is characterized in having at least (a) a container (1) for holding a medium which is used for culturing the microorganism to be detected during the period of the incubation of said microorganism; (b) a microorganism-collecting part (6); (c) a means (3) for making possible a process of receiving, in a noncontact manner with the microorganism-collecting part, the medium used for culturing the microorganism to be detected until the incubating stage of the microorganism; and (d) a means (9) for disinfecting the medium after incubation.
