DEVICE FOR SIMPLY DETECTING RESISTANT MICROORGANISM

PURPOSE:To provide the subject device for readily detecting a microorganism resistant to many agents, comprising microorganism collecting ends to be mutually brought into contact with each other in an integrated way by action of external force, containing an antibiotic and a medium, arranging the antibiotic and the medium in a non-contact way in a container and having long-term shelf stability. CONSTITUTION:In a device for detecting a microorganism by culturing a microorganism in a medium and observing change of the medium, the device consists of a transparent lower tube 1 having an open top and a closed bottom and an upper tube 2 which has a closed top, a lower end closed with a porous plate 3, is used also as a cap to be hermetically engaged with the lower tube 1 and to seal the lower tube 1 and is provided with a glass ampule 4 having sealed the medium between the top and the porous plate 3 at the bottom. The porous plate 3 is provided with an applicator 6 for collecting a microorganism, having the other end extending in the lower tube 1 and a disc chip 5 impregnated with the antibiotic to suppress growth of microorganisms except the resistant microorganism. After a cell is collected by the applicator 6, the glass ampule 2 is broken, the medium is guided to the lower tube 1 and the microorganism is cultured to detect the microorganism by change of the medium.
