Abstract

Abstract A device for making a culture of micro-organisms has an elongated member which advantageously supports a culture medium on each of two opposite flat faces. A container having an open end is provided for the elongated member. A brush mounted in the container contacts the elongated member intermediate its ends. The open end of the container has removable means to seal it. In a typical operation, the elongated member is removed from the container and the end thereof brought into contact with the area of the patient suspected of having micro-organsims. On returning the elongated member to the container it passes the brush which wipes along the member to brush the inoculum from the end along the culture medium. Advantageously, the container has a guide member to guide the elongated member and restrict its movement toward the interior surfaces of the container. Preferably the brush forms a part of the guide member and the elongated member has a plug adapted to form a seal with the guide member to permit the withdrawal of the elongated member from the container either independently of the guide member or together with the guide member.
