A cartridge for a bacteria screening device for detecting and recording the existence of bacteria and other microorganisms in a gaseous medium, such as a hospital operating room atmosphere, arranged to continuously or intermittently expose active culture media to a flow of the gaseous medium to impinge the bacteria and other microorganisms thereon and to thereafter incubate the exposed portions of the culture medium for detection and recording purposes. In the bacteria screening device, different active culture media, responsive to different bacteria, are on opposite surfaces of a strip mounted on supply and take up reels in an enclosed cartridge having apertures forming opposed limited exposure areas for the two sides of the strip. Interleaved with the strip carrying the culture media is a separating strip to prevent contact of exposed surfaces of culture media. The cartridge, designed to contain sufficient culture media for the monitored period of time, e. g.

A bacteria screening device for detecting and recording the existence of microorganisms in a gaseous medium. The device is arranged to continuously or intermittently expose active culture media, contained on a strip which is mounted on supply and uptake reels, to a flow of the gaseous medium. The exposed culture media is then incubated to record the existence of microorganisms. The supply and uptake reels are contained in a removable cartridge which has a window to permit exposure of the culture media containing strip.
