ABSTRACT:
An instrument and a sealable vessel for detecting the presence of microorganisms in a specimen, the vessel containing a liquid culture medium communicating with a sensor means containing an indicator medium therein. Changes in the indicator medium resulting from pH change or change in CO.sub.2 concentration in the medium are detected from outside the vessel.
