ABSTRACT:
The present invention describes a method and apparatus for detecting bacteria in blood culture bottles with a chemical sensor dissolved directly in the culture medium that (1) introduce a blood specimen, a growth medium, and a soluble chemical sensor dye into a sealable container, (2) agitate the container vigorously so that a froth is generated above the liquid, and (3) monitor the spectroscopic characteristics of the blood culture froth. The spectroscopic characteristics are then analyzed to determine whether bacteria are present in the blood culture bottle.
