Abstract:
A method of determining the presence of microorganisms in a sample comprising:providing a transparent container having a sidewall, a bottom wall, an open top end, and a closure coupled to said open top end, said container containing a microorganism growth medium, wherein said container is made by a molding process from cyclic olefin copolymer, said container having a transparency sufficient to visually detect turbidity in said microorganism growth medium and said microorganism growth medium being substantially free of contamination after storage for at least about one year at about 40Â° C.; adding a sample suspected of containing a microorganism to said transparent container; irradiating said fluorescent sensor with a light source capable of fluorescing said fluorescent sensor; detecting fluorescent light intensity from said fluorescent sensor while irradiating said fluorescent sensor; and comparing said detected fluorescent light intensity with a control and determining the presence of microorganisms in said sample.
