E. Coli Strips
E. Coli Strips
Rapid diagnostic test for tryptophan hydrolysis by E. coli.
E. Coli Strips is based on the indole spot test of Vracko and Sherris. Certain bacteria, most notably E. coli will break down tryptophan to produce indole, pyruvate and ammonia. The indole molecule is detected by its chemical reaction with p-dimethylamino-cinnamaldehyde (DMACA) impregnated in the test strip, which produces a distinct coloured compound. DCMACA reagent is chosen since it is more sensitive than traditional Ehrlich’s or Kovac’s reagents, and allows more rapid detection of indole. E. Coli Strips are a useful rapid test for E. coli isolated from urine samples. This organism accounts for up to 80% of urinary tract infections, and can be quickly confirmed using E. Coli Strips.
Description: Paper strip impregnated with p-dimethylamino-cinnamaldehyde (DMACA).
Method of use: Using wire or plastic loop, touch 2 or 3 colonies of test organism on agar medium. Smear organism onto test zone on the strip. Positive result is indicated within 30 seconds by smeared area turning green-brown.
