Colorful series with 12 test chambers for the identification of Enterobacteriaceae and other gram-negative and oxidase-negative bacteria. EnteroPluri-Test is a test system with 12 chambers containing special culture media for the identification of Enterobacteriacaeae and other gram-negative and oxidase-negative bacteria. The system allows the simultaneous inoculation of all culture media present in the chambers and the performance of 15 biochemical reactions. The microorganism is identified by evaluating the color change of the different culture media after 18-24 hours of incubation at 36 ± 1 °C and using a numerical code obtained by interpreting the biochemical reaction.
