A biomérieux internal investigation was conducted for a twice misidentified enterooccus gallinarum cap survey sample, as enterococcus casseliflavus (99%) in association with vitek® 2 gp id test kit.The customer and the reconstituted internal cap strains were subcultured to individual organism suspensions and each was tested with two gp cards from the customer lot and a random lot.The api 20 strep was also performed.For the customer's cap strain, three of the four gp cards tested resulted in low discrimination calls of e.Casseliflavus/e.Gallinarum.The remaining card gave an excellent identification of enterococcus gallinarum.For the internal cap strain, three of the four gp cards tested resulted in low discrimination calls of e.Casseliflavus/e.Gallinarum.The remaining card gave an excellent identification of enterococcus gallinarum.Neither of the two isolates demonstrated yellow pigmentation and both tested hip positive on the api 20 strep test kit, resulting in an identification of e.Gallinarum.The investigation concluded the vitek® 2 gp id cards are performing as expected.
