VITEK® 2 GRAM-NEGATIVE IDENTIFICATION TEST KIT

Additional Manufacturer Narrative

BIOMÉRIEUX INVESTIGATION WAS CONDUCTED. THE ISOLATES (2) WERE SUBCULTURED AND TESTING INCLUDED THE FOLLOWING. ISOLATE 1: GN ID CARD FROM THE SAME LOT AS THAT TESTED BY THE CUSTOMER - VERY GOOD IDENTIFICATION CALLS OF KLEB PNEUMONIAE SSP OZAENAE. GN ID CARD FROM A RANDOM LOT - VERY GOOD IDENTIFICATION CALLS OF KLEB PNEUMONIAE SSP OZAENAE. API® 20E - LOW DISCRIMINATION CALL BETWEEN ENT CLOACAE (54.9%) AND KLEB PNEUMONIAE (31.5%). 16S SEQUENCING - IDENTIFICATION AS KLEBSIELLA PNEUMONIAE. VITEK® MS - IDENTIFICATION AS KLEBSIELLA PNEUMONIAE. ISOLATE 2: GN ID CARD FROM THE SAME LOT AS THAT TESTED BY THE CUSTOMER - UNIDENTIFIED ORGANISM GN ID CARD FROM A RANDOM LOT - IDENTIFICATION OF PANTOEA AGGLOMERANS. API® 20E - DOUBTFUL PROFILE WITH THE CHOICES INCLUDING KLEBSIELLA PNEUMONIAE (27.2%) / PANTOEA 1(18.5%) / PSEUDOMONAS LUTEOLA (18.4%) / PANTOEA 3 (18.4%). 16S SEQUENCING - KLEBSIELLA PNEUMONIAE. REVIEW OF THE PANTOEA DATA AGAINST THE EXPECTED REACTIONS FOR KLEBSIELLA PNEUMONIAE SHOW THE PANTOEA DATA TO HAVE 19 ATYPICAL NEGATIVE REACTIONS. THIS BEHAVIOR SUGGESTS VERY SLOW ORGANISM GROWTH WHICH IS NOT CONDUCIVE TO PHENOTYPIC AST TESTING METHODS. BOTH 16S SEQUENCING AND VITEK® MS USE GENETIC MEASUREMENT TECHNIQUES AND ARE MORE CONDUCIVE TO TESTING CERTAIN SLOWER-GROWTH ORGANISMS. THE INVESTIGATION DID NOT REPRODUCE THE CUSTOMER'S IDENTIFICATION OF PSEUDOMONAS LUTEOLA. THE VITEK® 2 GN ID CARDS ARE PERFORMING IN ACCORDANCE WITH SPECIFICATIONS.
