[Comparative study of various API galeries for the identification of gram negative bacteria].
116 strains of Gram negative bacteria were identified with the use of API ATB 32 GN and Rapid 20 E galeries, in order to evaluate their performance as compared with API 20 E or API NE galeries used as reference. The identification concur (bacterial genus and species) in approximately 80 per cent of the cases. There are only 2 major discrepancies with ABT 32 GN galleries and only one with Rapid 20 E. In other cases, the profile that is obtained only permits identification of the genus but without a sufficient differentiation, requiring a study of additional characteristics or repetition of the test. These galeries enable to solve most routine diagnosis problems due to Gram negative bacteria, with the advantage of Rapid (Rapid 20 E) or automatized reading (ATB 32 GN).
