[Comparative evaluation of 3 miniaturized systems (API 20E, Enterotube II, Sensititre AP60) commonly used in clinical microbiology laboratories].

API 20E, Enterotube II, Sensititre AP60 have been evaluated. Some biochemical tests (lysine, ornithine, VP, H2S, adonitol , arabinose, citrate) have revealed significative differences among three systems. The total correlations about bacterial identifications have been very similar. The repetibility of identifications of strains isolated from clinical specimens has been 98.7% for Enterotube and API 20E, 95.5% for Sensititre . The biochemical tests have revealed repetibility greater than or equal to 94%, citrate repetibility instead has been 91%.
