Biochemical characterization of Haemophilus species with the minitek differentiation system

Characterization of 102 Haemophilus strains by the Minitek differentiation system (BBL Microbiology Systems, Cockeysville, Md.) was compared with that by the conventional method. The results obtained by the two methods were in good agreement (P less than 0.001; test of independence). Therefore, this system was found to be applicable for the identification of Haemophilus species in routine clinical bacteriology.
