A Probability Matrix for the Identification of Gram-negative, Aerobic, Non-fermentative Bacteria that Grow on Nutrient Agar

Results of the identification of 621 strains of Gram-negative, aerobic, non-fermentative bacteria by a computer-based probabilistic method are given. Although many of the strains were atypical and have caused difficulty in identification in the medical diagnostic laboratory, the identification rate on this matrix was 91.5%.
