Current taxonomy and identification of nonfermentative gram negative bacilli.

In recent years significant advances have been made in the characterization and taxonomy of nonfermentative bacilli as well as in the recognition of their pathogenic potential for man. In addition, certain other infrequently isolated bacteria that may be fermentative have been recognized, and improved methods for their identification have been developed. This discussion attempts to present a practical approach to the identification of these micro-organisms in the clinical microbiology laboratory.
