AN IDENTIFICATION SCHEME FOR RAPIDLY AND AEROBICALLY GROWING GRAM-POSITIVE RODS

An identification scheme for aerobically growing Gram-positive rods (g enera Actinomyces, Arcanobacterium, Aureobacterium, Bacillus, Brevibac terium, Cellulomonas, Corynebacterium, Dermabacter, Erysipelothrix, Ga rdnerella, Lactobacillus, Listeria, Microbacterium, Oerskovia, Propion ibacterium, Rhodococcus, Rothia, Turicella, as well as unnamed CDC gro ups, Clostridium tertium, and Mycobacterium fortuitum/chelonae) is pre sented. It is derived from the Hollis-Weaver scheme and uses catalase, oxidative/fermentative carbohydrate metabolism and motility as primar y reactions. Tests for lipophilism, nitrate reduction, urease, esculin hydrolysis, the CAMP reaction, acid formation from five carbohydrates , as well as for some facultative reactions should lead to a correct d iagnosis based on information available at the end of 1995.
