Abstract
The cellular fatty acid composition of a group of gram-negative nonfermentative organisms designated group IVe was studied by GLC. Strains of this group are isolated most frequently from urine and most closely resemble the Alcaligenes in conventional biochemical tests. On the basis of cellular fatty acids, these organisms were strikingly different from Alcaligenes and other gram-negative species with similar phenotypic characteristics. The GLC procedure offers an additional diagnostic test for rapid identification of unclassified bacteria like group IVe.
