Abstract
The cellular fatty acid compositions of the lectotype strain and four clinical isolates of Pseudomonas marginata were determined by gas-liquid chromatography and compared with 11 strains of the Centers for Disease Control Pseudomonas-like group 2, which are similar to P. marginata in a number of conventional biochemical tests. Isolates of P. marginata were readily distinguished from Pseudomonas-like group 2 by the presence of a C17:0 cyclopropane acid and hydroxy acids 3-OH-C14:0, 2-OH-C16:0, 3-OH-C16:0, and 2-OH-C18:1, whereas strains of Pseudomonas-like group 2 contained C16:1 delta 9 as a major acid with small amounts of 3-OH-C12:0 and 2-OH-C14:0 acids. Our data show that cellular fatty acid composition provides useful additional information that can be combined with selected conventional tests to provide a more reliable and rapid identification of P. marginata and related bacteria.Entities:
