Biochemical characteristics and fatty acid composition of Gilardi rod group 1 bacteria.
Fifteen strains of eugonic, nonoxidative, gram-negative rods isolated primarily from human wounds of the extremities and blood formed a distinct group which was designated Gilardi rod group 1. The phenotypic characteristics of Gilardi rod group 1 were most similar to those of CDC group M-5, with the major difference that nitrite reduction was observed with CDC group M-5. All 15 strains of Gilardi rod group 1 possessed a distinct fatty acid profile which was characterized by large amounts (> 15%) of cis-vaccenic (18:1 omega 7c), palmitic (16:0), myristic (14:0), and lactobacillic (19:0 cyc11,12) acids and moderate amounts (3 to 5%) of lauric (12:0), 3-hydroxylauric (3-OH-12:0), and palmitoleic (16:1 omega 7c) acids. This fatty acid profile is unique compared with the profiles of CDC group M-5 and other bacteria we have tested and is useful for the rapid identification of Gilardi rod group 1 isolates.
