Six Orientia strains including 3 prototype strains such as Gilliam, Karp, and Kato, and 3 strains (Boryong, Pajoo, and Yongworl) isolated in Korea, were studied for the profiles of their cellular fatty acids. All tested strains contained octadecenoic acid C 18:1 ω3±3.5%), octadecanoic acid C 18:0 (15.3±1.5%), and hexadecanoic acid C 16:0 (12.7±1.7%) as major components; however, interestingly, eicosenoic acid C 20:1 ω9 c (2.6 ±0.6%) was found in all strains except the Yongworl strain. Furthermore none of the strains contained 3‐hydroxy fatty acids. The ratios of total saturated fatty acid (SFA) to total unsaturated fatty acid (UFA) were within the range of 0.34 to 0.54. These results showed that the cellular fatty acid profile should provide more reliable information for the identification of these bacteria.
