根据56 kDa型特异性抗原基因的同源性，对31株恙虫病东方体分离株（日本20株，韩国2株，中国1株，东南亚8株）进行系统发育分析。日本、韩国和中国的分离株在系统发育树中分别被划分为8个不同的类群，分别命名为JG（日本Gilliam型）、JP-1和JP-2（日本Karp 1和2型）、Kato、川崎、Kuroki、Shimokoshi和LX-1型。所有来自东南亚的O.分布在亚洲东北部和东南亚的恙虫病是不同类型的。(C)1999年，欧洲微生物学会联合会。由Elsevier Science B. V.出版，版权所有。
Close and distant relationship among 31 strains of Orientia tsutsugamushi (20, two, one and eight strains were isolated in Japan, Korea, China and southeast Asia, respectively) were clarified using phylogenetic analyses based on homologies of 56-kDa type specific antigen genes. Isolates in Japan, Korea and China were located in eight separate clusters in the phylogenetic tree, and each was designated as JG (Japanese Gilliam type), JP-1 and JP-2 (Japanese Karp 1 and 2 types), Kato, Kawasaki, Kuroki, Shimokoshi and LX-1 types. All isolates originated in southeast Asia, including the prototype Gilliam and Karp strains isolated in Burma and New Guinea, respectively, were distantly located in the phylogenetic tree from those isolates in Japan, Korea and China, indicating that strains of O. tsutsugamushi distributed in northeastern and southeastern Asia are different types.
