1992年9月9日至2001年4月29日期间，在泰国的八个省份对小型哺乳动物进行了广泛的采样。共采集标本22种3,498份。88%（3，498只动物中的3，089只）是从清莱省的一个地区收集的，该地区通常被认为是人类恙虫病的地方病。检测每只动物的血液和组织样本是否存在恙虫病东方体（恙虫病的病原体）。优势鼠种为黄家鼠（53%，n = 1，863）、黄胸鼠（R. losea（18%，n = 638）、板齿鼠（16%，n = 564）和R. exulans（4%，n = 146）。22种哺乳动物中有10种检出恙虫病东方体，其中包括恙虫病东方体。bukit（25%感染，1/4）、R. rattus（23%，419/1，855），R. argentiventer（22%，5/23），R. berdmorei（22%，2/9），R. Losea（13%，82/638），B. indica（9%，52/564）、R. koratensis（8%，1/12），B. savilei（3%，1/30），R. exulans（1%，2/146）和树鼩（2%，1/49）。在清莱（18%感染，3,084只中有563只）、曼谷（11%，9只中有1只）、素可泰（3%，30只中有1只）和农塔武里（1%，69只中有1只）省发现了感染动物。对恙虫病维护和传播的影响进行了讨论。
Extensive sampling of small mammals was conducted in eight provinces of Thailand between September 9, 1992 and April 29, 2001. A total of 3,498 specimens representing 22 species were collected. Eighty-eight percent (3,089 of 3,498) of the animals were collected from a region in Chiangrai Province, which is commonly recognized as endemic for human scrub typhus. Blood and tissue samples from each animal were tested for the presence of Orientia tsutsugamushi, the etiologic agent of scrub typhus. The predominant species collected were Rattus rattus (53%, n = 1,863), R. losea (18%, n = 638), Bandicota indica (16%, n = 564), and R. exulans (4%, n = 146). Orientia tsutsugamushi was detected in 10 of the 22 species of mammals that included R. bukit (25% infected, 1 of 4), R. rattus (23%, 419 of 1,855), R. argentiventer (22%, 5 of 23), R. berdmorei (22%, 2 of 9), R. losea (13%, 82 of 638), B. indica (9%, 52 of 564), R. koratensis (8%, 1 of 12), B. savilei (3%,1 of 30), R. exulans (1%, 2 of 146), and Tupaia glis (2%, 1 of 49). Infected animals were found in Chiangrai (18% infected, 563 of 3,084), Bangkok (11%, 1 of 9), Sukothai (3%, 1 of 30), and Nonthaburi (1%, 1 of 69) Provinces. The implications towards scrub typhus maintenance and transmission are discussed.
