The modes of stylostome formation by larvae (chiggers) of Leptotrombidium intermedium, L. fletcheri, L. arenicola, and L. deliense in parasitized mouse skin were studied histologically in relation to their capacity to transmit Rickettsia tsutsugamushi. Three types of stylostome formation were recognized among the different species: the epidermal stylostome formed by the larva of L. intermedium; the mesenchymal stylostome formed by the larva of L. fletcheri; and, the mixed stylostome formed by the larva of both L. arenicola and L. deliense. Dermal inflammations related to the three types of stylostomes were histologically defined. The possible importance of stylostome characteristics to the transmission of rickettsial organisms is discussed.
对居中纤恙螨、弗氏纤恙螨、沙栖纤恙螨和地里纤恙螨幼虫（恙螨）在寄生小鼠皮肤中形成吸管状口器的方式进行了组织学研究，并探讨了其与传播恙虫病立克次体能力的关系。在不同物种中识别出三种类型的吸管状口器形成方式：居中纤恙螨幼虫形成的表皮吸管状口器；弗氏纤恙螨幼虫形成的间充质吸管状口器；以及沙栖纤恙螨和地里纤恙螨幼虫均能形成的混合吸管状口器。从组织学角度明确了与这三种类型吸管状口器相关的皮肤炎症。讨论了吸管状口器特征对立克次体生物传播的潜在重要性。
