Rodents are small mammals that can be parasitized by various helminths. This study aimed to identify and describe the ecological indicators of infection in rodents captured in fragments of the Atlantic Forest in the western region of Paraná State, Brazil. Sixty-eight specimens of five rodent species were collected, necropsied, and inspected in search of helminths. The parasites were stored in 70% ethanol, morphologically identified, and counted for calculation of infection indicators. Fourteen species of helminths and one species of Crustacea were recorded: ten in Akodon montensis, four in Mus musculus, two in Thaptomys nigrita, two in Oligoryzomys nigripes, and one in Euryoryzomys russatus. The registered species of parasites were: Rodentolepis akodontis, Angiostrongylus sp., Protospirura numidica criceticola, Trichuris navonae, Syphacia alata, Syphacia criceti, Syphacia evaginata, Trichofreitasia lenti, Stilestrongylus aculeata, Stilestrongylus eta, Stilestrongylus gracielae, Stilestrongylus franciscanus, Stilestrongylus moreli, Stilestrongylus sp., and Pentastomida gen. sp. A positive correlation between the intensity of infection of T. navonae and T. lenti was observed with the body condition index of the host A. montensis. For all species, this study represents a new register of locality, and for eight of them a new host.
啮齿动物是可以被各种寄生虫寄生的小型哺乳动物。本研究旨在鉴定和描述在巴西巴拉那州西部地区大西洋森林片段中捕获的啮齿动物的感染生态指标。共收集了 5 种啮齿动物的 68 个标本，进行解剖并检查以寻找寄生虫。寄生虫保存在 70%乙醇中，进行形态学鉴定并计数，以计算感染指标。记录到 14 种寄生虫和 1 种甲壳类动物：10 种在 Akodon montensis 中，4 种在 Mus musculus 中，2 种在 Thaptomys nigrita 中，2 种在 Oligoryzomys nigripes 中，1 种在 Euryoryzomys russatus 中。登记的寄生虫种类有：Rodentolepis akodontis、Angiostrongylus sp.、Protospirura numidica criceticola、Trichuris navonae、Syphacia alata、Syphacia criceti、Syphacia evaginata、Trichofreitasia lenti、Stilestrongylus aculeata、Stilestrongylus eta、Stilestrongylus gracielae、Stilestrongylus franciscanus、Stilestrongylus moreli、Stilestrongylus sp. 和 Pentastomida gen. sp. 观察到 T. navonae 和 T. lenti 的感染强度与宿主 A. montensis 的身体状况指数呈正相关。对于所有物种，本研究代表了一个新的地点记录，对于其中 8 个物种来说是一个新的宿主记录。
