From June 2005 to November 2010, 43 small mammals encompassing 6 species of Didelphimorphia, 8 species of Rodentia, and 1 species of Lagomorpha were found parasitized by ticks in the state of Minas Gerais, southeastern Brazil. Nine tick species, in total 186 specimens, were identified as follows: Amblyomma cajennense (larvae and nymphs) on opossums and rodents; Amblyomma ovale (nymphs) on rodents; Amblyomma parvum (nymphs) on rodents; Amblyomma coelebs (nymphs) on opossums; Amblyomma dubitatum (nymph) on opossums; Ixodes amarali (females, nymphs, and larvae) on opossums and rodents; Ixodes loricatus (male, females, nymph) on opossums; Ixodes schulzei (female) on rodents; and Haemaphysalis leporispalustris (female) on rabbits. Most of the tick-host associations found in the present study have never been recorded in the literature; those include three new host records for I. amarali, four for A. cajennense, one for A. dubitatum, two for A. ovale, and one for A. coelebs. In addition, we provide the first record of A. coelebs in the state of Minas Gerais.
从 2005 年 6 月至 2010 年 11 月，在巴西东南部的米纳斯吉拉斯州发现了 43 只小型哺乳动物，包括 6 种袋目动物、8 种啮齿目动物和 1 种兔形目动物，它们都被蜱虫寄生。共鉴定出 9 种蜱虫，总计 186 只标本，如下：在负鼠和啮齿动物上发现了肩突钝缘蜱（幼虫和若虫）；在啮齿动物上发现了卵形钝缘蜱（若虫）；在啮齿动物上发现了小钝缘蜱（若虫）；在负鼠上发现了臀点钝缘蜱（若虫）；在负鼠上发现了怀疑钝缘蜱（若虫）；在负鼠和啮齿动物上发现了美洲钝缘蜱（雌蜱、若虫和幼虫）；在负鼠上发现了林地革蜱（雄蜱、雌蜱、若虫）；在啮齿动物上发现了舒氏革蜱（雌蜱）；在兔子上发现了野兔革蜱（雌蜱）。本研究中发现的大多数蜱-宿主关系以前从未在文献中记录过；其中包括三种美洲钝缘蜱的新宿主记录、三种肩突钝缘蜱、一种卵形钝缘蜱、一种怀疑钝缘蜱、两种卵形钝缘蜱和一种臀点钝缘蜱。此外，我们还提供了该州首次记录的臀点钝缘蜱。
