Thirteen species of ectoparasitic (12) or phoretic (1) arthropods were collected from 26 adult Virginia opossums, Didelphis virginiana, live-trapped from April through September 1987 in Davidson County, Tennessee. The cat flea Ctenocephalides felis and the American dog tick Dermacentor variabilis were the predominant species with respect to mean intensity and prevalence. The macronyssid mite Ornithonyssus wernecki and the atopomelid mite Didelphilichus serrifer, both specific parasites of this host, showed high intensities but low prevalences. Other fleas collected were Cediopsylla simplex, Ctenophthalmus pseudagyrtes, and Orchopeas howardi. The tick Amblyomma americanum, the myobiid mite Archemyobia inexpectatus, and the trombiculid (chigger) mites Eutrombicula splendens, Leptotrombidium peromysci (first record from this host) and Neotrombicula cavicola (first record from this host), were also recorded. One phoretic species, the glycyphagid mite Marsupialichus brasiliensis, was noted.
1987年4月至9月间，在田纳西州戴维森县通过活捉捕获了26只成年弗吉尼亚负鼠（Didelphis virginiana），从这些负鼠身上采集到了13种体表寄生（12种）或携带（1种）节肢动物。就平均感染强度和感染率而言，猫蚤（Ctenocephalides felis）和美洲犬蜱（Dermacentor variabilis）是主要种类。长须螨（Ornithonyssus wernecki）和锯缘负鼠螨（Didelphilichus serrifer）这两种该宿主的特异性寄生虫，感染强度高但感染率低。采集到的其他跳蚤有简单角叶蚤（Cediopsylla simplex）、拟奇刺蚤（Ctenophthalmus pseudagyrtes）和霍氏角叶蚤（Orchopeas howardi）。还记录到了美洲钝缘蜱（Amblyomma americanum）、意外肌螨（Archemyobia inexpectatus）以及恙螨（Eutrombicula splendens、白足鼠纤恙螨Leptotrombidium peromysci，首次记录于该宿主）和洞穴新恙螨（Neotrombicula cavicola，首次记录于该宿主）。发现了一种携带性种类，即巴西袋形螨（Marsupialichus brasiliensis）。
