From 2008 to 2010, southern plains woodrats (Neotoma micropus) from southern Texas, were examined for parasites and selected pathogens. Eight helminth species were recovered from 97 woodrats including, Trichuris neotomae from 78 (prevalence = 80%), Ascarops sp. from 42 (43%), Nematodirus neotoma from 31 (32%), Raillietina sp. from nine (9%), Taenia taeniaeformis larvae from eight (8%), and an unidentified spiurid, a Scaphiostomum sp. and a Zonorchis sp. each from a single woodrat. Besnotia neotomofelis was detected in three (3%) woodrats and microfilaria were detected in seven (7%). Polymerase chain reaction (PCR) testing of blood samples from 104 woodrats detected a novel Babesia sp. in one (1%) and Hepatozoon sp. in 17 (16%) woodrats. Partial 18S rRNA gene sequence of the Babesia was 94% similar to B. conradae. Histologic examination of tissues detected intestinal coccidia in seven of 104 (7%), Sarcocystis neotomafelis in 26 (25%), Hepatozoon sp. in 21 (20%), and Dunnifilaria meningica in four (4%) woodrats. Three woodrats (5%) were seropositive for Toxoplasma gondii. Ectoparasites recovered included fleas (Orchopeas sexdentatus and O. neotomae), ticks (Ixodes woodi and Ornithodoros turicata), mites (Trombicula sp. and Ornithonyssus (Bdellonyssus) bacoti) and bot flies (Cuterebra sp.). The only difference in prevalence related to gender was for N. neotoma (males > females, p = 0.029). Prevalence of T. neotomae and all intestinal parasites combined was significantly higher in adults compared with juveniles (p = 0.0068 and p =0.0004), respectively. Lesions or clinical signs were associated with Cuterebra and B. neotomofelis. Collectively, these data indicate that woodrats from southern Texas harbor several parasites of veterinary and/or medical importance.
从 2008 年到 2010 年，对来自德克萨斯州南部的南方平原林鼠（Neotoma micropus）进行了寄生虫和选定病原体检查。从 97 只林鼠中分离出 8 种寄生虫，包括 78 只（流行率=80%）的 Trichuris neotomae、42 只（43%）的 Ascarops sp.、31 只（32%）的 Nematodirus neotoma、9 只（9%）的 Raillietina sp.、8 只（8%）的 Taenia taeniaeformis 幼虫和一种未鉴定的 spiroid、一种 Scaphiostomum sp.和一种 Zonorchis sp.。在 3 只（3%）林鼠中检测到 Besnotia neotomofelis，在 7 只（7%）林鼠中检测到微丝蚴。对 104 只林鼠的血液样本进行聚合酶链反应（PCR）检测，在 1 只（1%）林鼠中检测到一种新的 Babesia sp.，在 17 只（16%）林鼠中检测到 Hepatozoon sp.。Babesia 的部分 18S rRNA 基因序列与 B. conradae 相似 94%。对 104 只林鼠的组织进行组织学检查，在 7 只（7%）林鼠中检测到肠道球虫、26 只（25%）林鼠中检测到 Sarcocystis neotomafelis、21 只（20%）林鼠中检测到 Hepatozoon sp.和 4 只（4%）林鼠中检测到 Dunnifilaria meningica。3 只（5%）林鼠的血清对刚地弓形虫呈阳性。回收的外寄生虫包括跳蚤（Orchopeas sexdentatus 和 O. neotomae）、蜱（Ixodes woodi 和 Ornithodoros turicata）、螨（Trombicula sp.和 Ornithonyssus（Bdellonyssus）bacoti）和蝇蛆（Cuterebra sp.）。与性别相关的唯一流行率差异是 N. neotoma（雄性>雌性，p = 0.029）。与幼鼠相比，成年鼠的 T. neotomae 和所有肠道寄生虫的总流行率显著更高（p = 0.0068 和 p = 0.0004）。与 Cuterebra 和 B. neotomofelis 相关的病变或临床症状。总的来说，这些数据表明，来自德克萨斯州南部的林鼠携带几种具有兽医和/或医学重要性的寄生虫。
