Abstract：
Calodium hepaticum (syn. Capillaria hepatica) is a nematode responsible for parasitic zoonosis that can cause granulomatous lesions in the liver. Although murids are the main hosts, C. hepaticum has been documented in a wide range of mammals. Here, we report a case of hepatic calodiosis in a 6-month-old dog that was rescued in the municipality of Cuiabá, Mato Grosso state, midwestern Brazil. Even after being attended at a Veterinary Hospital, the case resulted in animal death. Necroscopic examination revealed significant macroscopic changes in the spleen, liver, and encephalus. Microscopic examination revealed parasitic eggs, identified as Calodium cf. hepaticum, that were rounded to oval with a bilamellar cuticle, radially striated, and with bipolar plugs. Considering the difficulty to diagnose this parasite, and the existence of diverse possible hosts in Mato Grosso due to the biodiversity of the state, further investigation is required to understand the true prevalence of C. hepaticum and the importance of this nematode in public health.
摘要：
肝肠（同理。肝毛细血管）是一种线虫，可引起寄生虫人畜共患病，可引起肝脏肉芽肿性病变。尽管鼠类是主要宿主，已经在广泛的哺乳动物中记录了肝梭菌。这里,我们报告了一例在Cuiabá市获救的6个月大的狗的肝钙化病，马托格罗索州,巴西中西部。即使在兽医医院就诊后，此案导致动物死亡。尸检显示脾脏有明显的宏观变化，肝脏,还有脑.显微镜检查发现有寄生虫卵,鉴定为Calodiumcf。肝部,圆形到椭圆形，有双层角质层，径向条纹，和双极插头。考虑到诊断这种寄生虫的难度，由于该州的生物多样性，马托格罗索州存在多种可能的寄主，需要进一步调查以了解肝菌的真实患病率以及这种线虫在公共卫生中的重要性。
