Two outbreaks of progressive hind limb paresis in cats (Felis catus) caused by parasitic meningomyelitis in Uruguay are reported. The case studies occurred in 2008 and 2009 respectively, in the rural areas of Fray Bentos (33° 07' 40.39'' S) and were characterized by hindquarter paralysis. This paralysis was progressive and had a chronic progression of approximately 12 months until the death or euthanasia of the animals. Clinical symptoms started with ataxia of the hindquarters with lateral side-to-side swaying and culminated in total paralysis. Two animals were sent for necropsy in 2009. The main histopathological findings were severe myelitis in the lumbar spinal cord with perivascular cuffing and white matter necrosis, severe nonsuppurative meningitis with thrombi in subarachnoid blood vessels, and intravascular presence of multiple adult parasites. From the morphological characteristics of the parasites and location in the leptomeninges, the parasite was identified as the nematode Gurltia paralysans.
据报道，乌拉圭发生了两起因寄生虫性脑脊膜炎导致猫（家猫）出现进行性后肢轻瘫的疫情。病例研究分别于2008年和2009年在弗赖本托斯（南纬33°07′40.39″）的农村地区出现，其特征为后躯麻痹。这种麻痹呈进行性，慢性发展约12个月，直至动物死亡或实施安乐死。临床症状始于后躯共济失调，伴有左右摇摆，最终发展为完全麻痹。2009年将两只动物送去进行尸检。主要组织病理学发现为腰段脊髓严重脊髓炎，伴有血管周围套袖状浸润和白质坏死，严重非化脓性脑膜炎，蛛网膜下血管有血栓形成，血管内有多个成虫寄生虫。根据寄生虫的形态特征和在软脑膜中的位置，该寄生虫被鉴定为线虫类的麻痹古氏线虫。
