“…The most common clinical manifestation of feline gurltiosis is chronic and progressive ambulatory paraparesis or paraplegia (Gómez and others 2010, Mieres and others 2013, Togni and others 2013). Other clinical signs associated with this parasitism include pelvic limb ataxia, pelvic limb proprioceptive deficits, pelvic limb tremors, pelvic limb muscle atrophy, tail trembling, tail atony, and faecal and urinary incontinence (Gómez and others 2010, 2011, Alzate and others 2011, Guerrero and others 2011, Moroni and others 2012, Mieres and others 2013, Togni and others 2013). The duration of clinical signs usually ranges from 2 weeks to 48 months (Gómez and others 2010, Mieres and others 2013, Togni and others 2013).…”

“…The geographical distribution of G paralysans includes areas of Argentina, Colombia, Uruguay, Chile and Brazil (Alzate and others 2011, Guerrero and others 2011, Rivero and others 2011, Moroni and others 2012, Togni and others 2013). The nematode exhibits neurovascular tropism and is found primarily in the leptomeningeal and parenchymal veins of the spinal cord, mainly in the lumbosacral area.…”

Gurltia paralysans is an uncommon neuroparasite that affects domestic cats in South America. The authors herein report a case of an adult male domestic cat with a three-month history of progressive hindlimb paralysis. Neuroanatomical evaluation indicated compromise of the thoracolumbar and lumbosacral spinal cord segments. An authorised euthanasia was performed because of the guarded prognosis. Postmortem examination findings included leptomeningeal vein congestion and varicose veins, especially in the T9–T13 spinal cord segments. One male and 11 female adult G paralysans nematodes were recovered from the spinal subarachnoid veins of the affected areas. Histopathological examination revealed dilatation and congestion of several leptomeningeal vessels and parasitic eggs within both nematodes and intravenous thrombi. Several mononuclear inflammatory cells surrounded a mineralised section of nematodes in the meningeal space. Feline gurltiosis should be considered as an important differential diagnosis in cats with neurological signs secondary to thoracolumbar and/or lumbosacral spinal cord lesions.

“…Para os habitantes locais da selva valdiviana, tanto o huiña como o gato doméstico infectam-se ingerindo pequenos lagartos (Levine 1968). No entanto, na descrição original desse parasitismo (Wolffhügel 1934), insetos (moscas e besouros), moluscos (caramujos ou lesmas), sapos e roedores também foram considerados como possíveis hospedeiros intermediários ou paratênicos (Moroni et al 2012).…”

ABSTRACT.-Togni M., Panziera W., Souza T.M., Oliveira Filho J.C., Mazzanti A., Barros C.S. In the last 20 years, an unknown neurological disease affected cat populations in the Western Border Region of the State of Rio Grande do Sul, Brazil. The onset of the disease was characterized by tail paralysis, followed by progressive paraparesis in the pelvic limbs, difficulty in ambulation and proprioceptive ataxia. After long prolonged clinical courses (12-24 months), when then affected cats became severely paraparetic and start to develop pressure sores do to decubitus, they were destroyed by the owners. At necropsy there were variable degrees of skeletal muscle atrophy of the pelvic muscles and some degree of reddening of the meninges at the level of T10-L7, due to the presence of a myriad of small blood vessels, as a typical varicose lesion that resembled a vascular hamartoma. Histologically, such lesions consisted of distension of the subarachnoid space due to a collection of dilated, blood-filled, tortuous blood vessels the lumina of which were occasionally partially or completely occluded by thrombi. Those varices were randomly surrounded by a lymphocytic or granulomatous inflammatory infiltrate with small foci of mature eosinophils. In the lumina of these varicose venules cross and longitudinal sections of nematode parasites could be observed. Based on the morphology of these parasites, in their anatomical localization (meningeal blood vessels) and in the species (cat) affected the nematode was identified as Gurltia paralysans. This paper describes detailed aspects of the epidemiology, clinical disease and pathology of this intriguing feline myelopathy and the definitive diagnosis of the condition: Feline crural parasitic paraplegia, a disease first described in Chile in the 1930's and now, for the first time, in Brazil. RESUMO.-Nos últimos 20 anos, uma doença neurológica desconhecida acometeu populações de gatos da Região da Campanha do RS e tornou-se um desafio diagnóstico para os veterinários locais. Os gatos afetados desenvolviam inicialmente paralisia da cauda, seguida de paraparesia progressiva nos membros pélvicos, alteração da marcha, posição plantígrada e ataxia proprioceptiva. Após longos períodos de evolução clínica (12-24 meses), quando se tornavam marcadamente paraparéticos e começavam a apresentar escaras de decúbito, eram sacrificados pelos proprietários. Na necropsia, demonstravam graus variados de atrofia dos músculos pélvicos e algum grau de avermelhamento das meninges entre T10 e L7, devido à presença de miríades
