Parasitic myelopathy by Gurltia Paralysans
Parasitic myelopathy by Gurltia paralysans is, apparently,a South American disease, but little is known about it. It isa medullary disorder caused by a parasite that in its adultform, it is lodged in the spinal veins of cats causing a hemorrhageby suffusion that compromises the spinal cord in avariable way.It has been proposed that domestic cats are accidentalguests, and that small wild cats such as the huiña cat (Felisguigna) in Chile, or the cat of the pampas (Felis geoffroyi)in Brazil and Argentina, are the definitive hosts, housingthe parasite in the lung. Cats are likely infected by ingestingsmall lizards. The affected animals present typical signsof chronic myelopathy, with varying degrees of affection,from ataxia to severe paraparesis, depending on the timeof evolution. The main lesions are between T10 and L2,with projection up to L5-L6. The affected cats always livein rural areas, and this parasitosis has not been diagnosedin any urban area. The diagnosis is based on the clinicalhistory of slowly progressive chronic myelopathy and thehabitat of sick cats. Recently a PCR technique has been developedthat allows the identification of parasitic DNA inthe CSF of the affected cats. The treatment is based on theapplication of ivermectin, and it is most effective if it is implementedearly.

La mielopatía parasitaria por Gurltia paralysans es una enfermedad aparentemente sudamericana, y poco conocida. Se trata de un trastorno medular provocado por un parásito que, en su forma adulta, se aloja en las venas espinales de los gatos provocando una hemorragia por sufusión que compromete a la médula de manera variable. Se ha propuesto que los gatos domésticos son huéspedes accidentales, y que pequeños felinos salvajes como el gato huiña (Felis guigna) en Chile, o el gato de las pampas (Felis geoffroyi) en Brasil y Argentina, son los verdaderos huéspedes definitivos, alojando al parásito en el pulmón. Es probable que los gatos se infecten ingiriendo pequeños lagartos. Los animales afectados presentan signos típicos de una mielopatía crónica, con grados de afección variables, desde ataxia a paraparesia grave, dependiendo del tiempo de evolución. Las lesiones principales se encuentran entre T10 y L2, con proyección hasta L5-L6. Los gatos afectados residen siempre en áreas rurales, no habiéndose diagnosticado esta parasitosis en ningún sitio urbano. El diagnóstico se establece en base a la historia clínica de mielopatía crónica lentamente progresiva y el hábitat de los gatos enfermos. Recientemente se ha desarrollado una técnica de PCR que permite identificar ADN parasitario en el suero y en el LCR de los gatos afectados. El tratamiento se base en la aplicación de ivermectina, y es tanto más eficaz cuanto más precozmente se comience la terapia.
