Lesões Anatomopatológicas Presentes Na Infecção Por Dioctophyma Renale (Goeze, 1782) Em Cães Domésticos (Canis Familiaris,) Linnaeus, 1758

Abstract

Os autores descrevem as lesões anatomopatológicas de onze casos de parasitismo por Dioctophyma renale (Goeze, 1782), na cidade de Curitiba - PR, Brasil, constatados em necrópsias e achados clínicos em 1960 cães, no período de 1979 a 2004. Anatomopathologic lesions found in Dioctophyma renale (Goeze, 1782) infections in domestic dogs (Canis familiaris, LINNAEUS, 1758 Abstract The authors describe the anatomopathologic lesions of eleven cases of parasitism by Dioctophyma renale (Goeze, 1782), in Curitiba (PR, Brazil), found among 1960 necropsies carried out between 1979 and 2004 in dogs.

Ocorrência de Dioctophyma renale em Galictis cuja

“…O parasito tende a se localizar principalmente nos rins, ou livre na cavidade abdominal dos hospedeiros causando destruição progressiva das camadas cortical e medular dos rins, reduzindo os órgãos a uma cápsula ϐibrosa (Barros et al 1990, Leite et al 2005. O macho apresenta bolsa copuladora (desprovida de raios) localizada na extremidade posterior, no centro da bolsa abre-se o oriϐício cloacal de onde emerge um único espículo.…”

“…O parasito já foi relatado em um grande número de animais silvestres incluindo martas (Mustela vison), doninhas (Mustela sibirica coreana), graxains (Cerdocyon thous), quatis (Nasua nasua), lontras (Lutra longicaudis), preguiças (Choloepus didactylus), lobos-guará (Chrysocyon brachyurus), coiotes (Canis latrans), lobos (Canis Lupus), raposas vermelhas (Canis vulpes), chacais (Canis mesomelas), rato-almiscarado (Ondatra zibethica), guaxinins (Procyon lotor), mão-pelada (Procyon cancrivorous), ursos (Ursus ursus) e recentemente foi detectado em um macaco-prego (Cebus apella) no estado do Pará, Brasil (Leite et al 2005, Pesenti et al 2007, Amaral et al 2008, Ishizaki et al 2010, Tokiwa et al 2011. Adicionalmente existem relatos esporádicos de sua ocorrência em bovinos, equinos, suínos, felinos, focas e humanos todos considerados hospedeiros atípicos (Tokiwa et al 2011).…”

Pre- and post-operative evaluations of eight dogs following right nephrectomy due toDioctophyma renale

“…After infection, acquisition by ingestion, the larvae penetrate the duodenal wall, and later enter the abdominal cavity and migrate to the kidney where they mature into adult worms (Liu 2012). However, free worms have also been reported in the canine abdominal cavity, and sporadically at other bodily sites (Leite et al 2005;Nakagawa et al 2007;Sousa et al 2011;Maia et al 2012;Veiga et al 2012). The location of the adult worms may be correlated with the site where the infecting larvae penetrate the digestive tract (Osborne et al 1969;Kommers et al 1999).…”

“…In many clinical cases the aetiology of the infestation could not be determined (Sousa et al 2011), although contamination had been hypothesized due to the presence of aquatic environments (Pereira et al 2006;Nakagawa et al 2007;Ferreira et al 2010), or to the occurrence of another paratenic host such as rats, especially in stray dogs (Kommers et al 1999). In general, the adult worms are found more frequently in the right kidney, probably due to its anatomic proximity to the duodenum (Leite et al 2005;Nakagawa et al 2007;Soler et al 2008;Secchi et al 2010;Cottar et al 2012). After infection, acquisition by ingestion, the larvae penetrate the duodenal wall, and later enter the abdominal cavity and migrate to the kidney where they mature into adult worms (Liu 2012).…”

“…Therefore, in most canine cases, the diagnosis is made when eggs are observed in the urine, or during necropsy, or occasionally during surgical interventions (Kommer et al 1999;Leite et al 2005;Pereira et al 2006;Nakagawa et al 2007;Soler et al 2008;Silveira et al 2009;Lemos et al 2010;Secchi et al 2010). Imaging studies including ultrasound and computed tomography (CT) have been used to confirm the presence of the worms in the kidney as well as to identify the occurrence of the parasite inside the abdominal cavity or other organs (Soler et al 2008;Silveira et al 2009;Secchi et al 2010;Cottar et al 2012;Rahal et al 2014).…”
