“…Canine heartworm disease typically presents with clinical signs of cough, weight loss, heart murmur and pulmonary crackles due to the presence of adult worms in the pulmonary arterial tree and, in cases of severe worm burden, in the right atria and ventricle, and the caudal vena cava (Bowman and Atkins 2009). Several case reports have described aberrant migration of adult heartworm to other sites, including the epidural space of the spinal cord, stifle joint, peritoneal cavity, brain, subcutaneous tissue and eye (Schnelle and Jones 1945, Segedy and Hayden 1978, Swist 1980, Hamir 1987, Blass and others 1989, Carastro and others 1992, Hodges and Rishniw 2008, Oh and others 2008, Favole and others 2013). According to published reports, adult heartworms have been identified in the femoral arteries (systemic arterial dirofilariasis) from at least 10 dogs (Burt and others 1977, Stuart and others 1978, Cooley and others 1987, Frank and others 1997, Goggin and others 1997, Slonka and others 1997).…”

A two‐year‐old intact male Anatolian shepherd dog presented with a one‐month history of bilateral hindlimb lameness and digital necrosis. Supportive evidence of systemic arterial parasitism included ultrasonographic findings of parallel hyperechoic thrombi in the femoral arteries consistent with the presence of nematodes. Worms retrieved during arteriotomy were identified as adult Dirofilaria immitis using light and scanning electron microscopy. Treatment included adulticidal therapy, bilateral femoral arteriotomies and finally, bilateral amputation at the level of the tarsocrural joints followed by external coaptation with walking bars. This is the 10th reported case of femoral arterial dirofilariasis causing clinical disease in a dog, and the first in which bilateral amputation was performed. Systemic arterial dirofilariasis should be on the list of differential diagnoses for any animal in a heartworm endemic area that presents with hindlimb lameness or necrosis, especially if the animal has weak femoral pulses.

“…Moreover, only a few studies have described aberrant migration of parasites into unique anatomical sites in dogs including the eye (Dantas-Torres et al 2009), articular joint (Hodges and Rishniw 2008), and kidney (Aresu et al 2007). Herein we report the first case of aberrant dirofilariasis in the uterus of a dog that resulted in granulomatous metritis.…”

“…However, aberrant parasite migration into atypical sites such as the nervous, reproductive, urinary, or skeletal systems can also occur and can induce inappropriate tissue injury. Several previous publications in the veterinary medical literature have reported such aberrant parasite distribution affecting the spinal cord (Gomez et al 2010;Johnson et al 2010), brain (Tanabe et al 2007), kidney (Aresu et al 2007), eye (Dantas-Torres et al 2009) and joint spaces (Hodges and Rishniw 2008). From these reports, a variety of important differential diagnoses have evolved concerning the clinical signs and pathologic lesions that can develop due to aberrant parasitic life cycles.…”

ABSTRACT:Here we describe a unique uterine mass in a dog with granulomatous lesions caused by filarial larvae from the family Onchocercidae. An 8-year-old female Maltese was presented to a local animal hospital with anorexia, depression, and vaginal discharge. A markedly distended uterus was observed on lateral abdominal radiographs, leading to a clinical diagnosis of pyometra or uterine mass of an unknown origin. During surgery, the left uterine horn contained a 5 cm diameter mass adhered to adjacent soft tissue. On gross inspection, the mass contained numerous white nematodes. Microscopically, this mass was characterised by a granulomatous inflammation of the myometrium and endometrium. Because all of the nematodes were dead, definitive species identification was not possible. However, based on the histologic appearance, these nematodes were tentatively identified as Dirofilaria immitis larvae.

“…A doença pode afetar diversos órgãos, incluindo o coração, os pulmões, fígado e rins (Hodges & Rishniw, 2008), no qual o estado clínico está relacionado ao número de parasitos adultos presentes e a resposta de cada animal à infecção (Dantas-Torres & Otranto, 2020). Em animais sintomáticos, destaca-se a insuficiência cardiorrespiratória (Smith Jr. et al, 2015).…”

A dirofilariose é uma importante zoonose considerada endêmica no Brasil, cuja transmissão acontece principalmente por meio de mosquitos vetores dos gêneros Culex, Aedes e Anopheles e que tem o cão doméstico como hospedeiro. Apesar da maioria dos animais serem assintomáticos, a doença pode afetar diversos órgãos, culminando em possíveis alterações em diagnósticos laboratoriais. Pode ser empregado diversos diagnósticos , sendo a visualização de microfilárias de Dirofilaria spp. em esfregaço sanguíneo o mais utilizado. O objetivo do trabalho foi verificar o perfil hematológico e bioquímico de cães diagnosticados com microfilárias de Dirofilaria immitis na cidade de Fortaleza, Ceará. Foram selecionadas amostras sanguíneas no período de agosto de 2014 a junho de 2018. Nas amostras em que houve positividade para a presença de microfilárias no esfregaço sanguíneo foi realizado um levantamento das alterações encontradas nos exames hematológicos e bioquímicos. Em 2.400 amostras de sangue analisadas, 26 apresentaram microfilárias (1,1%), com 46% de anemia e 46% com sinais de regeneração eritrocitária, 42% apresentaram trombocitopenia e 46% hiperproteinemia, com linfopenia em 61% dos casos. No perfil bioquímico, foram observadas discretas alterações abaixo do normal, exceto para albumina, que foi reduzida em 62% dos casos. A maioria dos analitos apresentaram valores normais, indicando que não havia uma hiperfunção ou hiperatividade dos órgãos. Logo, a dirofilariose influenciou na imunologia canina e, provavelmente, induziu a uma redução no número de plaquetas e aumento nas proteínas totais pelo estímulo inflamatório gerado.
