In the present study, we first report the seroprevalence of Dirofilaria immitis in dogs in Shenyang, northeastern China. Sera from 528 randomly selected dogs were examined for D. immitis antigen using SNAP®4Dx test kit; 12.7% tested showed seropositive. No significant difference of infection was observed in different genders and breeds (P>0.05), but the difference was significant in different a...

background: heartworm ( dirofilaria immitis ) is mosquito-borne filarial nematode capable of causing serious cardiopulmonary disease in canines and felines, and pulmonary dirofilariasis in man. this research was conducted with the objectives of determining the incidence and assessing possible risk factors of canine heartworm in the southeast of iran. methods: from october 2012 to september 2013...

objective: to report a case of periocular dirofilariasis. patient and findings: a 27-year-old female referred with history of edema and redness in left eye for two days. on slit-lamp examination, a moving threadlike worm was seen in subconjunctival area. two days later a live filaria worm measuring 12 cm in length was extracted from lower lid subcutaneous tissue. the worm was diagnosed dirofila...

BACKGROUND Dirofilaria immitis and Dirofilaria repens are the most common species of filarial nematodes described in the dogs. A single-step multiplex PCR was applied to detect and differentiate simultaneously and unequivocally D. immitis and D. repens on DNA extracted from canine peripheral blood and besides to detect the seroprevalance of D. immitis by ELISA in Elazig Province, Turkey. A PCR ...

An asymptomatic patient with a pulmonary coin lesion surgically diagnosed with pulmonary dirofilariasis caused by infection with Dirofilaria immitis (D. immitis) is presented. The preoperative stored serum of the patient was positive for D. immitis by enzyme-linked immunosorbent assay (ELISA). A family study showed that three of five family members were seropositive for D. immitis. These result...

A survey on 87 dogs necropsied in the Townsville region revealed 34 (39%) were infected with Dirofilaria immitis. Infected dogs had an average of 6.1 adult worms in the heart and associated blood vessels. The VetRED assay detected 23 of the 34 infected dogs (sensitivity 65%) and the Og4C3 ELISA detected 27 (sensitivity 80%). Sensitivity of the VetRED and Og4C3 ELISA increased to 88 and 94% resp...

Dogs are a reservoir for Chagas disease, caused by Trypanosoma cruzi (T. cruzi), and other companion vector-borne diseases, including ehrlichiosis (Ehrlichia canis Ehrlichia ewingii), anaplasmosis (Anaplasma phagocytophilum Anaplasma platys), dirofilariasis (Dirofilaria immitis) Lyme disease (Borrelia burgdorferi). This study has two key objectives: 1) to determine seroreactivity against T. in ...

Iran is one of the endemic areas of Dirofilariasis, and also one of the most important zoonotic infections. Dirofilaria immitis causes a severe and fatal disease called heartworm disease in dog. It also produces pulmonary nodules in humans. The worm is to be investigated as a potential infection of humans and animals in various provinces in Iran. In this research, the samples were ...

of morphologic and molecular diagnostics is an absence of information on poorly described and characterized pathogens or new pathogens that have yet to be identified. No good algorithm exists to resolve these conflicts other than to explore all possibilities. The diagnosis in the described case is probably best left as a Dirofilaria species of the Dirofilaria (Nochtiella) type, members of which...

The dog parasite Dirofilaria immitis can infect humans. Patients with pulmonary dirofilariasis were tested for immunoglobulin G (IgG) antibodies against the surface protein of Wolbachia, the bacterial endosymbiont of D. immitis. These patients showed significantly higher IgG titers than healthy individuals from areas in which D. immitis was endemic as well as areas in which it was not endemic. ...
