Species of filarial nematodes belonging to the genera Dirofilaria and Acanthocheilonema are recognised as common parasites of dogs throughout the world. Recently, other filarioids featured by the presence of dermal microfilariae (e.g., Onchocerca lupi and Cercopithifilaria spp.) have been recognised in Europe. In Brazil, reports of filarioids in dogs are limited to Dirofilaria immitis, Acanthoc...

CHRISTENSEN, B. M. 1978. Dirofilaria immitis: Effect on the longevity of Aedes trivittatus. Experimental Parasitology 44, 116-123. Laboratory studies on vector mortality as related to parasite burden revealed that the mosquito Aedes trivittutus showed considerable tolerance to infection with the filarial nematode Dirofilaria immitis. Although mosquitoes exposed to a dog with a high microfilarem...

Human dirofilariasis is a zoonotic infectious disease caused by the filarial nematodes of dogs Dirofilaria repens and Dirofilaria immitis. Depending on the species involved, human infections usually manifest as one cutaneous or visceral larva migrans that forms a painless nodule in the later course of disease. Dirofilariae are endemic in the Mediterranean, particularly in Italy. They are consid...

dirofilaria immitis is a filariid worm which typically lives as adult in the right ventricle of the heart and the pulmonary arteries of the dog, causing the canine heartworm disease.therapy of canine dirofilariosis due to dirofilaria immitis is indicated for dogs suffering from clinical signs of the disease (such as chronic cough). the present paper describes diagnostic and treatment features o...

Morphological descriptions of Dirofilaria immitis are scarce. For this reason, we carried out morphological studies using both light and scanning electron microscopy for this filaroid species. Morphometric and morphological data were compatible with previous descriptions of D. immitis , but several anatomical structures are described by scanning electron microscopy for the first time, such as d...

Dirofilaria immitis is the causative agent of heartworm disease. Reports of macrocyclic lactone inefficacy prompted an investigation of genetic polymorphism in D. immitis. Currently, there is a lack of genetic information for this parasite. Information on baseline levels of genetic heterogeneity in the dog heartworm would have important implications for the possible development of macrocyclic l...

The second described case of solitary transient lung nodule caused by Dirofilaria immitis is reported. Diagnostic thoracotomy can be avoided with the use of enzyme-linked immunosorbent assay (ELISA), and hence a conservative serological follow-up is warranted in endemic areas.

Dirofilariasis of animals and humans is a disease caused by nematodes the genus Dirofilaria (Railliet et Henry, 1911). The role wild predators, particularly red fox (Vulpes vulpes) (Linnaeus, 1758) in distribution pathogen world remains unclear. We studied occurrence immitis (Leidy, 1856) population fox. Twenty-seven foxes were examined during winter hunting season 2019–2020 Dergachi district, ...
