Abstract
A case of human intraocular dirofilariasis is reported from northern Brazil. The nematode was morphologically and phylogenetically related to Dirofilaria immitis but distinct from reference sequences, including those of D. immitis infesting dogs in the same area. A zoonotic Dirofilaria species infesting wild mammals in Brazil and its implications are discussed.
Highlights
A case of human intraocular dirofilariasis is reported from northern Brazil
We report a case of human intraocular dirofilariasis in which a live male Dirofilaria sp. worm was recovered from the anterior chamber of a patient’s eye
Morphologic and molecular studies suggested that this zoonotic case of dirofilariasis was caused by a Dirofilaria sp. closely related to D. immitis
Summary
A case of human intraocular dirofilariasis is reported from northern Brazil. The nematode was morphologically and phylogenetically related to Dirofilaria immitis but distinct from reference sequences, including those of D. immitis infesting dogs in the same area. Twenty-eight cases of human dirofilariasis in the Old World attributed to D. immitis have been reviewed recently and attributed to D. repens (5). We report a case of human intraocular dirofilariasis in which a live male Dirofilaria sp. Morphologic and molecular studies suggested that this zoonotic case of dirofilariasis was caused by a Dirofilaria sp.
