Caption:
This hematoxylin-eosin (H&E)-stained eye tissue specimen, revealed the presence of a Dirofilaria nematode, or roundworm. See PHIL 16428, 624, 625, and 16425, for sequentially greater magnifications of this parasitic invader. The genus Dirofilaria consists of many species that infect a wide range of hosts worldwide, including carnivores, rodents and primates. Humans are incidental hosts for several of these, acquiring Dirofilaria when bitten by mosquitoes (rarely black flies), the arthropod vector and intermediate host.
