Dog lungworm, SEM
Coloured scanning electron micrograph (SEM) of a dog lungworm (Angiostrongylus vasorum) Also known as the French heartworm, this is a common filarial nematode parasite of dogs and rarely humans. The adult worms are large, measuring up to 25 centimetres long, and they typically live in the dog's right heart and pulmonary artery. It causes the disease canine angiostrongylosis in dogs. Female worms produce microfilariae that are found in the dog's blood and can be ingested by mosquitoes. The microfilariae mature into infective juveniles in the mosquito and the infection is transmitted to a new host when the mosquito feeds such as dogs and humans. The natural intermediate hosts of Angiostrongylus vasorum are land slugs, land snails and freshwater snails. Magnification: x80 when shortest axis printed at 25 millimetres.
