Haycocknema perplexum are parasitic nematodes which reside in tissue under the skin or in blood vessels.[1] The origin of their natural host is unknown. This group comprises 8% of nematode species affecting vertebrates.[1]

Clinical symptoms of haycocknema perplexum include eosinophilia and high levels of creatine kinase.[1] While rare, with only thirteen documented cases, all originating in Australia,[2] this parasite can become fatal if left untreated due to muscular dystrophy of the respiratory system.[1]
The first case was documented in 1998, and no cases in non-human animals have been reported as of 2022. Only one documented death from complications of infection has been recorded.[2]
The current treatment for the parasite is 400 mg of Albendazole.[3] The broad-spectrum anthelmintic drug can treat diseases by impairing the parasite's ability to absorb glucose, resulting in its death.[3]
