Haycocknema perplexum are parasitic nematodes which reside in tissue under the skin or in blood vessels.

[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.

[3] The broad-spectrum anthelmintic drug can treat diseases by impairing the parasite's ability to absorb glucose, resulting in its death.
