Three patients with Australian parasitic myositis caused by the muspiceoid nematode Haycocknema perplexum are described. Treatment with albendazole led to a slow and incomplete recovery, but treatment with steroids caused life-threatening deterioration. 
Haycocknema perplexum: an emerging cause of parasitic myositis in Australia.
This case involved an 80-year-old Queensland wildlife carer, who presented with muscle weakness, mild eosinophilia and creatine kinase elevation, which supports an association with native animal contact and highlights the debilitating nature of this infection. Expand
Using PCR-Based Sequencing to Diagnose Haycocknema perplexum Infection in Human Myositis Case, Australia
A new, nested PCR–coupled sequencing method enabled the unequivocal diagnosis of myositis caused by the enigmatic nematode Haycocknema perplexum in a male patient in Australia. Expand

New cases of disseminated myositis in two male patients from the states of Queensland and Tasmania in Australia are reported; genetically characterize the causative agent from each case; and a PCR-based sequencing approach is established as a tool to support the diagnosis of future cases and to underpin epidemiological studies.

A further patient with parasitic myositis due to Haycocknema perplexum, a rare entity
This uniquely Australian parasite can mimic polymyositis and leads to significant irreversible morbidity and even mortality (one died), if diagnosed late or after corticosteroids. Expand
Parasitic infections and myositis
The diagnosis of parasitic myositis is suggested by the clinical picture and radiologic imaging, and the etiologic agent is confirmed by parasitologic, serologic, and molecular methods, together with histopathologic examination of tissue biopsies. Expand

Nonbacterial Myositis
Treatment of infectious myositis entails antimicrobial agents against the pathogen, with consideration for surgical drainage for focal purulent collections within the musculature. Expand
Bacterial, Fungal, Parasitic, and Viral Myositis
Infectious myositis may be caused by a broad range of bacterial, fungal, parasitic, and viral agents and therapy is based on the clinical presentation and the underlying pathogen. Expand

Polymyositis caused by a new genus of nematode
The infecting nematode appears to belong to a new genus and is the first known muspiceoid nematodes to infect humans, and its life cycle and the route of infection are unknown. Expand
Aspects of the life history of Muspicea borreli (Nematoda: Muspiceidae), parasite of the house mouse (Mus domesticus) in Australia.
Experimental infection of BALB/c mice indicates that larvae develop to the infective stage in the uterus of the adult worm, suggests that an obligate developmental phase on the host skin does not occur and that autoinfection is possible. Expand
Haycocknema perplexum n. g., n. sp. (Nematoda: Robertdollfusidae): an intramyofibre parasite in man
Haycocknema perplexum n. g., n. sp. (Nematoda: Robertdollfusidae) is described from a man in Tasmania, Australia. Adult male and female nematodes and larvae were recovered from myofibres followingExpand
Durikainema phascolarcti n. sp. (Nematoda: Muspiceoidea: Robertdollfusidae) from the pulmonary arteries of the koala Phascolarctos cinereus with associated pathological changes
Some individual transverse sections of these pulmonary vessels contained as many as 135 sections of nematode occupying >95% of the diameter of the vessel, suggesting levels of infection in these important vessels probably compromise respiration and circulation, and affect the health of the animal.

Durikainema macropi gen. et sp. nov. (Muspiceoidea: Robertdollfusidae). A remarkable nematode from Macropodidae (Marsupialia).
The new genus Durikainema is described from the mesenteric and hepatic portal veins of Macropus giganteus Shaw 1790, M. agilis (Gould 1842) and M. rufogriseus (Desmarest 1817) (Marsupialia: Macropodidae) from Queensland, Australia. Expand

A range of organisms normally occurring in wildlife, domestic animals or the environment may be involved in causing human disease and food chains occurring in a range of Australian ecosystems and environments, some associated with feeding arthropods, others with accidental ingestion of invertebrates, may result in human exposure and infection.
