Acute filariasis in a springhaas

R C Anderson1, B W Gustafson, E S Williams

  • 1Department of Zoology, University of Guelph, Ontario, Canada.

Journal of Wildlife Diseases

Summary

A Springhaas imported to the USA developed severe illness due to aberrant migrations of Filaria versterae nematodes. Lung invasion caused fatal respiratory distress, prompting euthanasia and a redescription of the parasite.

Area of Science:

  • Veterinary Parasitology
  • Zoological Medicine
  • Nematology

Background:

  • Filaria versterae nematodes typically parasitize subcutaneous tissues of Springhaas (Pedetes capensis) in their native South Africa.
  • Aberrant migration of these nematodes can lead to severe clinical disease in hosts.

Observation:

  • A 2-year-old Springhaas imported to the USA presented with severe debilitation.
  • Parasitological examination revealed extensive migration of adult Filaria versterae beyond typical subcutaneous locations.

Findings:

  • Nematodes invaded multiple internal body cavities, including the peritoneal and thoracic cavities, pericardial sac, and lungs.
  • Pulmonary invasion by Filaria versterae caused life-threatening respiratory distress, leading to euthanasia of the animal.
  • The Filaria versterae parasite was redescribed based on this case.

Implications:

  • This case highlights the potential for parasitic diseases to cause severe pathology in exotic animals following importation.
  • Understanding aberrant parasite migration is crucial for diagnosing and managing parasitic infections in wildlife and zoological collections.
  • The redescription of Filaria versterae provides valuable taxonomic and diagnostic information for veterinary parasitologists.
