Proliferative sparganosis in a cat.

C D Buergelt, E C Greiner, D F Senior

    The Journal of Parasitology
    |February 1, 1984
    PubMed
    Summary

    A domestic cat in Florida was diagnosed with proliferative sparganosis, a parasitic infection. Examination revealed unusual host cells and retrovirus-like particles within the parasite, suggesting a complex host-parasite interaction.

    Area of Science:

    • Veterinary Pathology
    • Parasitology
    • Infectious Diseases

    Background:

    • Sparganosis is a parasitic infection caused by tapeworm larvae (Spirometra spp.).
    • Domestic animals can serve as intermediate hosts for sparganosis.
    • Aberrant sparganosis cases require detailed pathobiological investigation.

    Observation:

    • A 6-year-old domestic cat from Florida presented with proliferative sparganosis.
    • Postmortem examination identified spargana and associated lesions in the stomach, spleen, and liver.
    • Microscopic analysis revealed unusual mononuclear cells within the spargana stroma.

    Findings:

    • The mononuclear cells were identified as host-derived monocytes.
    • Retrovirus-like particles were observed within the cytoplasm of some host monocytes.
    • This indicates a potential viral co-infection or a novel host response mechanism.

    Implications:

    • This case highlights the potential for complex host-parasite interactions in sparganosis.
    • The presence of retrovirus-like particles warrants further investigation into their origin and role.
    • Findings contribute to understanding aberrant parasitic infections in domestic animals.
