Summary
A parasitic infection caused fatal intestinal bleeding in grey kangaroos imported from Australia. Histopathology revealed parasites reproducing within intestinal glandular cells, leading to tissue destruction and death.
Area of Science:
- Veterinary Pathology
- Parasitology
- Wildlife Health
Background:
- Grey kangaroos were imported from Australia in July 1974.
- The kangaroos died within one month of arrival due to severe intestinal bleeding.
Purpose of the Study:
- To investigate the cause of death in imported grey kangaroos.
- To characterize the histopathological findings and identify the causative agent.
Main Methods:
- Necropsy and biopsy of affected kangaroos.
- Histopathological examination of intestinal tissues.
- Spectrophotometry and fluorometry to measure parasite nucleic acid content.
Main Results:
- Intestinal epithelium showed necrotic degeneration and bleeding from stomach to jejunum.
- Swollen glandular cells formed giant cells containing parasites within cysts.
- Parasites were observed migrating into host cell cytoplasm and nucleus, with stages resembling tachyzoites.
Conclusions:
- The study identified a parasitic reproduction cycle within the intestinal glandular cells of the kangaroos.
- This parasitic infection is the likely cause of the fatal intestinal bleeding and death.
