Four ball pythons died from anorexia due to severe hemorrhagic colitis. Microscopic examination revealed amoeba-like protozoa, likely Entamoeba invadens, infecting the large intestine.

Area of Science:

  • Veterinary Pathology
  • Parasitology

Background:

  • Ball pythons (Python regius) are popular exotic pets.
  • Colitis is a common gastrointestinal issue in reptiles.

Observation:

  • Four ball pythons in a single display exhibited anorexia and mortality over a two-month period.
  • Necropsy revealed severe hemorrhagic and necrotizing colitis in all affected snakes.

Findings:

  • Microscopic analysis identified amoeba-like protozoa within the colonic tissue.
  • These protozoa displayed macrophage-like morphology and formed thick-walled cysts.
  • Infection was localized throughout the large intestine wall.

Implications:

  • The findings suggest Entamoeba sp. infection, likely Entamoeba invadens, as the cause of the fatal colitis.

  • This highlights the pathogenic potential of Entamoeba invadens in ball pythons.
  • Accurate diagnosis and management of reptilian amoebiasis are crucial for preventing mortality.
