Summary
Systemic toxoplasmosis caused by Toxoplasma gondii was diagnosed in two captive flying-foxes. This is the first report of this disease in megachiropteran bats, highlighting potential risks in captivity.
Area of Science:
- Veterinary Pathology
- Parasitology
- Wildlife Health
Background:
- Toxoplasma gondii is an opportunistic protozoan parasite with a wide host range.
- Systemic and neurological diseases are significant causes of mortality in captive wildlife.
Observation:
- Two juvenile flying-foxes (Pteropus conspicillatus and P. scapulatus) presented with respiratory distress and, in one case, neurological signs.
- Necropsy and diagnostic testing confirmed systemic toxoplasmosis in both animals.
Findings:
- This study reports the first documented cases of systemic toxoplasmosis in megachiropteran bats.
- Toxoplasma gondii infection was identified as the cause of death in these flying-foxes.
Implications:
- This finding expands the known hosts for Toxoplasma gondii to include megachiropteran bats.
- Toxoplasmosis should be considered in the differential diagnosis for systemic and neurological diseases in captive flying-foxes.
- The role of captivity in disease development and exposure warrants further investigation.
