[Generalized protothecosis in a fruit bat (Pteropus lylei)]
Abstract:
Prototheca organisms, histologically resembling Prototheca wickerhamii, were found in a fruit bat as a cause of a massive granulomatous lymphadenitis and splenitis and a widespread granulomatous meningoencephalitis. Focal lesions were also present in the myocardium, in skeletal muscles, and in the kidneys.
Insights
Prototheca organisms caused severe granulomatous inflammation in a fruit bat, affecting lymph nodes, spleen, and brain. Lesions were also found in the heart, muscles, and kidneys.
Area of Science:
- Veterinary Pathology
- Mycology
- Infectious Diseases
Context:
- Prototheca species are achlorophyllous algae that can cause opportunistic infections in various hosts.
- Fruit bats are known reservoirs for diverse pathogens, but Prototheca infections are rarely documented in these animals.
Purpose:
- To report a novel case of Prototheca infection in a fruit bat.
- To describe the pathological findings associated with this infection.
Summary:
- Histopathological examination revealed Prototheca organisms, consistent with Prototheca wickerhamii, in a fruit bat.
- The infection resulted in severe granulomatous lymphadenitis, splenitis, and meningoencephalitis.
- Focal granulomatous lesions were also identified in the myocardium, skeletal muscles, and kidneys.
Impact:
- This case expands the known host range for Prototheca infections.
- It highlights the potential for Prototheca to cause significant systemic disease in chiropterans.
- Further investigation into Prototheca epidemiology in bats is warranted.
