Summary
Prototheca algae can cause severe infections in immunocompromised individuals, mimicking other illnesses. This case highlights diagnostic challenges in a fatal cardiac transplant recipient infection.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Transplant Medicine
Background:
- Prototheca species are ubiquitous environmental algae.
- Algal infections (protothecosis) are rare but can be severe in immunocompromised hosts.
- Clinical presentation of protothecosis can be non-specific, mimicking other conditions.
Observation:
- A 78-year-old cardiac transplant recipient developed a fatal infection.
- The patient's clinical manifestations were atypical and challenging to diagnose.
- Diagnostic pitfalls occurred in both clinical assessment and laboratory identification.
Findings:
- The case involved a fatal Prototheca species infection.
- Misdiagnosis or delayed diagnosis contributed to the adverse outcome.
- Specific diagnostic challenges related to Prototheca identification were encountered.
Implications:
- Highlights the importance of considering rare pathogens like Prototheca in immunocompromised patients.
- Underscores the need for improved diagnostic strategies for algal infections.
- Emphasizes the critical role of timely and accurate laboratory identification in managing complex infections.
