[Clinical and ultrastructural study of a case of human rabies]
Abstract:
A patient of Morracan origin, aged 26 years, who died as a result of rabies after a 15 day illness in August 1976 in Bordeaux. No evidence of contamination was found by history from the patient and his family and friends nor by examination. A cerebral biopsy carried out a few hours before death confirmed the diagnosis by immunofluorescence, whilst examination under the optical microscope demonstrated Negri bodies and ultrastructural studies revealed rabies virus. These findings are discussed and compared with a few other cases reported in the literature with electron microscope studies.
Insights
A 26-year-old Moroccan patient died from rabies despite no clear contamination source. Diagnosis was confirmed via cerebral biopsy showing Negri bodies and rabies virus via electron microscopy.
Area of Science:
- Neurology
- Virology
- Pathology
Background:
- Rabies is a fatal viral disease affecting the central nervous system.
- Diagnosis can be challenging, especially in cases with unclear exposure history.
Observation:
- A 26-year-old patient of Moroccan origin presented with a 15-day illness culminating in death.
- Clinical history and initial examinations revealed no evidence of rabies exposure.
- A cerebral biopsy was performed shortly before the patient's demise.
Findings:
- Immunofluorescence of the cerebral biopsy confirmed rabies diagnosis.
- Optical microscopy revealed characteristic Negri bodies within the brain tissue.
- Ultrastructural studies definitively identified the presence of rabies virus particles.
Implications:
- This case highlights the importance of considering rabies even without a known exposure history.
- Electron microscopy provides crucial ultrastructural evidence for rabies virus identification.
- Comparing findings with existing literature aids in understanding rabies pathogenesis and diagnosis.
