Clostridium baratii: a rare case of pneumonia associated with an Alzheimer patient in Rio de Janeiro, Brazil

INTRODUCTION: Clostridium baratii is rarely associated with human diseases. Infection is usuallcaused by ingestion of contaminated food, and infant botulism is the most common clinical presentation.

Sumario:INTRODUCTION: Clostridium baratii is rarely associated with human diseases. Infection is usuallcaused by ingestion of contaminated food, and infant botulism is the most common clinical presentation. CASE REPORT: Here we report a case of pneumonia by a non-toxigenic strain of C. baratii in an Alzheimer 70-year-old male with sepsis in Rio de Janeiro, Brazil. The micro-organism was identified by phenotypical tests, mass spectrometry (MALDI-TOF), DNA amplification (PCR) and sequencing of the 16S rRNA gene. Testing for the presence of botulinum F toxin was made using multiplex PCR. Bioassay for a large number of colonies was performed in mice to evaluate the production of any lethal toxin, but the results were negative. CONCLUSION: To our knowledge, there are no cases of C. baratii infection reported in Brazil and we highlight the importance of anaerobic lab tests in the standard routine of diagnosis.
