A Post-Operative Infection Caused by Bacillus circulans and Paenibacillus macerans in a Patient with Brain Tumour

We report a case of post-operative infection due to rarely isolated bacteria - Bacillus circulans and Paenibacillus macerans - in a 49-year-old woman following resection of a tuberculum sellae meningioma. The two bacterial pathogens were isolated from a cerebrospinal fluid specimen. These bacteria are opportunistic pathogens, which have often been ruled out as culture contaminants when isolated from clinical material.
