Ochrobactrum anthropi as a Rare Cause of Catheter-Related Bloodstream Infection: A Case Report From Morocco

Ochrobactrum anthropi is a ubiquitous non-fermenting bacillus, rarely implicated in human infections. Reported infections are mostly catheter-related bacteremias, particularly in immunocompromised patients. We present what appears to be the first Moroccan case of catheter-related bloodstream infection associated with O. anthropi in a hemodialysis patient with underlying multiple myeloma. The diagnosis was confirmed by identification of the same organism from paired blood cultures, with a differential time to positivity indicating catheter involvement. Treatment included targeted antimicrobial therapy adjusted to renal function, along with catheter removal, which led to clinical improvement of the patient and negative follow-up cultures. This case emphasizes the importance of precise microbiological identification and reliable susceptibility testing to ensure proper management of the patient.
