Bloodstream infection caused by mycobacterium abscessus
Abstract
Rapidly growing mycobacteria including M. abscessus complex are normal environmental inhabitants and may become opportunistic pathogens especially in immunosuppressed hosts. We report a bloodstream infection case caused by M. abscessus in a 10 year-old female patient with stage IV neuroblastoma diagnosis. After isolation of microorganism from blood culture bottle, the microorganism was identified by matrix assisted laser desorption ionization time-of-flight mass spectrometry and BD Phoenix automated identification and drug susceptibility device. Clarithromycin was added to her current antibiotic therapy and the patient was discharged with recovery. Non-tuberculosis mycobacteria are becoming serious opportunistic pathogens, physicians must take these microorganisms under consideration for especially immunosuppressed patients. Due to wide diversity of antimicrobial resistance patterns, species level identification is crucial.
