Presence of indwelling catheters is also a potential risk factor for <jats:italic>M. aurum<\/jats:italic> infection. No case report has been documented in the literature regarding the pathogenic potential of <jats:italic>M. aurum<\/jats:italic> in causing bacteremia. This is the first case series reporting bacteremia by <jats:italic>M. aurum<\/jats:italic> describing the risk factors and sensitivity pattern of this pathogen. In this case series, we have described bacteremia caused by <jats:italic>M. aurum.<\/jats:italic> The risk factors and sensitivity pattern of this pathogen have also been evaluated. Here, we describe the clinical course and presentation of three patients whose blood culture showed growth of <jats:italic>M. aurum.<\/jats:italic> Indwelling venous catheter for hemodialysis or for chemotherapy for the treatment of acute lymphoblastic leukemia was found to be a risk factor in two patients. Rheumatoid arthritis was the underlying condition in the second patient and was started on immunosuppressants. Blood samples were collected during the febrile period. The blood culture samples of all these patients had pure isolates of <jats:italic>M. aurum<\/jats:italic>, identified by matrix-assisted laser desorption ionization\u2013time of flight mass spectrometry. All three patients were managed according to the sensitivity reports and were discharged in stable condition.<\/jats:p>","DOI":"10.4269\/ajtmh.23-0701","type":"journal-article","created":{"date-parts":[[2024,7,3]],"date-time":"2024-07-03T13:34:43Z","timestamp":1720013683000},"page":"132-135","source":"Crossref","is-referenced-by-count":2,"title":["Case
