title: Recurrent Ochrobactrum anthropi and Shewanella putrefaciens bloodstream infection complicating hemodialysis.
abstract: Bloodstream infections (BSIs) are common in hemodialysis, especially when the access is a catheter. These infections are more commonly gram-positive bacteria or gram-negative bacilli and on some occasions, fungi. Ochrobactrum anthropi and Shewanella putrefaciens are ubiquitous hydrophilic gram-negative bacilli. There have been three cases of O. anthropi BSI reported in hemodialysis patients (one from the United States and two from Vienna) and two cases of S. putrefaciens BSI in hemodialysis patients (one from the United States and the other from Japan). There have been few more cases reported of infections with these bacteria in peritoneal dialysis, especially outside the United States. We present a novel case of a patient with both recurrent O. anthropi and S. putrefaciens BSI complicating hemodialysis. There have been no reports in the literature of such a case. We also discuss the microbiology, clinical features, and the challenging aspects of treatment of such infections.
