A Case of Adult Intestinal Toxemia Botulism During Prolonged Hospitalization in an Allogeneic Hematopoietic Cell Transplant Recipient.

We report a laboratory-confirmed case of adult intestinal toxemia botulism in an allogeneic hematopoietic stem cell transplantation (allo-HCT) recipient. Onset of symptoms occurred within the hospitalized setting, making this case particularly unique. Botulism may have arisen because of significant intestinal disruption and compromise, and not directly from immune compromise.
