Identification of adenoviruses in specimens from high-risk pediatric stem cell transplant recipients and controls

Adenovirus infection is an important cause of morbidity and mortality in stem cell transplant recipients. We report species and type-specific analysis from a prospective study of high-risk adenovirus infections following hematopoietic progenitor cell transplantation prior to, during, and after treatment with cidofovir, as well as species analysis of contemporaneously collected samples from control patients. Nine different adenovirus types representing all six recognized species were identified, and mixed infections were commonly found in this group of patients.
