This study will examine bacteria in patients mouths at different times during stem cell transplantation and recovery. Drugs patients receive as part of the conditioning process for a stem cell transplant increase their risk of infection. There might be a link between the bacteria in the mouth and the bacteria that can cause infections. Knowing the changes in bacteria might help researchers determine the best method to prevent infections. Patients 18 years of age and older who are scheduled to receive a stem cell transplant may be eligible for this study. Participants undergo the following procedures: Review of medical records Interview about their oral care Oral examination Collection of oral specimens just before the stem cell transplant, immediately after the transplant, and 3 weeks after the transplant. The specimens are obtained as follows:
