All of the patients in Table 4 were serologically negative at time of transplant and none sero-converted during the time they were monitored at CDC.

BC = buffy coat; only the buffy coat fraction was PCR positive for these samples.

†: indicate specimens that were collected during drug treatment (benznidazole or nifurtimox). Drug treatment information is missing for patients #4 and #9.
