Unusual Parasite from Organ Donor Sickens 3 People

Three people who received organ transplants from the same donor all developed serious brain problems shortly after their operations. The mysterious symptoms turned out to be due to a little-understood parasite that infected the donor before she died, according to a new report of the case. Doctors were concerned that the man had contracted an infection from the donor, which happens in about 1 to 2 percent of U.S. transplants.
