Organ transplant patients develop nematode infection

This follows a case in which three of four patients receiving organs from a single donor in Pennsylvania developed infection, and one died. The donor regularly visited Puerto Rico.

Most Strongyloides infections in organ transplant recipients are believed to be caused by reactivation of infection after initiation of immunosuppressive therapy. The incidence of donor-derived infection is unknown.

Guidelines call for recipient screening but the new case suggested donors should also be tested, the CDC officers said.
