Transfusion-transmitted babesiosis in Washington State : First reported case caused by a WA1-type parasite.
Annual meeting, American Society of Tropical Medicine and Hygiene. Baltimore (USA), 1996/12.
Most cases of babesiosis reported in the United States have been tickborne and caused by Babesia microti, the etiologic agent of all previously described transfusion-transmitted cases.
A 76-year-old man with the first recognized case of transfusion-transmitted infection with the recently identified WA1-type Babesia parasite is described.
The subject received multiple blood transfusions in 1994.
Indirect immunofluorescent antibody testing of serum from 57 blood donors implicated a 34-year-old man (WA1 titer, 1 : 65,536) whose donation had been used for packed red cells.
Isolates of the organisms that infected the recipient and the donor, both of whom were spleen-intact residents of Washington State, were obtained by hamster inoculation.
The DNA sequence of a 536-bp region of the nuclear small subunit-rRNA gene of both isolates was identical to that of WA1 (isolated in 1991 from the index WA1 case-patient).
Effective measures for preventing transmission of babesiosis by blood transfusion are needed.
