transfusion-transmitted bacterial infectionAbbreviation: TTBI.
Illness in a transfusion recipient that develops after the infusion of contaminated blood or blood products, esp. platelets. It usually results from colonization of the blood product during handling or storage or, less frequently, from an unsuspected infection in the blood donor. Coagulase-negative staphylococci are often responsible. Other bacteria that sometimes cause TTBI include Pseudomonas species, Anaplasma, Babesia, and Rickettsia.Synonym: transfusion-associated bacterial infection
Viruses may also be transmitted from blood donors to transfusion recipients. They may include cytomegalovirus, encephalitis viruses, and, rarely, hepatitis viruses or human immunodeficiency virus.
