A multitude of microorganisms have been isolated from contaminated blood products. There is also a wide variation in the species of bacteria that are reported from different parts of the world. Some of these organisms and species include the following:

  • The Bacthem study, [3] BaCon study, [4] and SHOT program [5] found a similar range of microorganisms; isolates from the Bacthem study included YersiniaProteusPseudomonasEscherichiaKlebsiellaAcinetobacter, and Serratia, while among gram-positive organisms, PropionibacteriumStaphylococcusBacillus, and Enterococcus were isolated

  • The Japanese Red Cross reported Propionibacterium acnes as the most common bacterial contaminant [11]

  • Blood banks in Holland reported coagulase-negative staphylococci to be the most common bacteria isolated [12]

  • Some investigators have reported Yersinia enterocolitica as the most common isolate in TTBI; this organism is capable of growing and multiplying at low temperatures, which may increase its chances of survival during storage of blood products [13]
