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, [1] BaCon study, [2] and SHOT program [3] found a similar range of microorganisms; isolates from the Bacthem study included Yersinia, Proteus, Pseudomonas, Escherichia, Klebsiella, Acinetobacter, and Serratia, while among gram-positive organisms, Propionibacterium, Staphylococcus, Bacillus, and Enterococcus were isolated

  • The Japanese Red Cross reported Propionibacterium acnes as the most common bacterial contaminant [8]

  • Blood banks in Holland reported coagulase-negative staphylococci to be the most common bacteria isolated [9]

  • 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 [10]
