INTERCEPT Blood System for Platelets
Pathogen Inactivation Data: Bacteria

The INTERCEPT Blood System for platelets has been shown to inactivate a variety of bacteria in platelet products. Inactivation studies using a range of gram positive and gram negative pathogenic bacteria demonstrated inactivation of approximately 6 logs of organisms, with the exception of P. aeruginosa and B. cereus (including spores), which showed reductions of 4.5 and 3.6 logs, respectively. Bacterial spores are resistant to inactivation; however, spore-forming bacteria in the vegetative state are sensitive to inactivation. The results of these studies are summarized below:

 

Bacterial Species Tested Using the INTERCEPT Blood System for Platelets Extent of Inactivation*

Escherichia coli >6.4
Serratia marcescens >6.7
Klebsiella pneumoniae >5.6
Pseudomonas aeruginosa 4.5
Salmonella choleraesuis >6.2
Yersinia enterocolitica >5.9
Enterobacter cloacae 5.9
Gram-Positive Bacteria  
Staphylococcus epidermidis >6.6
Staphylococcus aureus 6.6
Streptococcus pyogenes >6.8
Listeria monocytogenes >6.3
Corynebacterium minutissimum >6.3
Bacillus cereus (includes spores) 3.6
Bacillus cereus (vegetative) >6.0
Bifidobacterium adolescentis >6.5
Propionibacterium acnes >6.7
Lactobacillus species >6.9
Clostridium perfringens (vegetative form) >7.0
Spirochete Bacteria  
Treponema pallidum ≥6.8 to ≤7.0
Borrelia burgdorferi >6.8
* “>” refers to inactivation below the limit of detection of the assay
