Reducing Bacterial Contamination in Blood Components

Bacterial contamination of fresh blood components is the most prevalent transfusion-associated infectious risk, and platelet concentrates (PCs) are the blood product most likely to be infected. Dr. Ramirez’ applied research projects further our understanding of contamination of fresh blood components and stem cell products and help develop better methodologies for bacterial detection.

Why is this important?

Dr. Ramirez’ research on detection of bacterial growth in blood and stem cell products contributes to the distribution of safer blood products for Canadian patients.

Dynamics of Bacterial Growth and Biofilm Formation in Blood Products

Dr. Ramirez' team has developed extensive expertise around bacteria forming surface-attached aggregates known as biofilms. The formation of such biofilms is associated with increased pathogenicity and might explain instances of missed bacterial detection in blood components.

Why is this important?

Biofilm formation is a serious hurdle for the detection and elimination of bacterial contamination of blood products. Dr. Ramirez’ work informs efforts to prevent contamination from these bacteria and improve their detection, at every step from skin disinfection before donation to testing our final products.
