title: [Bacterial contamination of platelet concentrates by Propionibacterium acnes].
abstract: In this study, three incidents of platelet contamination by Proprionibacterium acnes and an investigation of the transfusion process have been reported, which occurred at the Nord-Pas-de-Calais Blood Center over a period of several months. P. acnes is a bacterium that is present in the cutaneous flora; it does not produce any toxin, and is rarely considered as a pathogenic agent; its occurrence is widespread, in particular in those regions that are rich in sebum (face, back, scalp), and it is extremely apparent during adolescence. The three incidents occurred following the transfusion of a pool of leucodepleted platelet concentrates obtained from immunodeficient patients. The clinical outcome was in all cases positive. It was considered that the bacterial contamination of platelet concentrates could reflect insufficient skin disinfection at the site of the venipuncture and a minimal bacterial risk involving the blood collection procedure.
