FIG. 2.
Growth curves of four units of AS-3 red blood cells inoculated with S. liqueifaciens (two units inoculated to 4.2 CFU/ml) and Y. enterocolitica (two units inoculated to 11.6 CFU/ml) (5a). Bacteria were not detectable by culture until days 3 to 6. Isolates were from strains actually implicated in post-red-blood-cell-transfusion sepsis (the isolates were kindly provided by M. Arduino, Centers for Disease Control and Prevention, Atlanta, Ga.).
