Optimal time for routine early subculture of blood cultures

Abstract
Routine aerobic subcultures [to detect bacterial infections in humans] performed between 6 and 12 h and between 12 and 17 h after blood collection yielded 36 and 63%, respectively, of isolates from blood cultures, while only 10% of isolates were recovered in a preliminary study when cultures were subcultured within 6 h of blood collection for cultures.
