5% Fructose solution in a pot, given orally to neonates, was found to be contaminated with Acinetobacter calcoaceticus. This contamination was due to continuous use of the pot without disinfection. The following facts were noted:(1) The contamination level of 5 % fructose solution always reached to the order as high as 104 colony forming units/ml immediately before 24-hourly replacement;(2) 10% Fructose solution for injection and distilled hot water for preparation of 5 % Fructose solution were not contaminated;(3) 5 %-Fructose solution supported the growth of the bacilli; that fact was confirmed by challenging test.
It was suggested that the bacilli present in residue of 5 % fructose solution in the empty pot should have multiplied in the freshly refilled solution.
