Abstract OBJECTIVE To determinate the kin ds, counts and origins of bacteria in open fracture wounds. M ETHODS In randomly selected 160 open fracture wounds, bacter ia were tested qualitatively and quantatitively for 4～6 times in different tim e points during the patients were treated in the hospital. RES ULTS The kinds and counts of circumstance bacteria in open f racture wounds were inveshigated and the effacts of bacteria on the course of fr acture treatement were also observed. Gram-negative organisms including Pseudom onas and Enterobacteria were the most common strains, while the most common Gram -positive organisms were Stephytoxoccus epidermidis. CONCLUS IONS Bacteria contamination in open fracture wounds may be m anly hospital aquired and the common bacterio flora is Gram-negtive organisms.
