Fig. 8From: Factors affecting use of ballistics gelatin in laboratory studies of bacterial contamination in projectile woundsFraction of survival of E. coli in buffer alone versus buffer and gelatin. Survival is calculated based on the initial survival of E. coli in its corresponding buffer alone. A significant difference in survival between PBS (buffer only) and PBS buffer plus ~ 1 ml of gelatin, and between M9 (buffer only) and M9 buffer plus 1 ml of gelatin (P < 0.005) was seenBack to article page
