Figure 2From: The paratransgenic sand fly: A platform for control of Leishmania transmissionPlasmid stability of transformed B. subtilis in larval chow. The viability of the transformed cells shows a steady decline in larval chow. At the end of the two-week experimental period, close to 40% of the remaining viable B. subtilis no longer confer antibiotic resistance, suggesting plasmid loss.Back to article page
