Figure 3. Comparison of morphological and structural features of the S. Derby D1 parental and potR mutant strains.

Figure 3

Comparison of S. Derby D1 (left) and mutant strain S. Derby D1 ΔpotR::kan (right). (a) Strains were photographed after 2 hours remaining static post 16 hours of culturing at 37°C with agitation at 220 rpm. (b) Negative electron microscopy performed after 16 hours of culturing at 37°C with agitation at 220 rpm. Pili on the mutant and type-1 fimbriae on the parental strain are marked by arrows. (c) Strains were plated on to LB agar plates and incubated for 16 hours at 37°C.
