Figure 4From: Inactivation of the fliY gene encoding a flagellar motor switch protein attenuates mobility and virulence of Leptospira interrogansstrain LaiColony sizes of the fliY-mutant and wild-type strain on semisolid Korthof agar. The colonies with different sizes formed by the fliY- mutant (A) and wild-type strain (B) on semisolid Korthof agar. The leptospires were cultured on 8% RS semisolid Korthof plate for three weeks. This experiment was repeated three times.Back to article page
