Effect of deletion of dotU gene from A. veronii on its growth, haemolytic activity and colony morphology. a Growth curves of wild-type strain TH0426, mutant strain ∆dotU and complemented strain C-dotU in LB at 30 °C with growth monitored by OD600. Values are showed as means ± standard deviations (SD) from as least three independent experiments. b Effect of dotU gene on haemolytic activity of A. veronii. c Changes in the surface morphology of colonies of the parental strain TH0426, mutant strain ∆dotU and complemented strain C-dotU
