Fig. 2From: Phenotypic and genetic changes in the life cycle of small colony variants of Salmonella enterica serotype Typhimurium induced by streptomycinBiofilm production of WT (wide-type; strain 5) and SCVs (strain 1024-4 and 1024-5). a A 3D projection of a biofilm structure of SCVs obtained by CLSM. b Ability of biofilm formation by using substratum coverage. c Ability of biofilm formation based on crystal violet assay. Data are presented as mean ± SD. Different letters on the error bars indicate statistically significant differences between strains in each group based on ANOVA (P < 0.01)Back to article page
