Biofilm formation ability of
strains and CLSM images of biofilms. A shows the biofilm formation ability evaluated by crystal violet staining using 96-well plates; B and C show the three-dimensional features of biofilms formed by strains NJPK1406 and GD201008-001, respectively. ##
P < 0.01 indicates a significant difference compared between subgroup ST67 and other two subgroups. **
P < 0.01 indicates a significant difference compared to bovine group.
