String test for hypermucoviscosity (HV) in the KP-M1 strain of Klebsiella pneumoniae. (A) Each closed bar indicates the mean ± standard deviation in millimeters for the results of string tests among KP-M1 organisms treated with various concentrations of sodium salicylate (SAL) as indicated. The asterisk indicates the significant changes among the results with different SAL concentrations (p < 0.01). (B) Representative photographs of the stretched, mucoviscous string from single colonies of KP-M1 organisms treated with various concentrations of SAL as indicated.
