Table 4 Prevalence of the Biofilm-associated genes and IS elements (IS256 and IS257) among the strong (n = 38), moderate (n = 38), and weak (n = 31) biofilm producers. P1: p-value between strong biofilm and moderate biofilm isolates. P2: p-value between strong biofilm and weak biofilm isolates. P3: p-value between moderate biofilm and weak biofilm isolates
