However, despite the loss of the ica operon by the ST71-like isolates there was no significant difference between typical CC97 isolates and ST71-like isolates in their ability to form a biofilm in TSB (P = 0.88) or TSB + 4% NaCl (P = 1) while the difference in TSB + 1% glucose approached significance (P = 0.07).
