WebThe results revealed strong, moderate, and weak attachment abilities related to biofilm formation attributes in 45%, 20%, and 35% of strains, respectively. In the meantime, the frequency of the fimH, afa, and kpsMSTII genes among the isolates was observed as follows: fimH positive: 65%; afa positive: 55%; and kpsMSTII positive: 85%. WebMicro-topography, bacterial attachment and biofilm formation Based on the screening data obtained from quantification of P. aeruginosa and S. aureus attachment to PS TUs, hit topographies (“anti-attachment TUs”) with a 5 to 20-fold reduction in bacterial attachment compared with the flat control surface were chosen for further studies.
