title: Comparison of the adherence of E.Coli and S. Aureus to ten different prosthetic mesh grafts: In vitro experimental study.
abstract: BACKGROUND
  The prosthetic mesh grafts used to repair the abdominal wall may become infected, primarily by S. aureus and E. coli. This study sought to provide a rational basis for the choice of mesh used to repair a hernia when there is a likelihood of infection or contamination.
  
  
  METHODS
  S. aureus and E. coli were incubated with ten types of prosthetic mesh graft (Table 1) in liquid growth medium. After sequential dilution of samples from the prosthetic mesh grafts, the colony forming units of adherent S. aureus and E. coli were counted.
  
  
  RESULTS
  There was no significant difference in the numbers of E. coli and S. aureus adherent to simple polypropylene mesh grafts. Significantly more of both species were adherent to the polyester, expanded polytetrafluoroethylene (ePTFE), and composite prosthetic mesh grafts, except for E. coli on graft 5. Significantly fewer E. coli were adherent to composite mesh grafts 5, 8, and 10 than S. aureus.
  
  
  CONCLUSIONS
  S. aureus and E. coli adhere to polypropylene similarly. In vitro, fewer S. aureus and E. coli adhere to simple polypropylene mesh grafts than to polyester, ePTFE, or composite prosthetic mesh grafts.
