Disease relevance of icaA

  • All Staphylococcus aureus prosthetic joint infection isolates (n = 55) were icaA positive [1].
  • To assess the clinical impact of PIA production, isolates from 15 prospectively identified cases of S. aureus bacteremia in patients with prosthetic joints (8 infected, 7 uninfected) were characterized for biofilm production, hemagglutination, and the presence of a 419-bp amplification product within icaA [2].
  • The objectives of the study were to examine in vitro slime production, biofilm formation, and the presence of the ica gene locus and icaA and icaD genes in S. aureus isolates from bovine mastitis [3].
