S. aureus, burn, Ag NPs, MIC, fnbA gene


: The purpose of the recent study was to profile of biofilm formation gene (fnbA) in S.
aureus which isolated from burn patients, and to detect the antibacterial activity and MICs of
silver nanoparticles against pathogenic S. aureus isolated from burn wounds. One hundred and
sixty samples from burn patients were collected from August to October 2023 in a burn center in
the Thi-Qar province of Iraq. The S. aureus was only identified in (35; 21.90%) isolates.
Microscopical examination, morphological characterization, diverse biochemical testes, were
used to recognize S. aureus isolates. The PCR technique results recorded that 42.8% of S. aureus
isolates had the fnbA gene. The Ag NPs had antibacterial activity against completely S. aureus
