Silver resistance in <i>Pseudomonas aeruginosa</i> and <i>Acinetobacter baumannii</i> isolated from burn patients

Introduction: Burn infections are a serious obstacle to the patient’s recovery. Infection is estimated account for 75% of burn patient mortality. Widespread and often indiscriminate administration antibiotics lack basic infection control methods major factors in emergence drug-resistant bacteria. Due growing threat antibiotic resistance, interest silver compounds has grown modern medicine. Objectives: The aim this descriptive study was evaluate frequency sil genes its phenotypic expression Pseudomonas aeruginosa Acinetobacter baumannii isolates isolated from ward Imam Khomeini hospital Urmia. Patients Methods: P. (n=16) A. (n=32) were collected wound samples an 8-month period August March 2017 hospital. minimum inhibitory concentration nitrate on clinical determined using microdilution method. presence silP, silE silS resistance investigated by polymerase chain reaction (PCR). Results: results (MIC) test showed that 62.5% (n = 10) 56.25% 18) MIC above 512 mg/ml. Polymerase revealed only one isolate had gene among isolates, 20 six gene. None positive silP Conclusion: Based results, most common microorganism wounds our This high degree which also observed some isolates.
