BackgroundDiabetic foot infection (DFI) is a common and serious complication of diabetes, which may lead to amputation, disability, and even death. Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major pathogens in DFI, and its prevalence is increasing. However, the pathogenic mechanism of MRSA in DFI remains unclear.2. ObjectivesThis study aims to investigate the status and pathogenic genes of MRSA in DFI, to provide theoretical and practical guidance for the prevention and treatment of DFI.3. MethodsThe study will be conducted in two phases:Phase 1: Clinical investigation- Collect bacterial samples from DFI patients with suspected MRSA infection- Perform bacterial identification and antimicrobial susceptibility testing- Analyze the clinical and laboratory data of the patients, including demographic characteristics, risk factors, and outcomes- Compare the characteristics and outcomes of MRSA-positive and MRSA-negative DFI patientsPhase 2: Pathogenic gene analysis- Extract genomic DNA from MRSA isolates- Perform whole-genome sequencing and assembly- Analyze the differential gene expression and polymorphisms of MRSA isolates from DFI patients and other sources- Screen for virulence genes and functional pathways related to MRSA pathogenesis in DFI4. Expected outcomesThe study is expected to provide the following outcomes:- A clear understanding of the prevalence and characteristics of MRSA in DFI精品文档---下载后可任意编辑- Identification of potential risk factors and predictors for MRSA infection in DFI patients- Identification of specific virulence genes and functional pathways involved in MRSA pathogenesis in DFI- Provision of theoretical and practical guidance for the prevention and treatment of DFI caused by MRSA5. ConclusionThis study will contribute to the understanding of MRSA in DFI and provide a basis for the development of effective preventive and therapeutic strategies for DFI.
