To analyze the distribution and drug resistance of pathogenic bacteria in diabetic patients with double J-stent associated infections, and to explore the strategies for prevention and treatment of the infections.
From January 2019 to December 2021, 266 diabetic patients treated with double J-stent placement in our hospital assessed for eligibility were recruited. Urine and double J-stent samples were collected for pathogenicity assay and screened for biofilm bacteria. Pathogenic bacteria distribution and drug resistance were examined.
A total of 97 strains (36.5%) of pathogenic bacteria were isolated from urine samples and 129 strains (48.5%) from double J-stent samples (P > 0.05). 3 strains (1.1%) of biofilm bacteria were separated from urine samples and 106 strains (39.8%) from double J-stent samples (P < 0.05). In the double J-stent samples, there were significantly higher ratios of Gram-positive bacteria separated from biofilm bacteria versus the urine-cultured pathogens (44.3%/61.3%, P < 0.05), and higher drug resistance was observed in biofilm bacteria versus urine-cultured pathogens (P < 0.05). Fosfomycin tromethamine showed remarkable susceptibility to both urinary cultured pathogens and double J-stent biofilm bacteria.
Diabetic patients with double J-stent biofilm-positive bacteria are mainly Gram-positive bacteria, which are prone to biofilm formation and show strong drug resistance.
分析双J管相关感染糖尿病患者病原菌分布及耐药情况,探讨感染防治策略。
选取2019年1月至2021年12月在我院行双J管置入术且符合入选标准的266例糖尿病患者。收集尿液及双J管样本进行病原菌检测及生物被膜菌筛查,检测病原菌分布及耐药情况。
尿液样本分离出病原菌97株(36.5%),双J管样本分离出129株(48.5%)(P>0.05)。尿液样本分离出生物被膜菌3株(1.1%),双J管样本分离出106株(39.8%)(P<0.05)。双J管样本中,生物被膜菌分离出的革兰阳性菌比例显著高于尿液培养病原菌(44.3%/61.3%,P<0.05),生物被膜菌耐药性高于尿液培养病原菌(P<0.05)。磷霉素氨丁三醇对尿液培养病原菌及双J管生物被膜菌均显示出显著敏感性。
双J管生物被膜阳性菌的糖尿病患者以革兰阳性菌为主,易形成生物被膜且耐药性强。
