| [摘要]目的：分析我院1~3月龄住院婴儿感染的病原菌分布及多重耐药情况。方法：回顾性收集2015年1月至2019年6月在我院小婴儿病区住院的1~3月龄感染婴儿的各类标本，统计分析病原菌及多重耐药菌的检出率等。结果：共收集送检标本23 217份，3 531份（15.2%）检出病原菌，阳性标本主要是痰培养标本（3 284份）和血培养标本（178份），各年度病原菌检出率分别为2015年8.3%、2016年13.3%、2017年15.8%、2018年18.1%，逐年升高（P<0.05）。检出率排名前5位的病原菌依次为流感嗜血杆菌、金黄色葡萄球菌、大肠埃希菌、肺炎克雷伯菌、卡他莫拉菌；排名前5位的多重耐药菌依次为产超广谱β-内酰胺酶菌株、耐甲氧西林金黄色葡萄球菌、碳青霉烯类耐药肠杆菌、耐甲氧西林凝固酶阴性葡萄球菌、耐甲氧西林表皮葡萄球菌，各年度这5种多重耐药菌总检出率分别为2015年3.0%、2016年3.7%、2017年3.2%、2018年2.9%，差异无统计学意义（P>0.05）。结论：我院小婴儿病区感染送检标本主要是痰培养标本，病原菌检出率逐年上升，以革兰阴性菌为主，存在多重耐药现象。 |

| Abstract: |
| [Abstract] Objective: To analyze the distribution of pathogens and multidrug-resistant organisms in hospitalized infants aged from 1 to 3 months in our hospital. Methods: Retrospective analysis was performed on all kinds of specimens from infected infants aged from 1 to 3 months who were admitted into infant ward of our hospital from Jan. 2015 to Jun. 2019. The detection rates of pathogens and multidrug-resistant organisms were statistically analyzed. Results: A total of 23,217 specimens were collected and sent for examination, 3,531 (15.2%) pathogens were detected, and the positive specimens were mainly sputum culture specimens (3,284 specimens) and blood culture specimens (178 specimens). The detection rates of pathogens were 8.3% in 2015, 13.3% in 2016, 15.8% in 2017 and 18.1% in 2018, increasing year by year (P<0.05). The top five pathogens ranked by the detection rate were respectively Haemophilus influenzae, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Moraxella catarrhalis. The top five multidrug-resistant organisms ranked by the detection rate were respectively extended-spectrum β-lactamase, methicillin-resistant S. aureus, carbapenem-resistant Enterobacteriaceae, methicillin-resistant coagulase negative Staphylococci and methicillin-resistant Staphylococcus epidermidis, with detection rate of 3.0% in 2015, 3.7% in 2016, 3.2% in 2017 and 2.9% in 2018 (P>0.05). Conclusion: Infection specimens from the infant ward of our hospital are mainly sputum culture specimens, and the detection rate of pathogens is increasing year by year, mainly for Gram-negative bacteria, with multidrug resistance. |
