OBJECTIVE
To study risk factors for the highly variable local colonization rates with unrelated Enterobacter species strains previously found in 22 Swedish neonatal units (0% to 32.4% of the infants).
PATIENTS AND SETTING
The fecal Enterobacter species carriage rates among 953 infants in the 22 special-care neonatal units were correlated with variables related to the ward (size, crowding, staffing, work load, antibiotic usage, level of care, hygienic precautions), and the hospital (temperature of water supplied, geographical location).
RESULTS
The average Enterobacter species carriage rate was highest at seven days of age (17% of the infants) and then declined to 3%. Only location of the hospital in an area with warmer climate according to horticultural zone showed an association with Enterobacter species carriage in multivariate analysis (P = 0.005).
CONCLUSION
Although Enterobacter species mainly cause nosocomially acquired infections, the occurrence of the organism in special-care neonatal units seemed to be determined more by extrahospital than by intrahospital factors.
目的
研究先前在瑞典22家新生儿病房发现的非相关肠杆菌属菌株局部定植率高度可变的风险因素（占婴儿的0%至32.4%）。
患者与研究背景
22家特殊护理新生儿病房的953名婴儿的粪便中肠杆菌属携带率与病房相关变量（规模、拥挤程度、人员配备、工作量、抗生素使用情况、护理水平、卫生预防措施）以及医院相关变量（供水温度、地理位置）相关。
结果
肠杆菌属平均携带率在7日龄时最高（占婴儿的17%），随后降至3%。多变量分析显示，仅根据园艺区划分，医院位于气候较温暖地区与肠杆菌属携带有关（P = 0.005）。
结论
尽管肠杆菌属主要引起医院获得性感染，但特殊护理新生儿病房中该微生物的出现似乎更多地由医院外因素而非医院内因素决定。
