摘要
目的了解2007年7月至2008年7月间北京大学深圳医院急性感染性腹泻的流行病学特征,以便及时采取措施以防传染病暴发流行。方法选择每日排便≥3次的患者作为研究对象,在患者未使用抗菌药物之前进行大便细菌病原学检验并进行统计分析。结果共检测1017份标本,检出病原菌133株,阳性率为13.07%。133株病原菌中,致病性大肠埃希菌、副溶血弧菌、产毒大肠埃希菌、侵袭性大肠埃希菌、沙门菌分别分离出43株(32.34%)、37株(27.82%)、19株(14.28%)、18株(13.54%)和13株(9.77%)。夏秋季检出肠道致病菌90株(67.66%),高于春冬季节的43株(32.34%)。结论不仅要针对各病原菌检出率的差异在不同季节开展相应的防控措施,还要结合地域的特点对特定的病原菌进行重点监测。
Objective To analyze the epidemiologic characteristics of infectious diarrhea and explore the prevention methods for the prevention of a large-scale outbreak. Methods Between July 2007 and July 2008, patients with a frequency of defecation of 3 times a day were recruited for this study. Bacteriological analysis was performed before and after antibiotics treatment. Results 133 bacterial isolates were obtained from the samples of 1 017 diarrhea patients. The total positive rate of the samples was 13.07%. Of these 133 isolates, 32.34% were enteropathogenic E. coli （EPEC）, 27.82% were V. parahaemolyticus, 14.28% were toxicogenic E. coli, 13.54% were enteroinvasive E. coli and 9.77% were salmonella. 67.66% of these pathogenic bacteria were isolated in summer. Conclusion Appropriate preventive and control measures should be taken throughout the year.
