海口地区感染性腹泻细菌病原学监测结果分析

Etiology monitoring for infectious diarrhea in Haikou

目的了解海口地区感染性腹泻患者中肠道致病菌的感染状况,为肠道传染病的防治工作提供参考依据。方法于2012年3月至2013年11月将送检的腹泻患者肛拭子标本进行志贺氏菌、沙门氏菌、5种致泻性大肠埃希菌和副溶血弧菌等致泻性弧菌的检测。结果共检测281份标本,检出病原菌58株,阳性率为20.64%,其中副溶血弧菌检出40株,所占比例最大,达68.97%,其次为气单胞菌6株(10.35%),肺炎克雷伯杆菌5株(8.62%),沙门氏菌4株(6.90%),志贺氏菌、类志贺邻单胞菌、河弧菌各1株(1.72%)。结论海口地区感染性腹泻患者肠道病原菌种类较多,以副溶血弧菌的检出率最高,应进行针对性的重点监测。

Objective To understand the infection status of intestinal pathogenic bacteria in the patients of infectious diarrhea in Haikou, and to provide basic data and reference for the prevention and control of intestinal in-fectious diseases. Methods Shigella, Salmonella, and five kinds of E. coli and Vibrio parahaemolyticus causing di-arrhea were detected in the anal swab specimens of patients with diarrhea from March 2012 to November 2013. Results In the 281 samples tested, a total of 58 pathogens were detected, with the positive rate of 20.64%, including 40 strains of Vibrio parahaemolyticus （68.97%）, 6 strains of Aeromonas （10.35%）, 5 strains of Klebsiella pneumoniae （8.62%）, 4 strains of Salmonella （6.90%）, 1 strain of Shigella （1.72%）, 1 strain of Plesimonas shigelloides （1.72%） and 1 strain of Vibrio flurialis （1.72%）. Conclusion There are various kinds of intestinal pathogenic bacteria in patients with infectious diarrhea in Haikou, and Vibrio parahaemolyticus has the highest detection rate, which should be moni-tored specially.
