目的了解西南战区部队驻地感染性腹泻病原分布特点,探讨其腹泻病原流行病学特征,为腹泻病的防控提供科学依据。方法按国家“十二五”重大专项传染病监测技术平台《腹泻症候群监测方案》采集部队驻地腹泻病人新鲜粪便标本检测致泻病原。结果从379份腹泻粪便标本中检出21种腹泻病原体191株,检出率为50.40%。病原体顺位依次是变形杆菌、弗劳地枸橼酸杆菌、气单胞菌、肺炎克雷伯菌、沙门菌、EIEC、志贺菌和寄生虫、小肠结肠炎耶尔森菌及其它病原菌。腹泻发病人数15~59岁年龄段最多,其次是5岁以下儿童和60岁以上的人群,6~8月份是发病高峰期。结论引起西南战区部队驻地腹泻的病原菌种类多,有年龄、季节分布的特点。监测中建立的病原谱,对西南战区感染性腹泻病原监测和流行病学调查及制定防控措施提供重要参考。
Objective To understand the distribution characteristics of infectious diarrhea in the troops stationed in the southwest theater and explore the epidemiological characteristics of the diarrhea pathogens so as to provide a scientific basis for the prevention and control of diarrhea. Methods According to the “Twelfth Five-Year” major project of infectious disease monitoring technology platform “diarrhea syndrome monitoring program” to collect fresh stool specimens of resident diarrhea in patients with diarrhea pathogenic bacteria. Results Totally 191 diarrhea pathogens were detected in 379 diarrhea stool samples, the detection rate was 50.40%. The sequence of pathogen was Proteus vulgaris, Citrobacter freundii, Aeromonas sobria, Klebsiella pneumoniae, Salmonella, EIEC, Shigella and parasites, Yersinia enterocolitica and other pathogens. The incidence of diarrhea 15 to 59 years of age the most, followed by children under 5 years of age and over 60 years of age, 6 to August is the peak incidence. Conclusions The types of pathogens causing diarrhea in troops stationed in the southwest theater are many and have the characteristics of age and season distribution. Surveillance established in the pathogenic spectrum of infectious disease in southwest theater of infectious disease surveillance and epidemiological investigation and development of prevention and control measures provide an important reference.
