摘　　要：目的 对马达加斯加共和国马义奇地区的阿米巴痢疾感染状况进行调查分析. 方法 2013年1-12月,在马达加斯加马义奇地区,对中国援马达加斯加医疗队马义奇医院就诊的当地疑似阿米巴痢疾患者,连续采集3次新鲜粪便标本,显微镜检查溶组织阿米巴滋养体和包囊,统计20092012年该院显微镜检查溶组织阿米巴痢疾的原始记录,对各年份及不同季节阿米巴痢疾的感染率、不同年龄组人群患阿米巴痢疾的比率等进行统计学分析. 结果 2009-2013年分别检测疑似患者254、303、320、263和316例,确诊126、152、165、143和176例,感染率分别为49.7％、50.2％、51.5％、54.4％和55.7％,各年份感染率比较差异均无统计学意义（x2=1.46,P＞0.05）.雨季感染率分别为80.2％、78.5％、81.7％、80.3％和82.1％,较旱季明显偏高,各年份雨季和旱季感染率差异均有统计学意义（x2=83.82,P＜0.01）.0～6岁患儿占患者的85.7％,明显高于其他年龄组,各年龄组差异有统计学意义（x2=1 067.6,P＜0.01）. 结论 马达加斯加马义奇地区阿米巴痢疾常年发病,易感人群多为0～6岁的学龄前儿童,且雨季较旱季感染率明显偏高.Objective To investigate the infection of amebic dysentery in Ma Yiqi Region of the Republic of Madagascar.Methods From January to December,2013,the fresh stool specimens of all patients of suspected amebic dysentery,treated by the Chinese medical team assisting to Ma Yiqi Hospital were collected for three times consecutively and were examined for the trophozoites and cysts of histolytic ameba under microscope.Furthermore,all original records of histolytic amebic dysentery confirmed microscopically from 2009 to 2012 in this hospital were summarized.The amebic dysentery infection rate in each year and different seasons and the ratio of different age groups with amebic dysentery were statistically analyzed and epidemiologically studied.Results From 2009 to 2013,254,303,320,263,and 316 cases of suspected patients were detected respectively,among them 126,152,165,152,and 176 cases were confirmed respectively.The infection rates were 49.7％,50.2％,51.5％,54.4％ and 55.7％.Through comparative analysis on the infection rates in each year,the difference showed no statistical significance （x2=1.46,P ＞ 0.05）.The infection rates in rainy season were 80.2％,78.5％,81.7％,80.3％ and 82.1％,they were obviously higher than those in dry season.The diference showed statistical significance （x2=83.82,P ＜ 0.01）.The infection cases in children group aged 0-6 accounted for 85.7％ of the total cases and the infection rate was obviously higher with statistical significance,compared with that in other age groups （x2=1.067.6,P＜0.01）.Conclusion Amebic dysentery attacks all the year round in Ma Yiqi of Madagascar.The children aged 0-6 are most susceptible.The infection rate in rainy season is obviously higher than that in dry season.
