摘　　要：目的分析湖南省郴州市某医院粪便常规检查中寄生虫感染检出率,为肠道寄生虫病防治提供参考。方法收集2020年9月—2021年3月郴州市某医院就诊患者粪便样本,采用生理盐水涂片法进行肠道寄生虫感染检查,对寄生虫感染阳性率及感染虫种进行分析。结果累计收集10728例患者粪便样本进行肠道寄生虫感染检查,检出寄生虫感染阳性173例,肠道寄生虫总感染率为1.61%,其中3例检出2种寄生虫混合感染;共检出7种寄生虫,包括人芽囊原虫(162例,1.55%)、蓝氏贾第鞭毛虫(5例,0.05%)、脆弱双核阿米巴(5例,0.05%)、微小内蜒阿米巴(1例,0.01%)、布氏嗜碘阿米巴(1例,0.01%)、粪类圆线虫(1例,0.01%)和人毛滴虫(1例,0.01%)。女性肠道寄生虫感染率(2.14%)高于男性(1.25%),差异有统计学意义(χ^(2)=13.01,P<0.01);20~<30岁组(2.99%)和80~岁组(2.86%)就诊患者肠道寄生虫感染率较高,但不同年龄组患者肠道寄生虫感染率差异无统计学意义(χ^(2)=12.45,P>0.05)。结论郴州市某医院就诊人群肠道寄生虫总感染率较低,感染率存在性别差异,感染虫种以人芽囊原虫、蓝氏贾第鞭毛虫和脆弱双核阿米巴等食源性寄生虫或机会性致病原虫为主。Objective To investigate the prevalence of parasitic infections in human stool samples from a hospital in Chen⁃zhou City,Hunan Province,so as to provide insights into the management of intestinal parasitic diseases.Methods Stool sam⁃ples were collected from patients admitted to a hospital in Chenzhou City from September 2020 to March 2021,subjected to phys⁃iological saline smearing and microscopy for detection of intestinal parasites.The prevalence of parasitic infections and the spe⁃cies of parasites were descriptively analyzed.Results The overall prevalence of intestinal parasitic infections was 1.61%in the 10728 stool samples,and there were 3 samples with mixed infections of two parasite species.A total of seven parasite species were identified,including Blastocystis hominis(162 cases,1.55%),Giardia lamblia(5 cases,0.05%),Dientamoeba fragilis(5 cas⁃es,0.05%),Endolimax nana(one case,0.01%),Iodamoeba bütschlii(one case,0.01%),Strongyloides stercoralis(one case,0.01%)and Trichomonas hominis(one case,0.01%).The prevalence of intestinal parasitic infection was significantly higher among women than in men(2.14%vs.1.25%;χ^(2)=13.01,P<0.01),and a high prevalence rate was seen among patients at ages of 20 to 30 years(2.99%)and 80 years and older(2.86%);however,no age⁃specific prevalence of intestinal parasitic infection was detected(χ^(2)=12.45,P>0.05).Conclusions The overall prevalence of intestinal parasitic infection was low among pa⁃tients admitted to a hospital in Chenzhou City,and gender⁃specific prevalence was found.Food⁃borne and opportunistic parasites were predominant intestinal parasites,including B.hominis,G.lamblia and D.fragilis.
