The purpose of this study was to evaluate the prevalence of intestinal parasites in 277 healthy subjects in the city of Mamuras (Albania, South Eastern Europe) and the correlation between parasitic infections and possible risk factors. Faecal samples collected with sodium-acetate-formalin fixative were concentrated by formalin ethylacetate sedimentation and examined as wet mounts, permanent stains and by anti-Giardia/Cryptosporidium fluorescent antibodies. Data concerning age, sex, level of education, availability of piped water, number of people living in the same house, and residence in rural or urban area were collected for each subject. Statistical analysis was performed by chi-square test and regression logistic analysis. The overall prevalence of intestinal parasites was 183/277 (66.06%). In particular, pathogenic protozoa or helminths were found in 67 subjects (24.18%), including Trichuris trichiura in 34 (12.27%), Giardia duodenalis in 31 (11.19%), Hymenolepis nana in 5 (1.8%), Ascaris lumbricoides in 3 (1.08%). A significant correlation was observed only between parasite colonization and older age and between Trichuris trichiura infection and residence in rural areas.
本研究旨在评估阿尔巴尼亚（欧洲东南部）马穆拉斯市277名健康受试者肠道寄生虫的流行情况，以及寄生虫感染与可能的风险因素之间的相关性。用乙酸钠 - 甲醛固定剂采集的粪便样本，通过甲醛 - 乙酸乙酯沉淀法浓缩，并制成湿涂片、永久染色片，并用抗贾第虫/隐孢子虫荧光抗体进行检测。收集了每个受试者的年龄、性别、教育程度、自来水供应情况、同住人数以及农村或城市居住情况等数据。采用卡方检验和回归逻辑分析进行统计分析。肠道寄生虫的总体患病率为183/277（66.06%）。具体而言，在67名受试者（24.18%）中发现了致病性原生动物或蠕虫，其中34名（12.27%）感染了鞭虫，31名（11.19%）感染了十二指肠贾第虫，5名（1.8%）感染了微小膜壳绦虫，3名（1.08%）感染了蛔虫。仅观察到寄生虫定植与年龄较大之间以及鞭虫感染与农村居住之间存在显著相关性。
