A total of 110 stool samples from out and in-patients from different areas in Great Cairo suffering from diarrhea were examined for parasitic causes. Stool samples were subjected to the direct wet smear method and Sheather's sugar flotation and stained with Giemsa and/or modified Ziehl-Neelsen. Also, stool samples were cultured on agar plates for strongyloidiasis. The overall parasitic infection rate was 60.9% and non parasitic cause was 39.1%. The parasitic infection rate in a descending order was 31.1% for Cryptosporidium parvurnm, 19.8% for Giardia lamblia, 9.9% for Entamaeba histolytica and lastly 1.8% for Strongyloides stercoralis. The main clinical presentation of diarrheic patients in a descending order was vomiting (31.3%), dehydration (29.86%), abdominal pain (29.86%), flatulence (26.86%), anorexia (23.89%), tenesmus (17.9%) and lastly fever (4.47%). The risk factors were living in rural areas, education level, contact with farm animals and/ or pet animals. However, most of these risk factors although showed high percent, yet they occurred in patients with other causes of diarrheas. Artificial breast feeding was not evaluated as only 3 infants had C. parvum compared to non parasitic cause in 1 on the breast feeding.
对来自大开罗不同地区、患有腹泻的110名门诊和住院患者的粪便样本进行了寄生虫病因检查。粪便样本采用直接湿涂片法和谢弗氏糖浮选法处理，并用吉姆萨染色和/或改良齐尔-尼尔森染色。此外，粪便样本在琼脂平板上培养以检测粪类圆线虫病。总体寄生虫感染率为60.9%，非寄生虫病因占39.1%。寄生虫感染率从高到低依次为：微小隐孢子虫31.1%、蓝氏贾第鞭毛虫19.8%、溶组织内阿米巴9.9%，最后是粪类圆线虫1.8%。腹泻患者的主要临床表现从高到低依次为呕吐（31.3%）、脱水（29.86%）、腹痛（29.86%）、肠胃胀气（26.86%）、厌食（23.89%）、里急后重（17.9%），最后是发热（4.47%）。危险因素包括生活在农村地区、教育水平、与农场动物和/或宠物接触。然而，这些危险因素中的大多数虽然占比很高，但也出现在患有其他腹泻病因的患者中。人工母乳喂养未作评估，因为只有3名婴儿感染微小隐孢子虫，而母乳喂养的婴儿中有1名是非寄生虫病因。
