Parasitoses are among the most important problems of most countries especially developing countries. We aimed to detect the situation of intestinal parasitic infections in the Farashband district in Fars Province South of Iran and identify influential factors in the escalation of parasitic diseases and to reduce them.
Overall, 1009 participants from the age of 6 months to 90 years were selected from 3 cities and 15 villages of Farashband district, Fars Province South of Iran from 2015 to 2016. Parasitological methods such as the direct assay method, formalin-ether concentration method, and zinc sulfate flotation were used for diagnosis of worm eggs, cysts, and protozoa trophozoite. Susceptible and protozoan positive samples were stained using the Trichrome staining method. The modified acid-fast staining procedure was conducted for diarrheal samples and the results were used for diagnosis of coccidia.
Overall, 313 subjects were infected with at least one intestinal parasite (pathogenic and nonpathogenic). Helminthes infection and protozoan infection were observed in 9 (0.9%) and 304 (30.13%) participants, respectively. Fecal samples of 34 patients with diarrheal feces were used to prepare smears for further examinations using the Ziehl-Neelsen staining method. Examinations showed no infection with coccidia.
Helminthes infection has decreased drastically but protozoan infection is still considered a health issue in this region. It is possible to reduce parasitic infections through proper measures such as increasing public awareness and education the public, especially children on health problems with education courses.
寄生虫病是大多数国家尤其是发展中国家面临的最重要问题之一。我们旨在检测伊朗南部法尔斯省法拉什班德地区肠道寄生虫感染情况，确定寄生虫病流行的影响因素并加以减少。
2015年至2016年，从伊朗南部法尔斯省法拉什班德地区的3个城市和15个村庄选取了1009名年龄在6个月至90岁之间的参与者。采用直接涂片法、甲醛乙醚浓缩法和硫酸锌漂浮法等寄生虫学方法诊断虫卵、囊肿和原生动物滋养体。对易感和原生动物阳性样本采用三色染色法染色。对腹泻样本进行改良抗酸染色程序，结果用于诊断球虫。
总体而言，313名受试者感染了至少一种肠道寄生虫（致病性和非致病性）。分别在9名（0.9%）和304名（30.13%）参与者中观察到蠕虫感染和原生动物感染。使用齐-尼染色法对34例腹泻患者的粪便样本制备涂片进行进一步检查。检查显示未感染球虫。
蠕虫感染已大幅下降，但原生动物感染在该地区仍被视为一个健康问题。通过适当措施，如提高公众意识并通过教育课程对公众尤其是儿童进行健康问题教育，有可能减少寄生虫感染。
