For evaluation of the prevalence of Cryptosporidium sp. infection in diarrheic and non-diarrheic humans in Iran, fecal specimens from diarrheic (n = 129) and non-diarrheic humans (n = 271) were collected and examined for the presence of Cryptosporidium sp. oocysts. The presence of Cryptosporidium sp. oocysts was determined by Ziehl- Neelsen acid-fast staining. Humans were grouped according to their age as follows: younger than 15, 16-25, 26-35, 36-50, and over 51 years. The results showed that the overall prevalence of infection in all 400 samples was 10.8%, but the prevalence (25.6%) in diarrheic humans was higher than that (3.7%) in non-diarrheic humans. Oocysts of Cryptosporidium sp. were detected in the feces of 21.4%, 9.3%, 8.8%, 6.7% and 5.7% of different age groups, respectively. The intensity of oocysts was significantly higher in diarrheic humans than in non-diarrheic ones. There was a significant association between Cryptosporidium sp. infection and occurrence of diarrhea (P < 0.05). The results indicate that Cryptosporidium sp. infection is prevalent in diarrheic humans in Iran.
为评估伊朗腹泻和非腹泻人群中隐孢子虫属感染的流行情况，收集了腹泻人群（n = 129）和非腹泻人群（n = 271）的粪便标本，检测其中隐孢子虫属卵囊的存在情况。通过齐-尼氏抗酸染色确定隐孢子虫属卵囊的存在。根据年龄将人群分为以下几组：15岁以下、16 - 25岁、26 - 35岁、36 - 50岁和51岁以上。结果显示，所有400份样本的总体感染率为10.8%，但腹泻人群的感染率（25.6%）高于非腹泻人群（3.7%）。不同年龄组粪便中隐孢子虫属卵囊的检出率分别为21.4%、9.3%、8.8%、6.7%和5.7%。腹泻人群中卵囊的强度显著高于非腹泻人群。隐孢子虫属感染与腹泻的发生之间存在显著关联（P < 0.05）。结果表明，隐孢子虫属感染在伊朗腹泻人群中普遍存在。
