Cryptosporidium and Giardia are two major protozoa reported from vegetables and environment. The prevalence of these parasites supposes to be different regarding the climate zones. This review aimed to evaluate the prevalence of Cryptosporidium and Giardia in vegetables according to the major climate zones in Iran. The results showed pooled prevalence 7% (95% CI: 2%, 14%) and 4% (95% CI: 3%, 6%) for Cryptosporidium spp., and Giardia spp., respectively. The prevalence of Giardia spp. in mountain, desert and semi-desert, and Mediterranean regions was 4% (95% CI: 2%, 6%), 5% (95% CI: 3%, 8%) and 7% (95% CI: 1%, 18%), respectively. Cryptosporidium spp. was reported 8% (95% CI: 0%, 65%), 6% (95% CI: 0%, 18%) and 4% (95% CI: 0%, 77%) from mountain, desert and semi-desert, and Mediterranean climate zones, respectively. This review suggests the higher prevalence of Giardia and Cryptosporidium in Mediterranean and mountain regions, respectively.

隐孢子虫和贾第鞭毛虫是从蔬菜和环境中报告的两个主要原生动物。这些寄生虫的患病率在气候区方面可能有所不同。这篇综述旨在根据伊朗的主要气候区评估蔬菜中隐孢子虫和贾第鞭毛虫的患病率。结果显示隐孢子虫和贾第虫的合并患病率分别为7％（95％CI：2％，14％）和4％（95％CI：3％，6％）。贾第鞭毛虫的患病率。在山区，沙漠和半沙漠地区以及地中海地区，分别为4％（95％CI：2％，6％），5％（95％CI：3％，8％）和7％（95％CI：1％） ，分别为18％）。隐孢子虫spp。据报告来自山区，沙漠和半干旱地区的8％（95％CI：0％，65％），6％（95％CI：0％，18％）和4％（95％CI：0％，77％）沙漠和地中海气候带。该评价表明，贾第虫和隐孢子虫分别在地中海地区和山区较高。
