Purpose

Sarcocystis is a zoonotic parasitic pathogen which endangers the safety of meat and meat products. This systematic review and meta-analysis aimed to evaluate the prevalence rate and status of Sarcocystis spp. in ruminants as important food sources in Iran.

Methods

Data were collected from papers indexed in five English language electronic databases (PubMed, Scopus, Web of Science, Science Direct, and Google Scholar) and four Persian electronic databases (IranMedex, SID, IranDoc, and Magiran) from January to April 2019. Papers were selected based on inclusion criteria. Data analysis was performed in StatsDirect statistical software, version 2.7.2.

Results

The searching process resulted in the identification of 73 studies. Data analyses revealed that the total prevalence (95% confidence intervals) of Sarcocystis spp. in Iranian ruminants was 74.40% (64.01–83.56). In addition, a significant association was also observed between sarcocystosis infection in Iranian ruminants and year, host, location, and diagnostic technique (P < 0.001).

Conclusions

According to our data, the prevalence of Sarcocystis infection in ruminants is relatively high. High pathogenicity of some Sarcocystis spp. and the negative impact that the spread of some parasites among ruminants can have on human and animal health necessitate the direction of more attention toward monitoring, controlling, and preventing sarcocystosis.

被忽视的食源性疾病：伊朗反刍动物的囊肿病：系统评价和荟萃分析。

目的

肉囊藻是一种人畜共患的寄生性病原体，危害肉类和肉类产品的安全性。这项系统的审查和荟萃分析旨在评估石蜡囊菌的患病率和状况。反刍动物是伊朗的重要食物来源。

方法

从2019年1月至2019年4月在五个英语电子数据库（PubMed，Scopus，Web of Science，Science Direct和Google Scholar）和四个波斯电子数据库（IranMedex，SID，IrankDoc和Magiran）中索引的论文中收集数据。根据纳入标准进行选择。数据分析在StatsDirect统计软件2.7.2版中进行。

结果

搜索过程确定了73项研究。数据分析显示，Sarcocystis spp的总患病率（95％置信区间）。伊朗反刍动物中有74.40％（64.01–83.56）。此外，在伊朗反刍动物的结节病感染与年份，寄主，位置和诊断技术之间也发现了显着相关性（P  <0.001）。

结论

根据我们的数据，反刍动物中囊藻的感染率较高。一些肉囊藻属的高致病性。反刍动物中某些寄生虫的传播可能对人类和动物健康产生负面影响，因此有必要将更多注意力转向监测，控制和预防结节病。
