OBJECTIVE
spp. are common parasites and in terms of economics and pathogenicity in domestic animals is important. The purpose of this work was to define the rate of contamination of slaughtered carcasses of cattle to Sarcocystis using digestive and histopathological methods in southeast Iran.
MATERIAL AND METHODS
In this descriptive laboratory study for 1 year, 500 carcasses were examined and isolated bradyzoites Sarcocystis with the digest method. Also, tissue samples from the esophagus and diaphragm were considered for pathologic studies and stained with hematoxylin and eosin of sections of histopathological.
RESULTS
The results showed that the highest contaminations were in imported male animals aged 2-3 years old in the spring. There was a significant difference ( < 0.05) in the prevalence rate with the sex and race of cattle but no significant difference ( > 0.05) in the prevalence rate with age and season.
CONCLUSION
Infection with is common in oxen in this region. The imported cattle are more infected. It seems that racing and the environmental condition affect the prevalence of Sarcocystosis.
目的
肉孢子虫属是常见的寄生虫，在经济和家畜致病性方面具有重要意义。本研究旨在利用消化和组织病理学方法确定伊朗东南部屠宰牛尸体中肉孢子虫的污染率。
材料与方法
在这项为期1年的描述性实验室研究中，对500具尸体进行了检查，并采用消化法分离出肉孢子虫的缓殖子。此外，还对食管和膈肌的组织样本进行病理研究，并用苏木精和伊红对组织病理学切片进行染色。
结果
结果表明，污染率最高的是春季进口的2至3岁雄性动物。牛的性别和品种在患病率上存在显著差异（P<0.05），但年龄和季节在患病率上无显著差异（P>0.05）。
结论
该地区牛感染肉孢子虫很常见。进口牛感染率更高。似乎品种和环境条件会影响肉孢子虫病的患病率。
