肉食品中住肉孢子虫检测方法探索论文.docVIP

昆 明 学 院 2013 届毕业设计（论文） 设计（论文）题目 肉食品中住肉孢子虫的检测方法探索 姓 名 李红飞 学 号 201022160106 所 属 系 农学院 专业年级 绿色食品生产与检验 指导教师 2013 年 5 月 摘 要 住肉孢子虫（Sarcocystis）是一类人畜共患的寄生原虫，主要寄生在宿主的各类肌肉组织中，其宿主范围很广，包括哺乳类、鸟类、爬虫类以及鱼类。在马、牛、山羊、绵羊、猪、骆驼等家畜以及鸡体内均有不同种类的住肉孢子虫寄生，人也可以被感染。住肉孢子虫寄生在宿主体内可使人、畜、禽等产生住肉孢子虫病，并对其健康造成很大影响，因不断产生代谢废物等也会对肉食品的质量造成不同程度的影响。但目前人们对住肉孢子虫的认识还不普及，更对住肉孢子虫可能对肉类食品乃至人体造成的危害缺乏认识。因此，开展此类研究是有重要意义的。由于住肉孢子虫是寄生原虫且虫体微小，又寄生在宿主的肌肉等组织中而不易被发现，传统检验方法要借助于显微镜等设备在实验室内完成。本实验在传统检验方法的基础上加以改进，以期获得更简单易行的检验方法，为肉食品中的住肉孢子虫检测和保障肉食品安全、优质提供资料和方法支持。此类研究在部分地区存在吃生肉习俗的云南省，就显得更加重要而有意义。 关键词：住肉孢子虫； 危害； 检验方法； 肉食品安全； Abstract Sarcocystis (generic name) is a zoonotic parasitic protozoa, mainly parasitic host various types of muscle tissue, a very wide host range, including mammals, birds, reptiles and fish. Have different types of horses, cattle, goats, sheep, pigs, camels and other livestock and chickens live Sarcocystis parasitism, can also infect people. Sarcocystis parasitic people, livestock, poultry and other meat live cryptosporidiosis in the host body can make a great impact on their health, due to the continuous generation of metabolic waste the quality of the meat will cause varying degrees of . Sarcocystis is not widespread more Sarcocystis possible for meat and even the human body the harm caused by a lack of understanding. Therefore, to carry out such studies is significant. Sarcocystis parasitic protozoa and parasites tiny, and parasites in the host muscle and other tissue not easily found, traditional testing methods with the aid of a microscope and other equipment in the laboratory. This experiment on the basis of the traditional test method to be improved, in order to obtain a more simple test methods, in meat Sarcocystis detect and protect the food safety of meat quality to provide information and support. Such studies exis
