观察PCV2的病理变化及病毒的免疫组化分析(9000字)
摘  要:目的:为了研究圆环病毒在侵入动物机体内,在被感染动物体内不同组织器官在不同时间病毒分布情况,采用免疫组化的方法在显微镜下观察被感染动物器官病变情况。实验方法:选择刚断奶的清洁级昆明小鼠28只,分为两组:一组为实验组,共21只,腹腔接种PCV-2病毒液0.2ml;一组为对照组,7只,腹腔注射生理盐水0.2ml。将两组昆明小鼠分别饲养于环境条件相同的不同房间内,给予相同的饲料和饮水。7天后,以剪断颈椎的形式将昆明小鼠处死实验组老鼠3只,对照组1只,观察病理变化;14天后再以相同的处死方法处死每组中的4只昆明小鼠,观察病理变化;以此类推,以后每隔7天就如此处死小鼠,直到将所有的昆明小鼠全部处死。然后做石蜡切片,并做免疫组织化学实验检测病毒。结果:圆环病毒能在短时间内侵入动物各主要器官,且在淋巴结、肝部、脾脏病变迅速且明显。结论:PCV2确实能造成小鼠组织器官病变,免疫组化方法可以作为圆环病毒实验室诊断方法。

The Pathological Changes of the PCV2 Infected Mice and Virus Immunohistochemical Detection
Abstract: Objective: to study the wreath virus invades animals' within the infected animal body at different times in different tissues and organs, the virus distribution immunohistochemical method under a microscope disease infected animal organs. Experimental method: choose weaned from kunming mice only clean level 28, divided into two groups: one of the group, a total of 21 only PCV 2 vaccinations, celiac disease venoms 0.2 ml; A group of as control group, seven, intraperitoneal injection saline 0.2 ml. Two groups of kunming mice will be raised in the same environment conditions respectively the different room, give the same feed and drinking water. 7 days, in the form of the cervical spine cut to kunming mice experimental mice 3 only death group, one, the observation pathological changes; 14 days later in the same executed method of executing each group of four kunming mice, observation pathological changes; By analogy, every seven days after death so, until all the mice to be put to death. All the kunming mice Then do paraffin, and do immunohistochemical lab testing virus. Results: wreath virus in such a short period of major organs, invading animals in the lymph nodes, and GanBu, spleen and evident pathological changes quickly. Conclusion: PCV2 can actually cause mouse tissues and organs lesions, immunohistochemical method as wreath virus laboratory diagnostic methods.
