为了对种公猪精液中猪繁殖与呼吸障碍综合征病毒带毒情况进行调查,我们对昆明周边地区的部分猪场进行了猪繁殖与呼吸障碍综合征病原调查。从猪场采集了182份样品送往实验室进行RNA提取及PCR扩增,再经琼脂糖凝胶电泳鉴定,其中有64份精液样品中猪繁殖与呼吸障碍综合征病原鉴定为阳性,阳性率为35.16%,提示精液中带毒。该调查为我们后期预防和控制猪场的猪繁殖与呼吸障碍综合征病原提供了一定的基础数据及研究方向。 相似文献

猪繁殖与呼吸综合征(Porcine Reproductive and Respiratory Ryndrome PRRS),又称蓝耳病,发病率高,死亡率高,对猪的养殖会造成巨大的经济损失。为了更好地进行猪繁殖与呼吸综合征的诊断和防制,本文针对吉林省某商品猪繁育场母猪流行繁殖障碍和仔猪发病死亡情况,根据临床症状、剖检病变、实验室检查和实时荧光RT-PCR方法,确诊一起猪繁殖与呼吸综合征。在应用猪繁殖与呼吸综合征灭活疫苗给种猪和保育仔猪免疫接种无效的情况下,通过改用猪繁殖与呼吸综合征活疫苗(R98株)对种猪和保育仔猪免疫接种、加强饲养管理、改善猪舍环境等防制措施,猪繁殖与呼吸综合征的流行得到了有效控制。由于猪繁殖与呼吸综合征的毒力因子现在仍然处于一个不断变化的状态,因此比较难处理,但此次对某商品猪场猪繁殖与呼吸综合征的有效控制,可以为今后该病的诊断和防治提供参考。 相似文献

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献
