仔猪水肿病又名猪胃肠水肿,是由致病性大肠杆菌的毒素引起的断奶仔猪的一种急性、致死性的疾病.临床上以全身或局部麻痹、共济失调和眼睑部水肿为主要特征.发病率为5%~30%,死亡率达90%以上. 相似文献

猪水肿病的英文缩写为ED(EDEMA DISASE OF SWINE),它是由溶血性大肠杆菌引起的一种高发性疾病,在养殖业中又称肠毒血症。猪水肿病的临床表现为猪的组织器官水肿,具有低发病率和高死亡率的显著特征,在对死亡仔猪进行解剖时可以发现死猪的肠系膜和胃壁具有显著水肿现象。猪水肿病的发病群主要为刚转入肥育群的断奶仔猪或者是断奶5~14d的仔猪。本文就猪水肿病的发病原理、流行病学、临床症状及综合防治等方面展开论述,以期为相关的科研和养殖机构提供借鉴。 相似文献

仔猪水肿病是由溶血性大肠杆菌引起肠毒血症,而使全身毛细血管或小血管受到破坏,通透性增大,水液外渗过多,造成的以头部、眼睑、耳部等处水肿、共济失调和急性死亡为主要特征的急性传染病,又称猪胃肠水肿或猪大肠杆菌肠毒血症,为高度致死性疾病.
1流行特点
本病在春秋两季多发.以4~5月及9~ 10月多见.主要于断奶后1~2周在强壮仔猪中发生.没有规律性.发病率为30%~50%,病死率为80%~100%. 相似文献

正猪水肿病,俗称"摇摆病",是由致病性大肠杆菌毒素引起的疾病,又称猪胃肠水肿。其临床表现为突然发作、共济失调、接触敏感、抽搐、声音嘶哑、眼睑和头部水肿。这种疾病在同样大小的猪和健康快速生长的猪身上发生得更频繁,而断奶仔猪和肥育猪很少发生。1仔猪水肿病的概述仔猪水肿病是当前养猪场在养猪过程中极易遇到的一种疾病,猪患上这种疾病之后的死亡率特别高,高达90%以上。仔猪患水肿病是因为在 相似文献

<正>猪水肿病一般认为是由溶血性大肠杆菌引起的毒血症,常发生在养猪集中地区的断乳后幼猪,体重在20~30kg,特别是膘情好,生长发育快的猪更为常见,1窝猪中生长快的仔猪先发病。以水肿为临床特征,以眼睑、颌下、胸腹下及后肢内侧等较为明显,病程一般3~5d,体重大,水肿轻微的仔猪经3~5d可自愈。体重小,水肿严重仔猪在发病后24~36h内很快死亡。南洋镇龙碾村一养猪场发生了猪水肿病,先后死亡4头,现报告如下。 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
