牛气肿疽的防制 总被引:1,自引:0,他引:1
气肿疽 (Gangraena empnyseatosa )又叫黑腿病(Black leg) ,是气肿疽梭菌 (Clostridium chauvoei )引起的一种急性热性不直接传播的传染病 ,呈散发或地方流行性 ,以败血症及深层肌肉发生气肿坏疽为特征。我县部分乡镇是老疫点 ,但都是零星散发 (196 9- 1998年 ) ,通过每年的预防 ,近 2 0年未发现本病。 1998年 10月初至 1999年元月底 ,本县长坪乡黎明等 7个村发生该病 ,通过综合防制 ,取得了显著的效果 ,现报告如下。1 发病情况长坪乡是牛气肿疽老疫点 ,加上 1996 - 1997年两年未搞预防接种 ,导致疫情暴发。 1998年 10月初至1999年元月底… 相似文献

气肿疽又称黑腿病或呜病。主要是牛的一种气肿疽梭菌引起的急性、热性传染病,其特征为肌肉丰满部位发生炎性气性肿胀,并常有跛行。主要侵害1~3岁的黄牛。2004年6月,在新疆昌吉州吉木萨尔县某乡大东沟村牧场发现两头以后肢跛行肿胀为主要特征的病牛,根据临床症状、病理检查和实验室检验结果综合判定,诊断该病为牛气肿疽。鉴于本地区这种极为少见的急性传染病的发生,牧场及周围及时采取了一系列预防措施,使得该病得到了有效的控制。 相似文献

The study was aimed to rapidly diagnose two ill and dead cattle in three bay town of Yanji city in Jilin province.We collected liver,spleen,heart,muscle and other tissues to diagnose Clostridium chauvoei infection by epidemiological investigation,clinical autopsy,microscopic obsevation,bacterial culture observation,biochemical experiment,molecular biology diagnosis and animal experiment.The muscles of the ill and dead cattle contacted with crepitus,and the section had a lot of blood and bubble flowing out,microscopic obsevation found bacillus with obtuse at both ends and spores,the bottom of the tube had loose and white precipitate in the broth,biochemical experiments showed that the isolate had acid-production and gas-production reactions which was unique to anaerobic bacteria causing Clostridium chauvoei infection,and 501 bp fragment was amplified by PCR.The results showed that two ill and dead cattle were casued by Clostridium chauvoei infection in Yanbian area,and proved the existence of Clostridium chauvoei.The test separated Clostridium chauvoei Yanbian strain for the frist time,which provided important reference basis for the prevention and treatment of Clostridium chauvoei infection,and laid the important foundation for the further study of drug and immune preventions of this disease. 相似文献

Clostridium Infection (Jisizheng) in Yaks in Qinghai,China 总被引:1,自引:0,他引:1
Since the mid-1980s, outbreaks of a disease characterized by a sudden onset, acute deaths and extensive haemorrhages in the viscera and digestive tract of yaks have been prevalent in Qilian, Qinghai, China. The disease is known as jisizheng by local people. Virulent Clostridium perfringens type A and Clostridium haemolytica were isolated from yaks that had died of jisizheng. In 1996 and 1997, yaks were immunized with a polyvalent inactivated vaccine against C. perfringens and with an inactivated vaccine against C. haemolyticum, and this prevented the occurrence of jisizheng. 相似文献
