为了查明我国奶牛乳房炎无乳链球菌对抗生素耐药情况,指导临床合理用药,从我国部分地区奶牛场采集的临床型奶牛乳房炎病乳中分离鉴定出无乳链球菌115株,采用K-B纸片法测定了这些菌株对抗生素的耐药情况。结果表明,无乳链球菌对目前临床上使用的大部分抗生素,如头孢唑啉、头孢噻肟、丁胺卡那霉素、卡那霉素、庆大霉素、四环素、强力霉素、麦迪霉素、林可霉素、氟苯尼考、多黏菌素B、环丙沙星、氟哌酸、氨苄青霉素/舒巴坦、头孢噻肟/棒酸和头孢他啶/棒酸均比较敏感;但对青霉素G、氨苄青霉素、链霉素、恩诺沙星、阿莫西林/棒酸和复方新诺明等有一定耐药性,其耐药率达50%～100%。 相似文献

为了对从常德市郊某猪场病死仔猪分离的沙门菌进行分离、鉴定及耐药情况检测,试验用世界卫生组织(WHO)推荐的Kirby-Bauer氏法对分离株进行药敏试验。结果表明:从2例病猪体内分离鉴定出4株沙门菌,分离率为26.7%;分离株对环丙沙星、氟哌酸、复达新3种药物敏感,对先锋五号、氨苄西林、头孢呋肟3种药物中介,对复方新诺明、丁胺卡那、强力霉素、庆大霉素、美满霉素、羧苄青霉素、红霉素、青霉素、四环素9种药物产生了耐药性,其中敏感率为20.00%,中介率为20.00%,耐药率为60.00%。 相似文献

本文对来自龙口市不同乡镇的疑似猪链球菌病的病料进行采集,对细菌进行分离培养,运用生化试验和血清学两种方法对分离出的细菌进行鉴定,并对鉴定出来的链球菌进行药敏试验。试验结果表明其形态、染色、培养及生化特性均符合链球菌的特征。该分离菌株对氨苄西林、头孢他啶、万古霉素、头孢氨苄、克林霉素、恩诺沙星高度敏感,对多黏菌素、环丙沙星、卡那霉素中度敏感,对红霉素、青霉素低度敏感,而对土霉素、四环素、强力霉素、复方新诺明有明显耐药性。由此可见,分离出的链球菌对不同药物的敏感性存在显著差异。本文通过对疑似猪链球菌病的病料进行分离和研究鉴定,旨在了解生猪中猪链球菌的分布情况和现状,为防控该病提供理论依据。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2％的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
