猫乳腺瘤的发病率仅次于皮肤癌和淋巴肉瘤，与犬乳腺肿瘤的发生率相比较，猫的发病率不及其半。然而，犬的乳腺肿瘤509／6以上是良性的，与其相反猫的乳腺肿瘤709／6～90％为恶性的、转移性的；在肿瘤间质和实质细胞间，常有淋巴细胞浸润；淋巴转移常发生在腋下淋巴结、腹股沟淋巴结、肺、肝及脾，骨骼的转移性肿瘤很少见。 相似文献

犬、猫乳腺是肿瘤的常发部位。犬猫乳腺瘤易发年龄均为10～11岁。由于乳腺瘤的破害性大,因此本文通过对犬猫动物乳腺瘤的诊治的介绍,为从事兽医临床或者想了解这方面病症的人提供参考。 相似文献

<正>犬乳腺瘤是兽医临床上较为常见的一种肿瘤性疾病,约占犬肿瘤发病数的1/4～1/2。其中,约40%～50%的犬乳腺肿块为良性,即为纤维腺瘤。犬的乳腺瘤易发年龄约为10～11岁,5岁以内的犬不易发。母犬多发,占母犬肿瘤性疾病总发病率的50%,占母犬生殖系统疾病的82%。公犬极少发,一旦发生则极可能是恶性肿 相似文献

近年来，随着宠物热的兴起，猫乳腺肿瘤的病例明显增加。与其它动物相比，猫乳腺瘤和乳腺癌多为恶性，若不及时治疗，则可能发生转移，进而导致动物死亡。笔者曾遇到该类病5例，现总结如下。 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
