This chapter presents the basic biology and husbandry of mink as they have been used in commercial production units. Clinical laboratory data are summarized. Veterinary care is divided into viral and bacterial diseases along with several noninfectious disease sections. 相似文献

Thirty mink infected with Aleutian disease virus (ADV) were found to have elevated levels of antibody to double-stranded DNA (dsDNA) in their sera when compared to 30 healthy mink. The anti-dsDNA antibody levels in the diseased mink were, however, not found to correlate with the total amount of immunoglobulin. This was a common observation for all autoantibodies tested. The concentration of rheumatoid factors of IgG class, but not those of IgM class, was found to be significantly higher in the diseased mink at the chosen level of significance (P less than 0.01). IgG antibodies to thyroglobulin were likewise significantly higher in the ADV-infected mink. Unexpectedly, we found IgG antibodies with specificities for cardiolipin and mitochondrial antigens to be significantly higher in healthy mink than in ADV-infected mink. This difference is especially remarkable since the serum immunoglobulin concentration of the ADV-infected mink was three times higher than the serum immunoglobulin concentration of the normal mink. 相似文献

Poisoning occurred in 32 mink fed diets containing meat from cows which had been fed a polychlorinated biphenyl (PCB), Aroclor 1254. No live kits were produced and all adult mink died during a 105 day period of feeding a ration containing 3.57 ppm of PCB. At a level of 0.64 ppm of PCB in ration one of 12 mink produced three kits, all of which died during the first day after birth. Clinical signs were limited to weight loss and passage of black tarry feces. The gross lesions seen were yellowish discoloration of the liver and hemorrhage into the abdominal cavity or gastrointestinal tract. Microscopic lesions were nephrosis, fatty de-generation and necrosis of the liver, brain edema, disseminated intravascular coagulation, and fibrosis of coronary arteries. It is concluded that mink are highly sensitive to small quantities of PCB fed for an extended period of time. 相似文献

下载免费PDF全文 Cultures of mink testis and mink kidney cells were inoculated with 10% extracts and filtrates of tissue from plasmacytosis-affected mink. Specific morphological changes were observed in cultures of kidney and testis cells. Millipore filtration experiments suggested the size range of the agent to be from 10 to 50 mμ. Inoculation of fluids from the 2nd, 4th and 8th tissue culture passages of the agent induced plasmacytosis in adult mink. 相似文献

为获得对水貂具有免疫刺激活性的CpG ODN序列,设计合成了45种含不同CpG基序的DNA序列,应用MTS比色法测定合成CpG ODNs刺激水貂PBMC增殖的能力,结果有11条CpG ODN对水貂PBMC有刺激活性（SI＞2）;应用SI值大于5的6种CpG ODN分别与水貂伪狂犬灭活疫苗联合免疫水貂,免疫后经水貂血清抗伪狂犬中和抗体效价测定和水貂PBMC非特异性增殖效应检测,结果有3个CpG ODN序列对水貂具有较好免疫增强作用,分别是CpG-21(ATCGATTTGTCGTTATCGAT)、CpG-23(ATCGATGAACGTTAACGTTTC)和CpG-24(AACGTTCATCGATATCGATGT)。本研究获得3条对水貂具有较好免疫刺激活性的CpG ODN序列,可为水貂新型CpG佐剂的研究提供参考。 相似文献
