一、免疫胶体金技术(一)基本原理免疫胶体金技术的检测原理是以硝酸纤维膜为载体,包被已知抗原或抗体,加入待检样品后,样品中的抗体或抗原与膜上包被的抗原或抗体结合,再通过胶体金标记物与之反应形成红色的可见结果,从而达到检测目的。目前,该项技术已在医学上得到广泛的应用,大多数人的传染病都已经研制成免疫胶体金检测方法。在兽医诊断领域也已开始使用,如犬细小病毒、犬瘟热病毒临床快速诊断均已开始使用免疫胶体金快速诊断试纸条。(二)临床应用1、在我国兽医领域的应用胶体金试纸条作为诊断试剂应用于兽医临床,由于它快速、准确,具有… 相似文献

自从1971年Faulk与Taylor创立胶体金标记技术以来，胶体金被引入免疫化学中，成为继荧光标记、酶标记和放射性免疫标记之后的又一种新型的免疫标记技术。目前该技术在医学快速检验中的应用主要是用于妊娠检测、病原体抗原或抗体检测、药物滥用检测、疾病相关蛋白检测等。该技术在动物疫病诊断方面的应用虽然起步较晚，但发展迅速。其中，免疫胶体金层析技术已成为当今兽医快速检测中最快速敏感的免疫学检测技术之一。 相似文献

免疫胶体金快速诊断技术源于对血清与尿液的绒毛膜促性腺激素的免疫渗滤试验检测,之后有学者提出采用胶体金作为标记物替代酶应用于渗滤试验,并制备完成广泛应用的对抗人类免疫缺陷病毒抗体检测的试剂盒.由于免疫胶体金快速诊断技术方便快捷,已在妊娠试验、检测传染病病原抗体等方面进行应用,而应用于兽医诊断的研究刚刚起步. 相似文献

猪圆环病毒2型抗体免疫金标检测试纸的研制 总被引：2，自引：0，他引：2
应用酶联免疫原理和胶体金层析技术,采用特殊的生产工艺,在玻璃纤维膜包被胶体金标记PCV-2抗原,在硝酸纤维素膜上检测线和对照线处分别包被PCV-2抗原和兔抗PCV-2抗体,制成猪圆环病毒2型抗体免疫金标检测试纸.当待检样品阳性时,在检测线处形成抗原抗体的免疫复合物而凝聚显色;当待检样品阴性时,检测线处不形成抗原抗体免疫复合物不显色.整个试验过程只需15 min.试纸与ELISA试剂比较,两者都具有微量、特异、准确的优点,且金标试纸独具操作方便、快速和结果直观、容易判定的优点. 相似文献

The polymerase chain reaction (PCR) is a nucleic acid-based technique that enables the rapid and sensitive detection of specific micro-organisms. Although this technique is widely used in veterinary research, it has not yet found applications in routine microbiological analysis of veterinary clinical samples. However, advances in sample preparation together with the increasing availability of specific gene sequences will probably lead to the more widespread diagnostic use of PCR in the future. PCR is likely to have a strong impact in the epidemiology, treatment and prevention of animal infectious diseases. 相似文献

Blood transfusions in veterinary medicine have become increasingly more common and are now an integral part of lifesaving and advanced treatment in small and large animals. Important risks associated with transfusion of blood products include the transmission of various infectious diseases. Several guidelines suggest what infectious agents to screen for in canine and feline transfusion medicine. However, while the risk of bacterial contamination of blood products during storage and administration has not been documented in veterinary medicine, it has emerged as a cause of morbidity and mortality in human transfusion medicine. Clinical experience shows that the majority of blood component bacterial contaminations are caused by only a few species. Unlike other types of bacteria, psychrotolerant species like Pseudomonas spp. and Serratia spp. can proliferate during the storage of blood units at 4°C from a very low titer at the time of blood collection to a clinically significant level (> 105 CFU/mL) causing clinical sepsis resulting from red blood cell concentrate transfusions in human medicine. The purpose of this report was to describe the detection and quantification procedures applied in 4 cases of bacterial contamination of canine and feline blood units, which suggest the need for further investigations to optimize patients’ safety in veterinary transfusion medicine. 相似文献

Veterinary practices are unique environments that bring humans into close contact with many different species of animals; therefore, the risk of exposure to infectious pathogens is inherently different in veterinary medicine than in human medicine. In contrast to the risk of exposure to blood in human medicine, infections from zoonotic diseases in veterinary personnel are primarily related to exposure to animal faeces, infected skin, wounds, droplets and puncture wounds. Infection-control measures in veterinary practices are often insufficient to prevent zoonotic disease transmission. The Veterinary Standard Precautions (VSP) Compendium is designed to help prevent transmission of zoonotic pathogens from animal patients to veterinary personnel in private practice. 相似文献

During the last decade enzyme-linked immunosorbent assay has been a technique of major interest to those engaged in immunodiagnostics of human and animal diseases. Owing to its simplicity, specificity and sensitivity it has taken precedence over other conventional assays, including radioimmunoassay on the grounds of freedom from radiation hazards. Many applications of this assay have been developed in veterinary medicine and they are listed in this article. 相似文献

Monoclonal antibody against kanamycin was prepared, and competitive direct ELISA and immunochromatographic assay were developed using the antibody to detect kanamycin in animal plasma and milk. The monoclonal antibody produced was identified to be IgG1, which has a kappa light chain. No cross-reactivity of the antibody was detected with other aminoglycosides, indicating that the monoclonal antibody was highly specific for kanamycin. Based on competitive direct ELISA, the detection limits of kanamycin were determined to be 1.1 ng/ml in PBS, 1.4 ng/ml in plasma, and 1.0 ng/ml in milk. The concentration of intramuscularly injected kanamycin was successfully monitored in rabbit plasma with competitive direct ELISA. Based on the colloidal gold-based immunochromatographic assay, the detection limits of kanamycin were estimated to be about 6-8 ng/ml in PBS, plasma, and milk. The immunochromatographic assay would be suitable for rapid and simple screening of kanamycin residues in veterinary medicine. Screened positives can be confirmed using a more sensitive laboratory method such as competitive direct ELISA. Therefore, the assays developed in this study could be used to complement each other as well as other laboratory findings. Moreover, instead of slaughtering the animals to obtain test samples, these methods could be applied to determine kanamycin concentration in the plasma of live animals. 相似文献
