Survey and analysis of common diseases of laboratory monkeys are great significance to understand disease epidemiology, and formulate a set of scientific and reasonable measures for prevention and control disease, to improve the quantity and quality of laboratory monkeys, to ensure the accuracy of the animal experiment results. Through the investigation of the sick and dead animals of a large-scale laboratory monkeys breeding facility in Kunming area in 2014, the animals were classified depends on the main diseases, and the diseases were classified according to adult and juvenile animals, data were analyzed by Excel Office 2010 software. The results showed the common diseases of laboratory monkeys included the digestive system, respiratory system, trauma, reproductive system, and locomotor system disease, which were 47.45%, 13.06%, 12.10%, 11.46% and 8.92% separately; Common diseases included diarrhoea, soft tissue injuries, abortion, lobar pneumonia, dysentery, arthritis, intestinal pneumatosis, chronic colitis, and extreme bad nutrition, the ratio were 18.47%, 11.15%, 8.91%, 8.28%, 8.28%, 7.96%, 5.10%, 5.10% and 5.09% separately. Comprehensive analysis of common diseases and disease occurrence causes of the laboratory monkeys, suggesting that providing better quality laboratory monkeys for scientific research only by constantly improving the scientific breeding management level, constantly strengthening veterinary capacity, mastering the theoretical knowledge and scientific diagnosis method.  相似文献

本研究应用PCR方法检测了中国3种旧大陆猴(恒河猴、食蟹猴及藏酋猴)的TRIMCyp嵌合基因型个体的存在状况,并首次发现携带TRIMCyp嵌合基因中国品系恒河猴。同时本实验应用建立RT-PCR方法在mRNA水平上进一步检测了恒河猴和食蟹猴的TRIMCyp嵌合基因序列和特性。其编码的融合蛋白TRIMCyp丧失了对HIV-1复制的限制功能,推测具有该基因型旧大陆猴对HIV-1更易感,可用于建立新型的艾滋病非人灵长类动物模型。本研究结果将促进逆转录病毒跨种间传播的研究和建立HIV-1易感非人灵长类动物模型。  相似文献

BACKGROUND: Guidelines published by the Food and Drug Administration and Center for Human Medicinal Products describe the need to assess immunotoxic effects in nonclinical studies that evaluate drug toxicity, including the use of immunophenotyping to measure immunotoxicity. We are not aware of previous studies, however, that have validated methods for immunophenotyping peripheral blood lymphocyte subsets in whole blood samples from cynomolgus monkeys. OBJECTIVE: The purpose of this study was to optimize and validate a flow cytometric assay for immunophenotyping lymphocytes in the peripheral blood of cynomolgus monkeys. METHODS: A series of prevalidation experiments were done to determine optimal reagents, volumes, timing, and other procedural details of the flow cytometric assay. Using the optimized method, we then determined precision, interindividual variation, laboratory-to-laboratory variability, and sample stability. Stabilized human blood was used as a positive control for staining, processing, and analysis. The percentage and number of pan-T cells (CD3+), T-helper cells (CD3+4+), T cytotoxic/suppressor cells (CD3+8+), natural killer cells (CD3-16+), and B-cells (CD3-20+) were determined in 146 male and 140 female, clinically healthy monkeys and reference intervals were calculated. RESULTS: By doing 4-color staining with a lyse-wash method, intra- and interassay precision were <5% for all lymphocyte subsets. Variability between technicians and laboratories was minimal (CVs<3%). Samples were stable for up to 24 hours after staining and fixing. CONCLUSIONS: The validated method is extremely robust and can be performed under good laboratory practice conditions to support nonclinical studies. Reference intervals for lymphocyte subsets were similar to those previously reported.  相似文献

为了解实验猴间日疟原虫感染的基本情况,为猕猴属动物或其他非人类灵长类实验动物间日疟原虫病的防治提供参考。通过酶联免疫吸附试验(ELISA)的检测方法,对采自云南昆明某灵长类研究中心的3种实验猴(恒河猴、豚尾猴、食蟹猴)的血清样品进行间日疟原虫抗原检测。结果,3种实验猴的间日疟原虫血清阳性率平均为1. 62%,其中,豚尾猴的血清阳性率最高为5. 62%,其次恒河猴的血清阳性率为0. 94%,食蟹猴的血清阳性率为0%,3种实验猴的血清阳性率有显著差异(P=0. 004 <0. 05);从性别分析,公猴(2. 89%)和母猴(0. 94%)的血清阳性率之间无显著差异(P=0. 101> 0. 05);从年龄分析,青年猴(≤4岁)血清阳性率为3. 07%,成年猴(> 4岁)血清阳性率为0%,也存在显著性差异(P=0. 007 <0. 05)。从回归分析结果来看,品种因素是引起实验猴感染间日疟原虫的主要风险因子(P=0. 004 <0. 05)。结果表明,该灵长类研究中心的实验猴存在间日疟原虫感染,带虫猴会成为潜在的内部感染源。饲养人员需要加强对实验猴的饲养管理及间日疟原虫的防治工作,提高实验猴质量。  相似文献

Cynomolgus macaques (also known as longtail or crab-eating macaques) Macaca fascicularis, are an important non-human primate model for biomedical research. Using a case study involving a suspected occurrence of twin birth, we demonstrate that the highly polymorphic human variable-number tandem repeat (VNTR) mini-satellite probes D1S7, D2S44, D3S42 and D4S184 can be successfully employed as a rapid screening strategy to complement husbandry records in order to establish genetic relatedness in a captive colony.  相似文献

结核分支杆菌H37Rv株的全基因组序列解码加速了对重组抗原的克隆和表达,LAM、38 ku抗原1、6 ku抗原、ESAT-6、CFP-10和Mtb8.4等特异性抗原的出现,弥补了经典抗原OT和PPD在实际应用中的不足,丰富了TST、LTT、ELISA和IFN-γ检测等诊断方法的内容,提高了检测的准确性。论文结合免疫学诊断抗原在各诊断方法中的应用,概括分析了各抗原的敏感性和特异性。鉴于检测经费、仪器设备和检测频率的限制,目前TST仍是实验猴场最实用的监测方法,而其他诊断方法在阳性猴的确诊和实验室研究中仍发挥着重要作用。  相似文献

A loop-mediated isothermal amplification (LAMP) assay was developed for detection of Salmonlla in fecal samples of experimental monkeys. According to the specific sequences (fimY) of Salmonlla in GenBank, one set of primers was selected and the reaction condition was optimized. The results showed that the detection limit of LAMP method was 1.35×101 and 1.35×103 CFU/mL in Salmonella pure culture and clinical samples,respectively,which was the same as routine PCR. The amplification could complete in one hour, and the result could be distinguished by naked eyes. There was non-specific amplification of other pathogens. These results suggested that this LAMP assay was a simple and specific method for rapid detection of Salmonlla in fecal samples.  相似文献
