为有效控制家畜布鲁氏菌病发生及流行,百色市在1980-2013年期间采取"监测、扑杀病畜、免疫、检疫、消毒、推广人工授精技术"为主的综合防治技术措施进行布鲁氏菌病防治。采用虎红平板凝集、试管凝集试验和细菌分离相结合的检测方法,共对45492份猪血清、7064份牛血清、6604份羊血清以及852份家畜(含血清检测阳性家畜)胎衣、死胎、流产物等组织样本进行布鲁氏菌病抗体和病原的检测和分离。结果显示,1980-2006年监测的38842份猪血清样品中,布鲁氏菌病抗体阳性数526份,阳性率1.35%,其中以1986-1988年年平均阳性率最高,达4.03%;而2007-2013年监测的6650份猪血清,全部为阴性。在2003-2013年检测的7064份牛血清样品和6604份羊血清样品,未发现抗体阳性。对1990-2012年852份家畜(含血清检测阳性家畜)胎衣、死胎、流产物等组织样本进行布鲁氏菌病原分离和鉴定,全部为阴性。依照《布鲁氏菌病防治技术规范》规定,百色市家畜布鲁氏菌病防治工作在2007年后达到稳定控制标准要求,防治效果显著。  相似文献

文章认为,布鲁氏菌病是重要的人畜共患传染病.近年来在内蒙古部分地区的奶牛中不断出现流产、早产、死胎、胎盘滞留的疑似布鲁氏菌病患牛,不仅给奶牛养殖户带来了很大的经济损失,而且还严重威胁着人民群众的身体健康.本试验针对目前内蒙古某些地区疑似奶牛布鲁氏菌病流行的现状,采集患牛流产胎儿的肝、肺、脾等病料及布鲁氏菌血清学检测阳性牛的乳,进行了布鲁氏菌的分离与鉴定.  相似文献

为了研究狂犬病在百色市的流行情况,采集人间狂犬病疫点、交易市场、屠宰场犬的脑组织样品470份,犬唾液拭子178份,从野外采集蝙蝠样品32份。通过RT-PCR方法检测:脑组织阳性样品9份,阳性率达1.9%,唾液和蝙蝠样品均未能检测出阳性材料。小鼠接种成功分离病毒7株。结果表明从表观健康的犬脑组织中带毒现象较多,唾液检出率较低,蝙蝠未检出阳性样品。应切实做好农村犬狂犬病的免疫工作,为防止表观健康犬咬人而引起发病死亡。  相似文献

本文对伤寒LPS-PHA诊断试剂盒进行现场应用评价.来自各医院和不同地区977份不同类型的血清标本作LPS-PHA检测的同时与Widal试验作比较,结果伤寒沙门氏菌血培养阳性46份血清标本前者检出率(86.96%)显著高于后者(67.39%),两者在统计学上有显著差异(X~2=4.999,P<0.025),95份Widal试验阳性血清LPS-PHA阳性率为97.89%,漏检2份系乙型副伤寒抗体阳性者.607份对照血清标本LPS-PHA的假阳性率1.48%,低于Widal试验(4.84%).伤寒LPS-PHA的敏感度和特异度(94.33%和98.52%)高于Widal试验(89. 36%和95.72%).其他5项评价指标(阳性和阴性预示值,粗一致性,调整一致性和约登指数)亦都较Widal试验好.因此,LPS-PHA诊断试剂盒能满足目前临床上早期快速诊断伤寒的要求.但不适用于追溯诊断和血清流行病学调查.  相似文献

Trichloroacetic acid (TCA) solubilized and DEAE fractionatedMycobacterium tuberculosis H37Ra excretory-secretory (ES) antigen viz., Mtb EST DE1 and affinity purified goat antibodies to the TCA solubilized ES antigen (Mtb EST) were explored in detecting tubercular antibody and antigen respectively in sera of bone and joint tuberculosis by indirect and sandwich ELISA. Out of total 36 bone & joint tuberculosis cases, tubercular antibody was detected by indirect ELISA in 30 patients (sensitivity 83%), while circulating tubercular antigen was detected by sandwich ELISA in 27 patients (sensitivity 75%). Out of 34 non tubercular disease control cases, 10 patients showed positive reaction for antibody while only 4 patients showed positive reaction for antigen. In another group of 34 healthy subjects who were screened, 4 individuals showed positive reaction for tubercular antibody and 2 cases for antigen. This study shows that antigen detection assay using affinity purified anti Mtb EST antigen antibody is superior with overall specificity of 91% as compared to antibody detection assay with 75% specificity in bone & joint tuberculosis.  相似文献

A mycobacterial excretory-secretory protein fraction ESAS-7 purified by 50% ammonium sulphate precipitation followed by SDS-PAGE fractionation was evaluated by penicillinase enzyme linked immuno-sorbent assay (ELISA) for its sensitivity and specificity in the diagnosis of pulmonary tuberculosis. At a “cut off” serum dilution of 600, 38 (90%) of 42 sera from bacteriologically confirmed tuberculosis cases, 15 (100%) of 15 sera from bacteriogically negative but anti tubercular therapy (ATT) responded cases, 3 (7%) of 43 sera from normal healthy subjects and 4 (8%) of 48 sera from non tuberculous disease control cases gave positive reaction for tubercular antibody to ESAS-7 antigen fraction containing predominantly 33-kDa protein with a sensitivity of 90% in bacteriologically confirmed cases and specificity of 92%. Further, this diagnostic assay using the ESAS-7 antigen is more sensitive requiring as little as one nanogram antigen per test compared to use of 100 nanogram EST-6 antigen reported earlier. Thus use of ESAS-7 antigen for antibody detection has good diagnostic potential with improved specificity in pulmonary tuberculosis.  相似文献

应用聚合酶链反应(PCR)检测了153例各型乙型肝炎患者的血清HBVDNA,并与ELISA法检测的血清HBeAg和抗HBe结果比较.结果HBeAg阳性89例,PCR法HBVDNA检出率为92.13%;抗HBe阳性27例,PCR法HBVDNA检出率为51.85%;e系统用性37例,PCR法HBVDNA检出率为40.54%.提示抗HBe血清学转换不能作为乙型肝炎病毒复制与非复制、病变活动与静止的唯一指标,而应该用或同时用HBVDNA作为指标才可靠.  相似文献

Effect of magnesium ions on the binding of bilirubin to erythrocytes of different mammalian species, namely, human, buffalo, goat and sheep was studied. Increase in the concentration of magnesium ions led to a gradual increase in the erythrocyte-bound bilirubin in both human and buffalo erythrocytes whereas in sheep and goat erythrocytes, the pronounced increase was found beyond 2.0 and 2.7 mM MgCl2 concentrations respectively. Percentage increase in erythrocyte-bound bilirubin was found highest in human erythrocytes followed by buffalo and sheep erythrocytes and minimum in goat erythrocytes. These differences in the binding of bilirubin to different mammalian erythrocytes can be attributed to the differential shielding effect of metal ions which involves the masking of negatively charged phosphate of phospholipids found on the erythrocyte surface.  相似文献

Sera samples of 7 microscopic haematuria cases collected before and after treatment with Diethylcarbamazine citrate, (DEC), 9 microfilaraemic cases and 19 endemic normal individuals were analysed for filarial antigen and IgG antibody levels. Filarial antigen was detected in 5 of the 7 microscopic haematuria cases, of which 3 turned negative for antigen after treatment with DEC. While none of the 7 haematuria cases were positive for filarial IgG antibodies, before the DEC treatment, all of them turned positive after DEC treatment. The sensitivity and specificity values(to detect mf +ve cases) were 89% and 90% respectively for the detection of filarial antigen and 78% and 95% respectively for the detection of filarial IgG antibodies.  相似文献

Introduction

Screening programs for colorectal cancer (CRC) are mainly based on a first-line fecal immunochemical test for hemoglobin (FIT). Fecal M2-type pyruvate kinase (M2-PK) has been evaluated in clinical settings showing promising results for early CRC detection. However, the impact of fecal M2-PK assessment on the performance of first-round CRC screening programs is not known. We investigated whether fecal M2-PK alone or in combination with FIT may improve CRC screening efficacy in the general population.

Materials and methods

A total of 1027 asymptomatic subjects (median age 66 [59-74] years; females 504 [49.1%]), identified through the general practitioners’ rosters, were invited for the collection of 2 fecal samples for FIT and M2-PK evaluation. Participants with at least positive one fecal test were referred for colonoscopy. Quality indicators for screening performance were calculated and analyzed using Fisher’s exact test.

Results

Overall, 572 subjects underwent both FIT and M2-PK assessment (participation rate 55.7%): 93 participants showed positive results for at least one test (positivity rate 16.3%). Only 10 patients were positive for both tests. Attendance rate to colonoscopy was 86.0% and a total of 65 adenomas and 7 cancers were detected. Combined use of FIT and fecal M2-PK permitted the identification of 18 more neoplasm (25%) without improving colonoscopy workload, as deduced by the comparable number needed to scope (P = 0.402).

Conclusion

The addition of M2-PK testing to FIT offers the potential to detect additional neoplasms that either do not bleed or only bleed intermittently without reducing participation rate and without increasing endoscopy workload.Key words: biomarker, colorectal cancer, occult blood, M2-type pyruvate kinase, screening  相似文献

HER-2 is overexpressed in approximately 20–30% of invasive Breast Cancer. ECD of the HER-2 protein is frequently cleaved and released into the circulation, where it can be detected by ELISA in up to 45% of patients with metastatic breast cancer. The objective of our study was to compare the current methods for the detection of HER-2 protein. Tissue HER-2 levels were studied in 100 breast cancer patients by IHC and compared with serum HER-2 levels by ELISA. IHC frequency was 29%. Serum HER-2 ECD was positive in 42% of patients. A statistically significant correlation was observed. HER-2 detected by IHC correlates significantly with serum HER-2 levels detected by ELISA. Thus, ELISA is a reliable and economical tool to assess the HER-2 status in tumors, when breast tissue sample is not available.  相似文献
