布氏杆菌病注苗牛与自然感染牛三种检查方法的比较 总被引：3，自引：0，他引：3
向湘春 《江西畜牧兽医杂志》1999,(3):37-37
我国规定布氏杆菌病为每年畜牧业必检项目。然而由于对一些家畜实行注射布氏杆菌菌苗进行防疫，故在生产实践中难以区分注苗牛和自然感染牛的区别。作者用利凡诺尔（Ｒｉｖａｎｌ）试管凝集试验法（简称利凡诺尔法）、试管凝集试验法（简称试管法）、以及虎红平板凝集试验... 相似文献

为了解曲靖市麒麟区三宝街道羊布氏杆菌病的流行情况,防控羊布氏杆菌病。连续3年共采集羊血清20 258份,采用虎红平板凝集和试管凝集试验方法,进行血清学调查,筛选出布氏杆菌病阳性羊群,再从阳性群中筛选出阳性个体,对阳性个体进行无害化处理,最终达到消除羊布氏杆菌病的目的。试验结果显示,试验区域存在羊布氏杆菌病,2020年、2021年、2022年的个体感染率分别为3.47%、1.03%、0.81%,通过逐年排查及血清学调查,筛选出阳性个体并进行无害化处理,可以逐步净化消除。该试验可为羊布氏杆菌病的科学防控提供参考。 相似文献

The results of a survey which included the testing of 21,275 blood samples collected at various slaughter houses are described.
Sixty-three herds had a single reactor with a titre of 1:100 or higher to a tube or plate agglutination test. Investigations in forty-five of these herds failed to detect the presence of brucellosis in the remaining mature swine.
The prompt slaughter of the reactors may have eliminated possible sources of infection.

A national survey was conducted in 1985 to investigate the brucellosis status of the Canadian swine herd. Serum samples were collected from cull sows slaughtered over a forty week period in 1985; 15,707 samples were suitable for brucellosis testing, and 48 (0.31%) gave some degree of reaction on the buffered plate agglutination screening test. All 48 samples were negative on the 2-mercaptoethanol and modified complement fixation test. We therefore conclude that the Canadian swine herd remains free of brucellosis. 相似文献

为探索操作简便、快速、实用的奶牛布病诊断方法,本研究建立了奶牛布鲁氏菌病(布病)诊断96孔V型板微量凝集方法,并优化了试验条件。结果显示,抗原的最佳稀释浓度为1:20,反应最适温度为37℃,反应时间为24 h;为验证本研究建立的微量凝集方法的准确性,对120份奶牛布病虎红平板凝集试验阳性血清样品进行微量法凝集和试管凝集试验,结果显示,微量法与虎红平板凝集试验的符合率为83.3%,试管法与虎红平板凝集试验符合率为80.0%。提示,微量凝集试验可以作为试管凝集试验的替代方法,应用于规模化奶牛场布病的诊断和检疫。 相似文献

Brucella preferentially infects cattle, swine, sheep, and goats. However, some epidemiological surveys have been carried out to investigate nonruminants, such as horses. Horse brucellosis has been found in clinical cases, but there are few epidemiologic patterns. Between May 2008 and April 2009, a total of 120 horses were screened for brucella infections in Mashhad, Iran, by the rose bengal test and the tube agglutination test. Sera from three horses were found positive by rose bengal test and tube agglutination test, and therefore the prevalence rate was 2.5%. In horses, the highest individual seroprevalence was in an animal kept close under the intensive system, with other animals such as cattle, sheep, and goats. The zoonotic aspects of brucellosis from the horse must, therefore, be considered because the disease is important from a public health standpoint. The present study documents the first serological evidence of Brucella spp. infection in horses in Iran. 相似文献

采用虎红平板凝集试验(RBPT)和试管凝集试验(SAT)对塔城市10个乡镇场社区27个村队巷1207份未免疫布病疫苗的牛血清进行监测,检出阳性65头,阳性率为5.4%。阳性牛分布在8个乡镇场社区的27个村队巷。出现布病疫情主要原因是,传染源没有彻底清除,市场交易频繁,大量外引牲畜未得到有效检疫,饲养者缺乏对布病知识的了解致使阳性畜不断增加,导致疫情扩散。采取检疫、净化与扑杀无害化处理相结合的方式,淘汰病畜,加强牲畜流通环节监管,加大宣传,以控制疫情蔓延。 相似文献

几种布鲁氏菌病血清学诊断方法的比较研究 总被引：11，自引：1，他引：11
疑似布病感染的牛场采集牛奶和全血进行细菌分离,采集血清用虎红平板凝集试验(RBT)、试管凝集试验(SAT)、iELISA、cELISA进行抗体检测;采集免疫牛场和部分免疫羊场血清430份进行国内4个厂家生产的RBT抗原比对实验,并且选择特异性最高厂家的RBT抗原与SAT、iELISA和cELISA同时进行抗体检测。结果表明4个厂家生产的RBT抗原检测结果的一致性较差,RBT和SAT与加拿大布病参考实验室提供的iELISA和cELISA试剂盒检测结果相比一致率较高,但前两者均有较高的假阳性和假阴性。通过对比试验得出:在布病检疫时可选择特异性好的RBT抗原进行初筛,阳性结果用iELISA或cELISA进行确诊。 相似文献

Seven of 18 elk on a deer farm were found by the official Rose‐Bengal agglutination test (RBT) and tube agglutination test to be brucellosis reactors/suspects. Evaluation with the competitive ELISA (C‐ELISA) and the fluorescence polarization assay (FPA) tests revealed that six and five sera were positive respectively. The seven reactors/ suspects were slaughtered and their blood and tissues were collected. Brucella species could be isolated from three of the slaughtered animals, with nine isolates being obtained from the popliteal, supramammary and submandibular lymph nodes, vaginal discharge, mammary tissue and spleen. Brucella genus‐specific PCR based on 16S rRNA and AMOS‐PCR, which is specific for differential Brucella species, revealed that all nine isolates were Brucella abortus. These nine were further confirmed to be B. abortus biovar 1 by classical biotyping scheme assays. This is the first report of an outbreak of brucellosis in domestic elk in Korea. Our observations suggest that deer should be included in the routine Brucella surveillance programme for the effective control and prevention of brucellosis in Korea. 相似文献

One group of 28,714 bovine sera were tested by both the brucellosis tube serum agglutination test and the brucellosis card test. The tube serum agglutination test confirmed 99.8% of the negative brucellosis card test results. The brucellosis card test identified 63% of the tube serum agglutination test reactors. In a second group of 496 sera reacting to either the tube serum agglutination test, complement fixation test, plate serum agglutination test or acid antigen serum agglutination test the brucellosis card test identified 99.1% of the complement fixation test positive sera and 91.3% of the sera reacting to any of the other serological tests. The brucellosis card test showed satisfactory agreement with both the complement fixation test and tube serum agglutination test. It appears to be a useful screening test in operations involving large numbers of animals since under these conditions the reactors can be quickly identified and isolated. 相似文献
