猪附红细胞体病是由猪附红细胞体引起的,以贫血、黄疸、发热为特征的传染病。几年来,由于猪附红细胞体病的普遍流行,给养猪业带来了很大的经济损失。猪感染附红细胞体后,可导致猪机体抵抗力、免疫力降低,极易引起其他疾病的混合感染。临床上很难准确诊断,引起误诊,导致病情难以控制而暴发,给养殖户带来很大的经济损失。 相似文献

Detection of Eperythrozoon suis DNA from swine blood by whole organism DNA hybridizations 总被引：10，自引：0，他引：10
A procedure is described for isolating Eperythrozoon suis DNA of sufficient quantity and purity to serve as a probe in whole-organism DNA hybridizations for detecting parasitized swine. The E. suis organisms were isolated from the blood of infected swine; the DNA was recovered and digested with restriction endonucleases and resolved on agarose gels. In DNA hybridizations using recovered E. suis DNA, blood samples from parasitized swine could be differentiated from uninfected, control samples. A high salt lysate recovery technique was used in sampling swine whole blood for E. suis DNA and found to offer many advantages in the collection and recovery process. 相似文献

A simple and reliable procedure is described for isolating the cold agglutinins associated with Eperythrozoon suis-infection in swine. After initiating microagglutination by cooling the blood samples, the erythrocytes were separated by density-gradient centrifugation using Ficoll-Paque, resuspended in RPMI-medium and warmed to 40 degrees C. The cold agglutinins could be removed from the supernatant by a subsequent centrifugation. Double immunodiffusion, polyacrylamide gel electrophoresis and immunoblotting showed that the cold agglutinins isolated consisted of IgM antibodies exclusively. Their ability to induce agglutination in cooled erythrocytes from healthy pigs confirmed that they were genuine cold agglutinins. The method paves the way for more detailed investigation into the mechanisms of this agglutinating disease. 相似文献

Evaluation of an enzyme-linked immunosorbent assay for detection of Eperythrozoon suis antibodies in swine. 总被引：17，自引：0，他引：17

An ELISA was developed and tested to detect antibodies to Eperythrozoon suis in swine. Results were compared with those of the indirect hemagglutination (IHA) test. Antigen isolated from swine heavily infected with E suis was used for both tests. Comparison of the ELISA with the IHA test revealed a significant (P less than 0.001) correlation between results. Of 114 samples obtained from 9 swine infected with E suis, 87.7% were seropositive (titer greater than or equal to 200) via the ELISA, and 80.7% were seropositive (titer greater than or equal to 20) via the IHA test. The sensitivity of the ELISA was greater than that of the IHA test. All blood samples obtained from specific-pathogen-free swine tested negative for E suis antibody. Cross-reactions were not observed between E suis antigen and antisera against various swine and cattle disease agents using ELISA. We concluded that the ELISA may be used for rapid and effective diagnosis of infection with E suis in swine. 相似文献

利用半套式PCR扩增16S rRNA基因检测牛和猪附红细胞体 总被引：3，自引：0，他引：3
根据GenBank收录的猪和牛附红细胞体16SrRNA基因序列设计1对通用引物，在其上游引物内侧叉设计1条分别针对猪和牛附红细胞体的特异性引物。以这4条引物对出现附红细胞体痛典型症状及疑似症状的猪和牛的血样DNA进行半套式-PCR扩增。结果显示，该反应阳性率为58．3％，低于临床解剖和镜检结果。对谈基因的序列测定结果进行分析，表明不同动物附红细胞体的16SrRNA基因同源性在80％以上。从谈基因来看，附红细胞体与立克次氏体没有同源性，而与肺炎支原体和穿透支原体亲垮关系较近。 相似文献

Investigations were carried out on the influence of latent and clinically manifest Eperythrozoon suis infection upon haemostasis in swine. The study was carried out with 14 German Landrace pigs. Latent eperythrozoonosis was induced in 7 animals by experimental infection. Splenectomy of these 7 animals and 2 spontaneously infected pigs led to clinical manifestation of eperythrozoonosis. Five clinically healthy pigs were splenectomized and served as controls. In healthy pigs splenectomy was followed by a transient rise in fibrinogen and platelet count. Latent infection with Eperythrozoon suis did not cause an impairment of haemostasis. Acute eperythrozoonosis was associated with increased haemorrhagic tendency considered to be a consequence of intravascular coagulation and subsequent consumption coagulopathy. There was a prolongation of partial thromboplastin time and prothrombin time (Quick) and a decrease of platelet count. Thrombelastography showed prolongation of reaction and clot building time and a short-term decrease of maximum amplitude. Deviation from normal values was proportional to the number of red blood cells infected with Eperythrozoon suis. Anti-rickettsial therapy led to quick normalization of haemostasis. Various aspects of the cause and the consequences of the haemostatic defect are discussed with special regard to the underlying disease. 相似文献

A genomic library to Eperythrozoon suis DNA was constructed in lambda gt11, and from this library, E suis clone KSU-2 was identified as a potential diagnostic probe. In hybridization experiments that used 100-microliters samples of blood collected in chaotropic salt solutions, the KSU-2 probe hybridized strongly with purified E suis organisms and blood samples from splenectomized swine that were parasitized with E suis. However, the probe under stringent conditions did not give radiographic indications of hybridizing with equine blood DNA, bovine blood DNA infected with Anaplasma marginale, canine blood DNA infected with Ehrlichia canis, feline blood DNA infected with Haemobartonella felis, or uninfected swine blood DNA. 相似文献
