Besides,interaction of preinvasion of Phytophthora in festans and variousplants was studied by using modified cellulose membrane technique.Potato tuberand leaf promoted both the zoospore germination and appressorium formation,or-ange fruit only promoted the zoospore germination and no effect on appressoriumformation.While onion bulb inhibited the both zoospore germination and appresso-rium formation.

此外，本文利用改进的纤维素膜技术研究了致病疫霉侵入前与15种不同植物之间的相互作用，明确马铃薯块茎和叶片对致病疫霉游动孢子萌发、附着胞形成和侵入丝形成均有促进作用，日本桔果实只对游动孢子萌发有促进作用，对附着胞形成无明显影响，葱和洋葱鳞茎则对游动孢子萌发和附着胞形成均有明显的抑制作用。

The dynamic changes of the number of T or B lymphocytes and the content of immunoglobulin G, IgM, IgA in peripheral blood, the number of CD〓, CD〓 lymphocyte subpopulation, T〓 cells and IgG, IgM, IgA antibody-producing cells, the ratios of CD〓 and CD〓 T cells in immune organs (thymus, bursa of Fabricius and spleen) and immune tissues (cecal tonsils and Harderian glands), the content of IgA, IgM, IgG in local fluid (tear, tracheal fluid, intestinal fluid and bile) of one-day chicks infected with chicken infectious anemia virus and CIAV-infected chicks immunized with Newcastle disease vaccine were determined respectively by immunohistochemistry, immunogold-silves and immunoenzyme staining in order to reveal mechanism of immunopathogenesis of chicks infected with CIAV and influence of immune responses of CIAV-infected chicks to ND vaccine.

The 383 bp fragment is specific to strains of Y.pestis from Marmota baibacina Spermophilus undulates Plague Focus of the Tianshan Mountains and these strains may be the ancestor of Y.pestis in China.

该383bp片段为天山山地灰旱獭、长尾黄鼠鼠疫自然疫源地的鼠疫菌所特有，此疫源地的菌株可能是我国较古老的鼠疫菌。

Under ambient condition of 65±5%RH and 21±2?℃,the fleas sucked blood of Microtus fuscus which contained 10 5 bacteria of Y.pestis/ml for 1.5 hours,and then the suspensions of the fleas were examined with bacteriological methods.

结果 细钩黄鼠蚤的传疫潜能、媒介潜能和感染潜能分别为 0 0 84，34 2 1%，和 3 77%，直缘双蚤指名亚种的传疫潜能、媒介潜能和感染潜能分别为 0 0 6 7，35 5 3%和 12 0 5 %，两种蚤的媒介效能分别为 0 0 3和 0 0 1。

MBC value was 0.61, 0.304, and 0.00475 μgmL^(-1) respectively. Sterilization rate of ceftiofur suspension was the fastest to Actinobacillus, followed by Streptococcus. PAE of ceftiofur suspension was relatively short to E. coli, which illustrated that it was nonconcentration dependent. PAE was obvious longer to Actinobacillus, which showed that it was concentration dependent, however, it revealed part concentration dependent to streptococcus.

头孢噻呋混悬剂对大肠杆菌、放线杆菌及猪兽疫链球菌的MIC值分别为：0.076、0.304、0.00475μgmL^(-1)；MBC值分别为：0.61、0.304、0.00475μgmL^(-1)；头孢噻呋混悬剂对放线杆菌的杀菌速率最快，对链球菌次之；头孢噻呋混悬剂对大肠杆菌PAE较短，呈现非浓度依赖性，对放线杆菌的PAE较长，呈明显的浓度依赖性，而对猪兽疫链球菌呈现部分浓度依赖性。

Of Newcastle disease The cause of Newcastle disease outbreaking in eighteen Parents Broiler Breeder farms and twenty-three flocks were analysed and a integrated measure of biosecurity against were made The integrated measure was applied in 10 farms, and abtained a satisfying result.

通过对青岛地区18个父母代肉种鸡场、23群种鸡发生新城疫疾病的原因分析，制定了种鸡场防治新城疫疾病发生的综合措施，在其中的10个种鸡场推广应用，取得了满意效果结果。
