SUMMARY A disease Of new-born piglets characterized by hemorrhagie; diarrhoea and rapid death occured in the rural of Beijing in 1970. Based on the clinical signs and autopsy findings, bacteriologic examinations have been carried out in 53 easses, out of C1. perfringcns type C , and its intestinal toxin content were from 43 casses. Therefore, a diagnosis of Enterotoxemia in piglets hag been established for the first time in China ever ,since.

1970年在北京市郊区发生的新生仔猪拉红稀的急性传染病,在观察了临床症状和病理解剖变化的基础上,经过细菌学检查,53个病例中,有43个分离出C型魏氏梭菌,这些病例的肠内容物中也存在C型魏氏梭菌产生的毒素,结合临床症状和特异的病理解剖变化,确诊为C型魏氏梭菌引起的肠毒血症。群众根据仔猪拉红稀的特征称之为“红痢”,我们沿用了这一为群众惯用的病名,定命为“仔猪红痢”,这是在我国第一次确诊有本病存在。确诊了病原给本病的预防打下了可靠的基础。本病不仅在北京市地区,在其他地方亦有发生。我国发生的仔猪红痢的发病率和死亡率,与H(?)gh,P.报道一的致;其发病的时间和Field,H.I.和Gison,E.A.叙述的相同,我们观察到的仔猪红痢的病理解剖变化,与Hutyra,Marek和Manninger,M(?)esy和Howard,W.Dunne和Alien D.Leman 描绘的一样。据Brooks,M.E.Sterne,M.Warrack,G、H、和Warrack,G.H.以及Sterne,M.Warrack,G.H、等人报道,仔猪红痢病原菌,按Wilsdon分类,属于C型魏氏梭菌,但在次要毒素δ和μ,尤其是δ毒素上与...

The toxin culture filtrate of cotton fusarium wilt pathogen(Fusarium oxysporum f. vasinfectum Suyd et Hans) was resistant tohigh temperature and dilution degree. The wilt index of plants causedby the toxin filtrate treated in 100℃ for 15 minutes was 72.3; thetoxin filtrate of 5% dilution degree was still able to make cotton wilt,and the most suitable concentration for soaking the seedling was 15-25%.The toxin content in the culture filtrate reached the maximum between14th-16th days after culture. The ability of the toxin filtrate causingplant to be wilt was reduced when pH of the toxin filtrate was less than5 or more than 7, and the optimum pH was 5. The toxin activitycould be passivated by ZnSO_4, and inverse ratio was with ZnSO_4concentration within 0.1 - 1.5ppm. There were obvious differences in the wilt indexes and the highestwilting percentage of culture filtrates of different strains. Cotton seedlings were soaked in 15% toxin filtrate for 48 hours.The disease resistance of different varieties was similar to that observedin the fields, When 0.2% rabbit blood dilution was mixed with acetone extract ofcotton shelled seeds, the agglutination of blood cells was seen under themicroscope. The result showed the agglutination ability of rabbit bloodcells was in proportion to the disease resistance of the cotton variety.The disease resistance of different varieties expressed by agglutinationability was similar to that observed in the fields, too.

用棉花枯萎病菌培养的毒素滤液,只有耐高温、耐稀释的特点。100℃处理15分钟,萎蔫指数72.3;5%的稀释度尚能致萎,最适浸苗浓度15~25%,最高产毒期14~16天,pH5的稀释液效果最好,pH5低于5或大于7致萎力都有影响。硫酸锌能鈍化毒素滤液的活性,在0.1ppm~1.5ppm之间随浓度增加而致萎力漸降。致病力不同的培养滤液,其致萎指数及最高致萎百分率有明显差異。用15%毒素滤液浸苗48小时,对棉花不同品种致萎力的差異结果与田间抗性相近。另外,用不同品种的棉籽仁丙酮浸提液与0.2%兔血稀释液混合,在显微镜下观察血球凝集情况,结果证明,凝集力愈强則品种抗性愈强,与田间抗性表现亦近似。

For production of the VD-toxin, 14 strains of V. dahliae with different pathogenicity to cotton plant were grown in Czapek's liquid medium in 250 ml flasks in a shake incubation at 25℃ for 2,4, 8 and 14 days, respectively. The results of the experiments suggested that the VD-toxin content of filtered culture fluids was related to the duration of culture and fungal weight. VD-toxin content in the culture fluids from strains with severe pathogenicity was always higher than that from strains with wild...

For production of the VD-toxin, 14 strains of V. dahliae with different pathogenicity to cotton plant were grown in Czapek's liquid medium in 250 ml flasks in a shake incubation at 25℃ for 2,4, 8 and 14 days, respectively. The results of the experiments suggested that the VD-toxin content of filtered culture fluids was related to the duration of culture and fungal weight. VD-toxin content in the culture fluids from strains with severe pathogenicity was always higher than that from strains with wild pathogenicity.The optimun pH for the prosperous growth of all the strains of Ⅴ. dohliae in the Czapek's liquid medium was from 5 to 9, but when pH reached 3 the growth of those fungi was retarded and also there was no toxin determined. The results also showed, VD-toxin content from strains with severe pathogenicity was obviously higher than that with mild pathogenicity in Czapek's liquid medium with the same pH.

用Czapek’s液体培养基培养的不同致病力类型的14个棉花黄萎病菌(Verticillium dahliae Kleb.)菌株进行毒素产生条件的研究。试验结果表明:各菌株的培养滤液中的毒素含量与培养天数、菌丝量有关。各菌株在pH3的Czapek’s培养液中都不生长。其滤液也不含毒素;在pH5~9的Czapek’s培养液中生长良好,产生毒素量明显增加。在相同pH的Czapek’s培养液中培养结果,致病力强的菌株产生毒素量高于致病力弱的菌株。
