  pathogen colonization
Thus, milk from these animals or their genetically modified descendants could have a therapeutic effect by inhibiting pathogen colonization and infection.
      
Pathogen colonization of the roots and stems of infected melon plants grown in TP-SCM and OP-SCM composts was significantly lower than that of peat-grown plants.
      
When both of these genetic determinants are present, host defence responses are triggered and pathogen colonization is limited.
      
This difference was apparent in all leaves that allowed pathogen colonization, irrespective of the extent of disease severity.
      
This inhibition reduced the senescence of the flowers, and consequently, the advance in pathogen colonization.

For the purpose of probing into the mechanisms of effects of new prebiotics such as mannanoligosaccharide(MOS) on detachment and immunity regulation of enteric pathogen colonization, the feeding trial of neonate piglets and some other tests such as isolation and identification of pathogenic Escherichia coli and agglutination with bacteria vs swine RBC. Sixty three way crossbred neonate piglets were randomly divided into two groups: the test group was orally administered Bio MOS each day; the control one was administered same volume distilled water as the test one. The trial lasted for 28 days. The results showed that adding Bio MOS to neonate piglets could markedly improve daily gains ( P <0.05), lower the incidence of diarrhea ( P <0.05 ) and strengthen body's cellular and humoral immunity as well as non specific immunity. The isolated pathogenic E. coli could be agglutinated by swine RBC, and this agglutination reaction could be inhibited by mannose, fructose and Bio MOS. This implies that the attachment of the pathogenic E. coli to the intestinal epithelial could be blocked by these sugars, thereby the coliform diarrhea of piglet could be prevented.

为了探讨新型化学益生剂甘露聚糖 -寡糖 (mannanoligosaccharides,MOS)对家畜肠道致病菌的去粘附及免疫调节作用的机制 ,进行了初生仔猪的饲养试验以及致病性大肠肝菌的分离、鉴定及其与猪红细胞的凝集试验 .初生仔猪的饲养试验选用了三元杂交初生仔猪 6 0只 ,随机分成 2组 ,处理组口服 MOS的商品制剂(Bio- MOS) ,对照组则口服同体积的蒸馏水 ,试验期 2 8d.结果表明 ,初生仔猪添加 Bio- MOS,可明显提高仔猪的日增重 (P<0 .0 5) ,降低腹泻发生率 (P<0 .0 5) ,提高机体的细胞免疫和体液免疫水平 .分离到的致病性大肠杆菌可与猪红细胞发生凝集 ,而此凝集反应可被甘露糖、果糖和 Bio- MOS所抑制 .由此可见 ,致病性大肠杆菌粘附于肠上皮的作用可被这些糖类所阻断 ,因而可以预防仔猪的大肠杆菌性腹泻 .

Pathogenicity of Chinese isolates of Gaeumannomyces graminis var. tritici (Ggt)to 24 cultivars of 6 species of turf grass, Poa pratensis, Lolium perenne, Agrostis palustris,Festuca arundinacea,Festuca ovina var. duriuscula , and cynodondactylon , was evaluated by seedling inoculation. The results showed that all of the species of tested turf grass was infected by Ggt and expressed typical symptom of take all disease. The rate and severity of infected root in most of inoculated species and cultivars were very high. Exceptionally,cv.Green Diamond in Agrostis palustris showed moderate resistance to pathogen penetration and high resistance to pathogen colonization, and cv.Shorter of Festuca arundinacea and cv.YS 1 of Festuca ovina spp. duriuscula showed moderate resistance to pathogen colonization. Thus, Ggt was seriously imperilling turf establishment because of its wide distribution and mass production of inocula.

应用人工接种法测定了禾顶囊壳小麦变种中国菌系对草地早熟禾、多年生黑麦草、匍茎剪股颖、高羊茅、硬羊茅和狗牙根等 6种草坪禾草 2 4个品种的致病性。结果表明 ,该菌对供试各草种都能正常致病 ,引起典型全蚀病症状。大多数供试品种的病根率和病根严重度都很高 ,属于感病类型 ,仅匍茎剪股颖的绿宝石品种具有中度抗侵入性和高度抗侵染性 ,高羊茅Shorter品种和硬羊茅参试品种具有中度抗侵染性。由于该菌引起的小麦全蚀病在我国分布广泛 ,可以提供大量菌源侵染草坪禾草 ,从而对草坪构成严重威胁
