Strain AR-15 penetrated the exodermal passage cells through the velamen cells or root hairs and further infected the cortical cells. There were a number of spores and hyphae in plant roots that was damaged by strain AR-15. Study on the ultrastructure of D. nobile root and its endomycorrhizal formationshowed that the wall of velamen cells of D. nobile root was thin, and there were waxylayers outside of velamen. Cells of exodermis were arranged tidily, having thick wallsand chloroplast.

Many studies have reported that Klebsiella pneumoniae is associated with ankylosing spondylitis but the mechanism of pathogenesis is remained unclear. The endoplasmic reticulum stress would be induced upon exposure of decapsulated KP in HLA-B27 expression B lymphoblast CA46 cells and non-HLA-B27 expression U937 monocytes. Our previous studies demonstrated that decapsulated KP could up-regulate BiP/Grp78 and calreticulin expressions in a dose- and time-dependent manner. We screen more than 60 kinds of traditional herbs and bioactivity agents and we found that berberine,taurine,extracts of Andrographis paniculata Nees.

The results showed:among the 7 isolates, five isolates of HY3、GY1-3、ZJ1-1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.
结果显示:7个菌株中,其中5个菌株HY3、GY1-3、ZJ1-1、HP1、FC3的菌落形态相同:不规则形状、流体、粘性、不透明、表面光滑;另外2个菌株93B、GN1菌落形态相同:不规则形状、干燥、不透明、表面粗糙;用7个菌株接种剪根桉树苗,发病情况非常明显,而自来水对照实验中桉树苗却不发病;无EPS菌悬液培养桉树剪根苗,发病率也很明显,但是相比原菌液,则发病率有不同程度的下降;从7个菌株中间筛选出来2个强致病性菌株和2个弱致病性菌株,用它们配制菌悬液培养桉树苗,设置剪根和不剪根两个处理,每个处理设置五个重复,数据分析结果显示:对于剪根苗,上部和中部、上部和下部的含菌量有显著的差异,中部和下部含菌量差异不显著;带根苗,上部、中部、下部含菌量彼此之间差异显著;不管是剪根苗还是带根苗,木质部和韧皮部含菌量之间的差异都非常显著;上中下与木韧交互作用中,含菌量差异非常显著;最后筛选出来的强弱2个菌株HY3和93B,它们的纤维素酶活性分别为:1.955ug/和1.288ug/,具有显著的差别;果胶酶的活性分别为:1.325 ug/和1.24ug/,没有显著的差别,而且HY3和93B两个菌株细胞分泌的胞外多糖的含量差异很显著,分别为:7.08×10-8ug/cell和5.17×10-8ug/cell。

METHODS: Umbilical cord blood samples were sterilely isolated using Percoll density gradient centrifugation to harvest intermediate layer cells. DMEM medium containing fetal bovine serum, penicillin, streptomycin and L-glutamine was added. Following several adherences and purification, the floating cells were discarded.
