The gene expression profilings in different proglottids of *** were analysed with cDNA microarray of 1080 ESTs from the worm.A total of 4,056 spots including full length and partial complementary DNAs representing novel,known,and control genes were *** showed that 55 genes expression in immature proglottids,134 genes in mature proglottids and 103 genes in gravid proglottids were up-regulated,and that 7 genes in immature proglottids,68 genes in mature proglottids and 78 genes in gravid proglottids were down-regulated compared with control(scolex-neck proglottids).Major function of these genes are about metabolism,transport,protein biosynthesis,transcription factors,apoptosis,cell differentiation,cell communication and nucleic acid binding protein -related *** changes of some genes,such as UBE2A,Carβ,RAD51,DAZ,PKAc and 2 unknown genes were confirmed by Real-time quantitative Polymerase Chain Reaction(RT-PCR).Results provide a frame of gene expression changes in different development proglottids of ***,which may be helpful in understanding the pathogenesis of the worm and studying its genes concerned with reproductive organs development as a model organism.

＜正＞ IntroductionVitellocytes play at least two important functions in parasite embryogenesis: （1） provision and storage of material for the formation of the egg-shell , and （2） provision and storage of nutritive material supply （yolk） for the developing embryo. Thus, the process serves a key role in parasite reproduction. There are several reports on the

一、引言莫氏扩張絛虫是牛、羊的重要寄生絛虫,特别对犢牛和羔羊有致命的危險。在印度的东巴基斯坦,山羊感染达到90%(Rohman,1958)。当莫氏扩張絛虫局限于腸管一定部位时,妨碍宿主食物的順利通过,引起腸管的堵塞,腸套迭,粪滯、腸扭結或... 详细信息

一、引言莫氏扩張絛虫是牛、羊的重要寄生絛虫,特别对犢牛和羔羊有致命的危險。在印度的东巴基斯坦,山羊感染达到90%(Rohman,1958)。当莫氏扩張絛虫局限于腸管一定部位时,妨碍宿主食物的順利通过,引起腸管的堵塞,腸套迭,粪滯、腸扭結或腸破裂。虫体的新陈代謝产物常使宿主产生中毒現象,引起幼畜的发育迟緩,減低宿主对各种有害因素作用的抵抗力,提高宿主对各种續发性傳染病和侵襲病的易感性(1956)。
