流行性乙型腦炎減毒活疫苗國內外不同野毒株的免疫性Should a pandemic strain emerge, slowing its spread will be vital as this could buy valuable time to produce vaccines against the virus and introduce other emergency measures
如出現大流行株,減緩其傳播至關重要,因為這樣可獲取寶貴時間以便針對該病毒生產疫苗和採取其它緊急措施。Two strains of prrsv were isolated from the swine infected with prrsv in shangdong province and daqing area, in order to clarify the source and genetic background of porcine reproductive and respiratory syndrome virus ( prrsv ) from different parts of china, thus providing theoretic basis for the study of vaccine against it. the prrsv was cultured on mark - 145 cells for 5 ~ ~ 6 passages. when the cpe was obvious, the virus was harvested and purified
為了弄清我國不同地區prrsv的來源以及其遺傳學背景,為疫苗學研究提供理論根據,本研究在ch - 1a株完整的基因組獲得以後,從流行於我國山東( sd )和黑龍江大慶( dq )地區疑似prrs的豬體內分離到prrsv ,在mark - 145細胞上盲傳5 6代,細胞出現明顯病變以後,收獲病毒液,然後提純,提取全病毒rna ,經過反轉錄、 pcr擴增獲得結構基因orf2 7的目的基因片斷,然後與pmd - t載體連接,轉化,得到陽性質粒后進行測序,並將其與ch - 1a株進行了比較分析,同時對這兩個毒株的結構基因組的理化性質進行分析。In addition, base on the certain level of genetic differentiation of among the 4 possible natural populations, it is advised that adult plants or seedlings of ginkgo be transplanted mutually in order to enhance the gene flow among them and preserve the genetic diversity of ginkgo furthest
因銀杏群體間已出現了一定程度的遺傳分化,建議在可能的自然群體間進行植株和種子幼苗相互移栽,以增強群體間的基因流,最大限度地保護銀杏的遺傳多樣性。Also, it is based on a irus strain that was circulating in ietnam three years ago
還有,這一疫苗是基於三年前在越南流行的病毒株而研製的。In recent years, the ndv strains isolated in our country mainly belong to group vii, and it was found that sometimes traditional nd vaccine ca n ' t offer solid protection to nd caused by isolates in china
目前,在我國nd免疫預防的過程中,發現常規疫苗對於我國的流行毒株有時不能提供良好的免疫保護,因此尋找一種有效的疫苗是當務之急。London, march 5 ( reuters ) - an experimental bird flu vaccine for humans provides substantial cross - immunity against " drifted " strains of the virus, suggesting it may provide protection in the event of a pandemic, its maker said on monday
倫敦(路透社) 3月5日-一種人用禽流感疫苗經過實驗證實具有免疫能力能對抗「漂浮」病毒菌株,它的發明者星期一發表報道說此疫苗可以提供保護以預防禽流感的流行。Britain ' s glaxosmithkline plc ( gsk. l : quote, profile, research ) said clinical data from two studies showed its pre - pandemic shot was able to recognise and kill an indonesia h5n1 strain that was genetically quite different from the vietnam one included in the vaccine
