查询词典 virus

Recombinant plasmid pSVH 7 DNA of avian influenza virus H7 subtype heamagglutinin gene was encapsulated with DC-chol/DOPE liposomes and PC/chol/SA liposomes separately. Two-week old SPF chickens were intramuscularly inoculated with 50 μ g/0.2ml of the liposome entrapped PSVH 7 DNA. Four-weeks later, each chicken was challenged with 0.1ml 〓 AIV . One week after the challenge, the secretion of the cloacas was collected and transfected to chicken embryos to isolate the virus. The virus was isolated from 6/6 of the control group, 1/6 of the naked DNA group, 1/6 of the PC/chol/SA entrapped DNA group and 0/6 of the DC-chol/DOPE liposome entrapped group. The HI antibody titers (log2) of the four groups were 6. 83±0.98, 7. 0±1. 26, 7. 83±1. 17 and 8. 00±0.89 respectively 1-week after challenge, and 8. 5±0.55, 8. 17±0.82, 8. 68±0.45 and 9. 33±0.54 respectively 2-week after challenge. The results showed that inoculation of liposome entrapped DNA significantly enhanced resistance to virosis in animals.

In 1990s, the diseased cases and dead cases were 43.68%and 37.55%of that of the whole year respectively, mixed infection of Hantaan and Seoul virus was found.

结果表明：山东省在60年代和70年代HFRS发病以秋冬季（10月～翌年1月）为主，其发病数占全年发病数的89.87％，病死数占全年的88.99％；疫区限于6个地区，疫区型别为姬鼠型。80年代，除秋冬季发病高峰外，出现春季（3～6月）发病高峰，其发病数和病死数分别占42.78％和21.73％；疫区扩大至全省14个地区，疫区型别为姬鼠型和家鼠型的混合型。90年代情况与80年代类同，春季发病与死亡数分别占全年的43.68％和37.55％；疫区型别仍为混合型。

It was known that ORF of SeMNPV egt was 1572bp long and encodes 523 amino acids through DNAstar software analysis. TATA boxes lies at 48~53 and 68~72bp of the 5'-nonencoding region upstream of a translational start site. Comparing with seven kinds of nuclear polyhedrosis virus and one kind of granulosis virus, it indicated that the SeMNPV egt gene is the highest match the Agrotis setegum nuclear polyhedrosis virus.It has 75% nucleotides and 79% amino acid identity.

采用DNAstar软件分析，与7种核多角体病毒及1种颗粒体病毒egt基因的同源性比较显示，SeMNPV egt基因与核多角体病毒egt序列同源性较高，其中与黄地老虎核型多角体病毒同源性最高，核苷酸和氨基酸序列同源性分别为75%和79%。

So we use all anti-virus biotics to suppress the virus activity, and then HBIG to bind down the residual virus works very well.

所以我们使用抗病毒药物来抑制病毒的活性，然后用乙肝免疫球蛋白来结合残留的病毒，这种办法非常有效。

Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation.

病毒抗原可以从鸭的盲肠，扁桃体，肾脏及粪便分离出来，并且确定这种病毒是高致病性的H5N1，还从血凝素蛋白分解位点推断出病毒的氨基酸序列，为了了解独立群的发病机理，对8只6周龄鸡静脉注射这种病毒，结果所有的均在注射后24小时死亡。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction.
