  1. Hemagglutinins inhibition ( hi ) testes showed that there were obvious variations among the isolates from different geographical areas. this result explained why the protection rates of current vaccine were different around the country. dna sequence analysis of h9 hemagglutinin genes showed that these viruses were closely related and possibly came from one source

    且在同一地域內，不同的異變體之間的差異較小，隨著時間的推移，其變異並不明顯；但在不同的區域內分離的毒株之間變異較為突出，這表明中國大陸h9n2亞型禽流感病毒不同分離株抗原性是與地域的改變而發生較為明顯的變異。
  2. Hbv genotype was determined by the restriction fragment length polymorphism analysis in patients with chronic hbv infection in 5 cities of fujian province. 2. the sensitivities and specialties of melting curve assay and pcr microplate hybridization - elisa assay were compared with mpcr - rflp and sequence analysis for the detection of hbv ymdd mutants in 44 serums from patients receiving lamivudine monitherapy with viral breakthrough

    應用熔解曲線法和pcr微板核酸雜交- elisa法對44例接受拉米夫定治療過程中出現病毒學反跳時的血清進行ymdd突變株的檢測，並與測序法和mpcr - rflp法比較它們的敏感性、一致性。
  3. Successfully cloned and constructed infectious full - length cdna of attenuated lapinized csfv chinese - strain ( derived from spleen ) could make us get pure rna virus genome of csfv c - strain, and further study and utilize mutation, deletion, insertion and substitution of csfv gene on dna molecular level

    中國豬瘟兔化弱毒（脾淋毒）全長感染性cdna的克隆和構建，可以使我們得到純粹的csfvc -株rna病毒基因組，在dna水平上研究和利用csfv的基因突變、缺失、插入和替換。
  4. The strain is resistant because of a single mutation

    病毒株的抗藥性來自單一突變。
  5. The comparative analysis of sequences indicated that the sequences of meq in different pathotypes are relatively conserved and the homology of the amino acid sequences is very high. the significant differences include two mutations in both mdv - 1 vaccine strains cvi988 / rispens and 814 strain : the deletion of a proline ( no. l93aa ), and this mutation is just exactly located in a 15 - amino - acid ( eelcaqlcstppppi ) repeat sequence within the c - terminal transactivation domain of meq protein ; and a point mutation with a shift from alanine ( a ) of all virulent strains to serine ( s ) was occurred on the no. 71 aa

    結果發現， mdv不同致病型的meq基因序列相對比較保守，它們相互間核苷酸和氨基酸序列的同源性均很高；但是，與所有七個致瘤性的mdv毒株相比，二個型弱毒疫苗cv1988 rispens株和814株均出現了兩個特徵性的突變：即第194位的p缺失性突變和第71位氨基酸由a變成了s的位點突變；缺失性突變恰恰位於meq基因中轉錄激活域內的一個多脯氨酸的重復序列（ pppp ）之中。
  6. Out of the 26 mutants detected by mpcr - rflp, only 16 and 18 mutants were found by melting curve assay and pcr microplate hybridization - elisa, respectively

    5 . 44份出現病毒學反跳的血清，用mpcr一盯lp法檢測26例為ymdd突變株， 18例為野生株。
  7. Some systems allow the irus to infect cells but do not permit prolonged replication and production of irus, while other systems rely on deriaties of permissie irus isolates for efficient replication in transformed ( mutated ) cell lines

    一些培養體系可使病毒感染細胞而不能促進其大量復制繁殖，還有一些培養體系需要誘導劑使病毒在突變細胞株內充分復制。
  8. An influenza pandemic, by definition, occurs only when the influenza virus mutates into something dangerously unfamiliar to our immune systems and yet is able to jump from person to person through a sneeze, cough or touch

    根據定義，全球流感的致病感冒病毒株，是人類免疫系統完全不曾接觸過的危險突變種，能經由噴嚏、咳嗽或接觸而在人與人之間傳播。
  9. The orf1 protein of senv - h12 - 1 isolate was consisted of 675 amino acids and 92 amino - terminal amino acids less than senv - h ( ax025838 ), it had insertion in two sites also. the orf1 protein of senv - h 12 - 2 isolate was 7 amino acids less than senv - h ( ax025838 ) because of deletion. because the first start code was mutated, the orf2 protein of senv - h 12 - 2 isolate started from the second atg code, so that it was 7 amino acids less than senv - h ( ax025838 ) from its n - terminus

    兩個senv - h亞型分離株的情況與已發表的博士學位論文: sen病毒分子病毒學和流行病學研究對sen琴h （ ax025838 ）株分析的結果有所不同: senv - h12一1分離株的orfi僅由675個氨基酸組成，比senv - h （ axo25838 ）的orfi少n一末端的92個氨基酸，此外在2個位點上還存在插入: senv - h12一2分離株在一些位點上的缺失造成o盯1蛋白比senv - h （ axo25838 ）少7個氨基酸，由於第一個起始密碼子發生突變，採用位於下游的第二個起始密碼子使得o即2蛋白比senv - - h （ axo25838 ）少n一末端的7個氨基酸。
  10. It evolves in two ways : gradually through random mutation, and more rapidly as different strains of influenza swap genes inside a single animal or person [ see box on opposite page ]

    病毒可經由兩條演化途徑得到在人類間散播的能力：隨機突變而逐漸適應，更快的是在同一隻動物或人體內與其他流感病毒交換基因（參見右頁全球流感病毒株的衍生途徑） 。
  11. The image reealed that mutations known to play a role in the transmission of aian influenza irus to mammals were located within, or close to, this site of interaction

    這個影象顯示了已知在禽流感病毒到哺動物傳播過程中起重要作用的突變株存在或接近發生這種相互作用的地方
