The evolutionary trees of SARS - CoV and SARS - like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

结果：发现两次SARS自然流行的病毒可分为两个明显不同的聚类；第二次流行时从人类中分离的SARS冠状病毒和从果子狸等动物中分离的SARS样冠状病毒可分为两个基因型，两型的主要鉴别依据是病毒的全基因组变异而非Spike基因序列。

Was presented in 12 cases (24%) by bacterial isolation. By in-situ hybridization, PCV2 signals were chiefly distributed in interstitial and necrotic lesions, and the positive signals could be found in macrophages-like cells and necrotic debris. PRRSV signals were mainly located at interstitial lesions and alveolar wall, and the positive signals could be found in macrophages-like cells and epithelial cells of alveoli. Swine influenza virus could be found in interstitial and necrotizing lesions, and the signals could be found in macrophages-like cells, and epithelial cells of terminal bronchiole and alveoli.

另运用原位杂交法对PCV2、PRRSV及猪流行性感冒病毒进行检测，结果发现PCV2主要分布於PNP的间质及坏死病灶区，并能於肺泡及终末细支气管上皮细胞、巨噬细胞与坏死细胞碎片皆可见有病毒核酸；PRRSV则多分布於间质病灶区及肺泡壁处，能於巨噬细胞与肺泡上皮细胞见到病毒核酸；SIV则存在於间质及坏死病灶区，且能於肺泡及终末细支气管上皮细胞与巨噬细胞见有病毒核酸。

According to standards of virus classification, it is proved that the isolate was budgerigar fledgling disease virus which had placed into the Polyomavirus genus of Papovaviridae.

根据病毒分类的标准确认为澳州长尾小鹦鹉幼雏病病毒，应归属于乳多空病毒科多瘤病毒属。

Transmission of infection from body to body as a result of sexual intercourse is one of the principal ways in which viruses such as herpes 1 and 2, HIV, cytomegalovirus, hepatitis B and the like, and venereal bacterial disease such as gonorrhea, chancroid, streptococcus, staphylococcus, gardnerella, mycobacteria, etc are spread.

由性行为所导致的人体之间的感染传播，是疱疹病毒1或2、艾滋病病毒、巨细胞病毒、乙型肝炎等类似病毒，以及淋病双球菌、软性下疳、链球菌、葡萄球菌、加德纳菌、分枝杆菌等性细菌广泛传播的主要方式之一。

Methods A recombinant antisense GFAP retrovirus was developed. After packing and concentrating, the suspension of this retrovirus was injected into the sites of injured brain stab by a microinjector. The effect of recombinant antisense GFAP retrovirus on formation of glial cicatrix in the injured sites was studied through immunohischemistry and morphological observation.

构建反义GFAP逆转录病毒表达载体，经过病毒包装后，将获得的病毒上清液浓缩并通过微量注射的方法，引入大鼠脑穿刺损伤灶内，采用免疫组化及形态学观察的方法，研究重组反义GFAP逆转录病毒对脑损伤后胶质瘢痕形成的影响。

It belongs to a group of viruses that includes the smallpox virus, the virus used in the smallpox vaccine, and the cowpox virus.

它属于一个包括天花病毒、在天花疫苗中采用的病毒和牛痘病毒的病毒组。

These viruses are Beet Mosaic Virus,Cucumber Mosaic Virus and an isolate of Furoviruses.

这些病毒是甜菜花叶病毒，黄瓜花叶病毒和真菌传杆状病毒属分离物。

For the soybean germplasms, 76(25.33%), 41(13.67%) and 14 (4.67%) were positive to Soybean mosaic virus, Cucumber mosaic virus, and Alfalfa mosaic virus respectively.

结果表明：在大豆种质中检测出大豆花叶病毒、黄瓜花叶病毒、苜蓿花叶病毒三种病毒，阳性检出率分别为25.33%（76份）、13.67%（41份）和4.67%（14份）。

Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.

然后，通过与ONYX-015（E1B 55 KD a蛋白缺失的2型和5型嵌和型腺病毒，美国ONYX生化制药公司研制）、wtAd5进行对比，利用病毒增殖实验和细胞生长抑制实验，验证了CNHK500选择性增殖能力和肿瘤特异性杀伤作用；利用Western Blot检测CNHK500腺病毒E1A和E1B在乳腺癌细胞和正常成纤维细胞中的表达差异，揭示了腺病毒肿瘤靶向性的机制；利用携带绿色荧光蛋白的CNHK500-EGFP感染乳腺癌细胞株和正常成纤维细胞株，直观地观察其感染乳腺癌细胞的能力和在乳腺癌细胞中的增殖过程。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
