Aerobe bacteria overgrowth and decreased lactobacillus of the small intestine will strengthen the pathogenicity of gut flora and disturb the absorption of nutrient, resulting in many symptoms related with alcohol. And these changes are result from complex factors not direct effect of acohol.

结论长期饮酒后小肠需氧菌过长、乳酸杆菌减少，增强了肠道细菌的致病性，影响肠腔营养物质的吸收，导致酒精相关的肠道病变的发生，且这种改变是诸多因素共同造成的而非酒精直接作用的结果。

Following confirmation by RFLP and partial sequence analysis, the aliquot mutant viruses (3μg) were used to transfect CEM×174 cell line, and the concentration of SIVmac main core protein(P27) in culture supernatants was closely monitored by enzyme-linked immunosorbent assay in order to identify the replicating ability of the mutants.

一般认为，外膜糖蛋白在病毒的感染和免疫中起重要作用，而SIVmac239和SIVmac142克隆之间envGP区核苷酸的差别，是否提示SIVmac239克隆的致病性或毒力与envGP全区、部分或个别核苷酸有关，仍需要进一步研究〔2，3〕。

The above result strongly indicated that WNJ01 is a potential bioherbicide against alligator weed.

上述结果表明，WNJ01是1种对水花生具有强致病性、环境安全且具有潜在应用价值的生防真菌。

The results showed that calcium signaling pathway was involved in the spore germination and hydrophobic conditions appressorium formation of the regulation.

钙信号传导途径参与稻瘟病菌生长及致病性的调控，获得了潮霉素抗性转化子，转化子在菌丝生长、抱子萌发上与野生型无显著差异。

The role of migratory birds in the spread of highly pathogenic avian influenza is not fully understood.

候鸟在高致病性禽流感病毒的传播中所起的作用还不完全清楚。

In China and description of its morphology: A species of Babesia sp transmitted by Hyalomma anatolicum antolicum were identified and isolated in China.

在我国新疆首次发现了一种由璃眼蜱传播的牛的巴贝斯虫，并对其形态学特性、媒介蜱及致病性进行了描述。

The summary of mechanism of the peroxisome biogenesis in filamentous fungi and relationship between peroxisome and pathogenicity were reviewed in this paper

本文对P发生机制、在丝状真菌中的研究概况，以及与植物病原真菌致病性的关系进行了综述。

A/DK/Hubei/216/83(H7N8) shared 96%～98%homology with different subtypes avian influenza viruses which isolated from HongKong during 1972～1997, in addition, evolutionary analysis showed that the remainingfive gene except NA and PB2, had close phylogenetic relationship with 1972～1997strains. A/DK/Hubei/137/83(H10N4), sequence similarity analysis revealed that theNS, PA, PB1, PB2 gene shared 98%～99% homology with the 1997～2004 H5N1subtype avian influenza virus strains, and except NA and M gene, the other five geneformed independence branch with their own, and the distance between the otherisolates were far.

前者HA氨基酸剪切位点序列为P-E-V-V-Q-G-R，后者HA剪切位点序列为P-E-I-P-K-R；2株病毒的NA在第48位氨基酸后无20个氨基酸的缺失；NS蛋白的第79～84位也没有氨基酸的缺失，不具有高致病性特征；A／DK／Hubei／216／83(H7N8)与香港1972～1997年不同亚型AIV的同源性为96％～98％，进化分析表明，除NA和PB2独自成一支外，其余5个基因都与1972～1997年毒株亲缘关系较近。A／DK／Hubei／137／83(H10N4)除NA和M基因外，其他5个基因分别独立自成一支。
