致病性

To study the existence of transfusion transmitted virus in liver tissue taken from the people with no viral hepatitis and it's pathogenicity.

检测非病毒性肝炎人群肝组织中经输血传播病毒感染情况，探讨其致病性。

Under the same eggs inoculation levels,and using such index as root decay,relatively gall index,relatively eggs mass index,shoot height,root length and shoot weight,the pathogenicity for 34 Meloidogyne populations from different areas in 11 provinces in China to the tobacco cultivars K326 and Honghua Dajinyuan were clustered by SAS.

在相同的接种水平下，以烟草品种K326、红花大金元为供试寄主，用SAS软件，对坏死百分率、相对根结指数、相对卵块指数、株高、根长、地上部分重等6个指标进行聚类，分析不同或相似生态条件下，4种常见根结线虫中34个群体的致病性。

Abstract］ The isolation and identification of anaerobic bacteria are often difficult because most of them grow much slower than the facultative or aerobic bacteria.

摘要］ 目前厌氧菌的致病性及其相关研究备受关注，但厌氧菌难培养且时间较长，造成厌氧菌的培养、鉴定和厌氧菌感染的诊断非常困难。

The availibility of the extracted TTV-DNA by the two methods, primers and PCR system was testified by cloning and sequencing the 3' and 5'NCR of patient 72#, who was TTV PCR- positive when used the DNA extracted by STG method. The sequence of 3' and 5'NCR showed 88% of analogy to that of Japanese isolate in the GenBank.

同时，说明用STG法提取的TTV DNA、设计的引物和所用的PCR系统可以有效地用于检测TTV，为今后利用PCR研究TTV的致病性等提供了条件。

Genes involved in interactions among plants and pathogens,pathogenicity related genes,and the genes encoding bactericidal peptide,which have been studied in order to promote resistance to soft rot.

目前已有大量研究证实，利用植物与病原菌互作的相关基因、病原菌致病性的相关基因以及杀菌肽基因可以或有望提高植物对软腐病的抗性。

No month plague, SARS, polio, people infected with highly pathogenic avian influenza, dengue fever, anthrax, diphtheria, neonatal tetanus, leprosy, typhus, kala-azar, echinococcosis and wire Disease cases reported.

当月无鼠疫、传染性非典型肺炎、脊髓灰质炎、人感染高致病性禽流感、登革热、炭疽、白喉、新生儿破伤风、麻风病、斑疹伤寒、黑热病、包虫病和丝虫病病例报告。

Aeromonas hydrophila is a Gram-negative bacterium that is pathogenic in fish, causing motile aeromonad septicaemia. It has been speculated that A.

致病性嗜水气单胞菌(Aeromonas hydrophila，Ah)是我国淡水养殖鱼类的重要病原对其侵袭机制和毒力因子的研究有重要的意义。

Second OO eight years, according to the World Health Organization issued in December, Egypt ASSIUT provinces, Riau Province of Indonesia, Cambodia emerged one after another of human infection with highly pathogenic avian influenza cases.

据世界卫生组织二OO八年十二月发布，埃及ASSIUT省、印度尼西亚廖内省、柬埔寨相继出现了人感染高致病性禽流感病例。

Results Among 11 strains isolated from epidemic asthma-like pneumonia, 4 (36%) had extra six nucleotides inserted into the 3′end non-coding region of the F gene, whereas none of the F genes from 5 strains isolated from regular pneumonia had that insertion.

为了从分子基础来探讨RSV的致病性，本研究室对从不同地区、不同流行特征分离到的RSV进行了主要抗原结构蛋白的基因序列比较分析。

We identified the likely disease-causing mutation by applying genomic methodologies (multiplex target amplification and massively parallel sequencing) to historical specimens from the Romanov branch of the royal family.

我们从皇室家族Romanov一支取得样本，通过遗传学方法（多元靶点扩增和大量平行测序）确定了可能的致病性突变。
