致病性

As a matter of fact, the viruses of highly pathogenic bird flu do widely spread all over the wildfowl of nature and live together with wildfowl in peace for a long time.

事实是这样的：高致病性禽流感病毒的确广泛存在于自然界的野禽中，与野禽长期和平共处。100多年前，人们开始认识禽流感病毒；50多年前，分离出了H5N1病毒。

Canine Leptospirosis is caused by pathogenic Leptospira as a zoonosis.

犬钩端螺旋体病是由致病性的钩端螺旋体引起的一种人畜共患病。

The pathogenicity of Tetranychus cinnabarinus was studied by using BtR05 strain. Its acaricidal activity was confirmed to prepare BtR05 suspending agent (BtR05 SC). This suspending agent was used to make the indoor toxicity test on the young, nymphae and adult T.

方法］使用BtR05菌株对朱砂叶螨进行致病性研究，确定其杀螨活性后，制备了BtR05悬浮剂，并使用该悬浮剂对朱砂叶螨的幼螨、若螨和成螨进行了室内毒力测定。

In addition to air some of the Central Plains and some micro-organisms (non-pathogenic micro-organisms saprophytic, Bacillus, is Achromobacter, as well as a small number of Streptococcus actinomycetes, yeast and fungi, and so on), there may be from a human body More pathogenic micro-organisms such as Mycobacterium tuberculosis, diphtheria bacteria, Streptococcus, Staphylococcus aureus, meningococcal, influenza virus, measles virus, etc.

除大气中原有的一些微生物（非致病性的腐生微生物、芽胞杆菌属、无色杆菌属、细球菌属以及一些放线菌、酵母菌和真菌等）外，也可能存在来自人体的某些病原微生物（如结核杆菌、白喉杆菌、溶血性链球菌、金黄色葡萄球菌、脑膜炎球菌、感冒病毒、麻疹病毒等）成为空气传播疾病的病原。

In order to discuss the optimal condition in which GPMV proliferates in chicken embryo and its pathogenicity, GPMV of different titer was inoculated into 911-day chicken embryo and the allantoic fluid was harvested after 36, 48, 60, 72 and 84 h, the HA titer was measured as well.

为了探讨鹅副粘病毒在鸡胚中增殖的最佳条件及其致病性，将不同血凝滴度的鹅副粘病毒分别接种于9~11日龄鸡胚尿囊腔，收获孵化36、48、60、72和84 h的鸡胚尿囊液，测定血凝滴度。

Subclinical and clinical genital warts, also known as condylomata acuminata, andvirtually all squamous cell cancers of the anogenital tract are caused by specificHPV types.

由于HPV的致病性与其亚型密切相关，所以对其进行检测和分型对于临床诊断具有重要意义。

The research showed that the pathogenic potential of Helicobacter hepaticus in a mammalian colitis model is altered by the presence of different strains of Bacteroides fragilis .

该研究显示，在哺乳动物结肠炎模型中，当有不同株脆弱类杆菌存在时，有潜在致病性的肝螺杆菌发生了改变。

To test the antibacterial effect of MEBO against anaerobic spore-bearing bacillus, anaerobic non-spore-bearing bacillus (Bacteroides fragilis, propionibacterium acnes) and fungi, etc.

本实验观察了MEBO使厌氧芽胞杆菌——破伤风杆菌、厌氧无芽胞杆菌——脆弱类杆菌和痤疮丙酸杆菌、真菌——白色念珠菌等在形态结构、菌落特点和致病性等方面发生变异。

Objective To set up a fast, sensitive and correct method to detect mycobacterium and drug sensitivity of mycobacterium by using recombinant mycobacteriophages and bioluminescent method.

目的 建立一种特异性强、灵敏度高的致病性分枝杆菌的检测及药敏试验方法。

This test studied some biological and bionomical characteristics of this pest, including life stages,developmental threshold and day-degree requirements,longevity,NO.

本文研究了西花蓟马的生活史、发育起点温度和有效积温、成虫寿命、产卵量和产卵规律、不同虫态的存活率、实验种群生命表、活动习性、危害特点、寄主选择性、种群动态等生物学和生态学特性，调查了西花蓟马在北京的分布、为害规律及嗜食特性等，并对色卡诱集技术、虫生真菌对该虫的致病性等一些防治技术进行了初步研究，主要结果如下。
