The prototypic prion disease found is scrapie . the epidemic of bse in england and the newly found vcjd in human attracted more attention to prion diseases and the disease - causing proteins 羊瘙痒症是最早发现的朊蛋白病，而疯牛病在英国的流行以及新近发现的新变种的人类雅各布氏病引起研究者们对朊蛋白疾病及其致病蛋白的更大关注。
" these include the effectiveness of vaccination in our endemic environment , means to monitor the mutation of the virus and the surveillance system to detect infection of vaccinated chickens from field virus 他说：这些问题包括疫苗针对禽流感已成为风土病的成效，监察病毒变种的方法，以及检验已注射疫苗的鸡只有否感染病毒的制度。
Miscellany - the red corundum grains in some of the ruby . . . zoisite rocks have corona like shell consisting of an off - white to yellowish material that , according to chris wright of wright ' s rock shop , hot springs , arkansas ( personal communication , july , 2005 ) are " variations in the zoisite " 备注：在某些红宝石里有红刚玉的交叉双晶，有的黝帘石岩石有象贝壳样的冠状物，颜色为白色到淡黄色，属于一种变种的黝帘石。
And this virus is an rna virus and as professor tam was saying , the drugs that we re using , it seems to be consistent with our hypothesis and with the classification of this virus . because rna viruses theoretically can be treated with ribavirin , the drug we are using 因为有种影响引致我们的专家有部分估计是一种变种的病菌，我们现时看到的感染，当然一部分是病菌本身，譬如肺炎，通常这种病菌会引致肺炎，另一可能是身体对菌的反应会伤害自己身体。
A dna fragment of 348 - bp amplified from the b subunit gene was cut into two dna fragment of 216 and 132 - bp by haelli . endonuclease restriction analysis of the plasmid content with psti showed that strainas with the same result of southern - blot with spesific probe had the different cleavage pattern . the isolated 285 - bpand 348 - bp dna was ligated with plasmid puc18 . the ligation mixture was used to transform e . coli jm109and the transformants were plated on lb agar containing antibiotics . plasmid dna containing cloned genes were used for direct sequencing 提示1999年的疫情由不同的病原菌引起。另外使用针对志贺毒素2及其变种的引物对进行pcr检测、细菌染色体pst和pcr产物的hae 、 ras酶切分析，以及pcr产物的序列分析，发现2000年从江苏省徐州市患者和家畜家禽粪便标本分离的大肠杆菌o157 ： h7菌株仅仅携带slt2vha基因。
The distribution center of the complex is situated in the area from the yunnan - guizhou plateau to daba mountains . six varieties are recognized , and the other six varieties and one intergeneric hybrid are described here as new . the systematic relationships between varieties were inferred 本研究首次报道了该复合体8个变种的细胞学资料和11个变种的its序列，提出了新的分类标准，确认了6个变种，发现了6个新变种和一个新的天然属间杂交种，并发现了一个新的近缘种(已正式发表) 。
