Research Area:Bacteriology
Background:
Helicobacter pylori (H. pylori), a spiral rod shaped gram-negative bacterium, is frequently found in the stomach. In infected populations, 10-20% may develop gastritis and gastric ulcer and 1-2% may develop cancer. The genome of H. pylori isolates from carriers with symptoms contains a 40kb pathogenicity island encoding H. pylori cytotoxin, cytotoxin associated gene A protein (CagA) and other virulence associated factors. CagA is used as a biomarker for virulent H. pylori strains.
Application:
ELISA:HRP conjugated clone 3C1 can be used as detection antibody in sandwich ELISA to detect the recombinant CagA antigen in combination with anti-CagA clone 10E9, or anti- CagA clone 5H10 coated ELISA plate. Application of clone 3C1 in detection of CagA containing H. pylori strain has not been evaluated.

所以说,感染同一种病毒,每个人识别的表位可能不一样。
流感病毒的基因组包含________基因,其中__________蛋白可作为__________的结构基础.
我不知道第一空如何填,第二空是否应该填"HA蛋白"?第3空是否应该填"突变"?
多谢各位啊!
新年快乐!
万事如意!
①乙型肝炎表面抗原—抗体系统(HBsAg/抗—HBs);
②乙型肝炎核心抗原—抗体系统(HBcAg/抗—HBc):
③乙型肝炎e抗原—抗体系统(HBeAg);
④乙型肝炎Dane颗粒抗原—抗体系统
⑤乙型肝炎δ抗原—抗体系统(δ/抗—δ)。
临床意义 1.HBsAg:血清中检测到HBsAg ,表示体内感染了HBV,因而是一种特异性标志。HBsAg阳性见于:①急性乙型肝炎的潜伏期或急性期(大多短期阳性);②HBV致的慢性肝病、迁延性和慢性活动性肝炎、肝炎后肝硬化或原发性肝癌等。③无症状携带者
2.抗HBs:表示曾感染过HBV,不论临床上有无肝炎症状表现,均已得到恢复,并且对HBV有一定的免疫力。
3.HBcAg与抗HBc:由于 HBcAg主要存在于肝细胞核内,并仅存在于Dane颗粒中。因此,对病人血清不能检测HBcAg,而测抗HBc。血清内抗HBc阳性反映:①新近有过HBV感染;②体内有HBV增殖;③有助于诊断急性或慢性乙型肝炎,特别是少数病例就诊时已处于急性恢复期早期,HBsAg已从血中消失,此时血中仅有抗HBc存在,因此,对恢复期患者可作病因追索。
4.HBcAg和抗HBe:HBcAg的存在常表示病人血液有感染性。 HBcAg阳性揭示病人肝脏可能有慢性损害,对预后判断有一定帮助。抗HBe阳性对病人可能有一定的保护力。展开
核心抗原由183个或185个氨基酸组成,高度磷酸化,是乙肝病毒核心颗粒的唯一结构蛋白。正由于它存在于Dane颗粒核心结构表面,被表面抗原覆盖,故不易在血循环中检出。核心抗原具有强免疫原性,可诱导很强的体液免疫和细胞免疫,刺激机体产生抗-HBc。
e抗原为可溶性蛋白质,传染性强,游离存在于血液中,虽然很早就被发现,在病理上认为是HBV复制以具有强感染性的一个指标,但其功能尚不清楚。抗-HBe的出现,是预后良好的征象。向左转|向右转
患者,双手扶墙,脚尖着地;医生做好消毒,戴上手套,利用放血针(可以利用测血糖的放血针),在委中穴点刺放血,利用拔罐器把瘀血抽出来,直到见到新鲜血液为止。委中穴是解毒大穴。
中医强调治症不治病,虽然身体还有病毒,但是,只要症状能够解除,不影响正常生活和工作,就可以了。
需要强调:医生,一定要做好消毒、保护,防止病毒感染。 另外,可以把艾滋病作为一种疫病,尝试五苓散;五苓散是用来治疗疫病的。
