    • 摘要: 鸡的7种艾美耳球虫中,巨型艾美耳球虫免疫原性最强。为研究巨型艾美耳球虫激发宿主产生的免疫应答,我们检测了巨型艾美耳球虫3次感染后鸡只的抗体应答及细胞应答特征。 ELISA检测显示,感染鸡只产生了显著高于未感染鸡只的特异性IgY和sIgA (肠道及胆汁)抗体;而酶联免疫斑点法( ELISPOT)检测显示,被感染鸡只脾脏中分泌IFN-γ的球虫特异性淋巴细胞的数量显著高于对照组。粪便中卵囊的检测则显示,第3次感染后的鸡只几乎无卵囊排出,证实巨型艾美耳球虫产生的免疫应答可对同源感染提供完全的免疫保护。%Eimeria maxima is the most immunogenic species within the 7 eimerian parasites of chickens.To study the immune responses of chickens infected with E.maxima, humoral IgY, intestinal mucosa IgA and splenic T cell responses were detected in chickens infected with 3 doses of sporulated oocysts.When comparing to the non-infected chickens, significantly higher level of E.maxima-specific antibodies, i.e., sera IgY, biliary and intestinal sIgA were detected in infected chickens, as well as more IFN-γ-releasing T lymphocytes detected by ELISPOT.We also found that very few oocysts were detected in the feces after the tertiary infection.All these results together demonstrated that E.maxima infection can elite potent immune protection against homologous infection.

    • 摘要: Objective To compare the antibody response between adults with hepatitis B virus(HBV)core antibody(anti-HBc)single positivity and healthy adults after primary immunization and revaccination of hepatitis B vaccine(HepB). Methods Adults aged from 18 to 49 who were both negative for HBV surface antigen(HBsAg)and antibody to HBsAg(anti-HBs),but positive for anti-HBc and narrated no history of HepB immunization by themselves,were selected as single anti-HBc positive group(‘anti-HBc alone’). Adults who were negative for HBsAg,anti-HBs and anti-HBc,with age differences within 2 years,and same gender under the 1 ∶ 1 matching program, were selected to form the control group. Both groups were vaccinated on 0-1-6 schedule with the same HepB. Those who were non-response to HepB at primary immunization were revaccination on 0-1-6 schedule. Response rates and geometric mean concentrations(GMC)between the two groups were compared. Results In total,the number of anticipants were 228 pairs. Rates on non-response, low-response,normal-response and high-response after the primary immunization were 8.77%, 11.84%,31.14%and 48.25%in the control group respectively. The corresponding rates were 8.33%, 30.70%,35.96%and 25.00%in the‘anti-HBc alone’. The rate of low-response in the control group was lower than that in the‘anti-HBc alone’(χ2=22.28,P0.05). Conclusion Immune response in the anti-HBc positive adults after primary immunization was weaker than that in common adults. However,immune response induced by HepB was enough to prevent them from infecting HBV. The rates of response showed an obvious increase after revaccination,hence the same HepB immunization strategy could be used.%目的:探讨单项乙型肝炎(乙肝)病毒核心抗体(抗-HBc)阳性成年人接种乙肝疫苗(HepB)的免疫效果。方法筛选出HBsAg、抗-HBs阴性及抗-HBc阳性,既往无HepB免疫史的18~49岁者组成抗-HBc单项阳性组(单阳组),并按1∶1匹配原则选择对照组。依照“0-1-6”免疫程序对单阳组和对照组接种HepB,对两组无应答者再次按该免疫程序接种HepB,比较两组人群抗-HBs阳转率及其滴度。结果两组人群共调查228对。对照组和单阳组初次免疫抗体阳转率分别为91.23%和91.67%,差异无统计学意义(χ2=0.00,P>0.05)。对照组无应答率、低应答率、正常应答率和高应答率分别为8.77%、11.84%、31.14%和48.25%,单阳组分别为8.33%、30.70%、35.96%和25.00%,对照组低应答率低于单阳组(χ2=22.28,P<0.01),高应答率高于单阳组(χ2=24.43,P<0.01)。初次免疫后对照组抗-HBs几何平均浓度(534.07 mIU/ml)高于单阳组(183.99 mIU/ml),差异有统计学意义(u=4.42,P<0.01);再次免疫1针后,对照组应答率(82.35%)高于单阳组(41.18%)(P<0.05),再免疫3针后两组应答率分别达到90.00%和82.35%(P=1.00)。结论抗-HBc单阳者HepB初次免疫可获得较好的免疫应答,但低于一般人群;初次免疫无应答的抗-HBc单阳者3剂次再免疫可获得较高阳转率。

    • 摘要: 基线抗体浓度和加强免疫后抗体浓度的提高之间存在负相关性的现象以前已有报道。这种受制于数学耦合的相关系数已被统计学家广泛报道,负相关性可部分或全部归因于数学耦合和测量误差(测量中其他短期波动)的联合影响。因此,这一点不是临床上可以解释的。在这项研究中,我们重新分析了在婴儿中接种C群脑膜炎球菌结合疫苗后再于12月龄时加强接种MenCV或A/C脑膜炎球菌多糖疫苗(MenA/C)的5个临床试验中的血清抗体应答。用皮尔逊相关法评估加强接种后和加强接种前相比MenC—IgG浓度相对提高量的效果。在所有组中观察到显著负相关关系,表明高的加强免疫前抗体与加强免疫后抗体的小幅上升是有关的。
