Analysis Concentration of <i>Toxoplasma gondii</i>on Anti-Toxoplasma IgG-IgM Antibody Levels, and the Outcomes of Pregnancy in Mice Balb/c

Introduction: Toxoplasma gondii is an obligate intracellular protozoan parasite that can infect any warm blood vertebrae, and if first trimester pregnant woman infected, it may cause abortion. The objective is to prove the effect of the Toxoplasma gondii concentration in anti-toxoplasma IgG-IgM antibody levels, and the outcomes of Balb/c mice pregnancies. Materials and Methods: The study was conducted in Balb/c mice with inclusion criteria, and was conditioned pregnant. The pathogen strains of Toxoplasma gondii tachyzoite injected intraperitoneally. The blood samples were taken serially to be tested for anti-toxoplasma IgG-IgM antibody levels. After the mice were injected with tachyzoite, they are assessed every day to observe their body weight, vaginal bleeding, and labor. Anti-toxoplasma IgG-IgM antibody levels examined using qualitative mouse IgG-IgM antibody ELISA KIT. Results: Anti-toxoplasma IgM antibody levels increased significantly after 24 hours of injection tachyzoites in all dose groups, and remained high through day 21. Anti-toxoplasma antibody IgG levels increased significantly after 72 hours post injection and remained elevated until day 21. The incidence of abortion is 100% in mice which injected tachyzoite levels 1 × 103 and 1 × 104, and the incidence of abortion approximately 2 - 4 days post injection. 100% of mice that were injected with tachyzoites 1 × 101 and 1 × 102 have labor at term. Physical anomaly was found in baby mice from mice that were injected with tachyzoite 1 × 102. Conclusion: There is a significant correlation between the concentrations of Toxoplasma gondii tachyzoite with anti-toxoplasma IgG-IgM antibody levels, and there is a significant relationship between the concentrations of tachyzoite with abortion.

不良妊娠结局与弓形虫感染相关性研究

目的探讨十堰地区妇女异常妊娠与弓形虫感染的相关性。方法采用酶联免疫吸附试验检测2007年7月～2010年6月105例异常妊娠孕妇(实验组)及500例正常育龄孕妇(对照组)血清中弓形虫特异性抗体IgM、IgG,并分析两组间感染率的差异。结果异常妊娠孕妇弓形虫IgM、IgG抗体阳性率分别为13.33%和23.81%,而同时间段正常孕妇相应的IgM、IgG抗体阳性率为3.60%和9.80%。异常妊娠孕妇弓形虫IgM、IgG抗体阳性率均明显增高(P<0.001)。结论孕妇弓形虫感染是异常妊娠的重要原因之一,应重视弓形虫感染的早期筛查和诊治。

南京地区孕妇弓形虫感染不同妊娠结局研究

目的探讨孕妇怀孕不同时期弓形虫感染对妊娠结局的影响。方法采用问卷调查、随访和酶联免疫吸附试验(ELISA)检测南京地区6 849名孕妇外周血弓形虫IgG抗体和IgM抗体以及1 032名新生儿脐血弓形虫IgM抗体,并观察孕妇妊娠结局。结果共筛查孕妇6 849例,抗体阳性438例,阳性率为6.4%。其中弓形虫lgM抗体阳性87例,占19.9%;IgG抗体阳性351例,占80.1%。筛查新生儿1 032名,其中正常新生儿组脐血弓形虫IgM抗体阳性率为0.6%,畸形儿组脐血弓形虫IgM抗体阳性率为28.13%,两组差异有统计学意义(P<0.01)。接触动物及不良的饮食习惯(经常在外就餐、喜欢吃烧烤和火锅、喜欢生食肉类、菜板生熟不分等)是导致弓形虫感染的主要传播途径。结论弓形虫感染可导致孕妇不同的妊娠结局,弓形虫lgM抗体检测可能有助于筛选畸形儿。

异常妊娠结局妇女弓形虫感染状况

目的探讨弓形虫感染与异常妊娠结局的关系。方法选择2013年3-12月廊坊市第四人民医院妇产科就诊的126例异常妊娠结局妇女为实验组,本地区263例正常妊娠育龄妇女为对照组,采用酶联免疫吸附试验进行弓形虫IgM、IgG抗体检测,对两组数据进行处理和分析。结果异常妊娠结局妇女弓形虫IgM、IgG阳性率分别为7.94%和19.84%,对照组阳性率分别为1.90%和8.75%,两组差异均有统计学意义(χ2IgM=6.82、χ2IgG=9.70,P均<0.01);对照组弓形虫IgM、IgG阳性率明显低于各异常妊娠结局组,差异均有统计学意义(χ2自然流产=10.40、χ2早产=9.03、χ2胎停=4.32、χ2出生缺陷=4.04,P均<0.05)。4种异常妊娠结局妇女弓形虫IgM、IgG阳性率差异均无统计学意义(P均>0.05)。结论弓形虫感染可致严重异常妊娠结局,应采取综合措施预防孕妇弓形虫感染。
