Primary infection with Toxoplasma gondii during pregnancy can pose serious health problems for the fetus. However, the epidemiological status of toxoplasmosis among reproductive-aged population in Myanmar is largely unknown. Although luciferase immunoprecipitation system (LIPS) assays for serodiagnosis of toxoplasmosis was developed mostly using mouse infection model, had not been tested by using field-derived human samples.
A total of 251 serum samples were collected from reproductive-aged women, residing in Shwegyin township, Bago region, Myanmar and analyzed with a commercial ELISA kit, as well as in-house LIPS assays.
The overall seroprevalence for Toxoplasma gondii infection by the commercial ELISA was 11.5%. No clear risk factor was identified except for being in the younger age group (15-30 years old). Overall, LIPS assays showed low sensitivity when the commercial ELSA was used as a reference test.
We identified the epidemiological situation of toxoplasmosis in some rural communities in Myanmar. The data obtained here will serve as a primary information for the effort to reduce toxoplasmosis in this region. Although looked promising in the previous experiments with mouse infection model, we found that the reported LIPS procedures need further improvements to increase the sensitivities.
孕妇初次感染弓形虫可能会给胎儿带来严重的健康问题。然而,缅甸育龄人群弓形虫病的流行状况在很大程度上尚不清楚。尽管用于弓形虫病血清学诊断的荧光素酶免疫沉淀系统(LIPS)检测主要使用鼠感染模型开发,但尚未使用现场采集的人类样本进行测试。
共采集 251 份来自缅甸勃固地区 Shwegyin 镇育龄妇女的血清样本,采用商业 ELISA 试剂盒和内部 LIPS 检测方法进行分析。
商业 ELISA 检测的弓形虫总体血清阳性率为 11.5%。除年龄较小(15-30 岁)外,未发现明确的危险因素。总体而言,当以商业 ELISA 作为参考检测时,LIPS 检测的灵敏度较低。
我们确定了缅甸一些农村社区的弓形虫病流行情况。这里获得的数据将作为该地区减少弓形虫病努力的初步信息。尽管在之前的鼠感染模型实验中表现出良好的前景,但我们发现报告的 LIPS 程序需要进一步改进以提高灵敏度。
