Abstract

The commercial norovirus enzyme-linked immunosorbent assay kit was evaluated for its reactivity to recombinant virus-like particles and the detection of natural viruses from stool samples of Japanese infants and children with sporadic acute gastroenteritis compared to reverse transcription-PCR. The kit had a sensitivity of 76.3% and a specificity of 94.9%. Our results clearly indicated that the kit allows the detection of the most prevalent genotype, GII/4. In order to increase the sensitivity of the kit, the reactivity with norovirus of GII/3 and GII/6 genotypes needs to be improved.

摘要

对商用诺如病毒酶联免疫吸附测定试剂盒进行了评估,检测其对重组病毒样颗粒的反应性,并与逆转录聚合酶链反应相比,检测日本散发性急性胃肠炎婴幼儿粪便样本中的天然病毒。该试剂盒的灵敏度为76.3%,特异性为94.9%。我们的结果清楚地表明,该试剂盒能够检测出最常见的基因型GII/4。为了提高该试剂盒的灵敏度,需要提高其对GII/3和GII/6基因型诺如病毒的反应性。
