The possibility of a correlation between dengue virus genotype groups and disease severity is currently under discussion. The objective of this investigation was to identify any immunogenic difference between the American and Asian dengue 2 virus genotypes through the study of antibody development (virus-binding immunoglobulin G and neutralizing antibodies) in mice. Differences in the neutralization pattern between the strains studied were observed, suggesting the presence of slight antigenic variations among them. The lack of recognition of one of the Asian genotype strains was remarkable.
登革热病毒基因型组与疾病严重程度之间存在关联的可能性目前正在讨论中。本研究的目的是通过研究小鼠体内抗体的产生(病毒结合免疫球蛋白G和中和抗体)来确定美洲和亚洲登革热2型病毒基因型之间的任何免疫原性差异。在所研究的毒株之间观察到中和模式的差异,表明它们之间存在轻微的抗原变异。值得注意的是,其中一种亚洲基因型毒株未被识别。
